2019 Annual Report


The Southwest region of the United States made great progress in 2019 to advance energy efficiency. Highlights of accomplishments led or supported by the Southwest Energy Efficiency Project (SWEEP) include:

  • Electric utilities in the Southwest helped their customers save about 2,300 gigawatt hours (GWh) per year from energy efficiency programs implemented in 2019, which is equivalent to the electricity use of 230,000 typical households in the region.
  • Electric utility energy efficiency programs implemented in 2019 will provide households and businesses about $1 billion in net economic benefits, while also reducing CO2 emissions by approximately 16 million metric tons over the lifetime of the measures installed during the year.
  • New Mexico adopted new energy savings standards for utility energy efficiency programs.
  • Colorado adopted energy and water efficiency standards for 15 residential and commercial products sold in the state in 2019.
  • The Salt River Project adopted new Sustainability Goals, including goals for energy efficiency programs, demand response, electric vehicle adoption, and strategic electrification through 2035.
  • State and local governments continued to adopt the latest version of the International Energy Conservation Code (IECC). Most of the new construction in the region is occurring in jurisdictions that have adopted an up-to-date building energy code.
  • The market for electric vehicles (EVs) is growing rapidly in the Southwest, with sales of plug-in vehicles in our region tripling from 2017 to 2019.
  • Colorado adopted the Zero Emissions Vehicle Program, which will require manufacturers to deploy an increasing number of EVs in the state. In addition, both Nevada and New Mexico announced plans for adoption.
  • Colorado and New Mexico passed legislation in 2019 requiring utility companies to make significant investments in transportation electrification.
