Renewable Energy certificates (RECs) are an electronic form of currency created by the renewable energy Act 2000.(also known as RET Scheme). One REC is equivalent to one megawatt hour of electricity generated by solar PV system. The price of RECs are based on market conditions.
Assign your RECs to a registered agent in exchange of financial benefit which may be in the form of upfront discount or delayed cash payment.
Create RECs by yourself by finding a buyer and then sell them in RECs registry.
