RPS Mandates
• Applies to members in Colorado and New Mexico
• 5% renewable energy by 2015
• 10% renewable energy by 2020
• Socialization of cost• Socialization of cost
• Existing Renewables584 MW f WAPA (d ’ )- 584 MW of WAPA (doesn’t count)
- 11 MW Small PPAs (hydro/bio)
Tri-State Policy 115 – Member Generation• Allows members to provide own generation resources Allows members to provide own generation resources
up to 5% of their total annual load requirements– Distributed generation (DG) or renewable generation
• Tri-State’s Goals:– Facilitate members’ desire for local projects
No rate pressure on Tri-State’s Class A rate up or down– No rate pressure on Tri-State s Class A rate – up or down– Compatible with any rate design– RECs generally used for RPS compliance
• Results to Date:– 10 projects totaling about 11 MW
Small hydro heat recovery and solar– Small hydro, heat recovery and solar

2010 S l El t i P A i ti ’ 2010 Solar Electric Power Association’s Utility Solar Rankings
Top 10 U.S. utilities that added most new solar power to their systems last year• Tri-State ranked #6 nationally (30 MW)• Tri-State highest ranked cooperative utility
Ci l t l t i ti l PV j t• Cimarron largest electric cooperative solar PV project• Kit Carson Electric Cooperative (Taos) ranked #2
nationally with 22.2 watts per customer and #4 with nationally with 22.2 watts per customer and #4 with production of 620 kilowatts
Conclusions
• PV is a credible but not inexpensive resource• PV is a credible, but not inexpensive resource• Tri-State service territory is well suited
– latitude clouds inexpensive land– latitude, clouds, inexpensive land
• Geographically distributed arrays should help fast ramping issuesp g
• PV prices should continue to drop• Fixed array = no moving parts/low maintenance• Few permanent employees
