Available below are information and materials related to ISO New England’s request for proposals (RFP) process for finding competitive solutions to identified transmission needs in the region. These needs may relate to power system reliability, efficiency of wholesale electricity markets, or public policy goals. Learn more about the ISO’s responsibilities in identifying transmission needs, running the RFP process, and allocating costs.
Also see the Planning Advisory Committee (PAC) page, Market Efficiency Transmission, Public Policy Transmission, and Key Study Areas for materials related to the study and identification of system needs and the evaluation of proposals submitted for the RFPs below.
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.
As they are issued, RFPs will be listed below for Market Efficiency Transmission Upgrades (METUs) and Public Policy Transmission Upgrades (PPTUs), as well as eligible Reliability Transmission Upgrades (RTUs), in the region. The problem statement and requirements document for each RFP will include timelines and other details.
Note: An RFP may be cancelled by the ISO at any time if, for example, system needs change.
View the Prior Year List of Projects Designated to the PTOs—a list of transmission projects for which Participating Transmission Owners (PTOs) were designated as the entity responsible for construction and ownership, following the performance of solutions studies, per Section 4.1(j)(iii) of Attachment K of the Open Access Transmission Tariff.
