Supporting the externality of intermittency in policies for renewable energy

摘要: Abstract We analyse the joint problem of supporting renewables and resource adequacy in a liberalised electricity market present detailed model-based comparison two alternative policies. undertake this context British market. show how, ceteris paribus, the progressive replacement coal with wind imposes extra costs reserve evaluate way to meet this, whether through capacity payments funded by customers, or reliability requirement on generators with capital cost energy feed-in subsidies. consider reality concentration extent which pragmatic regulation could allow prices rise above marginal reduce direct subsidies complex designs. We also evaluate the implied carbon reduction wind, when the security is maintained extra peaking gas. find that support capital allowances rather than more efficient.
