70 -- INTEGRATED SUITE OF SOFTWARE TO PLAN OPERATION OF POWER SYSTEM DUE 060199 POC Christopher Ungate, e-mail: cdungate@tva.gov The Tennessee Valley Authority (TVA) is requesting proposals for information planning purposes only, to identify firms that are the most qualified to provide TVA with an integrated suite of software programs for planning the operation of the TVA power system. This is NOT a Request For Proposal and no award will be made as a result of this Request for Information (RFI). The results of this RFI may or may not result in a RFP. Responses to this RFI will be utilized to determine recipients of future RFPs. TVA maintains and operates a variety of software tools for load forecasting, production costing and simulation, maintenance planning and scheduling, transmission planning, bulk power trading, market price forecasting, and associated decision and financial analyses. The planning horizon for these models is the next day to the next 25 years. This project will replace these models with an integrated set of models supported by a single vendor. These models would share a common database, and model outputs andinputs would be easily transferred between applications. Training and software support would be provided by a combination of TVA and vendor personnel. The models and database must be able to access information from existing TVA systems, such as the Energy Management System (EMS), corporate financial system, reservoir operations system, and other databases. The total number of users of the system will be more than 50 and fewer than 100. Data will be accessed and updated from multiple locations. The total number of concurrent users will be as many as 50. The system must be Year 2000 compliant. Please direct all responses to Christopher Ungate, e-mail address is cdungate@tva.gov Posted 05/17/99 (W-SN332260). (0137)
