Twin Cities Hydro Project Seeks LIHI CertificationSubmitted by Rupak Thapaliya on Tue, 2008-12-02 11:33
The twin cities hydropower project located at the Mississippi Lock and Dam No. 1 (P-362) in St. Paul, MN is seeking to be certified as a low-impact project under the Low Impact Hydropower Institute's (LIHI) certification criteria.
The 17.92 MW project was licensed by FERC in November 2004 and is located within the Mississippi National River and Recreation Area (MNRRA).
According to the application for certification, the project consists of
- a 156- foot-long by 112-foot-wide powerhouse integral with the Corps' dam, containing four 5,800-hp Francis turbines and four 4,480-kW generating units with a total installed capacity of 17,920 kW; and,
- a two-foot-high inflatable rubber flashboard system on top of a 574-foot-long concrete spillway dam with a crest elevation of 723.1 feet mean sea level (msl).
LIHI is now accepting public comments on the application by Brookfield Power, which owns the project.
LIHI evaluates a hydroproject on the following eight criteria before issuing certification:
- river flows,
- water quality,
- fish passage and protection,
- watershed protection
- threatened and endangered species protection,
- cultural resource protection,
- recreation, and
- facilities recommended for removal.
Since 2001, the Institute has issued LIHI certification to 36 projects around the nation.
