The Federal Energy Regulatory Commission dismissed a petition today that would have overridden state ability to enforce water quality standards—a right that has been codified by the Supreme Court. The ruling was a win for IRU and other conservation groups that are seeking better water quality standards at three Idaho Power Co. dams on the Snake River in Hells Canyon.
A Canadian company has proposed to build a new hydroelectric facility at Daguerre Point Dam on the South Yuba River in California. Earlier this year, the National Oceanic and Atmospheric Administration (NOAA) had determined that continued operation of the dam will jeopardize endangered fish species on the Yuba River.
Public Service Company of New Hampshire (PSNH) is a vertically integrated public utility that owns and operates nine hydroelectric projects in New Hampshire totaling approximately 70 MW. PSNH’s 1.1 MW Canaan Project is located on the upper Connecticut River in the states of New Hampshire and Vermont. The relicensing of this project was one of seven “pioneer” projects electing to utilize the Federal Energy Regulatory Commission’s (FERC or Commission) new Integrated Licensing Process (ILP) during the initial transition period.During the ILP scoping process, resource agencies and intervenors requested that PSNH study the feasibility of upstream fish passage at the Canaan Project. There are no Atlantic salmon or other migratory fish in the project area: upstream fish passage was proposed for indigenous brook, and non-native brown and rainbow trout and other non-migratory resident fish. A standard Denil fishway and an Alaska Steeppass were determined to be technically feasible options and were evaluated for economic feasibility by PSNH’s consultant, Kleinschmidt Associates
A simulation model was created to identify dam operations and configurations that provided high survivals for Juvenile salmonids migrating out of the Snake River. Regional fisheries managers sought to identify ways to operate and configure the dams and the fish transportation system (barging) to provide safe passage conditions and survival rates that met or exceeded criteria set forth in the Biological Opinion. The challenge was to determine whether a candidate operation or construction item provided the expected survival benefits when the operations and configurations of the entire system were considered. The expected influence of candidate operations and configurations was simulated to screen many millions of combinations and identify the subset that met minimum criteria. Acceptable combinations exhibited a range of survival values, construction costs, and power revenues. This approach provided a set of cost effective combinations from which a mix of survival benefits, construction costs, and power revenues could be chosen to meet stewardship goals.
