NYISO, PJM, and ISO New England interregional committee releases 2017 Northeast Coordinated System Plan

No new needs identified for interregional transmission projects

The interconnections between neighboring electric power systems allow for the exchange of electric energy and capacity, facilitating access to a wider diversity of resources and the more economic trading of energy. Identifying the need for interregional transmission projects and regional system reinforcements, quantifying their possible benefits and other impacts, and resolving planning issues with potential cross-border effects can enhance the reliability and efficiency of the power system overall. The New York Independent System Operator (NYISO), ISO New England (ISO-NE), and PJM (i.e., the Regional Transmission Organization [RTO] for all or parts of 13 eastern and Midwestern states and the District of Columbia) work collaboratively to coordinate the planning of their interconnected systems. On April 24, 2018, the ISO/RTOs released the 2017 Northeast Coordinated System Plan (NCSP17), which summarizes the group’s 2016 and 2017 interregional planning efforts.

ISO-NE successfully completes FERC audit of competitive transmission planning process, financial requirements, and more

On April 18, 2018, ISO New England received a successful audit report from the Federal Energy Regulatory Commission (FERC) Division of Audits and Accounting (DAA). The audit evaluated the ISO’s compliance during the period of July 10, 2013, through June 30, 2017, with the ISO Open Access Transmission Tariff; FERC Order No. 1000, which established new electric transmission planning and cost allocation requirements; and FERC’s accounting, reporting, and record-retention requirements. The DAA found no incidents of noncompliance.

Regional transmission investment: Spring 2018 update

768 projects put into service since 2002 to fortify New England’s transmission system

The ISO recently published the March 2018 update to the Regional System Plan (RSP) Project List, which details Pool Transmission Facility (PTF) projects needed to ensure reliability in New England. Since the October 2017 update, 22 upgrades were placed in service and no new projects were added. Since 2002, a cumulative total of 768 project components representing an investment of $10.4 billion have been placed into service to help ensure that New England’s transmission system continues to reliably and efficiently move wholesale electricity across the region.

ISO-NE publishes 2018 Regional Electricity Outlook 

ISO New England has published its 2018 Regional Electricity Outlook (REO), an annual report looking at the trends and challenges affecting New England’s power system, as well as the innovative solutions the ISO is pursuing to ensure reliable electricity for the region’s homes and businesses—today and into the future. The report describes changes to the region’s electric grid over the past two decades, and how the ISO is working to keep New England on the cutting edge as the region’s electricity industry rapidly evolves towards a future of renewable and natural gas resources.

The 2018 REO, as well as webpages that highlight and expand on information and statistics in the report, are available at www.iso-ne.com/reo.


ISO-NE, NEPOOL, and PTO AC make joint filing regarding the interconnection clustering methodology 

Update 11/1/2017: FERC has issued its order accepting the interconnection queue clustering revisions. FERC rejected all protests and determined that the clustering revisions increase efficiencies, better inform the decisions of project developers, and allow project developers to share the costs of the upgrades necessary to accommodate their interconnection. By allowing interconnection requests to be studied in a cluster, the clustering revisions should provide a means to relieve the queue backlog in northern and western Maine, which is one of the primary obstacles to interconnections in that region.

Get easy access to helpful ISO-NE maps and diagrams on new webpage

ISO New England is pleased to announce the Maps and Diagrams webpage: a new one-stop-shop for many of the ISO’s most commonly used maps and diagrams related to the electric power system, the wholesale electricity marketplace, system planning, and industry relationships. The page is also a jumping off point to other informative pages across the ISO’s expansive website. The new page can be found under the About Us tab in the Key Grid and Market Stats section.
