Australia has invested in batteries for grid security. It’s not going as planned.

Australia’s two large lithium-ion storage batteries are getting attention for all the wrong reasons. Hornsdale Power Reserve, a 150-MW battery collocated with a wind farm in South Australia, is being charged in federal court with failing to deliver on promises to respond to grid demands, and of being technically unable to deliver under the terms it was being paid to meet. Proceedings were filed September 22, just before the testing of a second Tesla-manufactured “Big Battery resumed after a two-month delay following a fire in July.

Germany: Coal tops wind energy in 2021, but there’s more to the story

Coal-fired plants fed the most power to Germany's electricity grid in the first half of 2021, while wind power dropped to its lowest level since 2018. As a September 13 article published on the German news site explained, the situation was blamed in part on a wind energy shortfall that is causing power price spikes across Europe.

The economics of wind power

It is often stated that since no one can charge money for the wind, wind-generated electricity is free. This is not true. A modern wind turbine, which can generate 2 megawatts of electricity (MWe) when the wind is blowing, costs about $3.5 million installed. Five hundred of these turbines installed at a wind farm, to be able to generate 1000 MWe, would cost $1.75 billion. Add in other costs, such as for operation and maintenance (O&M) and transmission lines, and the total sum could match the approximate $4 billion required to build a nuclear plant.
