The AWEA Utility Integrated Resource Plan (IRP) Database provides details on electric utility IRPs filed in the United States since the beginning of 2015. The database focuses on planned capacity additions, planned coal retirements, cost assumptions, and capacity factor assumptions.

The database helps users to understand which electric utilities across the country are actively planning to add renewable energy, and wind energy specifically, to their generation portfolios in the next 10 to 20 years. Users can also compare cost assumptions across electric utilities, serving as an aid in IRP proceedings.

Key database items include:

  • Wind capacity additions
  • Solar additions
  • Other renewable energy additions
  • Coal retirements
  • Capital cost assumptions for wind, solar, and natural gas
  • Levelized cost of energy (LCOE) assumptions for wind, solar, and natural gas
  • Wind capacity factor assumptions

An IRP is a long-term plan outlining an electric utility’s resource needs to meet future electricity demand. Currently, 33 states require utilities to file IRPs with their state public utility commissions. IRP requirements vary by state, but generally address resource needs for a 20 year planning horizon, with updates made every two to three years.

New IRPs will be added to the database on a quarterly basis.
