Power Delivery Information
Through PaloAltoGreen, CPAU will continue to provide electricity to your premises. When you join PaloAltoGreen, CPAU purchases solar renewable energy certificates equal to the amount of electricity you use. Renewable energy is delivered to various points on the electrical system. Once delivered to the system, renewable power mixes with power from other electrical generation plants. Because of this, CPAU cannot guarantee that the actual electricity generated from renewable sources is delivered to a specific home or business.

Large Business Rates
Large businesses (E4 and E7 rat classes) participate in PaloAltoGreen by purchasing 1,000 kWh blocks of renewable energy.  The cost is $15 per 1,000 kWh block.  A business may buy renewable energy to equal 100% of its electricity use, or some portion, in 1,000 kWh increments.  To learn more, visit the PaloAltoGreen business page.

Green-e Energy Certified Renewable Energy
To ensure the environmental integrity of your purchase, all PaloAltoGreen renewable energy is verified through Green-e Energy, an independent third-party that acts on behalf of consumers. The Green-e logo helps consumers easily identify environmentally superior renewable energy options. For more information on Green-e Energy certification requirements, call 1-888-63-GREEN or log on to
