Hydropower is America’s leading renewable energy resource. Of all the renewable power sources, it is the most reliable, efficient and economical. Western markets and delivers about 10,000 megawatts of reliable, cost-based hydropower from powerplants at 56 Federal hydropower plants and one coal-fired plant to rural electric cooperatives, municipalities, public utility districts, Federal and state agencies, Native American tribes and irrigation districts.
The main products Western offers to our customers are:
Through our Power marketing services, Western sells capacity—the demand of electricity, measured in kilowatts—and energy—the amount of electricity delivered over time, which is measured in kilowatthours. Products include:
- Long-term, firm power and other long-term sales—Firm power is capacity and energy that Western guarantees to be available 24 hours a day. Western also sells contingent, or withdrawable capacity. Contingent capacity is sold to customers who agree that the capacity may be unavailable at times. The customer is responsible for replacing the capacity that is withdrawn or otherwise unavailable.
- Non-firm energy and short-term sales—Non-firm energy is sold to utilities that prefer not to use an expensive fuel or to make expensive purchases from another seller. The customer pays only for the energy delivered, since it has the capacity to meet its load, if necessary.
- Seasonal sales—Customers may purchase power generated or made available only during certain seasons of the year.
- Purchase power—Western must buy power from other suppliers when we do not have enough Federal generation available (due to bad water conditions or operational constraints) to meet our contract commitments. Power may also be purchased to support short-term sales.

Transmission services allow other utilities to use Western’s transmission system to transmit non-Federal power. Services include:
- Point-to-point transmission—Firm point-to-point transmission service is transmission service between points of receipt and delivery. Long-term, firm point-to-point is service for one year or more. Less than one year is considered short-term. Non-firm point-to-point service is provided on an as-available basis and can be interrupted.
- Network integration transmission service—This service allows customers to dispatch their designated resources to loads (their customers) over Western’s system. Network customers using this service must obtain certain ancillary services from the control area operator or the transmission provider.
Ancillary services are services that support the transmission of capacity and energy from resources to loads while maintaining reliable system operation. Services include:
- Scheduling, system control and dispatch services—Scheduling the amount of energy to be delivered, assigning load and ensuring operational security.
- Reactive supply and voltage control from generation sources service—Maintaining correct voltage through adjustments to generator output.
- Energy imbalance service—Providing energy correction for any hourly mismatch between a transmission customer’s energy supply and demand served.
- Regulation and frequency response services—Following the moment-to-moment variations in the demand or supply in the control area.
- Operating reserve - spinning reserve service—Providing immediate back-up service from a reserve unit to serve load in case of a system contingency.
- Operating reserve – supplemental reserve service—Serving loads when a contingency exists; not available immediately to serve load but can be available within a short time.
