This document discusses electric vehicles and related efforts. It outlines the benefits of electric vehicles, including addressing global oil shortages, environmental concerns, and US energy security. It then describes the characteristics of plug-in hybrid electric vehicles and battery electric vehicles, including their electric driving ranges. The document proceeds to discuss Colorado Springs Utilities' efforts to install electric vehicle charging stations and educate customers. It also notes the utility's participation in federal working groups to plan for electric vehicle integration and a smart grid future.

4. Electric Vehicles Characteristics
 Plug-in Hybrid Electric Vehicles
Powered by two energy sources: battery and
an internal combustion engine
Electric driving range: 12-60 mi (unlimited
overall range)
Eg: Chevy Volt, Toyota Prius Plug-in, Fisher
Karma
 Battery Electric Vehicles
Powered 100% by battery energy
Electric driving range: 100-300 mi
Eg: Nissan Leaf, Tesla Roadster, BMW

5. Efforts at CSU
 CSU – Nor’wood Development partnership
 Installation of EV charging stations in Colorado
Springs service territory
 Development and communication of customer
marketing material and education on the benefits of
electric vehicles
 Collection of data on charging station usage to
better understand demand on distribution system
 On-going industry research and active participation
in federal working groups (SGIP) for future planning

6. Efforts at the Federal Level
How do we transition from our current state to the envisioned future
state?
Initial State Envisioned Future State
Passive charging control Smart charging and
that would lead to “dumb discharging in an intuitive
charging” and blown out and transactive grid that is
transformers ubiquitous, highly reliable
and secure
Smart Grid Interoperability Panel (SGIP) initiated by the US NIST is
developing a framework for a staged evolution of all key areas within
the PEV industry
