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).

Around 20,000 people live in the Broken Hill area. Over $650 million in investment made Broken Hill home to a 200 MW wind plant, a 53 MW solar array, and a large battery that could provide 50 MW of power for 100 MWh through advanced grid forming inverters. Broken Hill is home to over 6,000 small-scale solar systems providing a per capita energy small solar production level almost twice the Australian average.  The area also contains two poorly maintained diesel-powered gas turbine generators in the area, one which was off-line for maintenance.

Broken Hill became renewable energy industry’s Potemkin Village:

 In 2018, Broken Hill City Council announced its goal to become Australia’s first carbon-free city by 2030. Three years ago, then mayor Darriea Turley welcomed the announcement that AGL was proceeding with plans to build a grid-scale battery, which the company claimed would be a reliable backup power source for 10,000 homes. “This is a great opportunity for Broken Hill and renewable energies,” Turley told the ABC. “What they will see is when there is an outage, the battery would click into operation.” (continue reading)
