We are an independent non-ministerial government department set up to ensure the effective regulation of the Electricity, Gas and Water and Sewerage industries in Northern Ireland.


Tariff Review
We scrutinise and approve the Power NI tariff review for regulated consumers (under 50 MWh), in consultation with the Consumer Council and Department of Enterprise, Trade and Investment. This is when the maximum price is decided that domestic consumers of Power NI could pay for their electricity.

The most recent regulated electricity tariff review relates to the period from 1 April 2016.  As part of this review Power NI provided detailed information submissions on the various components of its tariffs to the Utility Regulator for scrutiny. These are based on best estimate forecasts of Power NI’s costs. 

Overall, the outcome of the review is that there will be a 9.2% reduction to the Power NI regulated tariffs from the 1 April 2015.

As is the normal process, we will continue to monitor wholesale costs on a monthly basis and will act as appropriate.
