Who is responsible for obtaining transmission services for an interchange transaction?

The Primary Scheduling Entity (PSE) is responsible for obtaining transmission services for an interchange transaction. This role is critical in ensuring that the necessary arrangements are made for the transfer of electrical energy between different entities. The PSE coordinates the scheduling of the transaction and secures the necessary transmission capacity to facilitate the movement of power, making it essential for maintaining the reliability and efficiency of the electric grid.

By securing transmission services, the PSE effectively acts as the interface between the market participants and the transmission infrastructure, ensuring that all regulatory and operational requirements are met. This role is particularly important in a complex power market, where multiple transactions can occur concurrently, and reliable operation of the grid hinges on well-coordinated scheduling.

In the context of electric power transactions, the Balancing Authority (BA) focuses more on maintaining the balance between supply and demand within a defined area and managing generation dispatch. The Transmission Service Provider (TSP) is responsible for providing the actual transmission services but does not initiate the scheduling of those services for interchange transactions. The Federal Energy Regulatory Commission (FERC) oversees regulatory matters and does not directly engage in the transactional aspects of power transfer. Thus, identifying the PSE as the responsible party highlights the distinct roles within the industry and clarifies
