German Coal Exit to Trigger Price Swings in Energy Markets
(Bloomberg) -- Germany’s plan to shut down dozens of power plants burning coal over the next couple of decades is uniting traders and analysts on one thing: price swings in markets from power to natural gas and carbon allowances are poised to increase.
Renewable energy last year overtook the dirtiest fossil fuel as Germany’s biggest source of electricity. Closing coal stations that are designed to provide stable output from the grid, coupled with the continued expansion of solar and wind plants, will give volatile green sources an even larger share of total output in the future.
Traders are on tenterhooks for any clues as to how severe the start of the exit will be. News could emerge in days ahead of a report by the nation’s Coal Commission due on Feb. 1. While the overall phase-out will last until the late 2030s in order to protect the industry’s 50,000 jobs and local economies, how much capacity will go in a first phase over the next few years is key for energy markets.
“Germany’s coal phase-out is likely to drive even greater volatility in order for the continent to meet requirements in periods of low intermittent renewable supply,” said Nick Campbell, a risk manager at industry consultant Inspired Energy Plc.
The commission has delayed its publication at least twice. Europe’s biggest economy, already set to miss its 2020 target to cut carbon emissions, will start to phase out the fuel to help meet the obligations under the 2015 Paris Agreement for the next decade.
Key variables traders and analysts are adding to their carbon, natural gas, coal and power models are:
- Total capacity to be shut down
- Timing for closures
The question of how much power plant capacity should be shut down is still under discussion. Environmental groups, including the Europe Beyond Coal network, believe that Germany should shut at least 16 gigawatts of capacity by 2022 in order to put itself on a pathway to reach its obligations under the Paris Agreement.
“We hope that effort would be scaled up toward a full phase-out by 2030 or sooner,” said Kathrin Gutmann, campaign director at the network, which includes WWF, Greenpeace and other groups.

Here is what traders and other analysts expect will happen in the market once we know more details of the phase-out:
- News on the coal closure has already to some extent been priced into Europe’s energy markets, says Guy Smith, head of gas trading.
- To ensure that national measures lead to reduced carbon emissions in Europe, a cut in the volume of carbon permits would be necessary. Policy makers are encouraging green power developments and want to keep costs of emitting high to benefit renewables
- Natural gas can be used as a transition fuel in the context of dismantling coal capacity.
- If Germany starts shutting down lignite faster than predicted, markets might respond fast, said Trevor Sikorski, head of natural gas, coal and carbon research at the industry consultant.
- Price curves will start responding and sentiment will change as closures start happening in the next couple of years. He expects a bigger impact on the carbon market than for natural gas.
- Traders will also watch what the Coal Commission says about the stricter limits set by the European Commission on emissions of nitrogen oxide from lignite coal plants. “In 2021 the restrictions will come to place. The big issue will be whether or not they will comply with it.”
- Significant shutdowns in the first part of the decade will certainly affect prices much more than closures in the latter part of the decade. If shutdowns target lignite more than hard coal, the effect is likely larger since lignite is a domestic power source.
- Spark spreads (the profit margin for gas plants) should increase and the degree of the rise depends on the design of the phase-out policy.
- The German government will have to decide on the volume of carbon permits it sells and if it ends up cutting the quota the effects could be neutral: the decline of emission-allowances demand would be offset by reduced auction supply.
- The phase-out certainly adds a bullish element in the power mix. However, absolute power-price developments also depend on the impact on and from carbon prices and the state of the global gas market, according to Carsten Muench, managing director at Axpo Germany.
- Phasing out lignite stations in Germany “is probably generally supportive of coal and gas contracts in Europe,” said Louis Redshaw, founder of the London-based emissions trader.
- Overlapping policies in Germany are still a risk to some extent in the EU carbon market. It’s not entirely clear if Germany will commit to give up carbon-auction revenue. “The cancellation is supposed to match the emissions reduction so the impact should be neutral.”
- European energy markets are already factoring in a gradual phase-out of coal in Germany and other European markets, according to Artur Lenkowski, senior associate for European power, gas and renewables.
- A key driver affecting German power prices is the addition of renewable capacity which is putting pressure on power prices. The impact of a huge increase of renewable capacity trumps any upside potential from a more rapid coal exit.
- More volatility is expected in natural gas markets as the fuel will more frequently be used at short notice to help meet demand, because renewable energy is difficult to forecast, said Andy Fairley, head of natural gas at Griffin Markets, a brokerage in London.
