French Wind Proves Huge Value To Grid
Wind farm proves it can provide cheaper, more precise grid security than gas generators
Giles Parkinson, 13 March 2018 (ReNew Economy)
“…[Results are in on the ground-breaking first trial using a wind farm to provide frequency control and ancillary services (FCAS) to the Australian grid. It shows the Hornsdale 2 wind farm, part of the huge 315MW Hornsdale wind complex that includes the Tesla big battery officially known as the Hornsdale Power Reserve,] had cut prices and delivered a more ‘precise’ service to the market operator…[It was also significant because] it coincided with a major ‘peak’ FCAS event – caused by maintenance work on the inter-connector to Victoria – that would have sent prices to $9,000MW or more in normal circumstances…[T]he intervention of the Hornsdale wind farm, along with the Tesla big battery, slashed those prices to $300/MW…It was the first concrete sign of how new technologies could break up the fossil fuel cartel that had been extracting high prices from the grid for years…[The FCAS delivered by the Hornsdale turbines over the trials delivered greater response precision, when compared to conventional generators, and provided an ‘enhanced stabilisation’ of the electricity grid…” click here for more
