Quantifying the Impact of Wind Energy on Market Coupling

In a context of market coupling, we study analytically the impact of wind farm concentration and of the uncertainty resulting from the introduction of renewable energy on the procurement total cost, on the market welfare and on the ratio of renewable procurements to conventional supplies. Markets having incomplete information on the quantities of renewable energy produced by the other markets, we show that the providers have incentives to buy information regarding the variability of the other markets’ productions. Provided this information could be certified and sold by an external operator, we derive analytically the optimal price for such certified information, depending on the required confidence level
