The requirement for deregulation and unbundling of services provided by utilities in recent years has become a major pressure in India due to the increase in load demand. This paper presents a new method for allocating embedded cost of transmission to its users by allowing simultaneous bilateral/multilateral feasible transactions under deregulated environment. The effect of reactive power flow caused by the wheeling transaction has also taken into consideration, while allocating embedded cost. The magnitude of feasible wheeling transactions is determined by computing the Available Transfer Capability (ATC) of the test systems. Determination of ATC with margins has been carried in combined economic emission dispatch (CEED) environment. The proposed embedded cost methods have been applied to Indian utility-62 bus system and results obtained are found to be useful in deregulated environment.
