Breakdown of 2009 Customer Energy Efficiency Savings

Appliances

Appliances include dishwashers, clothes washers, refrigerators, commercial cooking equipment and other similar equipment. One of our residential programs addresses the challenge of old, inefficient and often secondary appliances that continue to use significant amounts of electricity. We work with a third-party vendor to pick up and recycle old refrigerators, freezers and room air conditioners for free and pay participating customers a rebate of up to $35. Last year, we recycled nearly 30,000 old appliances.

Consumer Electronics

By 2020, electronics are projected to account for nearly 20 percent of the country’s residential electricity consumption, overtaking appliances and lighting.

PG&E created a first-in-the-nation incentive program to address this emerging trend and paid more than $6 million last year in incentives to retailers and manufacturers to bring the highest-efficiency TVs, desktop computers and monitors to the market.

Lighting

Switching to energy-efficient lighting is one of the most popular ways our customers save money and energy, whether at home or at work.

We provide incentives for compact fluorescent light bulbs (CFLs), T8s, T5s, occupancy sensors, LEDs, high bay linear fluorescent fixtures and ceramic metal halides, as well as exit signs and occupancy sensors. In 2009, we provided incentives for approximately 55 million CFLs and fixtures.

Refrigeration

Refrigeration accounts for 13 percent of California’s commercial electricity consumption. Upgrading these systems—from installing strip curtains for walk-in coolers to high-efficiency refrigerated display cases—can deliver big savings for commercial customers.

Starting January 1, 2010, California building code requirements are changing for all refrigerated space construction or expansion. PG&E offers free training seminars on how to comply with the new codes and apply for rebates and tax credits.

Heating, Ventilation and Air Conditioning (HVAC)

Homes or businesses with properly functioning HVAC systems operate more efficiently, which helps lower energy costs. PG&E actively encourages our residential and small business customers to install high efficiency HVAC systems and room air conditioners.

For larger customers, PG&E offers incentives for energy-efficient HVAC package units, chillers and variable frequency drives. Working through industry partners, customers saved 5 GWh in 2009, which is enough energy to power over 700 homes per year.

Process

Many manufacturers use energy-intensive processes as part of their operations. PG&E provides customized incentives for these companies to find more energy-efficient ways to run their business.

For example, Owens-Illinois, the world’s largest manufacturer of glass containers, earned $1.3 million in incentives for energy efficiency capital projects at their manufacturing facilities in Oakland and Tracy, California. At the Tracy plant, compressed air upgrades allowed the factory to shut down a 1,250 horsepower compressor that had previously been required to operate 24 hours per day, 365 days per year. The combined projects from both facilities will save 13 GWh and 1.5 MW annually.

Low Income Programs

We provide assistance to low-income, disabled and senior citizen customers through a number of financial assistance and weatherization programs.

In 2009, PG&E”s Energy Partners program treated over 80,000 homes with free measures such as CFLs, occupancy sensors, refrigerators and room air conditioners.

Codes and Standards

PG&E was instrumental in developing the new TV energy efficiency standards adopted by the California Energy Commission last year. The new standards will generate an estimated 6,515 GWh in energy savings annually after all existing stock is replaced. The overall energy cost savings for California customers is expected to be approximately $8.1 billion. Over the past 10 years, 60 standards originally researched and recommended by PG&E have been adopted into California”s building codes and appliance standards.

Office

We incent a variety of measures designed to reduce energy usage for office equipment, including installing networked power management software, upgrading inefficient office equipment and installing server virtualization software.

PG&E was the first utility in the nation to offer an incentive for server virtualization, which allows a single physical server to run multiple “virtual servers,” each with its own operating system and software, and we lead a national coalition of utilities focused on addressing the energy efficiency needs of the high tech sector.

Other

This category includes energy-efficient measures such as vending machine controllers, occupancy sensors and measures for customized projects for large commercial and industrial customers.

Safeway is using occupancy sensors to identify the presence and volume of customer traffic and direct energy usage accordingly. Occupancy sensors are now standard in all new store construction and are being considered as possible retrofit opportunities for existing facilities. Sensors currently in place save 51,000 kWh per year.

Appliances

High efficiency natural gas clothes washers and dishwashers not only save energy, they also help customers use less water. As an added incentive, PG&E and participating greater Bay Area water agencies are partnering to offer a rebate of up to $175 on qualifying clothes washers.

Heating, Ventilation and Air Conditioning (HVAC)

We provide rebates and incentives for energy-efficient HVAC products such as central natural gas furnaces and boilers. We also work with HVAC distributors, retailers and contractors to reach large numbers of customers. Through our industry partners, more than 18,000 customers received duct test and seal services on their HVAC systems in 2009.

Water Heating

We offer rebates on energy-efficient water heaters for residential and small commercial customers, while larger customers can earn incentives for efficient boilers, steam traps, ozone laundry systems and commercial pool and spa heaters.

Process

For many commercial and industrial customers, heating is an energy-intensive process using large gas-powered equipment such as industrial boilers and process heating.

In 2009, industrial customers saved more than 28 million therms by upgrading their operations with energy-efficient equipment. Last year, PG&E helped the Butte County Office of Education find the best solutions for replacing two 1950s-era automobile-sized natural gas boilers. The old systems, which were only about 60 percent efficient, were replaced with an energy-efficient boiler system that is up to 95 percent efficient.

Low Income Programs

PG&E’s Energy Partners Program helps income-qualified customers save natural gas and money on their energy bills through free weatherization services such as attic insulation, duct sealing, water heater conservation measures, furnaces and clothes washers.

Other

This category includes energy-efficient measures such as gas water heater boiler controls, low flow shower heads and customized measures such as ozone laundry systems, a relatively new technology that eliminates the need for hot water during the laundry cycle. In 2009, customers that installed ozone laundry systems received approximately $80,000 in incentives and saved approximately 96,000 therms.

Low Income Programs

We provide assistance to low-income, disabled and senior citizen customers through a number of financial assistance and weatherization programs.

In 2009, PG&E’s Energy Partners program treated over 80,000 homes with free measures such as CFLs, occupancy sensors, refrigerators and room air conditioners.
