Electricity demand is on the rise in Maine. Should nuclear power be a part of the energy mix?

The remains of the Maine Yankee nuclear plant in Wiscasset are protected by a tall chain link fence topped with razor wire and a checkpoint manned by armed guards.

About a quarter of New England’s electricity comes from nuclear reactors in New Hampshire and Connecticut.

But Jamie Dickerson, senior director of climate and clean energy programs at the Acadia Center, doubts nuclear will make significant inroads in the region.

“Most of the modeling that we have reviewed largely suggests a future where solar, wind and batteries are really dominating the generating resource mix well into the future,” Dickerson said.

Even as New England states see prospects to rapidly build out offshore wind resources in the face of market forces and political obstruction, Dickerson still thinks nuclear will complement, not displace, renewable generation.

Massachusetts could give heat pump owners a huge discount on electricity

Massachusetts regulators are considering a plan to make heat pumps an obvious financial choice for most residents.

The state Department of Public Utilities is mulling a proposal to heavily discount electricity rates in the winter months for households with heat pumps, a move that could cut energy bills for more than 80% of residents who switch over to the efficient, electric appliance from fossil-fueled or electric resistance heating. For many of those households, the savings would amount to hundreds or even thousands of dollars each winter.

Supporters of seasonal heat pump rates stress that the lower prices do not mean that heat pump users are being subsidized by everyone else. In fact, they say, the proposed rate structure is far more fair than the status quo.

“This is not a handout to heat pump owners,” said Kyle Murray, director of state program implementation for clean-energy nonprofit Acadia Center. ​“This is a fundamental issue of fairness.”

Here’s why: The delivery portion of an electricity bill pays for the construction and upkeep of the poles, wires, and other infrastructure needed to get power where it’s going. To determine how much to charge customers — and this is a bit of a simplification — the utility divides the total cost by the number of kilowatt-hours it expects customers to use. That number becomes the delivery rate.

Report: Adopting heat pumps in Mass. is an issue of fairness

SPRINGFIELD — There’s a way for Massachusetts residents to reduce the costs of electricity while the state works to achieve its climate goals: widespread adoption of air-source heat pumps.

 That’s according to a new report from Switchbox, a New York climate policy think tank.

The fund was one of a few organizations that commissioned Switchbox’s report. The others include Green Energy Consumers Alliance in Boston; Acadia Center in Hartford, Connecticut; ZeroCarbonMA, a statewide coalition; and Rewiring America, a national group.

“They actually aren’t incurring any more stress upon the grid or the system than than their non-heat pump counterparts,” said Kyle Murray, state program implementation director at Acadia Center in Connecticut. Despite this, heat pump customers are charged more than double for the delivery of electricity, the report said.

Murray, of Acadia Center, said ratepayers should only be charged for the amount of energy they incur.

“This is a fundamental issue of fairness at the end of the day,” he said.

New Report: Massachusetts households poised for more than $600 in median savings with heat pump upgrades under proposed rates

BOSTON – A new report shows that 82% of MA households can save an average of $687 each winter by upgrading to high-efficiency heat pumps if the Massachusetts Department of Public Utilities (DPU) adopts proposed rate changes from the Massachusetts Department of Energy Resources (DOER). The findings show that the proposed rates would help correct an existing imbalance in which current heat pump users are unfairly subsidizing other electric ratepayers.

The report, Heat Pump Rates in Massachusetts, was developed by Switchbox and sponsored by Environmental Defense Fund, Acadia Center, Rewiring America, Green Energy Consumers Alliance, and ZeroCarbonMA. The analysis highlights how Under DOER’s proposed rates, most electric customers of National Grid, Eversource, and Unitil would save money by switching to heat pumps, including single-family homeowners and customers who heat with methane gas.

“This report makes clear that fairer electric rates are key to unlocking the full potential of clean heating,” said Kyle Murray, Director, State Program Implementation and Massachusetts Program Director for Acadia Center. “The proposed heat pump rates level the playing field, correcting outdated price structures and delivering real savings for households. This isn’t just about savings for individual households, smarter rates strengthen the grid, support a cleaner economy and move us closer to our climate goals.”

Report Details Cost Savings of Heat Pump Rates for Mass. Consumers

Strong winter discounts on electricity delivery rates are needed to more fairly charge Massachusetts homes with heat pumps for their share of grid costs, according to a new report commissioned by a coalition of environmental groups.

In December, an interagency working group recommended that the DPU require the utilities to establish more aggressive winter heat pump discounts. (See Mass. Electricity Rates Working Group Issues Recommendations.) 

Under this updated discount, houses with heat pumps would pay roughly the same delivery costs as those heated by gas during the heating season. Supply costs would not be affected by the discount, and heat pumps would still pay for their full supply costs throughout the year. 

Kyle Murray, director of state program implementation at the Acadia Center, emphasized that heat pump rates do not represent a “handout to heat pump owners.” 

“Even though heat pump owners are using more energy than their non-heat pump counterparts, they’re not actually causing more stress on the system,” Murray said. “Heat pump rates just simply represent fairness in ratemaking.”

Renewables Helped Prevent Blackouts on New England’s Hottest Day This Summer

Renewable energy sources, such as solar power and battery storage, have helped keep power on in New England, even during peak demand on the hottest day of summer.

According to a recent report from the nonprofit Acadia Center, more than 5 gigawatts of behind-the-meter solar provided additional support during peak demand times, despite the temperature in New England exceeding 100 degrees Fahrenheit on June 24.

ISO New England, a grid operator, issued a Power Caution on June 24 due to the heat, and that evening, peak energy demand reached 26,024 MWh, the highest peak since 2013.

Based on Acadia Center’s findings, as much as 22% of power usage in New England on June 24 came from behind-the-meter solar.

Thanks to residential solar, customers did not have to face energy blackouts and even saved money on skyrocketing electricity prices during the heat wave. The report from Acadia Center noted that while wholesale electricity prices reached more than $1,000 per megawatt-hour (MWh), customers with behind-the-meter solar saved more than $8.2 million collectively. This estimate may even be much lower than reality, with Acadia Center explaining that behind-the-meter solar may have saved customers $19.4 million in energy costs on June 24 alone.

“Solar was helping not just deliver megawatt-hours but also suppressing demand for the entire region,” Jamie Dickerson, senior director of clean energy and climate programs at Acadia Center, said in a statement. “Basically helping ensure that the grid could keep the lights on, could keep the air conditioning running.”

But total energy and cost savings were likely even higher thanks to other clean energy improvements, such as battery storage and higher energy efficiency. According to Acadia Center, energy efficiency helped reduce peak demand by about 2 gigawatts.

As Canary Media reported, extensive battery storage in Vermont further reduced grid strain during peak demand. Green Mountain Power, a utility provider in Vermont, was able to reduce strain on the grid via residential and EV batteries, saving customers around $3 million.

“Green Mountain Power has proven that by making these upfront investments in batteries, you can save ratepayers money,” Peter Sterling, executive director of the trade association Renewable Energy Vermont, told Canary Media. ​“It’s something I think is replicable by other utilities in the country.”

Acadia Center warned that recent cuts to the Inflation Reduction Act for clean energy investments will likely limit states’ and utility providers’ abilities to quickly, efficiently respond in similar peak energy demand scenarios, which would increase risk of power disruptions to consumers.

“Those resources are susceptible to equipment failure and to outages, and there is correlated outage risk across the very large fleet of natural gas generation in the region,” Dickerson said. “All the more reason why we need to diversify the region’s portfolio.”

Relying solely on fossil fuel energy sources alone will not be enough to meet demand, especially during heat waves like the one observed in New England on June 24.

“Taken together, the June 24 heat wave event was a clear example of a successful portfolio-based approach, using multiple complementary clean energy resources — solar, energy efficiency, energy storage, transmission imports, and beyond — to help ensure resource adequacy for the grid and relieve extreme prices for the region’s consumers,” the Acadia Center report concluded. “Unless further thwarted by counterproductive federal proposals, the northeast will see an increasingly diversified clean energy portfolio called upon to meet similar peak demand events in the years ahead, minimizing the reliance on aging, inefficient fossil fuel power plants to serve peak demand.”

How Trump’s big law impacts Massachusetts

The massive tax and domestic policy bill passed by Congressional Republicans and signed by President Trump this month expands tax cuts, limits Medicaid and food assistance programs, balloons immigration enforcement spending, and adds trillions to the national debt.

The WBUR newsroom took a look at how some key provisions may affect residents and programs in Massachusetts.

“The [Big Beautiful Bill] is bad, bad, bad for Massachusetts. Bad for ratepayers’ wallets, bad for grid reliability, bad for energy independence,” wrote Kyle Murray, Massachusetts program director at the Acadia Center, a climate advocacy and research group, in an email. “It will be a setback for the clean energy industry and will force Massachusetts to adopt new creative strategies to keep vital public policy goals on track.”

Batteries are playing a bigger role in keeping the lights on during New England heat waves

Battery storage and small-scale solar played a critical role in keeping New England’s electric grid reliable and may have saved customers tens of millions of dollars during late June’s major heat wave, according to a new analysis.

As temperatures soared above 100 degrees Fahrenheit and the region saw thick humidity, people cranked their air conditioners, drawing more power from the grid.

That shift could have saved consumers more than $19 million, according to an analysis by the Acadia Center, a regional environmental nonprofit and thinktank.

Absent all that rooftop solar, Acadia Center estimates New England would have broken its 19-year record for peak demand.

Power banking

The Acadia Center and ISO New England say power storage also played a critical role in keeping the lights on during this heat wave.

“I think people are really starting to understand that the value of renewables increases substantially when you pair them with batteries,” said Noah Berman, with the Acadia Group.

Batteries — whether smaller ones in people’s homes, or bigger “utility scale” ones plugged into the regional transmission grid — store power when it’s cheap and plentiful, like solar energy in the middle of the day.

Analysts with the Acadia Center hope batteries and a little extra coordination on the part of grid operators and utilities could help make that future winter peak lower, saving money and carbon emissions.

Behind-the-meter Solar Shines in ISO-NE Capacity Deficiency Event

ISO-NE’s capacity deficiency event demonstrated the significant benefits of solar resources, along with their limits in displacing fossil resources during peak load periods.

Amid the rapid growth of behind-the-meter (BTM) solar in New England, a capacity deficiency event demonstrated the significant benefits of solar resources, along with their limits in displacing fossil resources during peak load periods.

Without the contributions of BTM solar, ISO-NE estimates the peak would have reached over 28,400 MW at about 3:40 p.m. The 2,400-MW reduction in the region’s peak provided significant cost and reliability benefits to the grid. According to an analysis by the Acadia Center, “BTM solar avoided as much as roughly $19.4 million in costs on this single day by suppressing the overall price of wholesale electricity.

In the wake of the capacity deficiency event, clean energy advocates made the case that increased energy storage capacity would have provided significant benefits during the peak.

“Had we had even more behind-the-meter solar paired with storage online, we could have potentially completely avoided that absurd price spike later in the evening,” said Kyle Murray of the Acadia Center at the June 25 hearing.

The Acadia Center wrote in its analysis of the event that there is “clear evidence that additional BTM battery energy storage would have been able to further reduce the overall cost to consumers by increasing flexibility and shifting the solar production later in the day, dampening the early evening peak prices.”

A heat wave hit New England’s grid. Clean energy saved the day.

As temperatures across New England soared above 100 degrees Fahrenheit in recent weeks, solar panels and batteries helped keep air conditioners running while reducing fossil-fuel generation and likely saving consumers more than $20 million.

“Local solar, energy efficiency, and other clean energy resources helped make the power grid more reliable and more affordable for consumers,” said Jamie Dickerson, senior director of clean energy and climate programs at the Acadia Center, a regional nonprofit that analyzed clean energy’s financial benefits during the recent heat wave.

At the same time, rooftop and other ​“behind-the-meter” solar panels throughout the region, plus Vermont’s network of thousands of batteries, supplied several gigawatts of needed power, reducing demand on an already-strained system and saving customers millions of dollars. It was a demonstration, supporters say, of the way clean energy and battery storage can make the grid less carbon-intensive and more resilient, adaptable, and affordable as climate change drives increased extreme weather events.

“As we see more extremes, the region still will need to pursue an even more robust and diverse fleet of clean energy resources,” Dickerson said. ​“The power grid was not built for climate change.”

On June 24, behind-the-meter solar made up as much as 22% of the power being used in New England at any given time, according to the Acadia Center. At 3:40 p.m., total demand peaked at 28.5 GW, of which 4.4 GW was met by solar installed by homeowners, businesses, and other institutions.

As wholesale power prices surpassed $1,000 per megawatt-hour, this avoided consumption from the grid saved consumers at least $8.2 million, according to the Acadia Center.

This estimate, however, is conservative, Dickerson said. He and his colleagues also did a more rigorous analysis accounting for the fact that solar suppresses wholesale energy prices by reducing overall demand on the system. By these calculations, the true savings for consumers actually topped $19 million, and even that seems low, Dickerson said.
