The cost of service is the common regulation method but provides arguably little incentive for an LDC to optimally manage procurement activities. Taking variance as a measure of risk, we model and solve the LDC’s procurement problem in face of two linear incentive contracts: the cost based contract, where the LDC’s compensation is linear in the procurement cost and a benchmark based contract, where the LDC’s compensation is linear in the difference between the procurement cost and a preselected benchmark. We conclude that the level of cost reduction effort chosen by the LDC is the same under the two contracts. However, the LDC has less incentive to hedge against price risk and consequently the fee to consumers has a higher variance when a benchmark is used. We argue that using futures
