Long-term price and environmental effects in a liberalised electricity market

This paper studies the effects of endogenous investment decisions in a liberalised electricity market on prices and the environment in the time horizon 2000¿2050. Therefore, a computational, game-theoretic, recursive dynamic model is developed. Simulations with the model indicate that perfect competition leads to lower prices and benefits the environment in the form of lower acid and smog emissions. Continued exercise of market power leads to postponed investments and more diversity in the technology portfolio, while under perfect competition there is an earlier switch to gas-based technologies
