The document discusses SMUD's renewable energy goals and plans to acquire concentrating solar thermal (CST) power. SMUD aims to source 20% of its electricity from renewables by 2010 and 33% by 2020. CST could provide a significant portion of these targets, with the equivalent of 1000 MW by 2010 and an additional 735 MW by 2020. SMUD issues requests for renewable energy offers and may negotiate power purchase agreements for emerging technologies like CST. CST with storage is presented as a good fit for SMUD's needs because it can generate power when demand is highest in the daytime and evenings.

2. SMUD – Quick Facts
o Sacramento California Electric Utility
o Publicly Owned – in California’s Capital
o Serving 1.5 Million People
o $1.4 Billion /yr Revenue
o 12,000 GWh/yr Electricity Sales

3. What I’m gonna' tell ya’
o How much R.E. does SMUD need?
o How does SMUD buy Solar Power?
o Why would SMUD buy CST?

4. SMUD Renewable Energy Goals
20% by 2010
2,500 GWh (~ 1000 MW of CST Equivalent !)
33% by 2020
4300 GWh (~ an additional 735 MW CST Equivalent !)

5. How‘re ya
Doin’ ?

Do that ?

8. SMUD PPA Acquisition
• Request for RE Offers
• Accept & Evaluate “Emerging Renewables”
• Screen offers for Tech, Financial, Commercial
• Negotiate

9. Is that easy ?

10. SMUD PPA Acquisition
• Solar RFP’s and Bid evaluations
need some care.
• Utility Procurement Study showed
that bidding CST to a utility RFP is
tricky, and utility understanding of
CST bids may be misunderstood

11. Why bother with
“Emerging
Tech”?

13. Why We Need CST w/ Storage
Governor’s Executive Order S-3-05; June 2005
SMUD Board Strategic Directive
o By 2010, Reduce Ghg emissions below year 2000 levels
o By 2020, Reduce Ghg emissions below year 1990 levels
o By 2050, Reduce Ghg emissions 80% below year 1990 levels
