Exelon Generation filed with the ISO New England to retire Mystic Generating Station’s Units 7, 8, 9, and the Jet unit on June 1, 2022.
Absent any regulatory reforms to properly value reliability and regional fuel security, these units will not participate in the forward capacity auction scheduled for February 2019.
ISO-NE recently stated that it may propose interim and long-term market rule changes to address system resiliency in light of reliability risks identified in ISO-NE’s January 2018 fuel security report. Changes to market rules are necessary because critical units to the region, like Mystic 8 and 9, cannot recover future operating costs including the cost of securing fuel. To the extent that changes are timely filed and approved by the Federal Energy Regulatory Commission, Exelon Generation may reconsider the retirement of the Mystic units.
In a related move, Exelon Generation also announced an agreement to purchase ENGIE North America’s LNG import terminal to ensure the continued reliable supply of fuel to Mystic Units 8 and 9 while they remain operating. Exelon also looks forward to continuing ENGIE’s mission of providing safe, reliable LNG to gas utilities, marketers, and other market participants throughout New England.
Transaction closure is dependent upon regulatory review by the U.S. Department of Energy for LNG import authorization and, as necessary, authorization from the U.S. Department of Justice. The transaction is expected to close in the fourth quarter of 2018.
The Everett Marine Terminal, also known as the Distrigas Terminal, is the longest-operating LNG import facility of its kind in the United States. The facility has connections with two interstate pipeline systems, as well as a local gas utility’s distribution system. It employs 50 people and pays $7 million in state and local taxes.
Mystic Generating Station is a 2,000 MW natural gas- and oil-fueled power plant. Mystic Units 7, 8 and 9 are the operating units at the plant; Units 1-6 are decommissioned. Mystic employs 110 full-time workers, more than 200 local union craftsmen for seasonal readiness outages, and pays $15 million per year in local taxes that support municipal government, schools, libraries, parks and other services. Exelon is committed to holding informational meetings with employees over the next several months to ensure transparency throughout the process.
