Looking Forward – Our Questions
What is our unique fingerprint as a community with respect to the environment?
How do we bring together all the diverse stakeholder views and draw out the best ideas in service of a common goal?
What does success look like for Colorado Springs with electric energy in 2020?
Given the challenges we are facing, what portfolio mix best positions us for that success?
A Vision for TomorrowA Starting Place
Draft Vision:
By 2020, Colorado Springs Utilities will provide20% of its total electric energy through renewable sources, reduce average customer use by 10% and maintain a 20% regional cost advantage.

June 2010 Monthly Power Cost – Residential - 600 kWh
Currently 21% lower than average of the other three electric utilities
A Vision for TomorrowConclusionsColorado Springs Utilities has offered
value to citizens for over 85 years:Local ownershipReliable electricityCompetitive costCompliance and beyond with
environmental standardsWe have a unique opportunity to
address the energy challenges ahead in a way that positions our community to thrive
We must maintain the critical balance.
A Vision for TomorrowConclusionsA diverse portfolio continues
to offer the best blueprint for tomorrow
An energy vision can bring us together and be a rallying point for future success
Collaboration and innovation are key to meeting the challenges of tomorrow
We must move forward together as a community, region, and industry to build the future now
