The Department of Energy’s Office of Electricity has initiated a $60M program to conduct long-range transmission planning within the Western, Eastern and Texas Interconnections. As a result of this project, planners will assissted in:
- Siting of new power plants
- Planning expansion of transmission capacity
- Expanding utilization of renewables
- Incorporating environmental concerns into planning process
Western Interconnection Energy-Water Planning Study Led by Sandia National Laboratories
Support for this effort is led by Sandia National Laboratories and is supported by Argonne National Laboratory, Electric Power Research Institute, Idaho National Laboratory, National Renewable Energy Laboratory, Pacific Northwest National Laboratory, and the University of Texas. Objectives include:
- Develop an Energy-Water Decision Support System (DSS) to enable planners in the Western and Texas Interconnections to analyze the implications of water stress for transmission and resource planning.
- Pursue the formulation and development of the Energy-Water DSS through a joint collaboration among the proposal team and the Western Electricity Coordinating Council (WECC), Western Governors’ Association (WGA), the Electric Reliability Council of Texas (ERCOT).
- Use the Energy-Water DSS to investigate water stress implications of the transmission planning scenarios put forward by WECC, WGA, and ERCOT.
Data from Energy-Water Decision Support System (DSS) Tools Informs Decision Maker
The data, models, scenario analyses, and insights derived from this effort will provide a significantly improved body of evidence for policy and decision making at local, state and federal levels, including:
- Industry Planners,
- State and Federal Policymakers, and
In addition, this project will supplement interconnection-wide transmission planning studies with information on water availability, which is critical in shaping electricity generation options.
