German 3Q hard coal output falls on reduced fleet

German 3Q hard coal output falls on reduced fleet

London, 8 October (Argus) — Hard coal-fired output from German utilities dropped by 23pc on the year in July-September, largely driven by a smaller generation capacity following a series of plant retirements or returning to grid reserve in the first half of 2024. German hard coal-fired generation averaged 2.1GW in the third quarter, according to European grid operator Entso-E. Compared with a year ago this was equivalent to around 505,000t of NAR 6,000 kcal/kg coal consumption, assuming 40pc efficiency plants. September output reached a seven-month high of 2.9GW, but it was down by 15pc from a year earlier. Germany's overall available hard coal-fired capacity was 6.5GW in September, cut by 1.6GW on the year, based on European Energy Exchange (EEX) data. The German hard coal fleet's implied load factor was 45pc in September, slightly higher than 41pc from a year ago. Trianel was the German utility with the highest hard coal-fired generation in July-September, as it raised the output from its sole 750MW hard coal plant Lunen 1 in northwest Germany by 28pc on the year to 380MW. Oynx meanwhile produced the second-highest hard coal output in the third quarter, averaging 352MW, as it was the generator with the sharpest rise in coal burn from a year earlier at 53pc. This was despite the company closing its 350MW Farge plant in March. Phase-out weigh on coal burn Uniper was Germany's largest hard coal-fired operator in the third quarter of last year, but its hard coal output halved on the year to just 316MW in July-September because the utility took off the bulk of its fleet from the market. Only the 1.05GW Datteln 4 plant was running in the third quarter, given Uniper placed its four other hard coal-fired units — the 345MW Scholven B, 345MW Scholven C, 522MW Staudinger 5 and 875MW Heyden 4 — into the grid reserve earlier this year. The company could no longer run hard coal plants within Germany in the near future as it seeks to sell Datteln 4 plant . Similarly, fellow utility EnBW transferred its 517MW Karlsruhe RDK 7 into the reserve in late May, which contributed to a 35pc on-year fall in its total hard coal-fired generation to 248MW in July-September. Steag took off a larger capacity of hard coal assets — around 2GW from three sites in Saarland — from the market in the first half, resulting in a 32pc drop on the year to 99MW in the third quarter. Smaller operators likewise exited coal this year, with Bremen-based SWB shutting down its 119MW Hastedt 15 hard coal-fired unit in the end of April. The municipal utility has already replaced Hastedt 15 with a 104MW gas-fired combined heat and power plant . In addition, Czech utility EPH retired the 690MW Mehrum 3 plant in late March, having returned to the market in August 2022. Elsewhere, Wolfsburg-based industrial user Volkswagen decommissioned its two 138MW coal-fired units in March as the company opted for coal-to-gas fuel switching. Firm renewables supress thermal generation Wind and solar output rose on the year in the third quarter, crowding out not only hard coal but also gas and lignite within the German power mix. Combined wind and solar generation averaged 23.3GW during July-September, up by 12pc on the year. Solar output alone picked up by 2.1GW, owing to a higher load factor and increased installed capacity. Considering hydro and biomass generation also incrementally rose on the year in the third quarter, the overall strength in renewables meant Germany had to cut down thermal power output and cross-border imports in a bid to balance out with the demand, which only rose by 3pc on the year to 54.8GW in the same period. Consequently, thermal generation from hard coal, gas and lignite all fell on the year in the third quarter, but lignite dropped to 7.4GW at a slower rate of just 4pc compared with other fuels because of its low fuel procurement cost. German lignite-fired plants typically source their fuel from nearby mines. German gas-fired output was down by 26pc on the year to 7.1GW in July-September, in part owing to theoretical spark spreads deteriorating from a year earlier. In the beginning of the third quarter, a typical 55pc-efficient gas-fired plant using German VTP supplies was ahead of a 40pc-efficient German hard coal-fired unit on a month-ahead basis, but in the end of the quarter, such coal-gas fuel switching dynamics flipped (see chart).
