Power Content Label

Low rates are just one of the reasons to be happy with your service from Silicon Valley Power. That's because Silicon Valley Power provides electricity that is not only highly reliable, but environmentally friendly as well. By offering power from a variety of sources, we are able to reduce the impact on the environment and provide clean energy to all of our customers. In January 2018, Silicon Valley Power began providing 100% carbon-free power to all residential customers. This is reflected in the Power Content Label through separate products for the residential and non-residential mix. The chart below shows a breakdown of different types of power supplied to Silicon Valley Power's customers.

Notes
  • This label does not reflect compliance with the Renewables Portfolio Standard (RPS), which measures the use of tracking instruments called Renewable Energy Credits (RECs) over the course of multi-year compliance periods. RECs that are purchased separately from the renewable energy ("Unbundled RECs") can be used for RPS compliance, but they do not factor into the power mixes or GHG emissions intensities above.

  • GHG intensity figures exclude biogenic CO2 and emissions from geothermal sources and grandfathered imports of firmed-and-shaped energy. For detailed information about all GHG emissions from California's retail electricity suppliers, visit the CEC webpage at the link below.

  • Unspecified power is electricity purchased from a genericized pool on the open market.

For specific information about this electricity portfolio, contact: City of Santa Clara dba Silicon Valley Power at (408) 244-SAVE (7283).

What is the Power Content Label? 

California State legislation (SB 1305) requires all energy service providers, such as Silicon Valley Power, to annually inform their customers of the source of power that are being sold. Such information is provided in the form of a Power Content Label. Think of the Power Content Label as a “nutrition label” for electricity. This label provides reliable information about the energy resources used to generate electricity, enabling you to easily compare the power “content” of one electricity product with that of another.
