University of California
Current 3-Year UC/IOU Partnership
• $16.5 million in projects
• 49 projects
• Of this total, $8 million covered by incentive grants (at $1/therm and
$.24/kWh) and $8.6 million financed by UC
• Yielding:
– Avoided 32 million kWh/year
– Avoided 1.8 million therms/year
• 22 MBCx projects included yielding:
– Savings of 7.3 million kWh/year
– Savings of 940,000 therms/year
• Of $3.7 million in project costs, $2.7 million was covered by
incentive grants. UC contributions totaled $1 million (or 27.2% of
total costs)
• Average payback period: a little over half a year
University of California
Policy on Sustainable Practices
Clean Energy Standard:
“…As with renewable energy projects, the University will
develop funding sources and establish a program for
financing retrofit projects. The initial goal for energy
efficiency projects will be to reduce systemwide
growth-adjusted energy consumption by 10 percent
or more by 2014 from the year 2000 base
consumption level…”
(From March 22, 2007 revision of Policy on Sustainable Practices and implementation guidelines.)

Proposed New IOU Partnership
Opportunity for significantly increased IOU funding for UC energy projects.
• IF UC can by June 2008 (March 2008 – preliminary findings):
– Produce a Strategic Energy Plan (we’ve set aside $1.8 million from Enron
settlement)
– Address internal barriers to timely implementation
– Identify and commit central matching funding
•
THEN IOUs would be prepared to fund up to $300 million over 6-year period
starting in January 2009.
– UC matching funds of approximately $200 million ($33 million a year) at
established partnership rates (currently $.24 per kWh and $1 per therm, with cap
of 80% project value)
– Partnership consultant estimated a 10% reduction goal in 2014 would equal a
reduction of 1300 million kWh, or up to $130 million per year in perpetual energy
savings (in current dollars) for UC’s $200 million investment
– Potential inclusion of Municipal Utilities (to be negotiated)
