Access documents related to the Extended-Term Transmission Planning Tariff Changes Key Project.
The ISO is proposing changes to Attachment K of the Open Access Transmission Tariff to incorporate a process that will allow requests by the New England States Committee on Electricity (NESCOE) for the ISO to perform system planning analyses that identify, at a high-level, transmission infrastructure necessary to meet a New England state’s energy policy, mandate, or legal requirement. Subsequent Tariff changes will be proposed to incorporate study outcomes and allocation of transmission system modification costs into the process. This project was initiated in response to the New England State’s Energy Vision.
NESCOE study requests, study scopes, presentations, reports, responses to written stakeholder comments, and any necessary modeling information for these studies will be posted on the Longer-Term Transmission Studies (LTTSs) webpage. This includes documentation for the 2050 Transmission Study, which is the first LTTS requested by NESCOE.
The Extended-Term Transmission Planning Tariff Changes project is just one of several key projects at the ISO, which continuously undertakes a variety of short- and long-term projects to enhance the region's competitive wholesale electricity markets and ensure reliable operation of the power grid.
