Tracking the evolution of the OMIE standard average wholesale electricity price over the last heavily volatile years.
Price in €c/kWh (OMIE Pool)
The Spanish electricity market has experienced unprecedented volatility over the past five years. Reviewing the historical data above highlights several profound macroeconomic shifts.
During the lockdowns of 2020, industrial and commercial activity plummeted, causing electricity demand to crater. The average wholesale price fell to historic lows, averaging around 3.4 €c/kWh.
As global economies rebooted and geopolitical conflicts severed European gas supplies, the marginal pricing model of the OMIE meant that expensive natural gas set the price for nearly all electricity generated. Prices skyrocketed to catastrophic levels, peaking at an average of nearly 21 €c/kWh in 2022. During this period, consumers on the regulated PVPC tariff suffered the most immediate impacts.
Driven by necessity and the "Iberian Exception" (which decoupled gas pricing from electricity), Spain accelerated its deployment of utility-scale solar and wind.
By 2024 and beyond, the massive influx of zero-marginal-cost renewable energy—especially during daylight solar hours—caused prices to crash back down, frequently resulting in hours with effectively zero or negative prices. This stabilization makes Spain one of the most competitive electricity markets in Europe once again.
