    Regional Flow Forecast Tool

    As a result of the Northwest Power Pool Market Assessment and Coordination Initiative efforts and supporting company funding, tools have been developed that provide a forecast of expected near-term flows on a set of WECC flowgates. The forecasts are computed projections of flows based upon current actual flows, generation forecasts, load forecasts and impedence base flow calculations using the system network model.

    Beginning on March 31, 2015, access to production forecasts was available for regional TSP & BA entities.

    Beginning on April 14, 2016, access to production forecasts will be available for all OATT customers of the supporting TSPs to paths included in the displays operated by the respective TSPs. This includes access for market function employees.

    Procedures for requesting access can be obtained from Peak Reliability. A link to the Peak Reliability site containing these procedures is found under the Documents area to the left.
