PG&E Recognizes 365 Main for Data Center Energy Reduction Programs San Francisco Data Center Energy Reductions Contribute to Power Reliability and Environmental Protection

 SAN FRANCISCO, Calif., March 14, 2007 Pacific Gas and Electric Company has recognized 365 Mains San Francisco data center for its noteworthy energy-reduction accomplishments while participating in PG&Es Critical Peak Pricing (CPP) program. The CPP program is designed to curtail energy load during critical peak days to offset the possibility of an energy emergency.

The issue of reducing power consumption within data centers is gaining national attention. Data centers can use up to one hundred times the energy per square foot of typical office space and account for an estimated 1 percent to 2 percent of the nation's electricity consumption.

We are pleased to highlight the level of commitment 365 Main has made to manage its energy consumption responsibly, and this type of action is exactly why we created the CPP program, said Al Steubing, PG&E Account Services Director. 365 Main is truly walking the walk in the data center segment, and we encourage other companies to follow its lead in order to protect all types of businesses from potential power outages on critical peak days and to preserve the environment.

In February, PG&E announced that it is leading the formation of a nationwide coalition of utilities to discuss and coordinate energy efficiency programs for the high tech sector, focusing specifically on data centers. The coalition will look for ways to implement many of PG&Es successful data center energy efficiency programs.

PG&E reported that 365 Mains San Francisco data center saved $70,000 in utility costs through their participation in the CPP in 2006. 365 Main has since opened an additional Bay Area data center in Oakland that will also participate in CPP in 2007.

365 Main recognizes the importance of improving data center efficiency, and we are taking proactive steps to dramatically reduce our power usage, said Chris Dolan, CEO. We care about the communities in which we do business, and participating in PG&Es CPP program helps ensure power uptime for everyone, especially during those critical summer months. Were very proud of the results weve achieved so far and will continue looking for ways to improve.

365 Mains energy-saving approach

Working directly with PG&E, 365 Main began its energy-saving program by conducting energy audits to reduce power consumption during peak months. The company immediately updated lighting controls and installed efficient motor controllers in its intricate air conditioning system to reduce power consumption. The most significant power reduction, however, was attributed to an innovative testing procedure for the buildings back-up generators.

Each of 365 Mains five national data centers is equipped with powerful back-up generators to ensure customer uptime in the event of a power outage. In 365 Mains founding data center in San Francisco, the company maintains ten 2.1 MW (megawatt) generators manufactured by Hitec. These generators, known as Continuous Power System (CPS) generators, run 24 hours a day, ready to deliver 100 percent power to the data center in the event of an outage.

As part of a comprehensive preventative maintenance program, 365 Main tests each Hitec generator once a month by running each of the 3000 horsepower diesel engines for two hours. By replacing a dated, inefficient generator-testing procedure, 365 Main reduced utility power consumption by as much as 12.5 percent during monthly tests. The innovative testing procedure eliminated 100 percent reliance on load-banks eight foot tall heating coils traditionally used to test generators by drawing immense amounts of power and is compliant with the guidelines set by the Bay Area Air Quality Management District (BAAQMD).

365 Main has made the testing methodology available to PG&E to share with other data center providers to address rising concerns over data center power consumption.

How PG&Es Critical Peak Pricing program works

Hundreds of PG&E business customers participate each year in the PG&Es voluntary CPP program, which offers seasonal discounts to single-building customers that reduce or shift their energy usage away from peak periods between May 1 and October 31.

CPP events are generally triggered by temperature but may also be activated by PG&E as warranted by extreme system conditions. PG&E customers that belong to the CPP program are given financial incentives to reduce or shift their energy usage away from peak periods during CPP events. During a CPP event, electric rates for these customers are higher than average during peak hours between noon and 6 p.m., but electric rates are discounted during the peak and partial-peak periods during the summer, which starts May 1 and ends October 31. PG&E notifies CPP participants by 12:00 noon the day before a CPP event is to be called.

CPP events include:

• Special alerts issued by the California Independent System Operator
• Conditions of high forecasted California spot market power prices
• Testing /evaluation periods
