Abstract

Among other things, one or more techniques and/or systems are provided for leasing electrical network computational services to one or more network control centers. A power grid may comprise one or more substations. Network control centers disposed within the power grid may be configured to manage the substations within the power grid. A remote centralized network control center may be configured to lease electrical network computational services to the network control centers (e.g., which may mitigate costs associated with including computational hardware and/or software within respective network control centers for performing such electrical network computational services). In this way, substation data received from a network control center may be processed by the remote centralized network control center according to a level of service subscribed to by the network control center. Computational results may be provided back to the network control center (e.g., in real-time).
