Increased penetration of wind energy will make electricity market prices more volatile. As a result, market participants will bear increased financial risks, which impact investment decisions and in turn, makes it harder to achieve sustainable energy goals. As a remedy, in this paper, we propose an insurance market that complements any wholesale market design. Our mechanism can be run by any suitable financial entity such as an independent system operator, with the aim of reducing the financial impacts of volatile prices. We provide theoretical guarantees, analytically characterize the outcomes over a copperplate power system example, and numerically explore the same for a modified IEEE 14-bus test system.
