Suggested adjustments to energy prices would allow for efficiency through interconnection clustering. ISO New England, New England Power Pool Participants Committee and the Participating Transmission Owners Administrative Committee filed proposed tariff changes to incorporate a new clustering methodology in the ISO’s interconnection procedures. Suggested adjustments to energy prices would allow for efficiency through interconnection clustering. The proposed methodology would allow two or more interconnection requests to be analyzed in the same System Impact Study and for developers to share costs for certain interconnection-related transmission upgrades. The filing parties propose to first implement the clustering methodology to help move forward the backlog of interconnection requests experienced in northern and western Maine, where more than 5,800 megawatts of proposed new resources, mostly wind, are seeking to interconnect to the regional grid. FERC has issued its order accepting the interconnection queue clustering revisions.
