Italy reverses coal standby decision with imminent closure of Enel's 3.7 GW fleet
Rome's energy ministry declared permanent closure of Civitavecchia and Brindisi imminent on Wednesday, abandoning a coal contingency that parliament had only codified three months earlier.
Italy's energy ministry announced on Wednesday (2026-08-05) the "imminent authorisation" of permanent closures at two coal-fired power plants with a combined capacity of 3.7 GW, overturning its own standing policy to keep the units available as an emergency backstop. The plants — Enel's 1.86 GW Civitavecchia facility in the Lazio region and its 1.82 GW Brindisi plant in Puglia — had been formally retained on standby because Italian officials judged the grid unable to absorb a rapid coal exit.5
The speed of the reversal is notable. Italy's parliament approved an energy decree on Tuesday (2026-05-19) that explicitly postponed the phasing out of coal-fired generation, according to Montel.1 Within three months of that vote, Rome has moved in the opposite direction on the same capacity.
The gas price logic underpinning the original standby decision has shifted. Energy Minister Gilberto Pichetto Fratin said on Monday (2026-05-18) that mothballed coal plants could be reactivated if gas prices surged above EUR 70/MWh, citing the system's exposure to geopolitical volatility.2 ICE Endex TTF front-month gas closed at EUR 52.20/MWh on 2026-08-05, roughly a quarter below that threshold — a gap that removes the immediate political case for keeping thermal backup available. Pichetto Fratin's contingency was price-conditional; the price has not materialized.
For Italy's power market, Civitavecchia and Brindisi represent capacity that, while on standby, still counted toward system adequacy assessments. Permanent closure removes that buffer from the books. TSO Terna will need to reassess reserve margins, particularly for southern Italy, where Brindisi's 1.82 GW sits at the base of the peninsula — a grid zone already dependent on long transmission corridors from the north.5
Enel's position is more straightforward. The utility has been pushing to reorient its Italian portfolio toward renewables and storage, and Terna-run battery auctions already determine battery project volumes and locations across the country, Enel said in June (2026-06-09).4 Removing aging coal from the balance sheet accelerates that shift and avoids the ongoing cost of maintaining mothballed thermal units at standby readiness.
The carbon market read is less clean. The two plants were on standby, not dispatching, so their permanent removal reduces optionality for the system rather than eliminating active generation. The directional effect on European carbon demand depends on whether, and how often, Civitavecchia and Brindisi had actually been called upon in recent months — data the available reporting does not provide. What the closure does eliminate is the option to re-dispatch them quickly if gas markets tighten again.
That optionality loss is the cleaner market implication. Italy's prior stance — retain the plants, revisit if gas spikes — gave the grid a hedge against exactly the supply disruption scenarios that drove TTF to extreme levels in 2022. If ICE Endex TTF front-month pushes materially above EUR 70/MWh again, Rome will have fewer levers available than it did six months ago.2
Alongside the coal decision, Prime Minister Georgia Meloni is pursuing a reversal of Italy's four-decade nuclear ban, betting that energy security concerns and elevated power prices will sustain public support for restarting a domestic nuclear programme, according to E&E News.3 The two moves are not formally linked, but together they sketch a generation policy that is shedding thermal backup before its replacement capacity is confirmed.
The immediate signal to track is the formal authorisation itself. Wednesday's (2026-08-05) announcement described closure as "imminent," but the energy ministry has not published a specific date or document. Italy reversed course on coal twice inside a single parliamentary session — once to retain the plants in May (2026-05-19), and now to close them in August (2026-08-05). The formal decommissioning order, not a ministerial statement, is what grid planners and adequacy modellers need before updating their assumptions. Until that paperwork is published, standby remains the legal status of both plants regardless of what Rome declared on Wednesday (2026-08-05).5
