Oct 23, 2018, LONDON (IEEFA) – In a report released today, the Institute for Energy Economics and Financial Analysis finds that German utility RWE would benefit in the medium to long term by moving now to sharply reduce its lignite mining activities and begin closing its oldest lignite-fuelled generation stations.
The report, “Lignite Retreat: RWE’s Short-Term Pain, Long-Term Gain,” finds that RWE could save at least $100 million in avoided capital expenditures by deciding not to extend the life of ageing, marginal power plants. Such a move would also significantly reduce the utility’s carbon dioxide emissions and speed its corporate makeover into a renewable energy generation major.
“It does not make sense to invest funds to extend the life of marginally profitable power plants that are nearly 50 years old, as RWE is planning, to comply with emissions standards that come into force in 2021,” said report co-author Gerard Wynn. “This is especially true since Germany’s Coal Exit Commission is on the verge of announcing a national coal phaseout date.”
The report examines the controversy surrounding RWE’s plans to expand its Hambach mine, which has sparked significant protest in Germany and is now on hold pending the outcome of a court case. Specifically, Wynn and co-author Paolo Coghe study one potential option for RWE, which would involve cutting its lignite production in half at Hambach and the neighbouring Garzweiler mine and closing a number of its oldest power plants.
In the short term, this could cut company profits due to foregone electricity sales. But in the medium to long-term such a move would be fiscally prudent, the authors concluded.
RWE will be one of the energy companies most affected by an expected coal phaseout in Germany because of its substantial lignite and hard coal assets, which account for some 60% of its installed capacity.
“RWE’s Niederaussem and Neurath power plants are only marginally profitable under central scenarios from around 2022,” said report co-author Paolo Coghe. “Factoring in the age of these power plants, and the extra investment required to meet environmental upgrades, we are unconvinced of a significant net cashflow benefit from continuing to operate older units.”
“Sharply lowering lignite production may indeed be a painful transition for RWE, especially as the economics of its wider mining operation may not then stack up. But the question for RWE is, how long does it intend to continue mining at scale for diminishing returns?”
