Ghana's 2026 tariff rises: what they mean for your power bill

Ghana's Public Utilities Regulatory Commission began 2026 with a major tariff review that raised electricity prices by 9.86% across every customer category, effective 1 January. The quarterly mechanism then added a further 3.49% from 1 July 2026. If your business runs on grid power, your costs have been climbing twice a year — and the reasons why matter more than the percentages.

What your tariff is actually made of

The regulator adjusts tariffs each quarter to track a short list of factors: the cedi–dollar exchange rate, domestic inflation, the generation mix, and the cost of natural gas feeding the thermal plants. For the third quarter of 2026 it applied an exchange rate of about GH¢11.22 to the dollar and a gas cost of just under US$8 per million BTU. Two of those inputs — the exchange rate and the price of imported fuel — are set far outside Ghana, by markets you cannot influence.

Why that matters: the generation mix

Ghana's hydro-thermal generation mix stood at roughly 21% hydro and 79% thermal in the quarter under review. In plain terms, about four of every five kilowatt-hours you buy were made by burning fuel priced in dollars. When the cedi slips or gas prices move, that cost arrives on your next bill. The tariff formula makes it official.

The hedge sitting on your roof

A solar array produces electricity with no fuel and no dollar-denominated input. Once the system is installed, its running cost is essentially zero, while every grid unit you avoid buying is a unit no longer exposed to the next quarterly review. Pair the array with storage and you also shift daytime load off the grid and ride through outages without a diesel set — whose fuel is, of course, dollar-priced too.

Doing the maths before the next review

Pull twelve months of bills, note your average cedi per kilowatt-hour and how it moved across the last two reviews, and project that trajectory forward. Then compare it with a fixed, known system price spread over the same period. In most commercial profiles we size, the solar route wins — and every additional tariff increase widens the gap.
