As temperatures dropped dramatically over the Christmas weekend, Dominion Energyโs advice to its customers โ those who still had power โ was to turn down their thermostats. Virginia was not alone. PJM, the regional grid management organization covering 13 states and the District of Columbia, made the same request because its gas plants couldnโt get enough fuel to meet the demand for home heating.
According to The Wall Street Journal, rolling blackouts were averted because PJM ordered some businesses to curtail power while switching some generators to oil. The large regions served by both the Tennessee Valley Authority and Duke Energy experienced rolling blackouts. And for the second year in a row, Texas faced a grid problem as wind power plunged and demand doubled.
The Wall Street Journal also noted that, โWhile there wasnโt a single cause for the power shortages, government policies to boost renewable energy snowballed and created problems that cascaded through the grid. There have been warnings about grid vulnerability for years but this Christmas proves that these warnings have not been taken seriously. The climate lobby blames climate change and greedy energy companies for this yearโs problems but there have been colder Christmases โ 1980 and 1983 for example. And, there have been colder Decembers that were survived without a grid breakdown or near breakdown.
The problems faced by utilities should be a warning and a reason for reassessment. Will Dominion heed that warning or will it continue on its present course? How will it prevent more serious problems as the demand for electrical power continues to increase and electric heat pumps are promoted and subsidized as responsible replacements for gas- and oil-fired furnaces?
That Dominion had to urge its customers to turn down their thermostats indicates that it did not have sufficient surge capacity to meet the demand caused by low temperatures. We need to know why. It could be the result of the 2019 decision to shutter all of its coal-fired capacity as part of its Net-Zero 2050 commitment and the General Assembly mandate to do so by 2024.
