In January 2019 the European Commission published the third report on energy prices and costs in Europe. Published every two years, this most recent report finds that wholesale energy prices have fallen in recent years due to increasing competition on wholesale markets from greater amounts of renewable energy, improved interconnections and a more integrated internal electricity market.
The report also highlights how these lower supply costs, together with stable network tariffs, taxes and levies, enabled household electricity prices to fall in 2017 for the first time since 2008. However, the report also warns of the EU's ongoing high exposure to volatile and growing fossil fuel prices and notes that wholesale prices have started to rise again. Future electricity production costs are expected to increase for fossil fuel-generated electricity (due to import prices and the carbon price) and fall for renewables (linked to the decreasing costs of investment as technologies evolve), with the report suggesting that that electricity market prices could reduce the need for subsidising renewable energy technologies by 2030.
