The rising cost of keeping the lights on.
Five straight years of above-inflation electricity rises, and a fixed standing charge that has climbed far faster than the price of the power itself.
Indexed to July 2023 = 100, so the fixed quarterly charge and the per-unit rate can be read on one scale. The standing charge was £30 a quarter before July 2023, so its full rise is larger than this index, which starts a year later, shows.

Above-inflation, every year
The STSB-approved revenue-cap increase for Guernsey Electricity, each July since 2022. In 2024 and 2026 the approval came in below what GEL had applied for.
The July 2025 increase of 8% came against RPI of 4.2%, and drew an organised protest and a petition of more than 1,300 signatures. The 2026 rise of 5% sits against a latest all-items RPI of 4.3%.

Who pays
The fixed charge has outpaced the unit rate
The standing charge is levied per quarter regardless of how much electricity a household uses, so raising it falls hardest on the lowest-using, typically smaller and lower-income, homes.
Since July 2023 the fixed standing charge has risen +81% on the index above, while the unit rate rose 14.9%. Measured from its pre-July-2023 level of £30 a quarter, the standing charge has risen +198%, close to a tripling, to £89.35. Guernsey Electricity has said it knows customers see the recovery method as unfair and that it is committed to reforming it; for 2026 the STSB held the standing-charge rise to 3% and put more of the increase onto unit rates, so that, in its words, households using the least electricity would see the lowest bill increase.

In context
How Guernsey compares
Standard domestic electricity unit rate against Jersey and Great Britain. Reference dates differ (given per bar); standing charges are not included, as they are structured differently between systems.
Ahead of demand
A flat demand line, against a projected near-doubling
Recorded winter peak demand has been broadly flat since 2022, while the case for the network investment behind these bills projects peak roughly doubling by 2050.
Peak demand was 95 MW in 2022 and 85.9 MW in the winter of 2024/25. Guernsey Electricity itself says demand management could hold the 2050 peak to 125 MW rather than 157 MW, saving more than £160m, which is an acknowledgement that the higher figure is not fixed. The dashed lines are the investment case’s projection, not measured data.
