What is the Greater Boston and New Hampshire Solution?


National Grid and Eversource, long-standing and committed community partners, are teaming up to deliver a set of critical reliability projects in the Greater Boston and southern New Hampshire area. Our Solution comprises various projects, each with individual merit, which together address the reliability problems identified by ISO-NE (see below), improve the region’s power system, and meet the customer demand for power for years to come.
