Materials related to Longer-Term Transmission Studies (LTTSs) in New England will be posted below. These materials will include NESCOE study requests, study scopes, presentations, reports, responses to written stakeholder comments, and any necessary modeling information. Initiated in response to the New England State’s Energy Vision, the 2050 Transmission Study is the first Longer-Term Transmission Study.
NESCOE-requested transmission studies performed to identify high-level concepts of transmission infrastructure that could meet a New England state’s energy policy, mandate, or legal requirement based on state-identified scenarios and timeframes, which may extend beyond the five-to-ten year planning horizon.
