Electricity Service Supplier

Where can I get Electricity Service Supplier (ESS) information?

Five ESSs – Constellation NewEnergy, Iberdrola Renewables, LLC, Calpine Energy Solutions, 3 Phases Renewables and EDF Energy Services, LLC – have executed the required agreements and are eligible to serve Pacific Power business customers in Oregon. 

Although they have not entered into agreements with Pacific Power, you can view a list of OPUC-certified ESSs

An Open Access Transmission Tariff (OATT) (PDF)applies to ESS service. Most customers would work with their ESS to understand these charges. Please familiarize yourself with this information and contact us with questions, by sending an e-mail

ESSs that are already registered with the State of Oregon can get more information about our ESS certification process
