Supply Price Controls

A core function within the UR is to set price controls for regulated businesses. These price controls constrain how much of its costs the regulated businesses can pass through to their customers. In the domestic electricity and gas domestic and small I&C markets, we set price controls for the incumbent suppliers, Power NI, firmus Energy Supply (Ten Towns) and SSE Airtricity (Greater Belfast).

These companies submit their proposed costs for running the business to the UR.  These costs are scrutinised by us and the appropriate cost level approved. We also set the profit margin i.e. the level of profit which they are allowed to make from their price-regulated customers.  This covers domestic customers and small business customers using less than 2,500 therms per annum in gas and domestic customers for Power NI. The latest price control documentation can be found below.
