CEG testified virtually and submitted written comments regarding the renewal of the Pittsfield Generating Company LP’s operating permit renewal by the Massachusetts Department of Environmental Protection.

Winter electric peaking capacity services are currently undervalued in the Massachusetts programs that provide battery customers with performance payments to supply power back to the grid at times of high demand.

CEG joined two dozen organizations in drafting and submitting a response to the New York Public Service Commission in opposition to a proposed “zero emissions” program that would make technologies like hydrogen combustion and renewable natural gas eligible under New York State’s Clean Energy Standard.

Solar Responders equips Puerto Rico’s fire stations with solar+storage to provide backup power and ensure effective communication and emergency services during natural disasters. This case study includes technical and financial details, as well as lessons learned over the course of the project.

This report assesses the design and performance of the Massachusetts ConnectedSolutions program, as it has been administered in the first three-year program cycle, and compares it with related programs in other states across the country.

These comments explain how the proposed Astoria Gas Plant replacement project proposed by NRG in New York City is inconsistent with New York’s Climate Leadership and Community Protection Act emissions reduction mandates. The comments were drafted in response to the issuance of a Draft Title V Air Permit and a Draft Environmental Impact Statement.

While hydrogen might have a valid role to play in deep decarbonization of the heavy transport or industrial sectors, runaway plans to use it extensively in the power sector have the potential to jeopardize the health of environmental justice communities, not to mention renewable energy goals.

This report explores energy storage policy best practices and lessons learned from the New England states. It aims to inform state policymakers and regulators seeking to expand energy storage markets.

This briefing paper assesses the viability of battery storage as a replacement for a proposed gas and oil peaker power plant in Peabody, Massachusetts. It examines the cost-effectiveness and public health implications of developing battery storage as an alternative solution to the proposed fossil-fuel power plant, known as Project 2015A.

Clean Energy Group submitted a response to DOE’s request for information regarding potential hydrogen demonstration and deployment projects, raising concerns about the recent wave of support for “clean” hydrogen development. The response details multiple critical issues that have not been adequately addressed in the rush to portray hydrogen as an emissions-free solution for the energy sector.
