2018 transmission-outage coordination stats and goals

ISO-NE had requests for almost 3,500 planned outages and handled over 800 unplanned outages last year

No one wants a power line to stop working unexpectedly, like during a major storm. But power lines and other transmission equipment must undergo some down time so that participating transmission owners (PTOs) can conduct routine maintenance for avoiding emergencies, accommodate new construction, or address problems that crop up. One of the ISO’s responsibilities is to analyze impacts of and schedule these outages all over New England with the PTOs and local control centers (LCCs) so that the PTOs do not remove their equipment from service at the same time or when an outage will negatively affect some other ongoing activity. The long-term scheduling of transmission outages is critical because it gives the ISO the time to measure both the reliability and economic impacts of proposed outages to the system and communicate the probable effects to market participants, which helps keep the energy markets operating efficiently.

The ISO New England Transmission Equipment Outage Coordination 2018 report summarizes the outage process that took place in 2018, the number and types of outages that occurred, and the 2019 goals for the ISO’s Outage-Coordination group for improving outage coordination, reducing congestion costs, and increasing operational flexibility.

Regional transmission investment: Spring 2019 update

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

The ISO recently published the March 2019 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 2018 update, 10 upgrades were placed in service, and no new projects were added. Since 2002, a cumulative total of 797 project components representing an investment of $10.9 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 2019 Regional Electricity Outlook 

ISO New England has published its 2019 Regional Electricity Outlook (REO), an annual report looking at the trends affecting New England’s power system and the innovative solutions the ISO is pursuing to ensure reliable electricity for the region’s homes and businesses—today and into the future. New England’s traditional power grid is rapidly becoming a hybrid system where electricity needs will be met by conventional resources and significant amounts of large-scale renewable resources connected to the regional transmission system, in combination with thousands of small resources connected directly to retail customers or local distribution utilities. The report describes how the ISO is working to solve the operational and market challenges that emerge during this major transformation. The 2019 REO is available at www.iso-ne.com/reo.

Regional transmission investment: Fall 2018 update

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

The ISO recently published the October 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 June 2018 update, 12 upgrades were placed in service, two new projects were added, and the cost estimate of one major reliability project decreased $29.8 million. Since 2002, a cumulative total of 787 project components representing an investment of $10.7 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.

Eastern Interconnection Planning Collaborative completes report on the state of the Eastern Interconnection

The Eastern Interconnection Planning Collaborative (EIPC) has issued a report on the State of the Eastern Interconnection, the collection of power systems serving two-thirds of the US and Canada. The report describes the extensive coordinated planning undertaken by the collaborative’s 20 major transmission Planning Coordinators since 2009 to maintain the reliability of the bulk power grid throughout the Eastern Interconnection. Read the press release.

Regional transmission investment: Summer 2018 update

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

The ISO recently published the June 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 March 2018 update, 7 upgrades were placed in service and no new projects were added. Since 2002, a cumulative total of 775 project components representing an investment of $10.56 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.
