We have today published our Final Determination for Power NI’s 2026-2029 Price Control. The document outlines our decisions on the scope, duration, operating cost allowance and profit margin for the Power NI supply price control, which will commence in April 2025.
Power NI was the first domestic electricity supplier in Northern Ireland and remains the dominant supplier in the market. We regulate the charges that the company can pass on to its customers. This is achieved through the price control and tariff setting processes.
A price control sets out funding decisions on a range of areas, including how much the company can charge consumers to run its business, how the company is going to operate and its level of profit margin.
In coming to our final decisions, we scrutinised and challenged Power NI’s Business Plan and reviewed its cost forecasts.
We then set out our proposed decisions in a Draft Determination that was published for consultation in December 2024 for a 10-week period. Having considered the responses received, we have now published our Final Determination.
Over the four-year period, we have determined that Power NI will receive an allowance of £165 million in operating and other costs. We also determined a profit margin which is equivalent to 2.2% of revenue.
The allowances provided for within this next price control for Power NI make up around 8 per cent of a typical domestic customer’s bill, as of the 1 December 2024 tariff rate.
We have also published a consultation on the proposed licence modifications that will give effect to the decisions in the Price Control Final Determination.
The consultation is seeking views on our proposed licence modifications which will set the duration, scope, operating expenditure allowance and margin for Power NI for the next four years.
It is open until 5:00pm on Friday 23 May 2025 and we would encourage you to make your views known to us.
