Power NI
Power NI is the largest electricity supplier in Northern Ireland. It holds a total market share of 55.7% or approximately 455,063 customers.
Power NI has a large mix of both top-up and bill pay customers.
Prior to competition in the energy market, Power NI was the incumbent sole provider. Due to its dominant market position, the supplier continues to be subject to price controls – this requires the Utility Regulator to authorise price changes and enables them to cap the margin (amount of profit) Power NI makes from price-regulated customers.
