A steep rise in gas prices during the third quarter significantly improved the profitability of coal-fired power generation in Europe.
In August, NWE front-month clean dark spreads for 40pc-efficient units recorded on average a €8/MWh premium over clean spark spreads for 55pc gas plants, while in September the gap between the two indicators surpassed €35/MWh.
Given the acute vulnerabilities in the UK energy system, everyone’s attention has been especially drawn to that country in recent weeks. To avoid shortages in electricity supply, Britain was forced to fire up its remaining coal power plants.
Utilities on the other side of the English Channel did the same thing in late summer. For instance, September’s share of electricity coming from coal in Germany reached its highest level since the end of 2018, while the weight of coal generation in the electricity mixes of Italy, the Netherlands and France combined rose by more than 4 percentage points over the past month. In other market environment, a big portion of the coal-fired units, which are in use now, would obviously not be brought back to life.
As coal power plants are still operating far below capacity in Western Europe, there is potential for intensifying their usage. The question is what effect further fuel switching to coal may have on gas market in today’s conditions?
