PG&E Corporate Responsibility and Sustainability Report 2020

Plan of Reorganization Commitments

Buildings and Facilities

Through sustainable design, increasing the efficiency of our energy and water usage, and eliminating waste, we are continually working to reduce the environmental footprint of our buildings and facilities. Our efforts also rely on the participation of our employees, who help us reach our goals.

Our Approach

Energy, Water and Waste

We continue to execute a multifaceted strategy to invest in key facility improvements, engage employees and incorporate sustainability principles and continuous improvement into our real estate management.

In 2019, we worked to use energy and water more efficiently and divert landfill waste from our office facilities and service yards. We also remained focused on building a more sustainable supply chain through environmentally preferable product choices and procurement strategies. We also powered our service centers—about 95 facilities in Northern and Central California—with 100 percent solar energy through Pacific Gas and Electric Company’s Solar Choice program.

Hazardous and Other Waste

As part of our course of business, certain activities generate hazardous wastes. Waste is also generated during the remediation and cleanup of legacy sites.

PG&E handles all hazardous waste in accordance with federal and state regulations. Our approach includes providing training and guidance to employees to ensure waste is properly managed from the point of generation to recycling or disposal.

Applicable federal and state hazardous waste management statutes include the Resource Conservation and Recovery Act and the Toxic Substances Control Act under federal requirements and Title 22 of the California Code of Regulations and the California Health and Safety Code. California laws and regulations are more stringent and encompass broader waste streams than federal requirements.

2019 Milestones

In 2019, we continued to operate and maintain our facilities using sustainable practices. Compared to 2018, aggregated energy use intensity decreased by 8 percent and water usage increased slightly by 2 percent. The results reflect continued efforts to execute in several strategic areas to improve facility sustainability performance:

  • Earned Leadership in Energy and Environmental Design (LEED) Gold certification for our Auburn Regional Service Center, a 15-acre site with more than 200,000 square feet in six buildings. The two renovations and four new buildings are equipped with energy efficient HVAC systems, LED lighting, electric vehicle charging stations, native plant landscaping with drip system, PV solar and fixtures.
  • Received LEED Silver certification for our Livermore Electric Safety Academy’s main building, an approximately 20,000 square foot facility with many similar energy efficient features as Auburn, including drought tolerant landscaping with weather sensor irrigation equipment. We also submitted a LEED application, targeting Gold certification, for the new Substation Training Center building at the same Livermore facility, and anticipate confirmation in 2020.
  • Expanded our use of on-site renewable energy by completing the installation of solar photovoltaic systems at five different facilities: 412-kW at Merced Service Center, 350-kW at Auburn Regional Center, 145-kW at Lemoore Service Center, 167-kW at Fresno Service Center and 356-kW at Livermore Electric Safety Academy. These new installations represent an increased electricity production of approximately 2.2 million kWh per year. Plans to complete new solar projects are in progress at two other facilities in 2020, which will add more than 1,000 kW to our solar portfolio.

  • 2. Data will become available during the 2020 reporting period.2

Other waste reduction efforts in 2019 included:

  • Recycling 32.6 million pounds of scrap iron, aluminum and copper from conductors, steel, meters, transformer oil and miscellaneous material. We recycled 19.7 million pounds of transformers; nearly 900,000 pounds of recovered meters; 154,000 pounds of HDPE plastic, including pipes and hard hats; 578,000 pounds of street-light fixtures; 2.1 million pounds of transformer oil; and 4.4 million pounds of miscellaneous materials such as glass and cardboard.
