Wholesale Electricity Markets with High Shares of Renewable Energies: Effects of Uncertainty on Prices

摘要

Hypothesis 1: Available information and strategic behaviour are intimately relatedHypothesis 2: under supply uncertainty and low demand (high market power)1. Monopoly case: Lower Price under SUPPUNC2. Otherwise: no price difference detectedHypothesis 3: We do not find any difference for demand uncertainty.In summary: “Local” or “temporal” market power due to randomness associated with renewables may not be a problem with a sufficient degree of intransparency. Adaptation of REMIT may be counterproductive.
