Addressing Wind/Solar Instability: Hardwiring the Grid
By Ed Ireland -- April 17, 2023
The near failure of the Texas power grid, coming just 4 minutes and 37 seconds from a complete collapse on February 14, 2021, was the first alarm bell that something was dreadfully wrong with US power grids. Meredith Angwin, a physical chemist and power grid specialist, described the February 2021 failure of the Texas power grid failure as a seminal event that was not a surprise:
Those of us who were watching the grid had noticed for years that Texas ran with a very low reserve margin…and there were predictions that Texas was going to be in trouble, [1],”
Since then, more power-grid operators have been speaking out about the increasing instability of their grids due to an over-weighting of non-dispatchable wind and solar power. A report on February 24, 2023, from the largest power grid in the US, PJM, warned of “increasing reliability risks” affecting 13 states and the District of Columbia and 65 million people who get their power from PJM. This report is a wake-up call for all US power grids because most face the same grid instability problems highlighted in the report:
