Dive Brief:
- Declaring an emergency in parts of the PJM Interconnection’s footprint, the U.S. Department of Energy on Friday ordered Constellation Energy and PJM to continue operating 760 MW of oil- and gas-fired peaking capacity in Pennsylvania that Constellation had planned to deactivate the next day.
- The emergency order directs Constellation to keep operating two units at its Eddystone power plant near Philadelphia until Aug. 28. The order can be extended.
- PJM supports DOE’s order. “The department’s order is a prudent, term-limited step that will retain the covered generators for a 90-day period,” the grid operator said Saturday. “This will allow DOE, Constellation Energy and PJM to undertake further analysis regarding the longer-term need and viability of these generators.”
Dive Insight:
The Federal Power Act’s section 202(c) gives the DOE secretary the authority to temporarily order power plants to operate during wars and emergencies. It has been used 17 times since August 2020, according to DOE.
DOE partly based its order on a May 9 report from PJM that said the grid operator had enough power supplies for this summer under normal conditions, but that under extreme conditions featuring record-setting demand it could have to call on demand response resources to avoid power outages.
In determining that PJM faces an emergency, DOE also cited a PJM report from February 2023 indicating the grid operator faced tightening supply-demand conditions this decade. In addition, PJM in December asked FERC to approve a fast-track interconnection process for some planned power supplies to address potential reliability concerns, DOE said. FERC approved the plan in February.
“The potential shortage of electric energy, shortage of facilities for the generation of electric energy, and other causes in the region support the need for the Eddystone Units to contribute to system reliability,” DOE said.
DOE issued a similar emergency order on May 23 to keep a 1,560-MW, coal-fired power plant owned by Consumers Energy in Michigan running for nearly three months beyond its planned retirement date.
Constellation is taking immediate steps to continue to operate Eddystone units 3 and 4 through the summer, according to Paul Adams, a spokesman for the Baltimore-based independent power producer.
“Eddystone Units 3 and 4 remain in ‘Ready’ status and we are working quickly to retain necessary staff and perform necessary maintenance to allow for safe and reliable operations this summer and beyond,” Adams said Monday in an email.
Like in other regions, power plant owners in PJM must get permission from the grid operator to retire a generating unit. PJM studies whether a power plant shutdown will hurt grid reliability. PJM approved Constellation’s request to shutter its Eddystone units 3 and 4 in February 2024, saying retiring the units didn’t pose reliability risks. The units were installed between 1967 and 1970, according to Constellation.
PJM on Friday gave Buchanan Generation permission to deactivate on July 1 two gas-fired generating units in Virginia totaling 80 MW.
PJM operates the grid and wholesale power markets in 13 Mid-Atlantic and Midwest states and in the District of Columbia.
Depending on how long DOE ultimately orders the Eddystone power plant to keep running, the department’s order could affect Constellation’s plan to buy Calpine in a $16.4 billion deal. As part of its proposal pending at FERC, Constellation said it would sell four power plants totaling 3,546 MW in PJM’s eastern region, where Eddystone is located. The sale aims to allay concerns that a combined Constellation and Calpine could exert market power in eastern PJM.
Ratepayers will be required to pay for the costs of continuing to run the Eddystone units, including enough money to ensure Constellation earns a profit to maintain and run the units, Tyson Slocum, director of Public Citizen’s Energy Program, said in a press release.
“Trump’s last minute emergency order — issued literally on the last day these power plants were set to operate — causes significant, expensive complications,” Slocum said. “Old units like Eddystone require both minor and major maintenance — maintenance that was deferred because of its planned retirement on May 31.”
DOE’s “move to keep these zombie plants online will have significant public health impacts and increase electricity costs for people in Michigan and Pennsylvania,” Kit Kennedy, power sector managing director at the Natural Resources Defense Council, said Saturday.
Besides issuing additional emergency orders, DOE can extend previously issued orders under FPA section 202, ClearView Energy Partners said in a client note on May 30. “Weather predictions lie outside our remit, but we would suggest that a long, hot summer could set the stage for an extension,” the research firm said about the Consumers Energy order.
In its Constellation order, DOE noted that it is developing a methodology to identify current and anticipated reserve margins for all regions regulated by the Federal Energy Regulatory Commission. An April executive order requires the methodology to be published by July 7 and be used to establish a protocol to identify which generation resources are critical to system reliability and to prevent identified generation resources from leaving the bulkpower system, DOE said. The department plans to use the methodology to further evaluate Eddystone units 3 and 4.
