Flatiron executives describe ChalkPoint storage project and expected role in PJM capacity markets
Summary
Flatiron Energy witnesses told the Public Service Commission that the ChalkPoint Reliability Storage project will reuse existing Chalk Point interconnection infrastructure, participate in PJM capacity auctions, and receive fixed ESCC payments intended to support development while refunding capacity revenues to Maryland ratepayers.
Colin Scofield, vice president of origination at Flatiron Energy, told the Public Service Commission that he helped prepare ChalkPoint’s application and pricing and that the company will operate the project as a capacity resource in PJM. "I reviewed the request for application that came out in December 2025, identified Chalk Point, project as a potential applicant, and then helped prepare, both the narrative response and the project pricing," Scofield said on the record.
Scofield and other Flatiron witnesses said the project would participate in PJM capacity auctions and that Maryland ratepayers would be refunded any PJM capacity market revenues the project earns, with fixed ESCC payments used to support project economics. "ChalkPoint will be reusing some of the existing interconnection infrastructure from the ChalkPoint generating station," Scofield added, saying reuse should ease interconnection at lower cost.
Joel Harrington, who leads government and regulatory affairs for Flatiron’s storage portfolio, and Charles McGovern, director of development, were presented as company witnesses and confirmed their previously filed direct and rebuttal testimony. Company witnesses repeatedly emphasized that the project’s purpose within the Maryland solicitation is to add incremental supply to the PJM market and that awarding multiple projects can reduce program attrition and increase the likelihood that storage capacity will be developed.
