Sell your electricity

At Power NI we have arrangements in place where we can purchase exported electricity (electricity you generate but don't use on the premises) and NIROCs (Northern Ireland Renewable Obligation Certificates) on electricity which is generated by a renewable source. These arrangements are called the Power NI Microgen. We can only offer these arrangements in Northern Ireland.

 

Benefits of selling back

  • Generate an income
  • Free electricity
  • All in one solution
  • Environmentally friendly

Power NI changes to Micro Generation Tariff application process

Power NI are no longer acting as agent between the generator and Ofgem, to seek accreditation under the Northern Ireland Renewables Obligation (NIRO) to be awarded “ROCs” for eligible generation.

Power NI will continue to offer terms for the purchase of export electricity and associated ROC certificates claimed by the generator directly from Ofgem. Generators will have to apply to Ofgem directly themselves in order to seek accreditation under NIRO and claim the Renewable Obligation Certificates (ROCs) under the scheme.

Ofgem has provided a useful guide to this process available here, which is aimed at generators who may be unfamiliar with how to apply for accreditation and ROC support under NIRO. Unfortunately Power NI will be unable to provide advice on getting accredited.

 

How it works

Northern Ireland Renewable Obligation Certificates (NIROCs)

The Renewables Obligation is the main support scheme for renewable electricity projects in the UK. It places an obligation on UK suppliers of electricity to source an increasing proportion of their electricity from renewable sources. A Renewables Obligation Certificate (ROC) is a green certificate issued to an accredited generator for eligible renewable electricity generated within the United Kingdom. One ROC is issued for each megawatt hour (MWh) of eligible renewable output generated. The Renewables Obligation (Northern Ireland) Order came into effect in April 2005 and the Northern Ireland Renewables Obligation (NIRO) was introduced by the Department for Enterprise, Trade and Investment (DETI).

The NIRO has been subject to regular reviews and the day to day functions of administering the NIRO are performed by Ofgem. Based in London, Ofgem is responsible for the process of accrediting renewable energy installations and issuing Northern Ireland Renewable Obligation Certificates (NIROCs) to generators.It is the owner of the generating station's responsibility to apply for and manage their own Ofgem accreditation.

Export

Because any electricity that is generated but not used can’t be stored, it is exported back to the grid. We will pay you for the amount you export. For renewable energy generators up to 50kW, we will publish our prices for export in October each year, helping you to work out the expected income you can earn for the year ahead.  

Current prices

Power NI Generation tariff rates 2015/2016

Power NI’s Generation Tariff currently offers an annual fixed price for ROCs and export for generators up to 50kW.

Annual ROC and Export prices are approved by the Utility Regulator each year. The ROC price is subject to fluctuation each year due to market factors. The ROC price for 2015-2016 is lower than last year mainly as a result of lower ROC prices in the UK ROC market during the last 12 months as well as a lower ROC price forecast. The export price for 2015-2016 has reduced due to the continued reduction in wholesale fuel costs.

 

Tariff from 1 October 2015 – 30 September 2016

 
1 ROC for agent generators up to 50kW 3.91p/kWh
1 ROC for non agent generators £40.61/MWh

Grid connection

You must have a Grid Connection Agreement in place with NIE Networks in order to export to the electricity network. You can request an NIE Networks Generator application pack (G83/G59) via their website.

An import/export meter must be fitted by NIE Networks , NOT Power NI. If you need this meter this will be triggered by your installer completing and submitting the NIE Networks Grid Connection Agreement. They will then contact you directly to arrange an appointment to change your electricity meter.

 

Export

Export payments will be paid annually. Payment for export will be made by Power NI directly into your bank account; it will not appear on your electricity bill. A meter reader will continue to read your electricity meter so that a bill can be issued for the amount of electricity you have bought from your supplier. We will contact you to request the export meter reading at the end of each September. When we receive a valid export meter reading, we will arrange payment for you.

To learn how to read the most commonly installed meters click here to download our guide or you can watch the video below.

How to read you import/export meter

Renewable Obligation Certficates (ROCs)

If Power NI is acting as your Agent:

Ofgem insist that generation meter readings are taken on the 31st March each year so we will send you a reminder to ask you to take your generation meter reading at the end of March. Power NI will then send all the generation meter readings together to Ofgem at the end of May. ROCs are usually issued by Ofgem from July and Power NI will then arrange a bank transfer for the appropriate amount to all Agent customers. Payment cannot be arranged until the ROCs have been issued.

For customers completing your own Ofgem/ROC administration you are responsible for accrediting and managing your generator with Ofgem. Click here for more information. When you have entered into a contract with Power NI to purchase your export and ROCs, we will contact you to explain how to transfer ROCs from your own Ofgem account to Power NI's account. We can then arrange payment.
