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. Every two years, utilities are required to update integrated resource plans to reflect changing needs and available information. The last IRP was completed in 2017.
