A solar-powered microgrid project backed with funding from the Biden administration aims to reduce energy burdens and provide backup power to a tiny northern Minnesota tribal community.

The Pine Point Resilience Hub would serve an elementary school and community center in Pine Point, an Anishinaabe village of about 330 people on the White Earth Reservation.

In June, the project was selected to receive $1.75 million from the U.S. Department of Energy’s Energy Storage for Social Equity (ES4SE) Program, which helps underserved and frontline communities leverage energy storage to make electricity more affordable and reliable. It’s part of a slew of Biden administration funding related to grid resilience and energy equity that has spurred several tribal microgrid projects across the country.

The developers, locally owned 8th Fire Solar and San Francisco-based 10Power, hope to finish the project next year, and have also secured funding from Minnesota’s Solar for Schools program and foundation grants but said they still need to raise about $1 million. They’re also counting on receiving about $1.5 million in federal tax credits, which face an uncertain future with the incoming Trump administration. 

“The idea of the microgrid is to help with infrastructure,” said Gwe Gasco, a member of the White Earth Nation and the program coordinator with 8th Fire Solar, a thermal solar company based on the reservation.

Tribal communities were largely bypassed during the massive, federally funded push under the Rural Electrification Act of 1936 to bring electricity to remote rural areas of the country. As a result, grid infrastructure on many reservations remains insufficient to this day, with an estimated 1 in 7 Native American households on reservations lacking electricity connections, and many more contending with unreliable service.

On top of higher-than-average electric reliability issues, tribal communities also generally pay higher rates for electricity and face higher energy burdens due to poverty and substandard housing.

On the White Earth Reservation, these challenges are most pronounced in Pine Point, where one-third of residents live in poverty. Gasco said the area is among the first to suffer from outages, with eleven occurring over the last five years, according to the Itasca-Mantrap Electric Cooperative that serves the area.

The Pine Point Resilience Hub project will build on an existing 21-kilowatt solar array, adding another 500 kilowatts of solar capacity along with a 2.76 megawatt-hour battery storage system, enough to provide about 12 hours worth of backup power for residents to be able to charge cell phones, power medical equipment, or stay warm in the event of a power outage.

Gasco said the microgrid could be especially important in the winter, given the area’s “brutally cold” weather and reliance on electric heat. They also hope it will reduce utility costs, though they are still negotiating with the local electric co-op on rates for power the system sends and receives from the utility’s grid. Itasca-Mantrap President and CEO Christine Fox said it doesn’t set net metering rates, which are determined by its electricity supplier.

The project developers hope to qualify for additional federal tax credits by using equipment largely produced in the U.S., including Minnesota-built Heliene solar panels, inverters made in Massachusetts, and Ohio-produced solar racks.

The developers have partnered with the Pine Point School District, which plans to incorporate the microgrid into an Ojibwe-language curriculum on renewable energy. A monitoring interface will allow students to see real-time data in the classroom.

“It’s powerful to me that this (project) is at a school where we’re hoping to inspire the next generation of kids,” said Sandra Kwak, CEO and founder of 10Power, a for-profit company that specializes in developing renewable energy projects in tribal communities.

Corey Orehek, senior business developer for Ziegler Energy Solutions, which has been hired to do the installation, said they plan to work with a local community college to train students for solar jobs. 

“One of the things that we want to drive in this is workforce development,” Orehek said. “We want to leave something that’s not only a project that’ll last 30 years but provide the training and experience for community members to either start their own energy companies or become contractors in the clean energy workforce.”

The resilience hub is the second such project announced by a Minnesota tribe in just recent months. The Red Lake Nation received $3.15 million from the U.S. Department of Energy’s Local Government Energy Program in late September for a behind-the-meter microgrid project at a secondary school.

The Shakopee Mdewakanton Sioux Community is also working with Minnesota Valley Electric Cooperative to build a $9 million microgrid with U.S. Department of Energy funding. The electric cooperative will install a 4 megawatt-hour energy storage system and add a 1 megawatt solar system at the reservation in suburban Minneapolis.

It’s unclear whether federal funding for such projects will continue in President-elect Trump’s second term, but for now tribal energy advocates see microgrids as a good solution to both lower energy burdens and improve reliability.   

“This is a great opportunity to create a success story in terms of leveraging cutting-edge technology, being able to help frontline communities, and for tribes and co-ops to work together,” Kwak said.

Seventeen days after Hurricane Helene devastated Western North Carolina, tearing down power lines, destroying water mains, and disabling cell phone towers, the signs of relief were hard to miss. 

Trucks formed a caravan along Interstate 40, filled with camouflaged soldiers, large square tanks of water, and essentials from pet food to diapers. In towns, roadside signs — official versions emblazoned with nonprofit relief logos and wooden makeshift ones scrawled with paint — advertised free food and water. 

And then there were the generators. 

The noisy machines powered the trailers where Asheville residents sought showers, weeks after the city’s water system failed. They fueled the food trucks delivering hot meals to the thousands without working stoves. They filtered water for communities to drink and flush toilets. 

Western North Carolina is far from unique. In the wake of disaster, generators are a staple of relief efforts around the globe. But across the region, a New Orleans-based nonprofit is working to displace as many of these fossil fuel burners as they can, swapping in batteries charged with solar panels instead. 

It’s the largest response effort the Footprint Project has ever deployed in its short life, and organizers hope the impact will extend far into the future. 

“If we can get this sustainable tech in fast, then when the real rebuild happens, there’s a whole new conversation that wouldn’t have happened if we were just doing the same thing that we did every time,” said Will Heegaard, operations director for the organization.  

“Responders use what they know works, and our job is to get them stuff that works better than single-use fossil fuels do,” he said. “And then, they can start asking for that. It trickles up to a systems change.” 

A ‘no-brainer’ solution to the problem of gas generators 

The rationale for diesel and gas generators is simple: they’re widely available. They’re relatively easy to operate. Assuming fuel is available, they can run 24-7, keeping people warm, fed, and connected to their loved ones even when the electric grid is down. Indubitably, they save lives.  

But they’re not without downsides. The burning of fossil fuels causes not just more just more carbon that exacerbates the climate crisis, but smog and soot-forming air pollutants that can trigger asthma attacks and other respiratory problems.  

In Puerto Rico after Hurricane Maria, generators were so prevalent after the electric grid failed that harmful air pollution in San Juan soared above the safe legal limit. The risk is especially acute for sensitive populations who turn to generators for powering vital equipment like oxygenators. 

There are also practical challenges. Generators aren’t cheap, retailing at big box stores for more than $1,000. Once initial fuel supplies run out — as happened in parts of Western North Carolina in the immediate aftermath of Helene — it can be difficult and costly to find more. And the machines are noisy, potentially harming health and creating more stress for aid workers and the people they serve. 

Heegaard witnessed these challenges firsthand in Guinea in 2016 when he was responding to an Ebola outbreak. A paramedic, his job was to train locals to collect blood samples and store them in generator-powered refrigerators that would be motorcycled to the city of Conakry for testing. He had a grant to give cash reimbursements to the lab techs for the fuel. 

“This is so hard already, and the idea of doing a cash reimbursement in a super poor rural country for gas generators seems really hard,” Heegaard recalled thinking. “I had heard of solar refrigerators. I asked the local logistician in Conakry, ‘Are these things even possible?’”  

The next day, the logistician said they were. They could be installed within a month. “It was just a no-brainer,” said Heegaard. “The only reason we hadn’t done it is the grant wasn’t written that way.” 

‘Game changing for a response’

Two years later, the Footprint Project was born of that experience. With just seven full-time staff, the group cycles in workers in the wake of disaster, partnering up with local solar companies, nonprofits and others, to gather supplies and distribute as many as they can. 

They deploy solar-powered charging stations, water filtration systems, and other so-called climate tech to communities who need it most — starting with those without power, water, or a generator at all, and extending to those looking to offset their fossil fuel combustion.

The group has now built nearly 50 such solar-powered microgrids in the region, from Lake Junaluska to Linville Falls, more than it has ever supplied in the wake of disaster. The recipients range from volunteer fire stations to trailer parks to an art collective in West Asheville.

Mike Talyad, a photographer who last year launched the collective to support artists of color, teamed up with the Grassroots Aid Partnership, a national nonprofit, to fill in relief gaps in the wake of Helene. “The whole city was trying to figure it out,” he said. 

Solar panels from Footprint that initially powered a water filter have now largely displaced the generators for the team’s food trucks, which last week were providing 1,000 meals a day. “When we did the switchover,” Talyad said, “it was a time when gas was still questionable.”

Last week, the team at Footprint also provided six solar panels, a Tesla battery, and charging station to displace a noisy generator at a retirement community in South Asheville.

The device was powering a system that sucked water from a pond, filtered it, and rendered it potable. Picking up their jugs of drinking water, a steady flow of residents oohed and aahed as the solar panels were installed, and sighed in relief when the din of the generator abated. 

“Most responders are not playing with solar microgrids because they’re better for the environment,” said Heegaard. “They’re playing with it because if they can turn their generator off for 12 hours a day, that means literally half the fuel savings. Some of them are spending tens of thousands of dollars a month on diesel or gas. That is game changing for a response.” 

‘Showing up for their neighbors’

Footprint’s robust relief effort and the variety of its beneficiaries is owed in part to the scale of Helene’s destruction, with more than 1 million in North Carolina alone who initially lost power.  

“It’s really hard to put into words what’s happening out there right now,” said Matt Abele, the executive director of the North Carolina Sustainable Energy Association, who visited in the early days after the storm. “It is just the most heartbreaking thing I’ve ever seen — whole mobile home parks that are just completely gone.” 

But the breadth of the response is also owed to Footprint’s approach to aid, which is rooted in connections to grassroots groups, government organizations, and the local solar industry. All have partnered together for the relief effort. 

“We’ve been incredibly overwhelmed by the positive response that we’ve seen from the clean energy community,” Abele said, “both from an equipment donation standpoint and a financial resources standpoint.” 

Some four hours east of the devastation in Western North Carolina, Greentech Renewables Raleigh has been soliciting and storing solar panels and other goods. It’s also raising money for products that are harder to get for free — like PV wire and batteries. Then it trucks the supplies west.

“We’ve got bodies, we’ve got trucks, we’ve got relationships,” said Shasten Jolley, the manager at the company, which warehouses and sells supplies to a variety of installers. “So, we try to utilize all those things to help out.”

The cargo is delivered to Mars Hill, a tiny college town about 20 miles north of Asheville that was virtually untouched by Helene. Through a local regional government organization, Frank Johnson, the owner of a robotics company, volunteered his 110,000-square-foot facility for storage.

Johnson is just one example of how people in the region have leapt to help each other, said Abele, who’s based in Raleigh.

“You can tell when you’re out there,” he said, “that so many people in the community are coping by showing up for their neighbors.”

‘Available for the next response’

To be sure, Footprint’s operations aren’t seamless at every turn. For instance, most of the donated solar panels designated for the South Asheville retirement community didn’t work, a fact the installers learned once they’d made the 40-minute drive in the morning and tried to connect them to the system. They returned later that afternoon with functioning units, but then faced the challenge of what to do with the broken ones.

“This is solar aid waste,” Heegaard said. “The last site we did yesterday had the same problem. Now we have to figure out how to recycle them.”

It’s also not uncommon for the microgrids to stop working, Heegaard said, because of understandable operator errors, like running them all night to provide heat.  

But above all, the problem for Footprint is scale. A tiny organization among behemoth relief groups, they simply don’t have the bandwidth for a larger response. When Milton followed immediately on the heels of Helene, Heegaard’s group made the difficult choice to hunker down in North Carolina. 

With climate-fueled weather disasters poised to increase, the organization hopes to entice the biggest, most well-resourced players in disaster relief to start regularly using solar microgrids in their efforts. 

As power is slowly restored across the region, with just over 5,000 remaining without electricity, there’s also the question of what comes next.

While there’s a parallel conversation underway among advocates and policymakers about making microgrids and distributed solar a more permanent feature of the grid, Footprint also hopes to inspire some of that change from the ground up. Maybe the volunteer fire station decides to put solar panels on its roof when it rebuilds, for instance. 

“We can change the conversation around resilience and recovery by directly pointing to something that worked when the lights were out and debris was in the street,” Heegaard said.

As for the actual Footprint equipment, the dream is to create “lending libraries” in places like Asheville, to be cycled in and out of community events and disaster relief.

“The solar trailer or the microgrid or the water maker that went to the Burnsville elementary school right after the storm – that can be recycled and used to power the music stage or the movie in the park,” Heegaard said. “Then that equipment is here, it’s being utilized, and it’s available for the next response, whether it’s in Knoxville or Atlanta or South Carolina.”

Last year, Michigan got attention as the first Midwestern state to adopt an energy storage standard. Energy storage is essential for the clean energy transition because it allows clean electricity initially generated by sources like wind and solar to be available at all times.

The standard calls for 2,500 MW of energy storage to be deployed by 2030. This storage will be fulfilled by a range of technologies, with lithium-ion batteries, the type of the storage that has grown rapidly across the U.S. and the world in recent years, chief among them. But it’s not too early to start thinking about how this standard (and future standards) will also involve new technologies that serve different needs, including shifting low-cost energy over longer periods of time to support electric reliability and affordability. A U.S. Department of Energy report found that to achieve a net-zero economy, the U.S. grid may need 225 GW to 460 GW of long-duration energy storage by 2050. By comparison, the U.S. currently has over 500 GW of gas power plants, and battery storage capacity is expected to double to about 30 GW by the end of this year, according to the U.S. Energy Information Administration.

Fortunately, Michigan’s energy legislation anticipated this need. The legislation that created the 2030 storage target also ordered Michigan regulators to report to lawmakers on the potential for long-duration and multi-day energy storage. The Michigan Public Service Commission (MPSC) is in the midst of this study right now.

But how is “long-duration” energy storage different from the battery storage that is growing quickly in Michigan and across the country right now? It’s all about the concept of duration, which refers to how long a storage resource like a battery can discharge stored energy until it is out of capacity. Most of the batteries being built at utility scale right now have a duration of around four hours. But long-duration storage refers to resources that have a duration of over 8 hours and up to well over 100 hours.

This longer duration unlocks capabilities that will make 100% clean electricity a reality. Short-duration storage right now can cover shortfalls in wind and solar on an hour-by-hour basis. But what about if there is a shortfall in energy supply expected not for just a few hours, but from one day to the next? Or from one month to the next? Those situations arise especially in seasons like winter, where cloud cover can linger and hamper solar energy production for extended periods of time. That is where the need for long-duration storage comes in. Long-duration storage could become a capacity resource that grid operators can tap to reliably deal with long-term fluctuations in energy supply, like those caused by changes in the season from summer to winter.

What would this type of energy storage actually look like in practice? Two companies that are members of the Michigan Energy Innovation Business Council are potential examples.

• Energy Dome’s above ground compressed gas technology, the “CO2 Battery,” is a closed-loop system that holds carbon dioxide gas in a large dome structure. Using electricity from solar panels and wind turbines, this gas is heated and compressed into a liquid, which can be easily stored at room temperature. When discharging, the liquid is evaporated, and the resulting gas spins a turbine, generating electricity when needed, often with one full cycle per day (8+ hours of discharging). The company is currently constructing its first full-scale plant in Sardinia, Italy, with the project nearing completion. In the U.S., another plant is soon to follow, with project proponent Alliant Energy recently filing for regulatory approval of the Columbia Energy Storage Project in Wisconsin.
• Form Energy is commercializing a multi-day energy storage technology, a 100-hour duration iron-air battery for utility-scale applications. Essentially, the battery rusts and un-rusts iron to store and release electricity. Form Energy has constructed a new factory to manufacture these batteries domestically, and is working to deploy the first large-scale demonstrations of its technology with utilities like Great River Energy, Xcel Energy, Dominion and Georgia Power in 2025 and 2026.

A tremendous amount of innovative work will need to happen between now and the realization of the full potential for long-duration storage. There are a few things Michigan regulators should do with their study to best set up the state to reap the benefits from these emerging technologies:

First, the Commission should set clear targets for how much long-duration and multi-day storage utilities need to procure in coming years. Utilities are generally conservative and hesitant to pursue new technologies unless pushed or clearly allowed. But this problem is particularly heightened when it comes to long-duration storage. That’s because utilities, if given a megawatt target for storage they must deploy, will likely acquire storage without considering the benefits of having a diverse portfolio of technologies that can deliver energy over different durations. As a result, Michigan may lose out on the operational benefits that come from having a diversified storage portfolio. These benefits include the ability of long-duration storage to make firing up high-emitting, fossil-fuel-burning peaker plants unnecessary because the storage can provide more reliable, cleaner and cheaper alternatives. They also include overall cost and land-use savings, by storing renewable energy when it would otherwise be wasted and shifting it over long time periods when it is most needed.

Second, speaking of substitutes for fossil fuel plants, the Commission should identify which power plant sites around the state could be good candidates for being replaced with long-duration storage projects. Michigan’s coal-fired power plants are almost all retired, with Consumers Energy this year set to retire its final coal plant in Ottawa County. Long-duration storage could be fitting replacements for not only those plants, but also gas plants that will be reaching the end of their life cycles in coming years.

With its storage targets, Michigan has already become one of the national leaders in energy storage. Let’s further cement that reputation by taking steps now for smart planning for long-duration storage. All Michiganders stand to benefit from the potential for long-duration storage to enable an electric grid that is cleaner, lower-cost and more reliable.

California policymakers are searching for ways to rein in the cost of expanding the state’s power grid, which is necessary to combat climate change. Experts warn they’re missing an opportunity that’s right in front of them — taking advantage of the growing number of clean energy technologies owned by utility customers.

California ended its legislative session last month unable to pass a proposed legislative package to address rising electricity rates for customers of Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric, which serve about three-quarters of the state’s residents.

Lawmakers also failed to pass several bills aimed at boosting the role battery-backed rooftop solar systems, electric vehicles, and electric heat pumps and water heaters can play in balancing the power that’s available on the grid.

Replacing fossil-fueled vehicles with EVs, and gas heating systems with heat pumps, will increase statewide electricity demand, requiring utilities to invest billions of dollars to upgrade their grids. But those same technologies can shift when they use power to avoid the handful of hours per year when demand spikes. That’s important, because the cost of building power grids is largely determined by the size of those spikes — and in turn is a core driver of California’s energy affordability crisis.

If the state can use distributed energy resources to shave a bit of demand from grid peaks, it stands to save big. One example: In an April report, consultancy Brattle Group projected that virtual power plants, which can shift when EVs and electric appliances draw from the grid or tap into customer solar and battery systems, could provide more than 15 percent of the state’s peak grid demand by 2035. That would amount to around $550 million per year in consumer savings. 

About $500 million of that would flow directly to the customers who own the devices, which could help defray the cost of buying EVs and heat pumps, two technologies that need to be rapidly adopted to meet climate goals. But because tapping into those devices would cost less than making large-scale investments, utilities — and by extension all of their customers — would save about $50 million per year by 2035, Brattle found.

“California’s affordability challenges are years in the making and are worsened by climate-driven impacts like heat waves and wildfires,” said Edson Perez, who leads trade group Advanced Energy United’s legislative and political engagement in California. ​“However, there are critical steps we can take now: optimizing our existing grid, maximizing the cost-effectiveness of essential grid upgrades, and fully leveraging available technologies like distributed energy resources.”

But as it stands, California isn’t putting the full weight of policy support behind these types of distributed energy programs.

Pilot programs have petered out, seen their budgets clawed back, or have been outright canceled. The scale of demand-side resources operating in the state has actually declined over the past decade, even as the state’s grid stresses have increased. And efforts to create statewide targets for distributed energy — like those that helped spur California’s rooftop-solar and home-battery leadership — have failed to gain traction, including a proposed bill in the state’s just-concluded legislative session.

Advocates say it’s time for the state to change that — especially since there’s an expiration date for capturing the value of DERs. Without policies to encourage utilities and customers to work together to realize the grid benefits of these technologies, utilities will simply build expensive, centralized infrastructure to meet rising electricity demand. Once that money is spent, potential savings can’t be realized, undermining the economic case for VPPs.

Unfortunately, utilities have clear incentives to discount the potential of VPPs as a money-saving tool, because they earn guaranteed rates of profit on capital investments like grid buildouts, but don’t for alternatives like VPPs. Plus, they’re held responsible for failing to keep pace with growing power demand — and are loath to rely on decentralized assets owned by customers in place of tried-and-true grid investments.

California’s VPP policy landscape

This utility reluctance may well explain why a roster of bills aimed at enlisting DERs to combat rising grid costs stalled in this year’s regular legislative session.

SB 1305 proposed requiring the California Public Utilities Commission to determine targets for utilities to ​“procure generation from cost-effective virtual power plants,” and then mandate that the utilities meet them.

Similar targets for rooftop solar and batteries have been valuable for boosting early-stage deployments in California, said Cliff Staton, head of government affairs and community relations at Renew Home, the company formed by the merger of Google Nest’s smart-thermostat energy-shifting service Nest Renew and California-based residential demand-response aggregator Ohmconnect.

“If you set the targets, you begin to provide the certainty to the industry that if you invest, there will be a return for your investment over time,” Staton said.

An early version of SB 1305 set hard percentage targets for VPP procurements by 2028 and by 2035. Those percentages were stripped from the bill later in the session, leaving the final targets up to CPUC discretion. The bill failed to clear a key legislative committee anyway.

Another bill that died in committee, AB 2891, would have expanded options for VPPs to capture the value of the peak load reductions they can provide. The legislation would have ordered the California Energy Commission to create methods for VPPs to reduce how much generation capacity each utility in the state must secure to meet peak grid demands in future years.

Only a handful of California’s community choice aggregators — the public entities that supply power to an increasing number of customers of the state’s major utilities — are using this approach today. But those CCAs have been able to start paying customers with solar and batteries for the value they can provide by reducing reliance on increasingly expensive contracts with centralized grid resources — mostly fossil-gas-fired power plants.

For more than a decade, state laws have called on the CPUC to create programs that reward customers for the energy and grid values provided by their solar panels, backup batteries, electric vehicles, and remote-controllable devices like smart thermostats and water heaters.

But these efforts have been plagued by an on-again, off-again approach from regulators and utilities. The California Energy Commission set a goal in 2023 of achieving 7 gigawatts of load flexibility from VPPs and other customer-owned resources by 2030; two of the CEC’s key contributions to that effort saw their budgets slashed this year.

Meanwhile, many of the programs launched by the CPUC over the past decade have stalled out due to overly complicated structures, or had their budgets reduced or canceled due to concerns over their cost-effectiveness.

The CPUC and the California Independent System Operator (CAISO), the entity responsible for managing California’s transmission grid and energy markets, argue that these programs have failed to perform as promised. Relying on them more would run the risk of eroding rather than improving grid reliability, they say.

But the companies engaging in these VPP programs — smart-thermostat providers like Renew Home and ecobee; solar and battery installers like sonnen, Sunrun, Sunnova, and Tesla; and demand-response providers like AutoGrid, CPower, Enel X, and Voltus — argue that overly complex and restrictive rules and compensation structures are to blame.

Adding to these challenges for would-be VPP providers is the declining value of rooftop solar. Major changes in California’s net-metering policies over the past two years have slashed the value of customer-owned solar systems, slowing the growth of the state’s leading rooftop solar market.

That’s a problem for VPP providers and advocates who see rooftop solar as an important way to help meet demand from households and businesses with EVs and heat pumps — and to charge up batteries with clean electricity that VPP programs can tap into later.

A host of bills were proposed to reset state policy to restore more value to customer-owned solar during this year’s legislative session. But only one — SB 1374, which restores compensation for schools that install solar — made it through.

California’s new rooftop solar regime does reward customers for adding batteries to store surplus solar power during the day and discharge it in evenings, when the grid faces its greatest and most costly stresses.

But solar and battery advocacy groups argue that those rewards haven’t counterbalanced the broader erosion of rooftop solar values — and that the VPP opportunities that have emerged in the state can’t yet be trusted to make up the remaining difference.

“It’s important for customers to find value in the investment they’ve made, and to help the grid and lower cost for all consumers,” said Meghan Nutting, executive vice president of government and regulatory affairs at Sunnova. ​“One of the problems with VPP programs so far is that it’s really tough to talk about that value proposition up front because programs are so short, you can’t count on them, or the funding isn’t there.”

Why grid costs and VPPs are intertwined 

At the same time, California policies that encourage people to buy other distributed energy resources — namely EVs and heat pumps — are under threat from rising electricity rates, which are eroding the benefits of switching from fossil fuels.

A controversial policy enacted this year to reduce the per-kilowatt-hour rates paid by customers of the state’s big three utilities in exchange for higher fixed costs may or may not ease that pressure. But both opponents and supporters of the policy agree that shifting the balance of fixed and variable electricity costs does little to address the underlying problems.

Programs that enlist those exact same distributed energy resources to ease grid stresses have a much clearer value proposition, on the other hand.

About half of the electricity bills of customers of California’s three big utilities is made up of fixed costs like grid investments. A majority of those investments are tied to building a grid robust enough to supply power not just for average needs, but during the few hours per year when electricity use peaks.

Those peaks are getting bigger as California’s climate goals encourage more EVs and heat pumps to come online, and the costs of dealing with that have only just begun to be built into utilities’ broader grid investment plans. A series of studies ordered by the CPUC found that adding demand from EVs and heat pumps to the grid could increase ratepayer costs by more than $50 billion by 2035 — or, depending on the approach taken, costs could be contained to less than half of that over the same timespan.

One key variable in those distinct cost forecasts is whether EVs can be programmed or incentivized to avoid charging all at once and overwhelming the grid. ​“Smart charging” programs that encourage EV owners to shift when they charge their cars could save California ratepayers tens of billions of dollars over the coming decade.

With the right policies and technologies in place, big new grid demands like EVs could actually become valuable resources for energy in their own right. SB 59, a bill that passed in this year’s legislative session after failing to make it last year, orders state agencies to study the proper role for regulation that could require automakers to enable their EVs to support ​“vehicle-to-grid” charging — sending power from EV batteries back to homes, buildings, or the grid at large.

The challenge for utilities and regulators is finding the right mix of approaches that can allow them to take advantage of EVs, heat pumps, residential solar and batteries, and other distributed resources such that they avoid either overbuilding or underbuilding the grid, said Merrian Borgeson, policy director for California climate and energy at the environmental nonprofit Natural Resources Defense Council.

“We have to be really careful with any new investment — but we do need to make new investments,” she said. ​“If we pull back too far on energizing loads like electric homes or EV trucks, we miss out on getting those loads connected.”

Climate anxiety affects nearly half of young people aged 16-25. Students like second-year Rachel Mohammed find hope and inspiration through her involvement in innovative climate solutions, working alongside peers who share her determination. “I’ve met so many people at MIT who are dedicated to finding climate solutions in ways that I had never imagined, dreamed of, or heard of. That is what keeps me going, and I’m doing my part,” she says.

Hydrogen-fueled engines

Hydrogen offers the potential for zero or near-zero emissions, with the ability to reduce greenhouse gases and pollution by 29 percent. However, the hydrogen industry faces many challenges related to storage solutions and costs.

Mohammed leads the hydrogen team on MIT’s Electric Vehicle Team (EVT), which is dedicated to harnessing hydrogen power to build a cleaner, more sustainable future. EVT is one of several student-led build teams at the Edgerton Center focused on innovative climate solutions. Since its founding in 1992, the Edgerton Center has been a hub for MIT students to bring their ideas to life.

Hydrogen is mostly used in large vehicles like trucks and planes because it requires a lot of storage space. EVT is building their second iteration of a motorcycle based on what Mohammed calls a “goofy hypothesis” that you can use hydrogen to power a small vehicle. The team employs a hydrogen fuel cell system, which generates electricity by combining hydrogen with oxygen. However, the technology faces challenges, particularly in storage, which EVT is tackling with innovative designs for smaller vehicles.

Presenting at the 2024 World Hydrogen Summit reaffirmed Mohammed’s confidence in this project. “I often encounter skepticism, with people saying it’s not practical. Seeing others actively working on similar initiatives made me realize that we can do it too,” Mohammed says.

The team’s first successful track test last October allowed them to evaluate the real-world performance of their hydrogen-powered motorcycle, marking a crucial step in proving the feasibility and efficiency of their design.

MIT’s Sustainable Engine Team (SET), founded by junior Charles Yong, uses the combustion method to generate energy with hydrogen. This is a promising technology route for high-power-density applications, like aviation, but Yong believes it hasn’t received enough attention. Yong explains, “In the hydrogen power industry, startups choose fuel cell routes instead of combustion because gas turbine industry giants are 50 years ahead. However, these giants are moving very slowly toward hydrogen due to its not-yet-fully-developed infrastructure. Working under the Edgerton Center allows us to take risks and explore advanced tech directions to demonstrate that hydrogen combustion can be readily available.”

Both EVT and SET are publishing their research and providing detailed instructions for anyone interested in replicating their results.

A major expansion of battery storage may be the most economical and environmentally beneficial way for Illinois to maintain grid reliability as it phases out fossil fuel generation, a new study finds.

The analysis was commissioned by the nonprofit Clean Grid Alliance and solar organizations as state lawmakers consider proposed incentives for private developers to build battery storage.

“The outlook is not great for bringing on major amounts of new capacity to replace the retiring capacity,” said Mark Pruitt, former head of the Illinois Power Agency and author of the study, which suggests batteries will be a more realistic path forward than a massive buildout of new generation and transmission infrastructure. 

The proposed legislation — SB 3959 and HB 5856 — would require the Illinois Power Agency to procure energy storage capacity for deployment by utilities ComEd and Ameren. Payments would be based on the difference between energy market prices and the costs of charging batteries off-peak, to ensure the storage would be profitable. The need for incentives would theoretically ratchet down over time. 

“As market prices for power go up, your incentive goes down,” Pruit said. “The idea is to provide an incentive that bridges the gap between the cost of battery technology and the value in the market. Over time, those will equalize and level out.” 

The bills, introduced in May at the end of the legislature’s spring session, would amend existing energy law to add energy storage incentives to state policy, along with existing incentives for nuclear and renewables. 

The study noted that Illinois will need at least 8,500 new megawatts of capacity and possibly as much as 15,000 new megawatts between 2030 and 2049, with increased demand driven in part by the growth of data centers. Twenty-five data centers being proposed in Illinois would use as much energy as the state’s five nuclear plants generate, according to nuclear plant owner Exelon’s CEO Calvin Butler Jr., quoted by Bloomberg. 

The North American Electric Reliability Corporation (NERC) found in its summer and winter 2024 assessments that within MISO and PJM regional grids, Wisconsin, Michigan, Minnesota, Illinois and Indiana are all at “elevated” risk of insufficient capacity. 

“NERC, PJM, MISO and the Illinois Commerce Commission have all identified the potential for capacity shortfalls,” said Pruitt. “You do have some options for alleviating that. You can build transmission and bring in capacity from outside the state. You can maintain your current domestic generating capacity [without retiring fossil fuel plants]. You could expand your domestic generating capacity. And an independent variable is your growth rate. All these have to work together, there’s no silver bullet. We know there are major challenges on each of those fronts.” 

Gloomy numbers 

The latest PJM capacity auction results showed capacity prices increasing from $28.92/MW-Day for the 2024/25 period to $269.92/MW-Day — a nearly 10-fold increase — for the following year. That “translates into an annual cost increase of about $350 for a typical single-family household served by ComEd,” Pruitt said. “The increase in costs indicates that more capacity supply is required to meet capacity demand in the future.” 

There are many new generation projects in the queue for interconnection by MISO and PJM, but many of them drop out before ever being deployed because of unviable economics, long delays, regulatory challenges and other issues. A recent study by Lawrence Berkeley National Laboratory noted that while interconnection requests for renewables have skyrocketed since the Inflation Reduction Act, only 15% of interconnected capacity was actually completed in PJM and MISO between 2000 and 2018, and experts say similar completion rates persist. 

“This finding indicates that deploying sufficient new capacity resources to offset [fossil fuel] retirements is not likely to occur in the near term,” said Pruitt. “Just because something is planned doesn’t mean it gets built.” 

Meanwhile the state is running out of funds for the purchase of renewable energy credits (RECs) that are crucial to driving wind and solar development. The 2024 long-term renewable resources procurement plan by the IPA shows the state’s fund for renewables reaching a deficit in 2028, so that spending on RECs from renewables will have to be scaled back by as much as 60%. 

Long-distance transmission lines could bring wind energy or other electricity from out of state. But planned transmission lines have faced hurdles. The Grain Belt Express transmission line, in the works for a decade, was in August denied needed approval from an Illinois appellate court. The transmission line, proposed by Invenergy, would have brought wind power from Kansas to load centers to the east. 

“That sets it back years,” Pruitt said. “Transmission is a very long-term solution. I’m sure people are working diligently on it, but it’s five to 10 years before you get something approved and built.” 

Value proposition, solar benefits 

Pruitt’s study found that if 8,500 MW of energy storage were deployed between 2030 and 2049, Illinois customers could see up to $3 billion in savings compared to if they had to foot the bill for increased capacity without new storage. The savings would come because of lower market prices in capacity auctions, as well as investment in new transmission and generation that would be avoided. 

Pruitt found that $11 billion to $28 billion in macro-level economic benefits could also result, with blackouts avoided, reduced fossil fuel emissions and jobs and economic stimulus created. 

Pruitt’s analysis indicates that the incentives proposed in the legislation would cost $6.4 billion to customers. But the storage would result in $9.4 billion in savings compared to the status quo, hence a $3 billion overall savings between 2030 and 2049. 

“Solar is great, but solar is an intermittent resource; battery storage when paired with solar allows it to be far more reliable,” said Andrew Linhares, Central Region senior manager for the Solar Energy Industry Association. “Battery storage is not as cheap as solar, but its reliability is its hallmark. Combining the resources gives you a cheap and reliable resource.” 

“Solar and storage is this powerful tool that can help reduce costs for consumers and create new jobs and economic activity,” he continued. “I don’t believe that same picture is there for building out new natural gas resources. Anything that helps storage, helps solar and vice versa. CEJA sees these two technologies as being joined at the hip for the future, they are being seen more and more as a single resource.”

When Yakama Nation leaders learned in 2017 of a plan to tunnel through some of their ancestral land for a green energy development, they were caught off guard.

While the tribal nation had come out in favor of climate-friendly projects, this one appeared poised to damage Pushpum, a privately owned ridgeline overlooking the Columbia River in Washington. The nation holds treaty rights to gather traditional foods there, and tribal officials knew they had to stop the project.

Problems arose when the Federal Energy Regulatory Commission, the agency in charge of permitting hydro energy projects, offered the Yakama Nation what tribal leaders considered an impossible choice: disclose confidential ceremonial, archaeological and cultural knowledge, or waive the right to consult on whether and how the site is developed.

This put the Yakama Nation in a bind. Disclosing exactly what made the land sacred risked revealing to outsiders what they treasured most about it. In the past, disclosure of information about everything from food to archaeological sites enabled non-Natives to loot or otherwise desecrate the land.

Even now, tribal leaders struggle to safely express what the Pushpum project threatens. “I don’t know how in-depth I can go,” said Elaine Harvey, a tribal member and former environmental coordinator for the tribal fisheries department, when asked about the foods and medicines that grow on the land.

“It provides for us,” echoed Yakama Nation Councilmember Jeremy Takala. “Sometimes we do get really protective.”

Although government agencies have sometimes taken significant steps to protect tribal confidentiality, that didn’t happen with the Pushpum proposal, known as the Goldendale Energy Storage Project. Tribal leaders repeatedly objected, telling the agency that if a tribal nation deems a place sacred, they shouldn’t have to break confidentiality to prove it — a position supported by state agency leaders and, new reporting shows, at least one other federal agency.

Nonetheless, after seven years, in February FERC moved the project forward without consulting with the Yakama Nation.

The process known as consultation is often fraught. Federal laws and agency rules require that tribes be able to weigh in on decisions that affect their treaty lands. But in practice, consultation procedures sometimes force tribes to reveal information that makes them more vulnerable, without offering any guaranteed benefit.

The risks of disclosure are not hypothetical: Looting and vandalism are common when information about Indigenous resources becomes public. One important mid-Columbia petroglyph, called Tsagaglalal, or She Who Watches, had to be removed from its original site because of vandalism. And recreational and commercial pickers have flooded one of Washington’s best huckleberry picking areas, called Indian Heaven Wilderness, pushing out Native families trying to stock up for the winter.

The Yakama Nation feared similar outcomes if it fully participated in FERC’s consultation process over the Goldendale development. But there are alternatives. The United Nations recognizes Indigenous peoples’ right to affirmatively consent to development on their sacred lands. A similar model was included in state legislation in Washington three years ago, but Gov. Jay Inslee vetoed it.

The requirements of the consultation process are poorly defined, and state and federal agencies interpret them in a broad range of ways. In the case of Pushpum, critics say that has allowed FERC to overlook tribal concerns.

“They’re just being totally disregarded,” said Simone Anter, an attorney at the environmental nonprofit Columbia Riverkeeper and a descendant of the Pascua Yaqui and Jicarilla Apache nations. “What FERC is doing is so blatantly, blatantly wrong.”

The Yakama Nation has been outspoken in its support for renewable energy development, including solar and small-scale hydro projects. But not at Pushpum; it’s sacred to the Kah-milt-pah people, one of the bands within the Yakama Nation, who still regularly use the site.

The proposal would transform this area into a facility intended to store renewable energy in a low-carbon way. Rye Development, a Florida-based company, submitted an application for permits for a “pumped hydro” system, where a pair of reservoirs connected by a tunnel store energy for future use.

FERC has offered few accommodations for the Yakama Nation on the Goldendale project.

FERC spokesperson Celeste Miller told High Country News and ProPublica in an email that “we will work to address the effects of proposed projects on Tribal rights and resources to the greatest extent we can, consistent with federal law and regulations. This is a pending matter before the Commission, so we cannot discuss the merits of this proceeding.”

“FERC legally doesn’t have to do very much here,” said Kevin Washburn, a dean of the University of Iowa College of Law, a citizen of the Chickasaw Nation of Oklahoma and a former assistant secretary of Indian affairs at the Department of the Interior. “Consultation is designed to open the door so tribes can get in the door to talk to decision-makers.” According to experts, the process can range from collaborative planning that addresses tribal concerns to a perfunctory discussion with minimal impacts, depending on the agency.

“This is the problem with consultation and its lack of teeth,” said Anter. “If the federal government is saying, ‘Hey, we consulted, check that box,’ who’s to say they didn’t?”

There’s another problem with consultation, too: Any discussions with a federal entity are subject to public disclosure. That’s good for government transparency, Washburn said, but it can make tribal nations even more vulnerable. “And it’s why tribes are right to be cautious in what they share with feds,” he said.

That’s an obstacle at Pushpum. Things became even harder there in August 2021, when FERC notified the Yakama Nation that federal consultation would be carried out not by the agency itself, but by the developer. The Yakama Nation pushed back, asserting its treaty rights to negotiate as a sovereign nation only with another nation, not with a private entity. FERC, however, insisted that designating a third party was “standard practice.” The National Historic Preservation Act, signed into law in 1966, says an agency “may authorize an applicant or group of applicants to initiate consultation,” but maintains that the federal agency is still “responsible for their government to government relationships with Indian tribes.”

The Yakama Nation also worried about commission rules that require anything the tribal nation says to FERC be shared with the developer. “It gets very sensitive when we share those kinds of stories,” said Takala, the tribal councilmember. “We just don’t share to anyone, especially a developer.”

Some say FERC could change that internal rule, since it isn’t required by law. “For them to cite their own regulations and be like, ‘Our hands are tied,’ is ridiculous,” Anter said. For months, FERC and the Yakama Nation went back and forth over the conditions under which the tribal government would share sensitive information, with the Yakama Nation repeatedly asking to share information only with FERC.

Ultimately, FERC proposed four ways the Yakama Nation could participate in consultation. In the eyes of tribal leaders, all these options either posed significant risks to the privacy of their information or rendered consultation meaningless.

The first three were laid out in a letter from Vince Yearick, director of FERC’s division of hydropower licensing, sent on Dec. 9, 2021. For option one, it suggested the tribal nation request nondisclosure agreements from anyone accessing sensitive information. Yearick did not specify whether FERC would be responsible for issuing or enforcing these NDAs.

Delano Saluskin, then-chair of the Yakama Nation, called this option “far from the requirements of NHPA or in line with the trust responsibility that the Federal Agency has to Yakama Nation,” citing FERC policies and National Historic Preservation Act law in a February 2022 letter to state and federal government officials requesting support. He added that it “describes a process that does not protect information that is sacred and sensitive from disclosure.”

Alternatively, FERC said, the Yakama Nation could simply redact any sensitive information from documents it filed. This option, however, would leave FERC in the dark about the details of what cultural resources the project would imperil. That would make it harder for FERC to require project adjustments or weigh the specific impacts in its decision about whether to permit construction.

Third, the Yakama Nation could withhold sensitive information altogether, which would present similar problems.

Lastly, in a June 2022 follow-up letter, the commission suggested that the Yakama Nation submit a document “with more details regarding the resources of concern” and a request that some of the information be treated as privileged or withheld from public disclosure.

Overall, Saluskin described FERC’s options as a “failure” to conduct legal consultation in good faith.

A federal agency similarly raised concerns: In May 2023, the Advisory Council on Historic Preservation, which advises the president and the Congress on protecting historic properties across the country, wrote to FERC suggesting that it “provide the Tribes with opportunities to share information that will be kept confidential.” FERC’s rule regarding disclosure, the council said, could insulate the agency from meaningful consultation, “and as a result from any real understanding of the nature and significance of properties of religious and cultural significance for Tribes.”

The concerns over FERC’s engagement with the Yakama Nation are part of a wider discussion of whether and how the U.S. government should protect tribal privacy and cultural resources. Speaking at a tribal energy summit in Tacoma in June 2023, Allyson Brooks, Washington’s state historic preservation officer, said that even though the consent language was vetoed by the governor, state law for protecting confidentiality around tribal cultural properties is still stronger than federal law, which only protects confidentiality if a site is eligible for the National Register of Historic Places.

In Washington, if a tribal historic preservation officer says, “‘X marks the spot; this is sacred,’ we say, ‘OK,’” Brooks declared. She said asking tribal nations to prove a site’s sacredness is like asking to see a photo of baby Jesus before accepting the sanctity of Christmas. “You don’t. You say ‘nice tree’ and take it at face value. When tribes say ‘X is sacred,’ you should take that at face value too.”

That approach is vital to the Yakama Nation, which recently saw a developer involved with a project proposed in nearby Benton County leak information that the nation believed was private.

The Horse Heaven Hills wind farm would be the biggest energy development of any kind in Washington state history. But the sprawling 72,000-acre project overlaps with nesting habitat for migratory ferruginous hawks, a raptor state-listed as endangered.

Court documents related to the permitting proceedings show that the Yakama Nation believed it had identified the locations of the ferruginous hawks’ nests as confidential, in part because the hawks are ceremonially important. In May 2023, the Yakama Nation requested a protective order from the Energy Facility Site Evaluation Council, a state-level analog of FERC. The order, which the council issued, instructed all parties to sign a confidentiality agreement before accessing confidential information, similar to the nondisclosure agreements FERC proposed. If any party disclosed that information, they could be liable for damages.

But the order didn’t stop that information from getting out. In February 2024, the Seattle Times published a story on the Horse Heaven Hills wind farm, which included a map of ferruginous hawk nests — a map that was credited to Scout Clean Energy, the developer.

The Yakama Nation quickly filed a motion to enforce the protective order, alleging that Scout Clean Energy had transgressed by passing protected cultural information to the press.

The developer counter-filed, claiming that even if nest locations were a part of confidentiality discussion, the map itself was not, and that it was so imprecise that the critical details remained confidential. The council ultimately agreed.

Despite the risks, Washburn said that tribes should take any opportunity to share their stories with federal officials, even if the conditions aren’t perfect. “I wouldn’t necessarily encourage tribes to give their deepest, darkest secrets to a federal agency,” he said. “But I would encourage them to meet with FERC and try to give FERC a first-person account of why they think this is important.”

Not all experts agree. Brett Lee Shelton, a member of the Oglala Sioux Tribe and an attorney at the Native American Rights Fund, said FERC is out of step with other federal and state agencies. “It’s hard to believe that it’s anything but disingenuous, using that tactic,” he said. “It’s pretty well known by any agency officials who deal with Indian tribes that sometimes certain specifics about sacred places need to remain confidential.”

And for Bronsco Jim, a spiritual leader of the Kah-milt-pah people, sharing too many details is out of the question. Cultural specifics stay within the oral teachings of the longhouse, the site of the Kah-milt-pah spiritual community. Jim said he doesn’t even know how to translate all of the information into English. “We don’t write it, you won’t see it posted. You won’t see it in books. It’s our oral history. It’s sacred.”
