San Francisco Public Utilities Commission Continues Solar Energy Leadership with Approval of New Solar Array Atop Pier 96 Norcal Recycling Center

Approval of 18,500 Sq. Ft. Solar Energy System at Pier 96 Comes as New Data Shows Moscone Center System Exceeding Solar Generation Projections in First Year

SAN FRANCISCO, SEPT 28, 2005 - The members of the San Francisco Public Utilities Commission (SFPUC) just approved an agreement to design and install an 18,500 square foot photovoltaic solar power system on the rooftop of the Norcal, Inc. Recycling and Disposal Center at Pier 96. The new 283-kilowatt solar array will generate one-third of the electricity needed to power the 200,000 square foot facility's recycling operations and will produce equivalent energy to power more than 100 homes. The SFPUC approval of the new agreement comes as year-end data shows the SFPUC's largest municipal installation at the Moscone Center solidly exceeding performance targets in its first year of operation.

"With the new Pier 96 solar system, San Francisco will take another step toward clean energy leadership," said Barbara Hale, SFPUC Assistant General Manager for Power. "With these and other solar investments, the SFPUC will meet a growing portion of our municipal electrical needs with clean, renewable energy resources."

Following approval of a lease agreement by the San Francisco Port Commission, San Francisco's Pier 96 solar system will be the SFPUC's second large-scale municipal solar installation to get underway this year. A new 18,500 square foot, 225-kilowatt solar system at the SFPUC's Southeast Water Pollution Control Plant is scheduled to go online in October. Together, the solar installations and energy efficiency initiatives at the Moscone Center, Southeast Water Pollution Control Plant and Pier 96 will generate 1.5 megawatt hours per year, roughly the energy needed to power approximately 500 homes for a year. "These photovoltaic panels will provide a new source of clean, renewable energy, and the power will be used to help sort recyclables from San Francisco," said Brad Drda, Environmental Program Manager at Recycle Central.

The SFPUC also reported today that new year-end data for its 675-kilowatt solar array at the Moscone Center, which first came online in 2004, show the system producing 5% more electricity than projected in its first complete year of operation. Factoring in the energy efficiency savings from a major lighting renovation also completed at the facility, the Moscone Center Energy Project generates nearly $600,000 in annual utility savings. Over the next 30 years the solar generated electricity and energy efficiency measures will reduce emissions of carbon dioxide by 35,000 tons. This emission reduction is equivalent to removing 7,000 cars from the road, or not driving 88 million miles.

"We applaud San Francisco's leadership in implementing comprehensive energy strategies that integrate clean solar electric power and on-site energy efficiency," noted Dan Shugar, President of the PowerLight Corporation, which designed and built the Moscone Solar deployment. "San Francisco is demonstrating how local governments can improve air quality while saving taxpayers' dollars."
