Access materials related to key studies of the transmission system in the city of Boston, Massachusetts, and surrounding area.
Key study areas are specific portions of New England’s transmission system, subdivided for practical work management reasons, or for focus on a particular technical issue. The ISO regularly conducts studies in key areas pursuant to the Open Access Transmission Tariff (Section II of the ISO Tariff). The assessments and studies involve stakeholder review and input, primarily by the Planning Advisory Committee, and form the foundation for the Regional System Plan.
The ISO restricts access to all ISO and stakeholder-submitted materials marked as "Critical Energy Infrastructure Information." Some materials in this section contain CEII, and your browser cannot access them without the ISO’s prior approval. If you are not a market participant and wish to access this material, you will need to complete and submit a CEII Access Request Form and receive the ISO’s approval. If you are a market participant and wish to access this material, contact your organization’s security administrator (SA) for the ISO’s Customer and Asset Management System (CAMS). Your SA must enter your name into the CAMS database and assign you the necessary roles and permissions. For further information, see the Request CEII Access page.
