In this paper, a new mechanism is proposed to apportion expected reserve costs between
electricity market agents in the power system. The uncertainties of generation units, transmission lines, wind
power generation and electrical loads are considered in this model. Hence, a Stochastic Unit Commitment

(SUC) is used to apply the uncertainty of stochastic variables in the simultaneous energy and reserve market-
clearing problem. Moreover, electrical customers can participate in the electricity market based on their

desired strategies. In this paper, a novel method is proposed to allocate reserve costs between GenCos,
TransCos, electrical customers and wind farm owners. Consequently, market agents are responsible for
paying a portion of the allocated expected reserve costs based on the economic metrics that are defined for
the first time in this paper. Finally, two cases including a 3-bus test system and IEEE-RTS are utilized to
illustrate the performance of the proposed mechanism to share the expected reserve costs.
