In Ukraine, they came up with how in winter to protect energy from Russian strikes - WSJ
Last winter, Ukraine's energy has withstood large -scale shelling, but the situation has changed: Russia has significantly increased the production of percussion drones, which increased the threat to energy infrastructure. According to WSJ, the future heating season can be the most difficult since the beginning of the war. A key element of the new strategy was the battery parks of about 200 megawatts. They are able to provide energy up to 600,000 consumers for two hours.
The main purpose of such systems is to give engineers time to repair damaged networks after rocket strokes and avoid fan shutdowns. According to the publication, six facilities are already operating in Kyiv and Dnipropetrovsk region. However, their accurate location is kept secret to prevent infrastructure, and all objects are covered with air defense systems. The battery supplier is the American company Fluence.
According to its CEO Julian Nezhada, the systems have a modular structure - each block can be replaced without stopping the entire network. In addition, all modules are equipped with fire protection and a system of emergency shutdown, which is especially important in constant shelling. Ukraine also develops wind and solar energy to reduce the dependence on thermal and nuclear power plants.
Despite the fact that renewable sources cannot completely replace traditional, they increase the stability of the power system. In the event of a defeat, for example, one turbine continues to work unlike thermal stations, which completely stop in case of damage. In such a situation, batteries play a dual role here: they regulate the supply of electricity from variable sources and provide reserve power when the sun does not shine or the wind weakens.
