CLP customers are welcome to buy our newly launched Renewable Energy Certificates# to support the local renewable energy generation. Each unit of electricity carried 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 Power. The Renewable Energy Certificates are introduced to offer an alternative way for our customers to take part in local renewable energy development.
