The Northwest Power Pool serves as a forum for reliability and operational adequacy issues in the area for both transmission and generation

Under section 10(f) of the Federal Power Act, an owner of a hydropower project is required to reimburse upstream headwater project owners for an equitable part of the benefits it receives. These benefits, referred to as Headwater Benefits, are the additional energy production possible at a downstream hydropower project resulting from the regulation of river flows by an upstream storage reservoir.
All parties with a right to coordinated storage releases from upstream reservoirs in the United States have the obligation to make payments to the owners/operators of the upstream reservoirs.
The payments are to cover a portion of the maintenance costs related to storage paid by the upstream party that provide a benefit to the downstream party.
Owners/operators provide the annual costs for each reservoir, and the portion of these costs that is apportioned to the storage function is calculated:
“P” values are derived from the Final Regulation, which determines the Firm Energy Load Carrying Capability of each project for the year.
“A” values are the average derived form a 70-year, non-continuous study that uses the beginning levels of storage as determined by the Actual Energy Regulation as the initial values for each year of the study.
