Solar Potential in Mexico
  • Solar radiation in Mexico is one of the highest in the world, allowing for an average solar power generation of 5 KW /m2 per day.
  • A hybrid combined cycle power station, with a 25 MW thermo-solar system, is scheduled to begin operations in 2009, in Agua Prieta, Sonora.

opportunities for renewables at the arizona sonora border
Opportunities for Renewables at the Arizona/Sonora Border
  • Growth = renewable energy opportunities
  • Border area has highest North America solar resource
  • Open space favors solar deployment
  • Solar energy has the double advantage of being abundant and using least water
