Energy Integrated Resource Plans

Energy Integrated Resource Plans

Public Workshop
Wednesday, August 28, from 6-8 p.m.
Conservation and Environmental Center, 2855 Mesa Road
This is the first in a series of public workshops designed to inform customers about the IRP process and gather input about the types of energy resources they want to power their homes and businesses in the future. The first workshop will cover the following topics and more:
  • Newly adopted Energy Vision and its supporting pillars
  • Transformation of the electric industry
  • IRP process and timeline 
  • IRP goals and targets


Planning is integral to everything we do. It is especially important in determining how we meet the future energy needs of our customers. At the core of this work is our Electric and Natural Gas Integrated Resource Plans (IRPs) that support our Energy Vision and its strategic pillars – Economic, Environment, Resiliency and Innovation.

Our energy IRPs are a roadmap to meet forecasted energy demand using both supply and demand side resources to ensure resilient, reliable and cost-effective energy that is environmentally sustainable.

We are required to conduct an IRP once every five years for purchasing federal hydroelectric power from the Western Area Power Administration. The reasons for updating it now are to determine replacement generation and transmission needs prior to the decommissioning of the Martin Drake Power Plant and the dynamic state of the industry. This transformation includes rapid technological advances, changing market conditions and customer preferences and regulatory drivers.

In addition to a great deal of research, planning and forecasting, customer engagement in the development of our IRPs is important.

As we develop our 2020 IRPs, community input will take place through our Utilities Policy Advisory Committee. We encourage our customers to take part in the process by attending a monthly UPAC meeting, attending an upcoming public workshop or emailing us.

Distribution of findings, including final recommendations, will be presented to our Utilities Board and community owners by late summer 2020.
