Abstract: While local distribution companies (LDCs) are responsible for the
procurement and delivery of natural gas to their customers, regulators oversee
the retail pricing of natural gas. 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
