The Energy Market Authority (“EMA”) implemented vesting contracts on1 Jan 2004. The objective of the vesting regime is to enhance economic efficiency in the electricity market by mitigating the exercise of market power by the generation companies (“gencos”). The vesting contracts mandate a specified amount of electricity (viz. the vesting contract level) to be hedged at a specified price (viz. the vesting contract price). This removes the incentives for gencos to withhold their generation capacity to sustain inefficient spot prices in the wholesale electricity market.
The vesting contract price is set based on the long run marginal cost (“LRMC”) of the most efficient generation technology that accounts for at least 25% of the system demand in Singapore. The most efficient technology at present is the F-class combined cycle gas turbine (“CCGT”). EMA reviews and determines the vesting contract price parameters biennially or when necessary in accordance withthe published EMA’s Procedures for Calculating the Components of the Vesting Contracts(“Procedures”). EMA appointed WSP Consultancy Pte Ltd(“WSP”) and KPMGSingapore(“KPMG”) (“Consultants”) to review the LRMC parameters for setting the vesting contract price for 2021 and 2022.
EMA invites comments and feedback on the Consultation Paper and Consultants’ draft reports.
