Wind and Solar Can’t Support the Grid

In October of 2024, the isolated small city of Broken Hill in New South Wales, Australia with a 36 MW load (including the large nearby mines) could not be reliably served by 200 MW of wind, a 53 MW solar array, significant residential solar, and a large 50 MW battery all supplemented by diesel generators.
Many people falsely believe that wind, solar and batteries have been demonstrated to provide grid support and deliver energy independently in large real word applications. Few people realize that we are a long way away from having wind, solar and batteries support a large power system without significant amounts of conventional spinning generation (nuclear, gas, coal, hydro, geothermal) on-line to support the grid.
Broken Hill Outage – Wind, Solar and Battery Can Not Support the Grid
The recent outages occurring in Broken Hill help illustrate the inability of wind, solar and batteries to support electric grids without significant help from machines rotating in synchronism with the grid. (Note – wind power is produced by rotation but not in synchronism with the grid).
