Coal, Electric Power
September 10, 2025
Platts, part of S&P Global Commodity Insights, will discontinue the Platts Dark Spreads for the UK, following the phasing out of coal-fired electricity generation in the UK, from Nov. 19, 2025.
The UK's last remaining coal-fired power plant, Ratcliffe-on-Soar, was shut down Sept. 30, 2024, after more than five decades of operation as Britain made the commitment to phase out coal-fired power generation.
While coal has long held only a minor share of the UK power mix, Ratcliffe's closure was a symbolic milestone in the country's quest to fully decarbonize the power sector by 2030.
Platts proposed the discontinuation of its Dark Spreads for the UK in a subscriber note published Aug. 27, available here: Platts proposes to discontinue Dark Spreads for the UK | S&P Global .
