Fuel caps and pump price reductions
Fuel distribution companies across Italy implemented price caps following government calls to mitigate energy costs. State-controlled energy firm Eni introduced a 30-day cap on 28 September 2026, setting ceiling prices at 1.99 euros per litre for unleaded petrol and 2.19 euros per litre for diesel at its self-service stations. Data published on 30 September 2026 by the Ministry of Enterprises and Made in Italy showed national average self-service petrol dropping to 2.111 euros per litre from 2.159 euros on Sunday, while self-service diesel fell to 2.316 euros from 2.377 euros. On motorway stations, average self-service rates reached 2.138 euros for petrol and 2.345 euros for diesel, reflecting two-day decreases of 7.4 cents and 7.6 cents respectively. Competitors Italiana Petroli and Q8 Italia matched the price caps across their respective retail networks.

Distributor network participation
Regional and independent distributors followed the price containment initiative across their networks. Padua-based distributor Costantin capped prices across its network of Costantin, IP, and Esso branded stations. The family-owned firm, founded in 1967 and reporting over 1.1 billion euros in revenue in 2025, linked its participation to its partnership with Socar, Azerbaijan's state energy company that acquired control of Italiana Petroli in May 2026. Kuwait-owned Q8 Italia agreed to a 30-day modular cap structure, drawing official acknowledgments from Prime Minister Giorgia Meloni. Independent unbranded stations and supermarket operator Enercoop adjusted retail prices as well, with some unbranded pumps pricing below the corporate caps as supply logistics stabilized.
Utility bill discounts and market offers
Eni expanded its pricing measures to residential gas and electricity through its retail subsidiary Plenitude under the Fixa Time 24 Smart plan. Customers who sign up between 1 October and 24 October 2026 receive a 30% discount on the commodity portion of fixed-rate electricity and gas tariffs, locked in for 24 months. Plenitude estimated the reduction will save a typical household roughly 100 euros per year on electricity and 100 euros on gas, reaching 200 euros annually for dual-fuel subscribers. The company framed the reduction in a corporate statement.
“offers a new contribution to Italian families as part of the Eni for Italy initiative, aimed at supporting citizens in coping with high energy prices.”
Following Eni's announcement, Enel noted that its Digital Luce plan, available since April 2026, already fixes electricity costs at 0.108 euros per kilowatt-hour (108 euros per megawatt-hour) for 24 months. Enel calculated that this rate sits approximately 50% below wholesale prices, delivering over 200 euros in annual savings for an average household consuming 2 megawatt-hours of certified renewable energy. Milan-based utility A2A maintained its ten-year fixed renewable energy contracts, which have enrolled 135,000 households since 2023 and expanded to small and medium enterprises in March 2026.
Protected market tariff increases
While commercial suppliers promoted fixed-price discounts in the deregulated retail market, regulated rates for protected consumers moved upward. National energy regulator ARERA scheduled a 37.3% increase in electricity bills for roughly three million vulnerable consumers remaining in the protected regime (Maggior Tutela), taking effect on 1 October 2026. The increase reflects procurement costs driven by the Middle East crisis, creating a divergence between open-market promotions and regulated prices. Enel stated that 80% of its approximately 11 million retail customers have already chosen fixed-rate contracts, while Eni serves roughly 9 million retail accounts. Minister of Enterprises and Made in Italy Adolfo Urso called on additional energy providers to follow the voluntary price relief measures.
