Planning for the Future

You and more than 1.4 million Washington homes and businesses depend on us each day for safe, reliable energy service. To meet all of your needs, we must have plentiful supplies of natural gas and electricity available at all times, as well as a plan to address the growth the region is expecting.

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, given what we know today about the future. We know these forecasts will change as the future unfolds and conditions change.

The IRP is an exhaustive, research-based examination of the potential risks and opportunities we face in procuring future energy supplies which:

  • 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 and demographers (with input from expert consultants) develops a new IRP.
