Slide 13: Overview
Overview DER applications in WMA continue to increase and bring more saturation to existing stations. Eversource continues to work closely with ISO-NE on DER projects to assess and verify the correct path forward for each project. Eversource substations are now seeing approximately 300MW of DER conn
Slide 14: Process Overview
Process Overview Developers can self-screen projects for likely anticipated path of study. Final determination can vary from below in some circumstances; important to review all points of the document. If your project is between 1MW & 5MW AND the interconnecting substation generation total is below
Slide 15: Hosting Capacity Maps
