ERSE publishes the 2025 Report on Trends in Average Billed Prices and Markups in the Retail Electricity Market
28/10/2026
ERSE – the Energy Services Regulatory Authority – has published the second edition of the Report on the Evolution of Average Billed Prices and Markups in the Retail Electricity Market, which outlines the quarterly trends in prices and markups in the retail electricity market for the period between 2021 and 2025.
The publication of this Report forms part of ERSE’s market supervision and monitoring activities and aims to promote transparency in the retail electricity market.
The trend in the average final price in the retail electricity market over the last five years, as well as that of its components, has been characterised by significant volatility, with prices fluctuating both upwards and downwards. In 2022 and 2023, the reduction in the Network Access Tariff (TAR), which turned negative in some quarters, mitigated, or even reversed, the price increases in the energy component recorded during the same period.
In 2024, following a few quarters of stabilisation, the upward trend in prices resumed and continued until the first quarter of 2025. In the last three quarters of 2025, average prices returned to lower levels due to a reduction in the costs of the energy component, particularly in the second quarter of the year.
The report shows that, in 2025, 83 per cent of the large-scale customer segment and 46 per cent of industrial customers procured all their energy on the free market under market-indexed contracts. At the other end of the spectrum, domestic customers procured 98 per cent of their energy on the free market at a fixed price. Consequently, larger customers are exposed to greater price volatility; by contrast, the contribution of TARs to the final price is lower.
An analysis of the commercial offers available throughout 2025 for standard low-voltage customers (including domestic customers and some small businesses) shows that, in every quarter, there is a wide variety of offers with prices below those of the regulated market. Consumers have access to offers on the market that allow them to benefit from considerably lower prices; it is therefore important for all customers to regularly check the offers available for signing up to, in particular by using simulators and comparison tools for commercial offers, such as ERSE’s price simulator.
ERSE also publishes a Commercial Offers Bulletin every quarter, containing information on the offers available to standard low-voltage customers, and provides an energy price simulator to help consumers compare options.
