Spanish power companies offer fixed electricity rates for up to 10 years
Major electricity companies in Spain are offering contracts that keep the price of electricity used fixed for several years.
Endesa has introduced plans lasting three and five years, while Iberdrola offers a 10-year plan and Repsol a five-year plan.
The fixed price applies only to the energy-use part of the bill, not to charges such as network fees or taxes.
Electricity prices have remained high and volatile, with recent geopolitical tensions affecting natural-gas markets and, in turn, power prices.
These plans are aimed at customers in Spain’s liberalised electricity market, where prices are set by suppliers rather than directly tracking the wholesale market.
A fixed rate can protect customers from price spikes, but it does not remove every source of change in their bills.
The companies are responding to a perceived rise in demand for predictable costs, though the duration of the price uncertainty is unclear.
Spanish electricity suppliers are offering fixed energy charges for periods of up to 10 years.
Endesa has introduced tariffs fixing the energy charge for three or five years, while Iberdrola and Repsol also offer longer-term options.
The fixed-price commitment applies to the energy charge, not other bill items such as network charges and taxes.
Suppliers are responding to concerns about energy-price volatility and demand for more predictable bills.
