Jersey Electricity will hold its prices through the winter before introducing a 2.5% rise in March.
The company said it had again delayed an increase until after the colder months, when electricity use is generally highest.
From 1 March 2027, the change will add just over £1 a week for a typical all-electric home using around 10,000 units a year. The impact on individual bills will depend on usage and meter type.
Jersey Electricity chief executive Chris Ambler said: “We know that any increase in household costs is unwelcome, so we have worked hard to keep this rise below the Island’s current rate of inflation.”
Jersey’s latest retail price inflation figure is 3%.
The announcement comes as the company delivers its £120 million Big Upgrade, the largest programme of network investment in its history, to prepare the electricity system for future demand.
Mr Ambler said: “We are acutely aware of the pressures many Islanders continue to face.”
He said the company had a responsibility to find efficiencies and keep prices affordable while making long-term investments in a reliable network.
Alongside the infrastructure work, Jersey Electricity has secured a new four-year supply agreement with French energy company EDF, starting in January 2028.
The deal will give it greater flexibility over how and when it purchases electricity as demand changes. Most of Jersey’s electricity comes from nuclear and hydroelectric sources in France, supported by local back-up generation.
The company said independent comparisons showed its proposed tariff of 24.82p per kilowatt-hour would be approximately 17% below comparable UK household electricity prices and around 3% below the EU average.
