Portland General Electric Company (PGE) operates as a vertically-integrated electric utility. The company engages in the generation, wholesale purchase and sale, transmission, distribution, and retail sale of electricity to customers in the state of Oregon (State).
PGE meets its retail load requirement with both company-owned generation and power purchased in the wholesale market. The company participates in the wholesale market through the purchase and sale of electricity, natural gas, and environmental credits in an effort to obtain reasonably-priced power to serve its retail customers, manage risk, and administer its long-term wholesale contracts. PGE is committed to developing products and service offerings for the benefit of retail and wholesale customers.
PGE’s State-approved service area allocation of four thousand square miles is located entirely within Oregon and includes 51 incorporated cities. During 2024, the company added sixteen thousand customers, and as of December 31, 2024, served a total of 950 thousand retail customers.
Power Supply
PGE utilizes its generating resources, as well as wholesale power purchases from third parties, to meet the needs of its retail customers. The volume of electricity the company generates is dependent upon, among other factors, the capacity and availability of its generating resources and the availability of wholesale power and natural gas. As part of its power supply operations, the company enters into short- and long-term power and fuel purchase and sale agreements. PGE executes economic dispatch decisions concerning its own generation and participates in the wholesale market in an effort to obtain reasonably-priced power for its retail customers, manage risk, and administer its long-term wholesale contracts. The company also performs portfolio management and wholesale market sales services for third parties in the region and purchases and sells environmental credits in the wholesale marketplace. In addition, the company encourages energy efficiency measures to help meet its energy requirements and promotes the use of various demand side management products to reduce load during peak time usage.
Customers and Revenues
PGE generates revenue primarily through the sale and delivery of electricity to retail customers located exclusively in Oregon. In addition, the company distributes power to Direct Access customers that choose to purchase their energy from an ESS. Although the company includes such customers in its customer counts, and energy delivered to such commercial and industrial customers in its total retail energy deliveries, retail revenues include only delivery charges and applicable transition adjustments for these Direct Access customers, as the customers purchase energy directly from the ESSs. The company conducts retail electric operations within its State-approved service territory.
Retail Revenues
Retail customers are classified as residential, commercial, or industrial, with no single customer representing more than 9% of PGE’s total retail revenues or 14% of total retail deliveries during 2024.
Residential customers include single family housing, multiple family housing (such as apartments, duplexes, and town homes), mobile homes, and small farms. Residential demand is sensitive to the effects of the weather and seasonal temperature changes lead to variations in both heating and cooling needs. Based on the climate in PGE’s service area, the heating season tends to span a longer time period while cooling needs, although robust, are reflected over a shorter span concentrated in the summer months of June through September.
Commercial customers consist of non-residential customers who accept energy deliveries at voltages equivalent to those delivered to residential customers. This customer class includes most businesses, small industrial companies, and public street and highway lighting accounts. The company’s commercial customer demand is somewhat less susceptible to weather conditions than residential customer demand. Economic conditions and fluctuations in total employment in the region can be indicative of changes in energy demand from commercial customers. Energy efficiency measures also impact commercial demand, as measures have focused on the commercial sector in recent years.
Industrial customers consist of non-residential customers who accept delivery at higher voltages than commercial customers. Demand from industrial customers is primarily driven by economic conditions, with weather having limited impact on this customer class. Strength in the high-tech manufacturing and digital service sector, along with new data center facilities coming online, continue to place upward pressure on deliveries to industrial customers. Favorable tax policies, both State and Federal, and connectivity both locally and to overseas markets via the transpacific cable have led to strong data center development in PGE's service area.
Customer Choice Programs—In addition to standard cost-of-service pricing, the company offers different pricing options. The company also offers various energy shifting programs like Peak Time Rebates, Smart Thermostat, Time of Day, and Smart Charging, all of which enable PGE to safely reduce power use on the system during peak demand. The company provides the electricity, and Direct Access, whereby customers purchase electricity directly from an ESS.
PGE receives revenue from Direct Access customers only for the transmission and delivery of the volume of electricity delivered, along with fixed transition adjustments intended to mitigate the shifting of excess charges to the company’s cost-of-service customers. Certain large commercial and industrial customers may elect a fixed three-year or a minimum five-year term, to be served either by an ESS, or by the company under the daily market index-based price option. Participation in the fixed three-year and minimum five-year opt-out programs for existing and planned load is capped at 300 average megawatts in aggregate.
PGE is also required to offer to eligible customers, enrollment in the New Large Load Direct Access program, which is capped at 119 average megawatts in total, for unplanned, large, new loads and large load growth at existing sites.
PGE’s customers have a desire for purchasing clean energy, as over 230 thousand residential and small commercial customers voluntarily participate in PGE’s Green Future Program, the largest renewable power program by participation in the nation. Oregon’s most populous city, Portland, and most populous county, Multnomah, have each passed resolutions to achieve 100 percent clean and renewable electricity by 2035 and 100 percent economy-wide clean and renewable energy by 2050. Other jurisdictions in PGE’s service area have set, or are considering, similar goals.
The company’s Green Future Impact Program, which allows for customer-provided renewable resources, PGE-provided power purchase agreements (PPAs) for renewable resources, and company-owned, cost-of-service resources under certain options, enables commercial and industrial customers access to bundled renewable attributes from those resources. The total available capacity under the program is 750 MW.
Wholesale Revenues
PGE participates in the wholesale electricity marketplace in order to balance its supply of power to meet the needs of, and obtain reasonably-priced power for, its retail customers, manage risk, and administer its long-term wholesale contracts. Interconnected transmission systems in the western United States and Canada serve utilities with diverse load requirements and allow the company to purchase and sell electricity, largely through bi-lateral agreements, within the region to serve retail demand.
The company also participates in the California Independent System Operator’s (CAISO) western Energy Imbalance Market (western EIM), which allows for load balancing with other western EIM participants in five-minute intervals. Wholesale revenues represented 16% of total revenues in 2024.
Other Operating Revenues
Other operating revenues consist primarily of gains and losses on the sale of natural gas volumes purchased that exceeded what was needed to fuel the company’s generating facilities, as well as revenues from transmission services, excess transmission capacity resales, pole attachment rentals, and other electric services provided to customers.
Seasonality
Demand for electricity by PGE’s residential and, to a lesser extent, commercial and industrial customers is affected by seasonal weather conditions. The company uses various measures, including heating and cooling degree-days and wind speeds to determine the effect of weather on the demand for electricity.
Generation
PGE’s generating resources consist of six thermal plants (natural gas- and coal-fired), four wind farms, and seven hydroelectric facilities.
Thermal: The company has five natural gas-fired generating facilities: PW1, PW2, Beaver, Coyote Springs Unit 1 (Coyote Springs), and Carty Generating Station (Carty).
The company also has a 20% ownership interest in the Colstrip Units 3 and 4 coal-fired generating plant (Colstrip), which is located in Colstrip, Montana and operated by a third party.
Wind: PGE owns and operates two wind farms, Biglow Canyon Wind Farm (Biglow Canyon) and Tucannon River Wind Farm (Tucannon River). Biglow Canyon, located in Sherman County, Oregon, consists of 217 turbines with a total nameplate capacity of 450 MW. Tucannon River, located in southeastern Washington, consists of 116 turbines with a total nameplate capacity of 267 MW.
During 2020, the wind component of Wheatridge, located in Morrow County, Oregon, was placed into service. PGE owns 40 turbines with a total nameplate capacity of 100 MW and purchases the output of the remaining turbines, with a nameplate capacity of 200 MW through a PPA.
On January 5, 2024, substantial completion was achieved on the Clearwater wind energy facility, located in Eastern Montana. PGE owns 75 turbines with a total nameplate capacity of 208 MW.
Hydro: The company’s FERC-licensed hydroelectric projects consist of Pelton/Round Butte on the Deschutes River near Madras, Oregon, four plants on the Clackamas River, and one on the Willamette River.
PGE has a 50.01% ownership interest in the 455 MW Pelton/Round Butte hydroelectric project, with the remaining interest held by the Confederated Tribes of the Warm Springs Reservation of Oregon (CTWS). A 50-year joint license for the project, which is operated by PGE, was issued by the FERC in 2005. The CTWS has an option in 2036 to purchase an undivided 0.02% interest in Pelton/Round Butte.
Fuel Supply—PGE contracts for natural gas and coal supplies required to fuel the company’s thermal generating plants, with certain plants also able to operate on fuel oil, if needed. In addition, the company utilizes financial instruments such as forward, future, swap, and option contracts to manage its exposure to volatility in natural gas prices.
Natural Gas: Physical supplies of natural gas are generally purchased up to twelve months in advance of delivery and based on anticipated operation of the plants.
PGE owns 79.5%, and is the operator of record, of the KB Pipeline, which directly connects PW1, PW2, and Beaver to the Northwest Pipeline, an interstate natural gas pipeline operating between British Columbia and New Mexico by Williams Northwest Pipeline. PGE transports natural gas on the KB Pipeline for its own use under a firm transportation service agreement, with capacity offered to others on an interruptible basis to the extent not utilized by the company.
PGE has access to 159,726 Decatherms (Dth) per day of firm natural gas transportation capacity on the Northwest Pipeline to serve the three plants.
PGE has access to 4.1 billion cubic feet of natural gas storage in Mist, Oregon from which it can draw when economic factors favor its use or in the event that natural gas supplies are interrupted. The storage facility, owned and operated by NW Natural, may be utilized to provide fuel to PW1, PW2, and Beaver.
To serve Coyote Springs and Carty, PGE has access to 119,500 Dth per day of firm natural gas transportation capacity on three pipeline systems accessing the gas market in Alberta, Canada.
Coal: The Colstrip co-owners obtain coal to fuel the plant via conveyor belt from a mine that lies adjacent to the facility and is the sole source of coal supply for the plant. The coal supply contract with the owner of the mine is scheduled to expire at the end of 2025. The terms of the contract and the quality of coal are expected to allow the facility to operate within required emissions limits.
Purchased Power
PGE supplements its own generation with power purchased in the wholesale market to meet its retail load requirements, manage risk, and administer its long-term wholesale contracts. The company utilizes short- and long-term wholesale power purchase contracts in an effort to provide the most favorable economic mix.
The strategy allows the company to take positions in power and fuel markets up to five years in advance of physical delivery. The company’s major power purchase contracts consist of the following (also see the preceding table which summarizes the average resource capabilities related to these contracts):
Hydro—During 2024, the company had the following agreements:
Public Utility Districts—PGE has long-term power purchase contracts with certain public utility districts (PUDs) in the state of Washington for a portion of the output of certain hydroelectric projects on the mid-Columbia River. Although the projects provide PGE a total of 1,010 MW of nameplate capacity through contracts as shown below, actual energy received is dependent upon river flows and capacity amounts may decline over time:
258 MW of average variable capacity with Douglas County PUD that expires in 2025;
434 MW of capacity under a contract expiring in 2026 in which PGE will purchase a 20% share of the project output and sell varying amounts of energy in accordance with contract terms back to the PUD in order to meet their load requirements;
65 MW of average monthly capacity with Douglas County PUD that expires in 2028;
79 MW of capacity under a contract expiring in 2030, with an option to renew until 2032, in which PGE will purchase 10% of the project output. PGE will sell 25 MW back to the PUD from 2024 to 2025; and
174 MW of capacity with Grant County PUD that expires in 2052.
CTWS—PGE has a long-term agreement under which the company purchases output from the CTWS’ interest in the Pelton/Round Butte hydroelectric project. Although the agreement provides approximately 224 MW of net capacity, actual energy received is dependent upon river flows. The term of the agreement coincides with the term of the FERC license for this project, which expires in 2055. Under a separate PPA executed in 2014, PGE paid fixed capacity and energy charges to the CTWS for 100% of its share of the project through 2024. The CTWS exercised their option to purchase an additional undivided 16.66% ownership interest in Pelton/Round Butte effective January 1, 2022. As a result of the sale, capacity from company-owned generation decreased by approximately 76 MW, and capacity from purchased power increased by a corresponding amount. Under the PPA, PGE purchases 100% of the CTWS’s additional share of the project and payments under the PPA increase proportionately. PGE and the CTWS executed an additional 16-year PPA which begins on January 1, 2025, that effectively extends the term from 2024 to 2040 and increases the capacity payments in the extension period.
Other—The remaining capacity is primarily comprised of a contract with Portland Hydro, which expires in 2032, that provides for the purchase of power generated from hydroelectric projects with capacity of 36 MW.
PURPA qualifying facilities—PGE is required to purchase power from PURPA qualifying facilities (QFs), as mandated by federal law. QFs are generating facilities that fall within one of the following two categories: i) qualifying generation facilities with a capacity of 80 MW or less and whose primary energy source is renewable (hydro, wind, solar, biomass, waste, or geothermal); or ii) qualifying cogeneration facilities that sequentially produce electricity and another form of useful thermal energy (e.g., heat, steam) in a way that is more efficient than the separate production of each form of energy. As of December 31, 2024, PGE had contracts with 69 online QFs, providing a total of 315 MW of capacity. As of December 31, 2024, PGE had two contracts with QFs representing 116 MW of capacity that are not yet operational, of which two of the QF PPAs are in default because the QFs have failed to complete construction and become operational by the date required by the PPA. The PPAs provide that the QF must cure its default within a period specified under the contract terms.
Dispatchable Standby Generation(DSG)—PGE has a DSG program under which the company can dispatch and monitor customer-owned backup generators to provide NERC-required operating reserves. As of December 31, 2024, there were 78 generators with a total DSG nameplate capacity of 129 MW. PGE continues to pursue expansion of the program through ongoing engagement with customers and incorporation of battery energy storage.
Wind—PGE has four contracts to purchase power generated from renewable wind resources. Although the projects as shown below provide PGE a total of 400 MW of capacity, the expected energy from these wind resources will vary from the nameplate capacity due to varying wind conditions:
25 MW of capacity that expires in 2028;
75 MW of capacity that expires in 2035;
200 MW of capacity that expires in 2051; and
100 MW of capacity that expires in 2053.
Solar—PGE has five contracts representing 219 MW of capacity to purchase power generated from photovoltaic solar projects. Two of these projects extend to 2036 while the other three extend to 2037, 2038, and 2042, respectively. The expected energy from these solar resources will vary from the nameplate capacity due to varying solar conditions.
Green Future Impact Program— PGE has three contracts representing 360 MW of capacity to purchase power generated from renewable resources to support the Green Future Impact Program:
a 15-year contract with Avangrid Renewables representing 162 MW from a renewable solar facility in Gilliam County, Oregon that was placed in service in January 2023. This capacity is reflected within solar purchased power in the resource and contracted capacity table above;
a 25-year contract with Avangrid Renewables representing 138 MW from a renewable solar facility in Wasco County, Oregon that is expected to be placed in service in January 2026. This additional capacity is not reflected in the resource and contracted capacity table above; and
a 25-year contract with Avangrid Renewables representing 60 MW from a renewable solar facility in Wasco County, Oregon that is expected to be placed in service in January 2026. This additional capacity is not reflected in the resource and contracted capacity table above.
Biomass—PGE had one contract to purchase biomass energy that expired in January 2025.
Natural gas heat rate call option—In order to provide additional dispatchable firm capacity to meet customer demand, PGE has entered into a physical heat rate call option for 250 MW of the capacity, energy, and attributes associated with the facility. The contract begins in July 2025.
Short-term contracts—These contracts are for delivery periods of one month to one year in length. They are entered into with various counterparties to provide additional firm energy to help meet the company’s load requirements.
PGE also utilizes spot purchases of power in the open market to secure the energy required to serve its retail customers. Such purchases are made under contracts that range in duration from 15 minutes to less than one month. PGE is a market participant in the western EIM, which allows certain of the company’s generating plants to receive automated dispatch signals from the CAISO for load balancing with other western EIM participants in five-minute intervals.
Energy Storage
Resources in PGE’s energy storage portfolio that are in operation and under development as of December 31, 2024, are primarily as follows:
Wheatridge—The Wheatridge Renewable Energy Facility includes a 30 MW battery component. Subsidiaries of NextEra Energy Resources, LLC own the solar and battery components, and sell their portion of the output to PGE.
Sundial —PGE entered into a storage capacity agreement for a 200 MW Battery Energy Storage System (BESS) in Troutdale, Oregon. NextEra Energy Resources, LLC owns the resource and sells the capacity to PGE under a 20-year agreement. The project was placed in-service in December 2024.
Coffee Creek—PGE entered into an agreement to construct a 17 MW BESS in Sherwood, Oregon. PGE owns the resource. The project was placed in-service in November 2024.
Constable —PGE entered into an agreement to construct a 75 MW BESS in Hillsboro, Oregon. PGE owns the resource. The project was placed in-service in December 2024.
Seaside Grid—PGE entered into an agreement to construct a 200 MW BESS in Portland, Oregon. PGE will own the resource. The project has an estimated commercial operation date of June 30, 2025.
Transmission and Distribution
Transmission systems deliver energy from generating facilities to distribution systems for final delivery to customers. PGE schedules energy deliveries over its transmission system in accordance with FERC requirements and operates one BAA in its service territory. In 2024, PGE delivered approximately 31 million megawatt hours (MWh) through 1,269 circuit miles of transmission lines operating at or above 115 kilovolts (kV).
PGE’s transmission system is part of the Western Interconnection, the regional grid in the western United States. The Western Interconnection includes the interconnected transmission systems of 11 western states, two Canadian provinces and parts of Mexico, and is subject to the reliability rules of the WECC and the NERC. PGE relies on transmission contracts with BPA) to transmit a significant amount of the company’s generation to serve its distribution system. PGE’s transmission system, together with contractual rights on other transmission systems, enables the company to integrate and access generation resources to meet its customers’ energy requirements. PGE’s transmission system is managed on a coordinated basis to obtain maximum load-carrying capability and efficiency. PGE has joined the Western Power Pool’s resource adequacy program known as the Western Resource Adequacy Program (WRAP), which is expected to become a binding commitment in 2027. The company has participated in the western EIM for several years and plans to join the CAISO Extended Day Ahead Market (EDAM) in the near future.
The company’s wholesale transmission activities are regulated by the FERC and are offered on a non-discriminatory basis, with all potential customers provided equal access to PGE’s transmission system through PGE’s OATT. In accordance with its OATT, PGE offers several transmission services to wholesale customers, including:
Network integration transmission service, a service that integrates generating resources to serve retail loads;
Short- and long-term firm point-to-point transmission service, a service with fixed delivery and receipt points; and
Non-firm point-to-point service, an as available service with fixed delivery and receipt points.
Environmental Matters
PGE’s operations, primarily its thermal generating plants, are subject to regulation under the federal Clean Air Act (CAA), which addresses particulate matter, hazardous air pollutants, and GHG emissions, in terms of both quantity and rate, among other things. Oregon and Montana, the states in which PGE’s thermal facilities are located, also implement and administer certain portions of the CAA and have set standards that are at least as stringent as federal standards. PGE manages its air emissions at its thermal generating plants by the use of low sulfur fuel, emissions and combustion controls and monitoring, and sulfur dioxide allowances awarded pursuant to the CAA.
PGE works continually with state agencies to obtain permits or certificates of compliance needed for its hydroelectric operations under the FERC licenses and continues to monitor and update equipment to meet federal and state standards.
PGE continues to implement fish protection measures at its hydroelectric projects that were prescribed by the U.S. Fish and Wildlife Service and the National Marine Fisheries Service under their authority granted in the ESA and the FPA. Conditions required with the operating licenses are expected to result in a minor reduction in power production and continued capital spending to modify the facilities to enhance fish passage and survival.
The handling and disposal of hazardous materials from Company facilities is subject to regulation under the federal Resource Conservation and Recovery Act.
PGE is also subject to the Comprehensive Environmental Response Compensation and Liability Act, commonly referred to as Superfund, which provides authority to the EPA to assert joint and several liability for investigation and remediation costs for designated Superfund sites.
PGE is subject to regulation by the United States Department of Energy (USDOE), which, under the Nuclear Waste Policy Act of 1982, is responsible for the permanent storage and disposal of spent nuclear fuel. PGE has contracted with the USDOE for permanent disposal of spent nuclear fuel from Trojan that is stored in the Independent Spent Fuel Storage Installation (ISFSI), an NRC-licensed interim dry storage facility that houses the fuel.
Federal Regulation
Several federal agencies, including the Federal Energy Regulatory Commission (FERC), the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA), and the Nuclear Regulatory Commission (NRC), have regulatory authority over certain aspects of PGE’s operations and activities, as described in the discussion that follows.
PGE is a licensee, a public utility, and a user, owner, and operator of the bulk power system,” as those terms are defined in the Federal Power Act (FPA). As such, the company is subject to regulation by the FERC in matters related to wholesale energy activities, transmission services, reliability and cybersecurity standards, natural gas pipelines, hydroelectric projects, accounting policies and practices, short-term debt issuances, and certain other matters.
Wholesale Energy—PGE has authority under its FERC Market-Based Rates tariff to charge market-based rates for wholesale energy sales in all markets in which it sells electricity except in its own Balancing Authority Area (BAA). The BAA is the area in which PGE is responsible for balancing customer demand with electricity supply, in real time, and the tariff exception within PGE’s BAA does not have a material impact on the company.
Transmission—PGE offers wholesale electricity transmission service pursuant to its Open Access Transmission Tariff (OATT), which contains rates, terms, and conditions of service, as filed with, and approved by, the FERC.
Reliability and Cybersecurity Standards—The FERC has adopted mandatory reliability standards for owners, users, and operators of the bulk power system. Such standards, which are applicable to PGE, were developed by the North American Electric Reliability Corporation (NERC) and the Western Electricity Coordinating Council (WECC), which have responsibility for compliance and enforcement of these standards, and are intended to help maintain and strengthen the reliable planning and operation of the bulk power system.
Natural Gas Pipelines—The FERC has authority in matters related to the construction, operation, extension, enlargement, safety, and abandonment of jurisdictional interstate natural gas pipeline facilities, as well as transportation rates and accounting for interstate natural gas commerce. PGE is subject to such authority as the company has a 79.5% ownership interest in the Kelso-Beaver (KB) Pipeline, a 17-mile, 20-inch diameter, interstate pipeline that provides natural gas to the company’s three natural gas-fired generating plants located near Clatskanie, Oregon: Port Westward Unit 1 (PW1); ii) Port Westward Unit 2 (PW2), and Beaver. In addition, the KB Pipeline serves the North Mist storage facility, which is owned and operated by a local natural gas distribution company, and one additional delivery point for a local manufacturing concern. As the operator of record of the KB Pipeline, PGE is subject to the requirements and regulations enacted under the Pipeline Safety Laws administered by the PHMSA, which include safety and operator qualification standards and public awareness requirements.
Hydroelectric Licensing—As required under the FPA, PGE holds FERC licenses for all Company-owned and operated hydroelectric generating plants. The FERC license process includes an extensive public review that involves the consideration of numerous natural resource issues and environmental conditions.
Short-term Debt—Pursuant to applicable provisions of the FPA and FERC regulations, regulated public utilities are required to obtain FERC approval to issue certain securities.
Spent Fuel Storage—The NRC regulates the licensing and decommissioning of nuclear power plants, including PGE’s decommissioned Trojan nuclear power plant (Trojan), which was closed in 1993.
State Regulation
PGE is subject to the jurisdiction of the OPUC, which reviews and approves the company’s retail prices and reviews the company’s generation and transmission resource acquisition plans, pursuant to a biennial integrated resource planning process. In addition, PGE is required to create a Clean Energy Plan (CEP) to be filed in connection with the company’s Integrated Resource Plan (IRP) that articulates the company’s strategy to meet emission reduction targets through an equitable transition to a decarbonized grid. The OPUC also regulates the issuance of securities, prescribes accounting policies and practices, regulates the sale of utility assets, reviews transactions with affiliated companies, and has jurisdiction over the acquisition of, or exertion of substantial influence over, public utilities.
Retail customer prices are determined through formal public proceedings that generally include testimony by participating parties, discovery, public hearings, and the issuance of a final order by the OPUC. Participants in such proceedings may include PGE, OPUC staff, and intervenors representing PGE customer groups, as well as other interested parties. The following lists the more significant regulatory mechanisms and proceedings under which customer prices are determined:
