摘要: Abstract The limitations of production subsidies for variable renewable energy (VRE) plant as a means decarbonising electricity markets are well known. Despite this, VRE the most prevalent form policy intervention in Australia. In absence cost-effective storage, can create incentives to produce at times system may not need it, thereby severing link between spot market and financial generate. Such also reduce incentive new participate ‘firm’ forward derivative markets. this paper, we examine two adjustments that could be made would correct these unintended consequences. Firstly, quantum subsidy function wholesale price, demand or emissions; secondly, generators ineligible receive without demonstrating they facilitating supply contracts. effect both increase demand-follow; is, make its output ‘firmer’.
