Im Börsengroßhandel bestimmt die inzwischen teure Stromerzeugung durch Gaskraftwerke oft den Strompreis für alle anderen Erzeugungsarten.
Translation: In the meantime the expensive wholesale market electric generation rates for all types of generation are set by gas power plants.
This is the point that's not talked about nearly enough. Wholesale electric rates are determined by bids every day. The winner is the supplier that offers the highest price, and everyone else gets that price as well. With gas prices in the EU having increased something like ten times the previous decade average that means electric retail companies are paying incredibly high rates to power the grid, and those costs are passed directly to individual people. Meanwhile the "excess profits" of electric suppliers beyond a certain nominal price per MWh are being taxed by governments and given right over to the retail utility providers as a "subsidy." There's no requirement for the retail companies to cut consumer rates, and in many cases the generation and retail companies have the same owners.
It's a system which IIRC a certain "there is no alternative" Peggy Thatcher introduced in the eighties and now it's essentially EU electric price policy.
