Why REC was introduced?

To address the mismatch between availability of RE resources in state and the requirement of obligated entities to meet RPO, a market based instrument called Renewable energy certificate (REC) was introduced to promote renewable energy and facilitate compliance of Renewable purchase obligation. One REC is equivalent to 1MWh. RECs are further categorized as Solar and Non Solar RECs. Solar RECs are issued to eligible entities who generates electricity based on Solar as RE sources and Non Solar RECs are issued to eligible entities who generates electricity based on RE sources other than Non-Solar.

  • There will be a central level agency to be designated by the Central Commission for registration of RE generators participating in the scheme.
  • The RE generators will have two options - either to sell the renewable energy at preferential tariff fixed by the concerned Electricity Regulatory Commission or to sell the electricity generation and environmental attributes associated with RE generation separately.
  • On choosing the second option, the environmental attributes can be exchanged in the form of REC. Price of electricity component would be equivalent to weighted average power purchase cost of the distribution company including short-term power purchase but excluding renewable power purchase cost.
  • The Central Agency will issue the REC to RE generators.
  • The value of REC will be equivalent to 1 MWh of electricity injected into the grid from renewable energy sources.
  • The REC will be exchanged only in the Power Exchanges approved by CERC within the band of a floor price and a forbearance (ceiling) price to be determined by CERC from time to time.
  • The distribution companies, Open Access consumer, Captive Power Plants (CPPs) will have option of purchasing the REC to meet their Renewable Purchase Obligations (RPO). Pertinently, RPO is the obligation mandated by the State Electricity Regulatory Commission (SERC) under the Act, to purchase minimum level of renewable energy out of the total consumption in the area of a distribution licensee.
  • There will also be compliance auditors to ensure compliance of the requirement of the REC by the participants of the scheme.
