Editor's Notes
- Ladies and Gentlemen: Thanks for standing by and welcome to today’s session in the 42U web Seminar Series. Today’s presentation is entitled: “Energy Efficiency Leadership for Data Centers and IT ” During the presentation, all participants will be in a listen only mode. However, we encourage your questions or comments at anytime through the “chat” feature located at the lower left of your screen. These questions will be addressed as time allows. As a reminder, this Web Seminar is being recorded, today, July 25th 2008 and a recording will be sent to all attendees within 48 hours.
- Note that the beginning of the divergence between California and national numbers is in mid-1970s, which was when California and PG&E instituted energy efficiency programs.
- The California Energy Action plan and CPUC leadership are driving PG&E’s ambitious 3-year energy efficiency goals. Note that these are goals for each year, not cumulative – so the total for 3 years is over 600 MW! The total three-year program budget is just under $1 billion, with more than half of the funding dedicated to customer incentive funds.
- We continue to address energy efficiency and demand response opportunities in office buildings and clean rooms. Most clean rooms and fabrication facilities are devoted to R&D; manufacturing has moved offshore. All kinds of customers have data centers, and certainly all customers are using some level of computing technology such as PCs – and PG&E has programs for PCs and PC networks.
- An authoritative study by Jonathon Koomey at Stanford University estimates that data center energy use represents 1.2% of electric energy use nationwide. PG&E’s definition of an “Enterprise” data center is one that is operated by web-based, financial services, high tech, and co-location companies. These centers can be stand-alone, or part of a campus environment. Loads are in the tens of mW, with some individual centers approaching 100 mW. For some of these customers, energy use is second only to employee costs. The growth rate for enterprise data centers is often 20, 30, 40, or 50 percent annually! Concentrations are found in California, the Pacific Northwest, Texas and Arizona, Chicago, and the NY Metro area. Corporate data centers tend to be smaller (5 to 20 thousand square feet) and are usually part of an office complex. Growth rates are usually some low multiple of GDP – say up to 10% annually. “ Closet” servers (a PG&E-coined term!) are those serving small businesses – everything from doctors offices to wine distributors. The equipment is often located at the end of the hall in the closet marked “telecom”. This equipment is often not served by dedicated cooling systems, though these customers often end up installing dedicated package HVAC units to keep their systems cool. Remember that globally, less than a fifth of the population is currently accessing IT services. Our analogy to the space/cooling/power issue is that data center operators are finding it impossible to fit one more pizza box into their data center “oven”. New data centers have construction costs exceeding $1000 per square foot, and generally take several years to site and construct.
- Data storage growth rates are driven by a multiplicity of factors, including new financial rules such as Sarbannes-Oxley. Our customers report up to 100% annual growth rates, and we are examining energy efficiency opportunities in this area.
- This is not the only example of an “instant” data center. Sun’s “Project Blackbox” features eight equipment racks with the capability of supporting 200 kW of direct server load. Connections are provided for data, power, and chilled water. The marketing pitch is that these units can “simply be plugged in”! Imagine a forty foot container, with a connected load of 500 kW, with an additional cooling load of…

- Before PG&E adopted a targeted market approach, our programs often touched only a portion of the potential for a given customer type. For data centers, we were really good at working with customers on cooling equipment. There is lots of energy efficiency potential in cooling systems for data centers, especially related to air-side and water-side economizers, which together can provide as many as 6000 hours of “free” cooling in coastal areas of northern California.
- This usage split is from the best data center surveyed in a report by Lawrence Berkeley National Laboratory in a study underwritten by PG&E. In many data centers less than half of the energy supplied to the center is used by the IT equipment (the blue and yellow segments would be reversed). Key technical point: removing heat load in the data center results in AC system savings. In England we would call this a “knock-on” effect; in the US a “two-fer”.
- Yes, financial incentives take the form of a check written to the customer. Key program design is that customers must apply before undertaking projects; these are “incentives”, not “rebates”.
- We are anxiously awaiting the results of an industry-led effort to develop the equivalent of miles-per-gallon ratings for servers and other IT equipment, which in turn PG&E will use to provide incentives for premium efficiency equipment for both replacement and new purchase installations. We are working with the data storage equipment industry to evaluate opportunities, and have already debuted incentives for Multiple Array of Idle Disk systems. There are six to ten best practices for managing airflow in data centers, and we are developing a package of metering and monitoring systems that customers can install to measure energy savings from implementing the measures. Power supplies are certainly a focus in the industry, and we will be extending the 80+ program to data center computing equipment. This program pays incentives directly to manufacturers for using high-efficiency supplies in their equipment. We are providing $15 rebates per seat license for PC network management software that ensures PCs go into power savings mode when not in use. Several suppliers and customers are working with us to evaluate the energy efficiency benefits of moving to a thin client computing system in place of PC networks.
- Intel, AMD, HP, VMWare, Sun et al are coming up to speed on utility programs, and are prepared to launch governmental relations initiatives to expand utility programs! The coalition includes utilities from the Pacific Northwest, California, Texas, New York, Massachusetts, and Canada. The intent is to drive early adoption of programs, and then extend them to the 90+ utilities in the country that have energy efficiency program offerings. The coalition is rapidly building as other utilities express interest.
- Not all utilities who are members of the coalition or who have expressed interest in joining are represented here.
- PG&E recognizes that we have to build partnerships across this industry, with equipment manufacturers, customers, the utility industry, the regulatory community, and new players to drive success. What role will you play?
