ORD005: Electricity Market Reform

Formal title: Electricity Market Reform

As part of the Electricity Market Reform (EMR) program the Government has introduced two new mechanisms: Contracts for Difference (CfD); and the Capacity Market (CM).

CFDs are designed as an incentive for investment in new low-carbon electricity generation. The CM is designed to ensure sufficient and reliable capacity when there is not enough electricity available on the Transmission System.
