Gas-fired power plants accounted for approximately 70% of unplanned outages during so-called Winter Storm Elliott last December, a report released Monday by the country’s biggest grid operator revealed. Nearly one-quarter of PJM Interconnection generating capacity was unexpectedly offline during the storm. “Gas plants and dual-fuel gas plants made up the majority of outages primarily due to mechanical issues likely resulting from the extreme cold,” the report said, along with “a significant level of gas supply issues.” (Utility Dive, E&E $, Politico Pro $)
