W hat is the Purpose of the
IRP Document?
An IRP is a planning document that outlines how a utility plans to meet its energy and capacity needs, policies and regulations, physical and operational constraints, and
other priorities.
The City’s 2023 IRP will serve as a 20-year blueprint for ensuring reliable and environmentally-responsible
energy, at competitive and affordable rates.

Planning, Analysis, & Modeling Community Stakeholder Outreach • Understanding the priorities and concerns of
customers and stakeholders was crucial in
developing the IRP.
• VPU created a website, held in-person
meetings, and circulated an electronic survey.
• Customers made their top 2 priorities very
clear—reliable service and affordable rates.
• VPU contracted Ascend Analytics to assist
w ith utilizing forecasts, data modeling, and
developing a comprehensive strategy and an
optimal portfolio.
• The 2023 IRP is designed to smoothly
transition and address the goals and targets
outlined in the 2018 IRP to ensure the utility can
successfully meet the aggressive state energy
policies set by 2045.
