A report by Synapse Energy Economics for the Massachusetts Clean Peak Coalition suggests that Massachusetts can fully decarbonize peak generation by 2050 at a lower cost than continuing to run fossil-fuel peaker plants. The report recommends a portfolio of clean peaking resources including demand-side resources, energy storage, and wind generation. Challenges remain in fully decarbonizing the electricity system, particularly with the shift to a winter-peaking system and the current design of ISO New England's capacity market favoring fossil-fuel generators. The coalition is unsure if recent changes to the grid operator's capacity accreditation model will benefit decarbonization efforts in Massachusetts, but a peak generation portfolio combining wind, energy storage, and demand response could serve winter peaks at a lower cost than the current combustion-dominated generation mix. Regulators and policymakers need to focus on energy efficiency, longer-duration energy storage, addressing community concerns around wind siting, and considering climate and public health impacts to build this portfolio cost-effectively and explore alternatives to fossil peakers and combined heat and power plants.

Competition Is Heating Up In The US Energy Storage Space
Form Energy, a startup from Massachusetts, has developed an iron-air battery for long duration energy storage, surpassing Tesla's Megapack 3 in terms of duration. The company secured a 300-megawatt, 100-hour energy storage deal with Xcel Energy and Google, aiming to provide cost-effective, safe, and reliable energy storage solutions for a grid saturated with wind and solar power. Xcel Energy is moving forward with plans to deploy a Form iron-air battery in its energy plan for a new Google data center in Minnesota, pending approval from the Minnesota Public Utilities Commission. The technology involves iron pellets that rust when exposed to air, releasing energy, and can be recharged by applying electricity, with Form Energy receiving funding to establish a factory in West Virginia for mass production of their iron-air batteries.

Massachusetts can make ‘bottom-up’ distribution reforms for a better grid
Massachusetts is making strides in modernizing its electric grid and regulatory systems to meet decarbonization mandates and better serve customers. The state is exploring the DSO model to integrate distributed energy resources like solar, storage, heat pumps, and EVs, creating a more flexible and democratized energy system. The Grid Modernization Advisory Council is providing transparency and stakeholder input on utility planning, focusing on community needs and bottom-up planning. Stakeholders are advocating for a customer-driven, flexible grid, with the DSO model being recommended to enable grid edge flexibility and advance energy justice. Massachusetts utilities are recognizing the importance of a more flexible grid and modernized regulation, with the DSO structure seen as crucial in delivering an affordable, equitable, and efficient energy transition.

Massachusetts awards 1.3 GW in first large-scale energy storage tender
The Massachusetts DOER has chosen four energy storage projects, including Jupiter Power's Trimount ESS, to contribute to reaching a goal of 5,000 MW of operational storage capacity by 2030. Trimount ESS will be located at a former Exxon oil terminal in Everett, repurposing the site into a clean energy hub. This project is anticipated to defer $2.2 billion in regional transmission upgrades, showcasing the potential for large-scale energy storage to support the transition to renewable energy sources and reduce the need for costly infrastructure investments.

Solar and storage program forecast to save all Massachusetts ratepayers $313 million per year
A report from Synapse Energy Economics and the Solar Energy Industries Association highlights the potential benefits of solar plus storage in Massachusetts. By meeting deployment targets set by the SMART 3.0 incentive program, ratepayers could save $313 million per year by 2030. The program aims to push older, inefficient natural gas plants out of the auction, resulting in lower wholesale electricity prices. Solar and storage technologies can reduce the state's reliance on natural gas during winter months, leading to cost savings and emissions reductions. The planned expansion of solar and storage could avoid the use of 29 billion cubic feet of natural gas and reduce CO2 emissions by 1.6 million metric tons annually by 2030.

Ceres CEO and President Mindy Lubber testifies on Beacon Hill to support the creation of a climate bank in Massachusetts
Ceres CEO Mindy Lubber testified in support of legislation to create a climate bank in Massachusetts, which would leverage public and private investments to provide low-interest loans and financial products for climate mitigation and clean energy projects. The proposed bank follows a model used by 40 other state and local climate banks in the US, collectively investing $10.6 billion in clean energy projects in 2023. Lubber recommended prioritizing environmental justice communities for lending, in addition to rural and coastal communities, in order to combat climate change effectively.

How Will Boston And Other Coastal Cities Fight Sea Level Rise?
The Seaport District in Boston is facing increasing threats from sea level rise and flooding, with nearly all built structures at risk by 2050. Boston is collaborating with communities, nonprofits, government, scientists, and philanthropists through the Climate Ready Boston initiative to invest in coastal resilience projects. The city's Office of Climate Resilience is designing infrastructure to protect vulnerable areas like the Mario Umana Academy in East Boston. A proposed "Make Polluters Pay" bill in Massachusetts aims to hold major emitters accountable for climate damage costs, with bipartisan support for the idea of oil and gas companies paying into a superfund for climate adaptation projects. The increasing frequency of disasters is driving up costs for average people, leading to a belief that oil and gas companies should pay their fair share.

One Brownfield Down, One Clean Solar Power Plant Up
Solar power plants are being established as a quick and economical way to add kilowatts to the grid while also preserving farmland and transforming contaminated sites into community assets. The US Environmental Agency's Re-Powering America's Land program aims to harvest clean energy from contaminated sites, with brownfield-to-solar development becoming a mature sector of the solar industry. The Acton project in Massachusetts, utilizing ground screws for secure racking systems, showcases the industry's ability to transform contaminated sites into clean power stations. Terrasmart, a US racking firm, is manufacturing ground screws in-house to support the growth of the solar industry. The Acton project repurposes a contaminated Superfund site for solar energy production, creating local jobs and boosting grid resilience, with energy storage included to optimize the value of solar power for ratepayers. Community solar projects like Acton enable all ratepayers to save money as solar costs have dropped, driving significant growth in the community solar market and integrating with the agrivoltaic market. Despite challenges from the federal government, the demand for solar energy remains strong among ratepayers, with a new solar power plant in Acton, Massachusetts transforming a contaminated site into a community asset.
