Responding to a December
state executive order to "reduce grid-based energy purchases
by 20% by 2015," a partnership between Californias
public universities and investor-owned utilities will spend
up to $300 million to reduce energy use on all 33 campuses in
the utility service areas.
Utilities participating in the
program include Pacific Gas and Electric Co., San Francisco;
San Diego Gas & Electric, San Diego; Southern California
Edison Co., Rosemead; and Southern California Gas, Los Angeles.
With 23 campuses, California State University is leading the
university effort.
The program consists of evaluating
and retrofitting buildings and other facilities for better
energy performance and training facilities staff to squeeze
the most performance out of existing facilities. Len Pettis,
CSUs chief of Plant Energy and Utilities, estimates
that about half of the $300 million will be spent on improving
infrastructure to achieve conservation and half will go for
building clean, ultra-clean and renewable power generation
sources for campuses.
The university system has preapproved
seven energy service companies to advise on how to meet campus
energy needs. Companies will bid on a comprehensive design-build
contracts for individual campuses. Those that do not win the
contract will be paid for their time. "We see it as a
partnership where we are fair with them and they are up-front
with us and dont pencil us to death later," says
Haaziq Muhammad, a lead contract specialist for the CSU Chancellors
office.
Each campus determines its own
needs, Pettis says. A renovated facility at Sonoma State completed
in December 2002, for example, replaces a traditional mechanical
cooling system with 1,325 photovoltaic cells to run fans and
evaporative-cooling equipment. The 106-kW facility cost approximately
$7 million, with PG&E covering about half the cost.
"The cost savings have to
be greater than the debt service starting in year one,"
says Marco Garcia, a major-accounts manager for Berkeley-based
PowerLight Corp., which performed the technical design and
economic analysis and facilitated a low-interest loan for
the Sonoma State project. But Pettis maintains that photovoltaics
are not cost effective over their 30-year lifespan without
significant incentives. And since none of the campuses are
located in good wind-generating areas, he will be looking
at fuel cell technology as an alternative.
Four CSU campusesHumboldt,
San Francisco, San Jose and San Diegohave power generation
on site and Long Beach is planning a 15-MW combined-cycle
natural-gas plant. "We would like to move away from fossil
fuel eventually, but right now, it is still the most cost-effective
way to generate power," Pettis says.
