Buy renewable energy certificates (Residential)

Reduce your electricity carbon footprint with CLP Renewable Energy Certificates.


CLP customers are welcome to buy our Renewable Energy Certificates(REC) to support the local renewable energy generation. Each unit of electricity listed in a Renewable Energy Certificate represents the electricity produced by local renewable energy sources including solar power, wind power and landfill gas projects, generated or purchased (such as through Feed-in Tariff Scheme) by CLP.

The Renewable Energy Certificates are introduced to offer an alternative way for our customers to take part in local renewable energy development. You may refer to the CLP Renewable Energy Certificate (CLP REC) Specification (PDF) for more information.
