Could Solar Shine in a Tucson City-Utility Partnership?

A city in the sunny southwest, Tucson is wondering how it can maximize its use of cost-effective, economy-boosting solar power. Is a partnership with the electric utility, as seen in Minneapolis, the answer?

ILSR’s Director of Democratic Energy gave this presentation to several audiences on a recent (delightful) visit to Tucson, Arizona, to explore the dissonance between the electric utility’s 15-year plan and the city’s energy and environmental goals, and to inspire city residents and the utility to look for common ground.

  • Tucson, AZ, has the best solar resource in the U.S.
  • The incumbent utility, Tucson Electric Power, is owned by Canadian company Fortis and responsible to the elected Arizona Corporation Commission.
  • Its 15-year resource plan includes a lot of substitution for new natural gas power in place of coal, still a water intensive source of energy in a desert.
  • The plan includes a much smaller portion of new solar energy despite Tucson’s excellent solar resource.
  • The utility’s resource plan includes inflated costs for solar energy.
  • Residents of Minneapolis have compelled their private electric company into partnership with the city around its energy goals, and Tucson could do the same.
