Of the light-duty vehicles registered in Platte River’s service territory, 0.4% are EVs, nearly twice the Colorado state average, according to the 2018 City of Fort Collins’ EV Readiness Roadmap. Ultimately, EV energy usage could reach 60 GWh per year by 2026, and peak demand for EV charging may be as much as 99 MW (assuming all vehicles are charged simultaneously).[1]

About the study

To better understand the effect of clustered EV adoption on the distribution system, Platte River is conducting an EV distributed charging study to evaluate vehicle energy consumption patterns and test smart charging technology. The study will be the first large-scale residential smart EV charging initiative in Colorado, serving Platte River’s owner communities of Estes Park, Fort Collins, Longmont and Loveland. Data collection and analysis from up to 300 charging load monitoring and control devices will focus on:

  • EV charging load profiles over a one-year period
  • Usage patterns during 15-minute intervals
  • Resource and cost impact
  • Demographic information
  • Survey satisfaction and interest in participating in later study phases with active control

Participation requirements

EV owners interested in participating in the study must meet the following requirements:

  • Have utility service in Estes Park, Fort Collins, Longmont or Loveland
  • Have or will acquire 50 amp/240-volt service
  • A WiFi connection
  • Agree to the rebate terms and conditions

Purchasing your charger

We are currently making modifications to the Efficiency Works Store and expect to offer instant rebates on smart level 2 chargers to eligible customers in late spring 2020.

Contact us with questions about the study or to be notified when EV chargers are available for purchase from the Efficiency Works Store
