What are ROCs?

ROCs or Renewable Obligation Certificates are virtual certificates which are managed by Ofgem in London. Ofgem act on behalf of NIAUR – they are responsible for approving each system and issuing ROCs each year.  ROCs are important for Power NI – all electricity suppliers in the UK need to source a portion of their electricity from renewable sources and present ROCs each year.
