Title
  • On investment decisions in liberalized electricity markets : the impact of price caps at the spot market
Author
  • Gregor, ZOETTL
Physical Description
  • preprint
Notes
  • We analyze the impact of a uniform price cap at electricity spot markets on firms investment decisions and on welfare. Since investment decisions for those markets are taken in the long run, fluctuating demand at the spot market eventually gives rise to high price spikes in case of binding capacities. Those price spikes are considered to send accurate signals for investment in generation capacities, limiting those spikes by price caps is thought to reduce firmsÕ investment incentives. We are able to show that this is not tre for the case of strategic investment behavior. More specifically we analyze a market game where firms choose capacities prior to a spot market which is subject to fluctuating or uncertain demand. We derive, that appropriately chosen price caps do always increase firms investment incentives under imperfect competition. We furthermore characterize the optimal price cap. Based on the theoretical framework, we empirically analyze the impact of uniform price caps on the German electricity market.
