Energy ministers of the European Union put an end to a monthslong battle to agree on a price cap for natural gas in the bloc with 180 euros ($191.2) per megawatt hour.
"It wasn't an easy thing to achieve," Maltese Energy Minister Miriam Dalli said.
The agreement, set out in a European Council statement, unlocks other pre-agreed measures to mitigate an energy crunch Europe is facing as a consequence of Russia's war in Ukraine.
They include joint gas purchases, a future new benchmark for pricing gas, and speedier authorizations for renewable energy sources.
It took four months for the 27 EU member states to overcome divisions on the issue.
One camp wanted to urgently bring down gas prices sent soaring by Russia's war in Ukraine by limiting how high the price for gas used in electricity generation could go.
The other, led by heavyweight Germany, was leery of a too-easily-triggered price cap that could scare off liquified natural gas (LNG) supplies to more lucrative markets in Asia.
In the end, Germany voted in favor of the 180-euro price cap, which was sharply lower than the 275-euro limit initially proposed by the European Commission.
Tough conditions the commission had suggested for triggering the price cap were significantly eased, but strings were still attached.
The EU document said the price cap regime — in force from Feb. 15 — would require the 180-euro limit to be breached for three consecutive days, instead of the two-week period initially suggested by the commission.
It would also require the month-ahead price for gas in Europe to be at least 35 euros more than that paid for LNG on global markets.
Europe's benchmark price for natural gas delivered via pipeline was trading at just under 112 euros per megawatt hour on Monday. It briefly soared to nearly 340 euros per megawatt hour over the summer.
"We have managed to reach a very important agreement on the price ceiling for gas," said Czech Industry Minister Jozef Sikela, who chaired the meeting under his country's EU presidency.
"Europe will thus have a package of measures to help it prepare for next winter and protect citizens and businesses from extreme price volatility."
It was "not easy to understand its ultimate impact, given all the safeguards included," tweeted Simone Tagliapietra, an expert at the Bruegel think tank in Brussels who analyses EU energy issues.
"This is no silver bullet," he warned, saying EU countries still needed to cut back on public and business demand for gas-powered energy and to focus more on transitioning to greener sources.
France's energy minister, Agnes Pannier-Runacher, said that, with the price cap agreed, attention must now turn to a longer-term reform of the EU's energy market, notably unhitching the price of gas from that of electricity.
Russia slams price cap decision
Kremlin spokesperson Dmitry Peskov said that the EU decision to set a cap on the price of gas from Feb. 15 was an attack on market pricing, and unacceptable, Russia's Interfax news agency reported.
