Arera power and gas tariff trend
Arera power and gas tariff trend
The Regulatory Authority for Energy, Networks and the Environment (ARERA) publishes the update of the economic conditions of the protection services, quarterly for power and monthly for gas.
Periodic Adjustment of Tariffs for Protected Services
Electricity Supply Tariffs
According to ARERA data for electricity, price projections for the fourth quarter of 2025 indicate a 7.6% decrease in the electricity bill for the "typical" vulnerable customer[1] served under the Protected Market. The decrease compared to the previous quarter is mainly due to the reduction in energy costs and dispatching components, which have decreased by 5% and 2.2%, respectively. The balancing component (PPE) also shows a negative variation of 0.4%. The general system charges remain unchanged.
It is reminded that, in implementation of the ‘bill decree’ (art. 1, paragraph 1, decree-law n. 19/25), those with an ISEE up to 25,000 euros will automatically receive the extraordinary contribution of 200 euros, which is cumulative with the social bonus received by households with an ISEE up to 9,530 euros or up to 20,000 euros for large families.
To automatically receive the social bonuses and the extraordinary contribution, it is necessary to submit the Single Substitute Declaration (DSU) by December 31, 2025, and obtain an ISEE certificate within the thresholds set by the regulations.
The expenditure for the typical vulnerable customer in the Protected Market will be approximately 608.72 euros for the period from January 1, 2025, to December 31, 2025, compared to 498.10 euros for the period from January 1, 2024, to December 31, 2024 (+22.2%).
From October 1, 2025, the reference price for electricity for the typical customer will be 28.75 cents per kilowatt-hour, including taxes.
Conditions for Transition to the Gradual Protection Service: From July 1, 2024, all non-vulnerable customers previously served under the Standard Offer regime were automatically transferred to the Gradual Protection Service, with the supplier selected via auction in the relevant area. This transitional service will be active for just under three years (until March 31, 2027), after which, in the absence of an explicit choice, customers will continue to be supplied by the same vendor on the free market.
Updates for Vulnerable Customers: ARERA will continue to monitor and update quarterly the economic conditions of the Standard Offer regime for vulnerable customers, including tariff updates such as those provided by Decree-Law 181/23 on energy security. The typical household has average annual electricity consumption of 2,700 kWh and a committed power of 3 kW.
[1] This refers to vulnerable customers with annual consumption of 2,000 kWh and a committed power of 3 kW. The calculation for the ‘average’ vulnerable customer, with consumption of 2,700 kWh/year and 3 kW power, is available on the Authority's website.

Natural gas supply rates
Starting from January 2024, the gas protection service has been replaced by the vulnerability protection service, intended for domestic customers only vulnerable. ARERA also makes public on its website (for the first time since the end of electricity protection) the fees for the month of July 2024 which apply to non-vulnerable domestic customers included in the Gradual Protection Service.
From January 2024, the Authority, with the same times and methods as in previous months, publish on the site the price component of the gas to cover supply costs, applied to customers of the vulnerability protection service. The component of the gas price to cover supply costs (CMEM,m), applied to customers in the vulnerability protection service, is updated by ARERA as a monthly average of the price on the Italian wholesale market (the PSV day ahead) and published within the first 2 working days of the month following the reference month.
For the month of September, which saw wholesale prices slightly lower than those recorded in August, the price of the gas raw material alone (CMEM,m), for customers in the vulnerability protection service, is equal to 34,89 €/MWh*.
