Obligation Levels

Renewables Obligation - Confirmation of Obligation Level for Northern Ireland Suppliers

The Northern Ireland Renewables Obligation, known as the NIRO, is the Department’s main means of increasing renewable electricity generation in Northern Ireland. The NIRO works in tandem with Renewables Obligations covering the rest of the UK. It obliges electricity suppliers to produce a certain number of certificates - known as ROCs - as a proportion of the amount of electricity which they supply to their customers in Northern Ireland.

Alternatively, instead of producing these certificates, suppliers may choose to make a payment to Ofgem (the body which administers the NIRO on behalf of the Department).

Article 12(4) of the Renewables Obligation Order (Northern Ireland) 2009 requires the Department to publish the level of a forthcoming Obligation period six months in advance of its commencing.
