![]() In most European countries, the role of fossil fuels in setting electricity prices has increased from 2015 to 2019, despite fossil fuels producing a declining share of total electricity as coal production has declined. In the UK, Italy and Spain, more than 80% of the time, electricity prices were following the supply bids of natural gas generators. This varied across Europe, from a high of 91% dictated by fossil fuels in Germany (primarily coal), to a low of 7% in France, where electricity prices are primarily dictated by nuclear energy production. They find that across the region, fossil fuel electricity generation dictated electricity prices 66% of the time, despite only 37% of electricity being derived from fossil fuels. ![]() In the first paper, they review electricity sources and costs in the European Union, the UK and Norway. This will culminate in two major reports to be published in November 2022 and May 2023, that propose clear solutions to these problems.ĭue to the urgency of the current crisis, the researchers are publishing interim papers that outline the economic fundamentals of the UK’s electricity market design present key principles for reform examine the revenues collected by generators during the crisis and put forward a vanguard proposal for a ‘Green Power Pool’, that would decouple gas and electricity prices, enabling consumers to benefit from the falling costs of renewable energy generation. Bbc iplayer uk series#The two papers are the first outputs of a programme of research led by UCL supported by the Aldersgate Group and the Institute for New Economic Thinking, which is leading to a series of proposals for electricity market reform, power sector decarbonisation, and measures to reduce electricity prices to facilitate the electrification of the UK economy. Because natural gas generation is expensive, those producers charge the highest prices – which means that other producers are also able to charge similar prices.” The research programme: Navigating the Energy-Climate Crisis The most expensive natural gas producers are still needed to cope with fluctuations in renewable energy production, so they are setting what’s called the marginal cost, at the edge of what’s needed. Professor Grubb explained: “While renewables are providing more and more electricity, we still need natural gas to meet the demand. This happens even when the bulk of electricity is generated by cheaper renewable sources. Bbc iplayer uk generator#In their reports, the researchers explain how, as the most expensive generator needed to meet the last bit of demand, gas sets the price for all types of electricity generating technologies. ![]() ![]() But the structure of the UK’s power market means that these falling costs are not reflected in bills. Yet the UK already generates half of its electricity from non-fossil sources, with 25% from wind and solar power, whose costs have fallen hugely to around a quarter of the costs now seen in the wholesale market. The ongoing energy crisis has pushed retail prices up by over 80% this year, and quadrupled wholesale prices, fuelling the ‘cost of living’ crisis and inflation. ![]() “If we actually paid the average price of what our electricity now costs to produce, our bills would be substantially cheaper.” Half of our electricity already comes from non-fossil fuels, and that figure is growing. Professor Michael Grubb (UCL Institute for Sustainable Resources), who is leading the research, said: “Fossil fuels used to be cheaper than renewable energy sources, but that has turned on its head as gas prices shot up and the cost to produce renewables such as wind and solar power has plummeted. Bbc iplayer uk driver#The working paper authors identify the structure of the wholesale electricity market as the main driver of excessive prices, and are developing solutions to change this. As a result, revenues of large electricity generators operating directly in the British wholesale market have increased from nearly £15 billion in 2019 to roughly double in 2021 and likely to over £50 billion in 2022. In two papers being published today, researchers outline reasons why, despite the advance of relatively cheap renewable energy, electricity prices have rapidly risen across Europe alongside the increased cost of natural gas. Research published by UCL confirms that natural gas is the main driver of electricity prices across Europe in the UK, in recent years it set electricity costs 84% of the time, despite providing well under half of the total electricity. ![]()
