Integrated resource plan

The Integrated Resource Plan (IRP) is a forecast of conservation resources and supply-side resource additions that appear to be cost effective to meet the growing needs of our customers over the next 20 years.

We know these forecasts will change as the future unfolds and conditions change.

 

The IRP:

  • Examines the many energy-resource options available to PSE, including the maximum amount of new energy "supply" we can acquire through energy efficiency

  • Makes a thorough, objective assessment of the benefits, costs and risks associated with each energy-supply option

  • Analyzes the region's population and economic trends, including a forecast of PSE customers' natural gas and electricity needs two decades into the future

  • Evaluates political and economic policies and trends, and their potential impact on energy production, usage and availability

Every two years, a team of in-house economists, energy specialists, environmental advocates, demographers and other experts develops a new IRP.

 

2019 IRP Plan Public Participation

Information and presentations concerning the 2019 public participation process are available below. The Work Plan for the 2019 IRP will be filed with the Washington Utilities and Transportation Commission on or before July 13, 2019. PSE intends to remove the 2017 IRP meeting archive by or before that date, but materials concerning that process will be available upon request.
 
The IRP Advisory Group (IRPAG) and the Technical Advisory Group (TAG) are teams of external stakeholders and regulators who meet to provide input during the integrated resource planning process. Their valuable input helps to guide the development of PSE's Integrated Resource Plan (IRP).
 
The kickoff meeting for the 2019 IRP was on May 30, 2019. The meeting covered team introductions, basic IRP education, ground rules, electric scenarios and sensitives, and system planning.

2017 IRP Advisory Group

Information and presentations for the 2017 IRP Advisory Group meetings are available below. 

The IRP Advisory Group (IRPAG) is a team of external stakeholders and regulators who meet regularly to provide feedback during the integrated resource planning process. Their valuable input helps to guide the development of PSE's Integrated Resource Plan (IRP).

For a more detailed discussion of the role of the IRPAG, see the 2017 IRP Work Plan.

Questions concerning the IRP can be directed to Phillip Popoff, Manager Integrated Resource Planning, phillip.popoff@pse.com, 425-462-3229.
