The renewable energy sector is key to meeting climate policy targets and threatens the market power of conventional fossil-fuel electricity generators. The intermittence of renewable energy sources complicates environmental policy. This paper justifies to some extent the use of feed-in tariffs, capacity taxes and price caps in addition to emission taxes. Feed-in tariffs or capacity taxes might be necessary to counteract strategic overinvestment in conventional fossil-fuel capacities, but this strategic overinvestment can turn into underinvestment if the costs of renewable energy have sufficiently plummeted and the share of customers on time-invariant pricing schemes is sufficiently large. Emission taxes and feed-in tariffs might increase or decrease, as the costs of renewable energy decline, and the paper identifies the circumstances under which these different outcomes result. The analysis is based on a model in which a conventional fossil-fuel electricity producer competes with a potentially large number of renewable energy generators. The fossil-fuel electricity producer might apply different technologies.
