Small Scale Photovoltaics (SSPV) ROC and Export Payment: Understanding your Proforma Invoice and Remittance

Around this time of year, many of our SSPV customers will have received their annual ROC and Export payment. As part of this process, they will have received an email invoice, containing a full payment breakdown, detailing how the figure was calculated.

These invoices can be confusing, with a lot of numbers and abbreviations, so to help you understand your payment we have put together some key terms to note:

Generating station: The name of you PV installation and how OFGEM refer to your system. They will release ROCs for a ‘generating station’ rather than a client’s name.

Invoice date: The date on which your invoice was generated and sent.

Invoice reference: How we will refer to your invoice in any correspondence and in any future cases where we must refer to a previous payment.

ARET (Action Renewables Energy Trading) contact and phone: Contact information for theSSPV team at Action Renewables.

Account name: Your Action Renewables account name.

ROC payment: For the year given, e.g. 17/18, your ROC payment is for generation between 1st April and 31st March. 

Eligible generation: This is the volume of electricity generated by your PV station in this given time period. Usually this will correlate with your annual meter submissions, made to us each year on 31st March. For example, if your reading on 31/03/2017 was 4000 kWh and your reading on 31/03/2018 was 7500 kWh, your eligible generation would be 3500 kWh. If you did not submit your reading to us on 31st March, your reading will be pro-rated back to this date.

End reading date: This will be the 31st March, which is the end of the ROC generation year. This ROC year is set and cannot be changed, so any ROC payment made will be for generation ending on 31st March.

Unit value: The value of each kWh unit produced. This is derived from the ROC price that Action Renewables attain when trading your ROCs to electricity suppliers. 

Value: Unit value multiplied by the number of Units (eligible generation). This figure is for your ROCs.

VAT @ 20%: Some customers, particularly businesses who are VAT registered can claim VAT on their ROCs, which is currently 20%. For most domestic customers, this will just read £0.

Deemed export payment: Export is paid for the year prior to that of your ROC payment. For example, if your invoice is for 2017/18 ROCs, the export section will be for the 2016/17 period. This is to comply with NIEN and the Utility Regulator. Export is currently calculated using the deemed solution, meaning you get paid export on 45% of eligible generation.

Total deemed export: The number of units for which you will be paid export. This figure will be 45% of your previous year’s total eligible generation. For example, if you generate 1000 kWh in 2016/17, in 2018, you will be paid for 450 kWh of export.

Unit value: The unit value per kWh of exported electricity, as determined by NIEN.

Value: The total value, multiplying the number of eligible units by the unit price.

VAT: Like ROCs, some customers can claim VAT on their deemed export and this figure is stated here.

Total value: The ROC value and the Export value added together. This will be the total payment that Action Renewables make to you and will be paid directly into your bank account.

The ROC and Export invoice provides a comprehensive breakdown of how your payment is calculated and how your generated units are converted to monetary value. We encourage you to analyse this, as it will give you a greater understanding of how the ROC scheme works and explains how you can get the most from your PV system.
