Battery Storage for Fossil-Fueled Peaker Power Plant Replacement: A Maine Case Study

Across the country, more than a thousand fossil fuel burning peaker power plants sit idle, waiting to be called upon by electricity grid operators. These plants are designed to fire up quickly in response to regional demand spikes. While this serves a critical need, fossil-fueled peaker plants are highly polluting and expensive, and are disproportionately sited in low-income communities, communities of color, and areas already overburdened by pollution.

A new analysis, conducted by Strategen for the Clean Energy States Alliance (CESA), demonstrates that batteries can cost effectively replace aging fossil-fueled peakers. The analysis is focused on Maine, where the Governor’s Energy Office is currently engaged in designing a 200-MW energy storage procurement process. But the results, which are largely based on regional energy capacity market revenue opportunities, are applicable throughout New England, and should help to inform peaker replacement initiatives in other regions as well. The report, “Battery Storage for Fossil-Fueled Peaker Plant Replacement: A Maine Case Study,” is available here:

In this CESA webinar, report author Eliasid Animas from Strategen will discuss the methodology and findings of the analysis. He will be joined by contributing editor Todd Olinsky-Paul from CESA. Following the presentation, they will address questions from the audience.

This report and webinar were generously supported with funding from the Barr Foundation and from the Maine Community Foundation—Seal Bay II Fund.
