The Great Decoupling

Electricity (cross-product) price volatility has historically been closely linked to overall price levels. This trend seems to have ended in 2024 in Germany, as low marginal cost renewables are pushing the overall wholesale price level down, while peakers such as gas and batteries need to finance their investments in relatively few but increasingly expensive production hours
