Strategic Reserves Versus Market-Wide Capacity Mechanisms Open
Many electricity markets use capacity mechanisms to support generation owners. Capacity payments can mitigate imperfections associated with “missing money” in the spot market and solve transitory capacity shortages caused by investment cyc…

Optimal Capacity Mechanisms for Competitive Electricity Markets Open
Capacity mechanisms are increasingly used in electricity market design around the world yet their role remains hotly debated. This paper introduces a new benchmark model of a capacity mechanism in a competitive electricity market with many…

Central- versus Self-Dispatch in Electricity Markets Open
In centralized markets, producers submit detailed cost data to the dayahead market, and the market operator decides how much should be produced in each plant. This differs from decentralized markets that rely on self-commitment and where p…

Increase-Decrease Game under Imperfect Competition in Two-stage Zonal Power Markets Part II: Solution Algorithm Open
In part I of this paper, we proposed a Mixed-Integer Linear Program (MILP) to analyse imperfect competition of oligopoly producers in two-stage zonal power markets. In part II of this paper, we propose a solution algorithm which decomposes…

Increase-Decrease Game under Imperfect Competition in Two-stage Zonal Power Markets Part I: Concept Analysis Open
This paper is part I of a two-part paper. It proposes a two-stage game to analyze imperfect competition of producers in zonal power markets with a day-ahead and a real-time market. We consider strategic producers in both markets. They need…

Simulation and Evaluation of Zonal Electricity Market Designs Open
Zonal pricing with countertrading (a market-based redispatch) gives arbitrage opportunities to the power producers located in the export-constrained nodes. They can increase their profit by increasing the output in the day-ahead market and…

A minor change in market trading rules could save taxpayers billions of dollars Open
When ties occur at low offer prices, higher priority should be given to sell orders with a large volume, writes Pär Holmberg

Input-Output Analysis of Emissions Embodied in Swedish Imports from China, 1995-2009 Open
With the growth of international trade many researchers are questioning the effects on the environment by emissions embodied in international trade flows. The embodied emissions in the import (EEI) and export of Sweden are relatively unexp…

Electricity markets: Designing auctions where suppliers have uncertain costs Open
We analyse how the market design influences the bidding behaviour in multi-unit auctions, such as wholesale electricity markets. It is shown that competition improves for increased market transparency and we identify circumstances where th…

Price Instability in Multi-Unit Auctions Open
We consider a procurement auction, where each supplier has private costs and submits a stepped supply function. We solve for a Bayesian Nash equilibrium and show that the equilibrium has a price instability in the sense that a minor change…
