In this paper, we study the problem of long-term capacity adequacy in electricity markets. Two investment incentive mechanisms, Capacity obligations and Reliability contracts, are analyzed and compared to the benchmark design, the energy-only market. We use the dynamic programming method and...

The German electricity market has recovered well from the 2022 energy crisis. Policymakers should now redirect the focus of energy policy to further expanding renewable energy sources. The year 2023 showed that the German electricity supply remained secure following the shutdown of nuclear power...

Der deutsche Strommarkt hat sich gut vom Krisenjahr 2022 erholt. Die Energiepolitik sollte sich nun wieder auf den Ausbau erneuerbarer Energien fokussieren. Das letzte Jahr hat gezeigt, dass die Stromversorgung auch nach Abschalten der Kernkraftwerke sicher ist. Den Stromverbrauch durch 80...

We model the Spanish wholesale market as a multiplant linear supply function competition model. According to the theory, the larger generators should have supply curves for each plant which are to the left of the supply curves of plants owned by smaller generators. We test this prediction for...

The paper has two major contributions to the theory of repeated games. First, we build a supergame oligopoly model where firms compete in supply functions, we show how collusion sustainability is affected by the presence of a convex cost function, the magnitude of both the slope of demand...

In this paper we check whether generators' bid behavior at the Spanish wholesale electricity market is consistent with the hypothesis of pro?fit maximization on their residual demands. Using OMEL data, we ?find the arc-elasticity of the residual demand around the system marginal price. The...

This paper uses a bi-level game to model markets for delivery of electrical power on looped transmission networks. It analyzes the effectiveness of an independent system operator (ISO) when generators (and, in some cases, retailers) with market power bid a single parameter of their linear supply...

Regulators and market participants have become increasingly concerned about the Spanish electricity tariff deficit due to its size and the difficulties to control its growth. The deficit can be traced to inefficiencies in market organization and solutions should be designed to mitigate those...

The fundamental change of energy policy in Germany (the so-called Energiewende) has lead to a discussion how the security of electricity supply will be affected by the heavily subsidised expansion of electricity generation from renewable energies, as electricity generation from renewable...
