Several countries in Europe have experienced negative power prices, including Belgium, Britain, France, the Netherlands and Switzerland. Still, its experiences of negative prices are often longer, and deeper, than other countries. In one recent example, power prices spent 31 hours below zero during the last weekend of October. Negative prices indicate that Germany’s power grid, like most others around the world, has not yet adapted to the increasing amounts of renewable energy being produced. While negative prices create problems for the company, they also enhance the value of its more flexible installations, including large storage systems.
