Levy Exemption Certificates
Under a separate UK scheme, non-domestic end users of energy (as opposed to the suppliers of energy as in the ROC scheme) are required to pay a Climate Change Levy (CCL) of £4.30 per MWh of energy purchased and consumed, or purchase renewable electricity instead of paying the levy. They can also purchase Levy Exemption Certificates (LECs) rather than the physical power; the certificates are evidence of electricity supply generated from qualifying renewable sources that is exempt from the Levy. The LECs can be redeemed to suppliers, and then in turn to OFGEM, to demonstrate the amount of electricity supplied to non-domestic customers that is exempt from the Levy.
