The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Date Enacted:
Columbia Code of Ordinances, ยง27-106
11/02/2004 (subsequently amended 01/06/2014)

Note: In January 2014, the Columbia City Council increased existing renewable portfolio requirements and added a new goal for the end of 2028.

In November 2004, voters in Columbia, Missouri, approved* a proposal to adopt a local renewable portfolio standard (RPS). (The state renewable electricity standard adopted by ballot initiative in November 2008 does not apply to municipal utilities such as Columbia Water & Light.) The city's municipal utility Columbia Water & Light is required to generate or purchase 30% of its electricity from eligible renewable energy resources by the end of 2028. Nearly 7% of all energy sources for 2013 were renewable according to the most recent renewable energy report.

Eligible Technologies

Eligible renewable energy sources are “wind power, solar energy, bio-energy sources or other renewable sources which meet the environmental criteria approved by the city council after review by the environment and energy commission and the water and light advisory board,” including biomass, hydropower, geothermal power.


The city is required to generate or purchase electricity generated from eligible renewable energy resources at the following levels:

  • 2% by December 31, 2007;
  • 5% by December 31, 2012;
  • 15% by December 31, 2017;
  • 25% by December 31, 2022; and
  • 30% by December 31, 2028.


By February 1 of each year, the Columbia Water & Light Department must issue a renewable energy plan, detailing a proposal for how the city intends to comply with the RPS ordinance during the following year. The plan explains the city's due diligence in pursuing renewable energy opportunities and detail all cost assumptions and related utility rate calculations, except with regard to confidential information that may be withheld pursuant to state law. It is then be reviewed by the Columbia Environment and Energy Commission and the Columbia Water & Light Advisory Board, and submitted to the Columbia City Council for approval following a public hearing.

Cost Mitigation Measures

The standard will be met to the extent possible without increasing electric rates by more than 3% as a result of the standard. (Columbia Water & Light successfully exceed its 2013 RPS requirement at a rate impact of only 1.1%.)

* The RPS was approved by 78% of voters, with no organized opposition.
