Through an extensive information-gathering process, Colorado Springs Utilities staff developed ten portfolios of different resources and investments to represent possible futures for the Colorado Springs electric system. Planning to address key risks and changing regulations while maintaining reliable, affordable electricity is essential.

The ten portfolios display key differences driven by two major factors:

  • Levels of renewable energy and energy efficiency investments;
  • Actions taken at the coal-fired Drake Power Plant to comply with future federal ozone and carbon regulations, which include installing pollution controls (to address ozone), and retiring or reducing the use of key coal-fired units (to address carbon).

Through the Electric Resource Plan process, Colorado Springs Utilities evaluated many issues, and has honed in on three final portfolios. Portfolio H – one of the three finalists – would provide important benefits, including putting the utility in a strong position to comply with federal pollution regulations and transition to cleaner energy, and improving public health and the environment. The background brief outlines the key differences between the portfolio mixes under consideration, and the benefits Portfolio H offers.
