Diagnosing Unilateral Market Power in Electricity Reserves Market
We use information released during the investigation of the California electricity crisis of 2000 and 2001 by the Federal Energy Regulatory Commission to diagnose allocative inefficiencies in the stateâ€™s wholesale reserve markets. Material that has been largely neglected allows us to replicate market outcomes with a high degree of precision for the second and third quarters of 2000. Building on the work of Wolak (2000), we calculate a lower bound for the sellersâ€™ price-cost margins using the inverse elasticities of their residual demand curves. The downward bias in our estimates stems from the fact that we donâ€™t account for the hierarchical substitutability of the reserve types. The margins averaged at least 20 percent for the two highest quality types of reserves, regulation and spinning, generating millions of dollars in transfers to a handful of sellers. We attribute the deviations from marginal cost pricing to the marketsâ€™ high concentration and a principal-agent relationship that emerged from their design.
