No extra power for sale during Christmas storm that led to rolling blackouts for Duke Energy customers
Duke Energy's rolling blackouts across the Carolinas Christmas Eve were the result of malfunctioning equipment - and a lack of power to buy from elsewhere.
Duke had been counting on supplementing its own power generation with electricity from PJM, which operates the electrical grid from the mid-Atlantic to the Midwest.
But PJM reported this week that it lost 23% of its power generating capacity due to storms and cold weather.
As with Duke, most of PJM's problems came from cold-related malfunctions at coal- and gas-fired power plants. That meant there was no extra power for sale.
Duke has said the December 24th blackouts affected a half-million customers in the Carolinas.
