Regulatory price control

NIE Networks derives its revenue principally through charges for use of the distribution system and Public Service Obligation (PSO) charges levied on electricity suppliers and charges for transmission services (mainly for use of the transmission system) levied on SONI, the transmission system operator in Northern Ireland.
 
Under its Transmission and Distribution licences, NIE Networks' charges are subject to price controls. There have been five transmission and distribution price controls since the company was privatised in 1993. The current price control (the RP5 price control) runs from 1 April 2012 to 30 September 2017. The next price control (the RP6 price control) will run from 1 October 2017 to 31 March 2024.

RP5

The RP5 price control was determined by the Competition Commission in April 2014 following a referral by the Utility Regulator.  A key aspect of the Commission’s determination is the closer alignment of the regulatory framework and reporting arrangements with those applied by Ofgem (the GB regulator).  NIE Networks fully supports this change which should facilitate future price control reviews.

RP6

For the RP6 price control NIE Networks submitted a detailed business plan - Investing for the Future - to the Utility Regulator in June 2016, setting out the plans we have for the period October 2017 to March 2024.

A detailed review of the plan was carried out by the Utility Regulator and in March 2017 the Utility Regulator published its Draft Determination for RP6. We responded to the Draft Determination on 19 May 2017.
