All right, I have one more, but this time it's positive:
Economics from Above #353 – Energy Storage These images show the worldwide boom in battery storage.
Exclusive satellite images reveal: Gigantic battery parks are springing up worldwide, storing solar and wind power – and making entire nuclear power plants obsolete. "Economy from Above" is a collaboration with LiveEO. November 4, 2025 - 12:02 PM
Until 2012, a coal-fired power plant belched smoke at Munmorah Lake, 80 kilometers north of Sydney. But since the beginning of August, electricity has been stored here emission-free in 3,500 white containers: A huge new battery storage facility has gone into operation, which stores energy from solar and wind power plants and balances fluctuations in the electricity grid.
The "Waratah Super Battery," with a storage capacity of at least 1.4 gigawatt-hours, can supply around one million households with electricity for one hour or 80,000 households for an entire day. With a capacity of 850 megawatts, it is expected to be as powerful as a large coal-fired power plant by the end of the year.
This project is just one example of a global trend: the energy storage market is booming. According to market analysts Rho Motion, as reported by the portal Energy Storage News, 136.5 gigawatt-hours (GWh) of battery storage capacity were connected to the grid worldwide by the end of September – more than three times the capacity of all German pumped storage power plants (40 GWh).
China is driving expansion most aggressively, planning to add another 180 GWh of battery storage capacity by 2027.
Unlike pumped-storage hydroelectric plants, for which there are hardly any new sites available in
Germany , battery storage systems are compact, come in practical containers, and can be easily installed, for example, next to a solar power plant. And they have become so inexpensive that large-scale construction is now financially viable. According to the Fraunhofer Institute for Solar Energy Systems, solar power plants with integrated batteries in Germany supply significantly cheaper electricity than coal and gas-fired power plants.
The technology providers are now also positioning themselves as a solution for periods of low wind and solar power generation, extended periods with insufficient wind and sunshine. The German government is currently planning primarily new gas-fired power plants for this purpose. The German-Norwegian company Eco Stor has now presented an analysis showing that 1000 GWh of battery storage – or 125 gigawatts of capacity over eight hours – could reduce the required reserve power plant capacity by 30 gigawatts. However, the analysis acknowledges that Germany cannot guarantee a secure energy supply without any reserve power plants at all.
Currently, numerous battery storage facilities are planned in Germany, and many are already under construction. This week, construction began on a 0.7 GWh storage facility on the site of the former Gundremmingen nuclear power plant in Bavaria. When completed, it is expected to be the largest battery storage facility in Germany. This record is currently held by a facility near Bollingstedt in Schleswig-Holstein, which went online this summer.
Across Europe, battery storage is booming. In 2024, the European battery fleet grew to 61 GWh, according to a study by the industry association SolarPower Europe: "This means that one-third of all batteries installed in Europe were built in just one year." The study predicts that by 2029, the Europe-wide battery park will have grown to 400 GWh.
The largest wind energy plant in Europe began operating in March in Scotland near the village of Keith (population 5,000): At the Blackhillock substation, batteries with a capacity of 0.4 GWh help stabilize the electricity grid, into which increasing amounts of wind power are being fed. The plant is expected to grow by another 50 percent next year.
are still
China and the USA the leaders in installed battery capacity, with around 215 and 82 gigawatt-hours respectively by the end of 2024, according to market analysts Rho Motion. China plans to install another 180 GWh by 2027, with leading battery manufacturers such as
CATL.
The country also dominates production.
In the US, some of the world's largest battery projects have gone into operation in recent years. The market there grew by 60 percent in 2024, according to analysts at Rystad Energy. At its peak, batteries in California already covered 30 percent of the country's electricity demand, the experts say. The sunny state operates the world's largest battery storage facility in the Mojave Desert.
