Power Sources – PCL

Where Your Energy Comes From

Power Content Label

As a Peninsula Clean Energy (PCE) customer we committed to you on day one to only use clean energy sources and to keep your electricity as affordable as possible.

We are keeping our promises to you and below you’ll find confirmation of just how we are keeping our clean electricity promise. Think of it as an ingredient label, just like the one on your favorite foods, but for the electricity you use.

What is the Power Content Label?

The Power Source Disclosure Program is intended to help Californians understand where their electricity comes from. Every year, energy providers like Peninsula Clean Energy share details about the mix of energy sources and greenhouse gas emissions for each of their electricity plans. This information is presented on the Power Content Label, alongside a statewide reference mix called “Total California System Electricity.”

We know the table itself can be challenging to read, so we’re working to make it more accessible.

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.
