Italy mulls keeping its last coal plants on standby

After retiring the two remaining mainland coal power plants, scheduled for this year, Italy’s government intends to switch the facilities to standby instead of dismantling them. Two others are on the island of Sardinia, which is waiting for another subsea interconnection to complete the coal phaseout.

Italy has 4.7 GW in coal power capacity left, following the recent retirement of A2A’s plant in Monfalcone, on the border with Slovenia. The two facilities that remained on the mainland are only marginally active and they are officially set to be closed this year. However, Minister of the Environment and Energy Security Gilberto Pichetto Fratin expressed the belief that they should be kept on standby.

“Therefore, not producing, because it is not economically suitable. But the geopolitics are still in a state where no one can guarantee us that gas will not reach EUR 70 per MWh or that there will be no malfunctions in the pipelines that supply us,” he argued. The said facilities, already dormant as they are not cost-effective, should be kept just in case, in the view of the minister. He didn’t address the pollution issue.

Provisional data showed that coal power output nosedived 71% in 2024 to 3.5 TWh. It translated to a share of 1.3% in electricity production and 1.1% in consumption.

On the one hand, the capacities would be valuable in case of gas and power supply disturbances. But it comes at the cost of maintaining a complex system idle.

Sardinia may remain dependent on coal by 2029

The two mainland coal plants are Enel’s Torrevaldaliga Nord in Civitavecchia and Brindisi Sud.

There are two more, in Sardinia, scheduled to be phased out by January 2029. By then, the island’s interconnection with the main grid should be strengthened with the proposed Tyrrhenian Link. The Sulcis coal plant is also Enel’s, and the other one is EP Produzione’s Fiume Santo power plant. Together, they have 1.1 GW in nominal capacity.

Speaking at the same event, Chief Executive Officer of Enel Flavio Cattaneo warned of the expected surge in power consumption, suggesting the coal exit be reconsidered. The “perfectly functioning” plants, which “saved” Italy during the gas crisis, will be closed by August, he stressed. The company is open to selling its coal assets, Cattaneo said and hinted at the possibility that the government buys them.

AI, data centers bolstering demand for nuclear energy, gas, coal

Eni’s CEO Claudio Descalzi said it was “pure madness” to close coal-fired power plants “in a situation of high costs or low energy availability.” He cited the rise of artificial intelligence and data centers, boosting energy demand, and the need to keep costs low. “It is only possible with nuclear, gas and coal,” Descalzi claimed.

Closing coal plants is not in the country’s interest, said Deputy Prime Minister of Italy and Minister of Infrastructure and Transport Matteo Salvini.

A group of environmental organizations called it unacceptable in 2025 to propose coal to be part of the energy mix.

Italy is no longer buying Russian gas

Minister Pichetto Fratin also said Italy has stopped buying gas from Russia at the end of last year. It turned to alternatives like liquefied natural gas (LNG) from the United States, he added.

The country needs to rapidly deploy renewables, in his view, and decouple the prices of electricity and gas. Pichetto Fratin said gas accounts for 40% of power but that it determines 70% of the final price, and criticized the pricing system based on the Netherlands’ TTF benchmark.

The government is considering support for long-term power purchase agreements (PPAs) and contracts for difference (CfD), to stabilize prices and become competitive with Germany. It is also the European Union’s policy, under the latest electricity market redesign.
