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.


We are responsible for the operation of the Northern Ireland Sustainable Energy Programme (NISEP - formerly the Energy Efficiency Levy).  We also have statutory responsibility for three renewable schemes: the Climate Change Levy (CCL) scheme, the Northern Ireland Renewable Obligation (NIRO) and also the issuance of Renewable Guarantees of Origin Certificates (REGOs – used for Fuel Mix Disclosure purposes).  Both the NIRO and REGO schemes are operated via an agency services agreement with OFGEM. 

Further information on these programmes and schemes can be found in our projects section and within the retail and social publication section.
