Eversource Investment Service Company LLC has submitted comments in response to Consolidated Edison Company of New York's proposal to develop a $1 billion Brooklyn Clean Energy Hub. The hub aims to interconnect a significant portion of New York's mandated offshore wind generation into the state's electrical grid. However, Eversource Investment Service Company LLC has raised several technical, cost, and regulatory concerns that need to be addressed before the project can proceed. These concerns include the limited design information, constructability, and potential system and market implications of the hub. Eversource Investment Service Company LLC also recommends that the Commission establish a framework for obtaining input from developers and other stakeholders in the technical feasibility assessment process.
