Europe weathered the triple crisis
The analysis by Ember reveals that Europe faced a triple crisis in the electricity sector in 2022. Just as Europe scrambled to cut ties with its biggest supplier of fossil gas, it faced the lowest levels of hydro and nuclear in at least two decades, which created a deficit equal to 7% of Europe’s total electricity demand in 2022.
Record growth in wind and solar helped cushion the hydro and nuclear deficit. Solar generation rose the fastest, growing by a record 39 TWh (+24%) in 2022—almost twice its previous record—which helped to avoid €10 billion in gas costs. Twenty EU countries set new solar records in 2022.
Lower electricity demand also helped reduce the deficit. EU electricity demand dropped by 7.9% in the last quarter of 2022 compared to the same period the previous year (-56 TWh), close in scale to the 9.6% fall (-61 TWh) witnessed in Q2 2020 when lockdowns were first imposed across much of Europe. Mild weather was a deciding factor, but affordability pressures likely played a role, alongside energy efficiency improvements and citizens acting in solidarity to cut energy demand in a time of crisis.
Just one sixth of the nuclear and hydro deficit was met by coal. Coal generation rose by 7% (+28 TWh). As a result, EU power sector emissions rose by 3.9% (+26 MtCO2) in 2022 compared to 2021. It could have been much worse: wind, solar and a fall in electricity demand prevented a much larger return to coal. In context, coal’s rise was not substantial: coal power remained below 2018 levels and added only 0.3% to global coal generation.
Coal power in the EU fell in all four of the final months of 2022, down 6% year-on-year. The 26 coal units placed on emergency standby for winter ran at an average of just 18% capacity. Despite importing 22 million tonnes of extra coal throughout 2022, the EU only used a third of it. Countries are as committed to phasing out coal as they were before the crisis.
Perhaps most surprisingly, gas generation was almost unchanged (+0.8%) in 2022 compared to 2021, despite record-high prices. Fossil gas generated 20% of EU electricity in 2022, up from 19% the previous year. However, this trend is expected to change drastically in the coming year.
