FERC accepts capacity requirements for 2022/2023

The Federal Energy Regulatory Commission (FERC) has accepted ISO New England’s proposed Installed Capacity Requirement (ICR) value of 34,719 megawatts (MW) to be used in the 13th Forward Capacity Market auction (FCA #13), which commences February 4, 2019. The ICR is the amount of capacity (generation, demand-side resources, and imports) the ISO has determined needs to be available in 2022/2023 to meet the region’s projected consumer demand. The ICR value is calculated using reliability requirements based on the probability of disconnecting load due to a resource deficiency (also referred to as Loss of Load Expectation or LOLE) no more than once every 10 years (1-in-10).

2018/2019 winter outlook: New England expected to have adequate resources 

ISO New England has implemented near-term changes based on lessons learned from historic cold snap

ISO New England, operator of New England’s power system, expects the region to have the necessary resources this winter to meet consumer demand, which is expected to peak at 20,357 megawatts (MW) under normal weather conditions or 21,057 MW at extreme temperatures.

However, as seen during last year’s two-week cold snap, power system operations could become challenging if demand is higher than projected, if the region loses a large generator, electricity imports are affected, or during periods of fuel delivery constraints. In those instances, the ISO could be required to implement emergency operating procedures to maintain reliability.

Summer 2018 outlook: adequate electricity supplies expected

Under normal weather conditions, New England is expected to have sufficient resources to meet peak consumer demand for electricity this summer, according to ISO New England. Tight supply margins could develop if forecasted peak system conditions associated with extreme hot and humid weather occur. If this happens, ISO New England will take steps to manage New England’s electricity supply and demand and maintain power system reliability. View the press release.

Finalized capacity auction results confirm FCA #12 procured sufficient resources, at a lower price, for 2021–2022

Finalized results from the 12th Forward Capacity Auction (FCA #12) confirm that the auction, conducted on February 5 and 6, concluded with sufficient resources to meet electricity demand in 2021–2022, at the lowest price in five years. While the auction closed with enough resources to meet demand, the ISO rejected two bids from resources looking to withdraw from the capacity market for the one-year capacity commitment period. The ISO’s mandatory transmission reliability review showed that transmission lines in Greater Boston could be overloaded if the resources, Mystic 7 and Mystic 8, were not available during 2021-2022. ISO New England filed the results with the Federal Energy Regulatory Commission (FERC) on February 28. The FERC filing includes a list of resources that have an obligation to be available in that capacity commitment period. Read the press release.

ISO-NE forward capacity auction closes with adequate power system resources for 2021-2022

The ISO will retain about 1,300 megawatts to ensure local reliability

New England’s annual Forward Capacity Market auction for power system resources concluded Tuesday, February 6 with sufficient resources to meet peak demand in 2021-2022, and preliminary results indicate the clearing price was the lowest in five years due to a surplus of capacity in the region. The auction is run by ISO New England to procure the resources that will be needed to meet consumer demand for electricity in three years.

The 12th Forward Capacity Auction closed at a preliminary clearing price of $4.63 per kilowatt-month (kW-month) across New England, compared to $5.30/kW-month in last year’s auction. The auction concluded with commitments from 34,828 MW to be available in 2021-2022, a number that includes 1,103 MW of surplus capacity system-wide and about 1,300 MW of resources that were retained for transmissions security after they sought to delist. The auction rules allow the region to acquire more or less than the capacity target, providing flexibility to acquire additional capacity and enhanced reliability at a cost-effective price.

FERC accepts capacity requirements for 2021/2022

The Federal Energy Regulatory Commission (FERC) has accepted ISO New England’s proposed Installed Capacity Requirement (ICR) value of 33,725 megawatts (MW) to be used in the 12th Forward Capacity Market auction (FCA #12), which commences February 5, 2018. The ICR is the amount of capacity (generation, demand-side resources, and imports) the ISO has determined needs to be available in 2021/2022 to meet the region’s projected peak demand, plus required reserves. The ICR value is calculated using reliability requirements based on the probability of disconnecting load due to a resource deficiency (also referred to as Loss of Load Expectation or LOLE) no more than once every 10 years (1-in-10).
