* S&P says coal and nuclear plants closures to boost prices
* Market volatile due to increased renewables
* EDF, Fortum, Verbund Statkraft, Uniper to gain
PARIS, Nov 8 (Reuters) - European wholesale electricity prices could soar by around 30% by 2025 due to a recovery in gas and carbon emissions prices and the planned phase out of some coal and nuclear power generation units, S&P Global rating said in a report on Friday.
S&P said the supply gap would likely be filled by the rise in renewable solar capacity in Europe which could increase to 43% of the electricity mix from 23% in 2018.
“We believe the growth of renewables will imply more weather-dependent volatility in prices and will require grid investments and backup solutions to ensure supply security,” S&P Global Ratings credit analyst Massimo Schiavo said.
Utilities such as France’s EDF, Norway’s Statkraft AS , Finland’s Fortum Oyj , Germany’s Uniper SE , and Austria’s Verbund AG stood likely to benefit from this trend, he said.
“However, the credit impact of the forecast rise in power prices on most of the large European utilities we rate should be more limited because their EBITDA sensitivity to merchant power has decreased markedly,” the report said.
S&P said wholesale power prices are set fall in 2020 compared with 2019 but will rise across all markets until 2023 due to a combination of increased fuel and carbon emissions permit prices, and the “large-scale” power plant closures.
It said Germany, a net European power exporter, could increasingly become reliant on imports due to a high level of nuclear and coal-fired generation closures scheduled over the next few years.
France also plans to shut down its remaining coal power plants by 2022, and will halt production at its oldest nuclear plant at Fessenheim by summer next year.
“We expect installed hard coal and lignite capacity to drop 60% to 2025. A number of markets go “coal free”—starting with France in 2022, followed by the U.K., Spain, and Italy by 2025,” the report said.
The largest volume of closures is in Germany, which would see coal-fired capacity drop by 35%, reflecting targets set out in its coal commission report, S&P said.
Nuclear generation capacity in Europe is expected is to fall 19%, with the main losses in Germany and Belgium, which go nuclear free in 2022 and 2025.
The report said French nuclear capacity levels should remain stable, with the only closure being the 1.8 GW Fessenheim plant, which would be replaced by the 1.6 GW Flamanville 3 EPR under construction in the north of France.
Flamanville 3, which was meant to start 2012 has suffered several delays and is now scheduled to start in 2023. (Reporting by Bate Felix; Editing by Simon Cameron-Moore)
