Electrificación equitativa II: Resumen ejecutivo

A medida que Massachusetts avanza en la electrificación del sector del transporte y de los edificios, una estrategia clave para alcanzar los objetivos de descarbonización del estado, se prevé que la demanda pico de electricidad aumentará sustancialmente. Con el incremento de la demanda de electricidad, es probable que también aumente el costo de esta, poniendo…

Electrification with Equity, Part 2: Scaling Behind-The-Meter Solar+Storage in Massachusetts Environmental Justice Neighborhoods

Massachusetts has some of the best solar and energy storage programs in the country, but these programs lack meaningful equity provisions, and clean energy adoption rates in environmental justice communities are low. Solar and storage can provide many benefits that would be especially valuable to environmental justice communities, such as lowering energy costs, reducing local…

Electrification with Equity, Part 1: The Opportunity for Behind-the-Meter Solar and Storage in Massachusetts

To meet its emissions reduction targets and decarbonization goals, Massachusetts – like many states – is working towards the electrification of its building and transportation sectors. While this will help reduce air pollution, it will also increase the region’s electric demand, which could lead to a new round of investment in fossil fuel generation. This…

Decarbonizing the Peak: A Roadmap for Retiring and Replacing Massachusetts’ Fossil Fuel Peaker Plants by 2050

Massachusetts has committed to achieve net-zero emissions by 2050, a goal that requires retiring the state’s fossil fuel peaker power plants and replacing them with clean, reliable alternatives. This report by the Massachusetts Clean Peak Coalition, with analysis from Synapse Energy Economics, shows that net-zero technologies can meet the state’s peak electricity demand by 2050 while maintaining reliability and containing costs.

The High Cost of AI: How Data Centers Are Reshaping Pennsylvania’s Energy Landscape

This report details the impacts of rising energy demand from data centers in Pennsylvania and explains how the current trajectory will increase fossil fuel energy generation, raise energy costs, and worsen local air quality. The report includes recommendations for how community advocates and policymakers can push back against potentially harmful data center growth in their state. 

Location, Location, Location: An Economic Comparison of Large-Scale Batteries Installed in Front of vs. Behind the Meter in Massachusetts

This report compares the costs and benefits of one utility-scale, front-of-the-meter (FTM) battery system versus five commercial-scale, behind-the-meter (BTM) batteries of the same aggregate cost in Massachusetts. The report, commissioned by Clean Energy Group for the Cape and Vineyard Electric Cooperative (CVEC), provides useful information to help CVEC decide between two possible ownership models for…
