Photo of transmission line SPP’s Transmission Services team creates stakeholder value by evaluating impacts from requests to transmit electricity across segments of the regional power grid. Our assessments help utilities determine whether to invest in the Integrated Marketplace as a hedge against higher prices resulting from congestion. Additionally, we work with organizations in other regions to ensure the efficient and cost-effective flow of power across adjoining transmission systems.
