Regional Energy Deployment System (ReEDS)

The Regional Energy Deployment System (ReEDS) is a long-term capacity-expansion model for the deployment of electric power generation technologies and transmission infrastructure throughout the contiguous United States.

ReEDS is designed to analyze critical issues in the electric sector, especially with respect to potential energy policies, such as clean energy and renewable energy standards or carbon restrictions. ReEDS provides a detailed representation of electricity generation and transmission systems and specifically addresses a variety of issues related to renewable energy technologies, including accessibility and cost of transmission, regional quality of renewable resources, seasonal and diurnal load and generation profiles, variability and uncertainty of wind and solar power, and the influence of variability on the reliability of electric power provision.

Key questions addressed:

  • What is the impact of integrating renewable technologies into the power grid on electricity prices?
  • How will the variability and uncertainty of output from wind and solar impact the operation and reliability of the energy system?
  • How can R&D investments impact the market penetration of renewable power systems and other electric-sector technologies?
  • What is the impact of clean energy strategies, renewable portfolio standards, carbon cap and taxes and transmission siting restrictions?

Sample data inputs:

  • Annual electric loads
  • Fuel price supply curves
  • Demand projection
  • Expected price of electricity
  • System boundaries
  • GIS data of energy resources

Sample quantitative outputs:

  • The amount of generator capacity
  • Annual generation from each technology
  • Storage capacity expansion
  • Transmission capacity expansion
  • Total electric sector costs
  • Electricity price
  • Fuel prices
  • Carbon dioxide (CO2) emission
