ISO-NE expects sufficient power supplies this summer

New England is expected to have sufficient resources to meet peak consumer demand for electricity this summer under both typical and extreme weather conditions.

ISO New England prepares short-term forecasts for the summer and winter seasons, taking into account estimated contributions from all resources, including those with and without an obligation through the capacity market to supply electricity; unplanned resource outages; imports from neighboring regions; and resource additions and retirements. These estimates help inform ISO New England’s planning on how to operate the grid during the upcoming peak season.

Earth Day 2019: A capacity market first

Every year, ISO New England fields requests from new resources seeking to enter the Forward Capacity Market. And every year, ISO analysts research those resources to ensure they’ll be able to provide the region with the capacity they’re promising three years in the future. But what happens when a resource is actually 5,000 individual power systems spread out across four New England states?

Finalized capacity auction results confirm FCA #13 procured sufficient resources, at a lower price, for 2022–2023

Finalized results from the 13th Forward Capacity Auction (FCA #13) confirm that the auction concluded with sufficient resources to meet electricity demand in 2022–2023, at the lowest price in six years. The auction was the first run under the Competitive Auctions with Sponsored Policy Resources (CASPR) rules, which include a substitution auction where resources interested in retiring can trade their capacity supply obligation to new state-sponsored resources that didn’t clear in the primary auction. 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 2022-2023 

New England’s annual capacity auction for power system resources concluded Monday with sufficient resources to meet peak demand in 2022-2023, and preliminary results indicate the clearing price was the lowest in six years. The auction is run by ISO New England Inc. to procure the resources that will be needed to meet consumer demand for electricity in three years.

The auction was the first run under the Competitive Auctions with Sponsored Policy Resources (CASPR) rules, which include a secondary substitution auction where resources interested in retiring can trade their capacity supply obligation to new state-sponsored resources that didn’t clear in the primary auction.

Capacity vs energy: a primer

Next week, ISO New England will run the 13th Forward Capacity Auction to secure the power system resources needed to meet peak demand in 2022-2023. The auction is run annually to ensure the region has the necessary resource capacity three years into the future. But what is capacity, and how does it differ from the energy markets the ISO runs on a day-ahead and real-time basis? ISO New England has put together a primer on these two measurements of energy, and how the two types of markets play into running the New England power system.

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).
