 as revised, with an effective date of April 16, 2025, on condition that the issues raised in the filing would continue to be evaluated in a new Commission docket, UM 2377. This initial approval allowed PGE to begin working with large load customers to form a load interconnection queue, conduct studies to assess and allocate connection costs, and offer study and service agreements. Applicable agreements with new large load customers may be revised and updated based on the outcome in the separate OPUC proceeding, UM 2377, that was opened to address PGE’s proposed tariff changes and related issues.

In June 2025, the Oregon Legislature passed HB 3546 relating to service to large data centers. HB 3546, which became effective in June 2025, directs the OPUC to provide a classification for retail customers deemed large energy use data center facilities. Any tariffs for the class must allocate costs to the class in a manner that is equal or proportional to the costs of serving the class, or directly assign the costs to large energy use data center facilities and avoid unwarranted shifting costs to other classes. HB 3546 also directs the OPUC to require that electric companies serving data centers must enter into a contract for services with such customer under terms and conditions specified by the law. The OPUC has included HB 3546 alignment and establishment of a data center classification for retail customers within the scope of UM 2377 as well as other topics that may apply to all large load customers.

Operating Activities

In addition to providing electricity from PGE’s own generation portfolio, to meet retail load requirements and balance energy supply with customer demand, manage risk, and administer its long-term wholesale contracts, the Company purchases and sells electricity in the wholesale market. To fuel its generation portfolio, the Company purchases natural gas in the United States and Canada and sells excess gas back into the wholesale market. PGE also performs portfolio management and wholesale market sales services for third parties in the region and purchases and sells environmental credits bundled with electricity in the wholesale marketplace. 

The Company participates in the California Independent System Operator's (CAISO) western Energy Imbalance Market (EIM), which enables, among other benefits, greater integration of renewable energy onto the grid by better balancing the variable output of renewable resources. 

PGE signed an implementation agreement and filed tariff changes with the FERC to join the CAISO’s Extended Day-Ahead Market (EDAM), which is expected to build on the success of the western EIM and help provide
