NIROCs
NIROCs are available for every MWh (1000kWh) of accredited renewable generation.
Ofgem administer the process of accrediting and issuing NIROCs.
This year the government have introduced double ROCs whereby all electricity generated after the 1st April 2009 by generating stations with a capacity of up to 50kw will now receive 2 NIROCs per MWh.
This means that generators who produce their own renewable energy will now see return on their investment within a shorter period.
From October 2009, NIE Energy pays £41.60 per NIROC therefore double ROCs will equate to £83.20 per MWh.
You can either opt to appoint NIE Energy to act as your Agent and receive payment based on each kWh of generation or carry out the administration yourself.

If you opt to carry out your own Ofgem / ROC administration
For Ofgem to accredit your renewable technology you must complete the appropriate Ofgem registration. To do this you must register and apply online at https://www.renewablesandchp.ofgem.gov.uk/.
You can find a user guide here.
You will need to have a suitable meter installed to measure generation. If you do not have a suitable meter you should contact your installer who can arrange this for you. If you already have a generation meter installed please click here to ensure it is Ofgem approved(

Receiving payment for ROCs
Ofgem will require you to read this meter on a set date each month or year and submit the reading to Ofgem. Ofgem round up 500kWh to 1 NIROC and less than 500kWh is rounded down.
Ofgem will credit your NIROC account with the appropriate number of NIROCs, and once these are transferred to NIE Energy NIROC account, NIE Energy will send you a bank transfer for the appropriate amount (usually July).
For larger generators who submit monthly readings to Ofgem, a quarterly transfer of NIROCs to the NIE Energy NIROC account will take place and a bank transfer for the appropriate amount arranged.
