ISO-NE Internal Market Monitor issues annual report

May 23, 2019

The 2018 Annual Markets Report concluded that New England’s wholesale power markets were competitive in 2018. Increases in energy prices were driven by higher natural gas prices during winter and higher power demand during a hot and humid summer. Higher capacity costs reflected higher clearing prices in the eighth and ninth FCAs after a spate of generator retirements. Capacity costs will begin to decline after June 2019, reflecting the entry of new resources and a higher capacity surplus.
