Brookfield closed its acquisition of the 17.9MW plant earlier this year after agreeing a deal with the previous owner, Ford Motor Co, in mid-2007. It generates approximately 97GWh of electricity annually.
The plant, on the Mississippi river, holds four Francis turbines in the powerhouse that is integral with a US Corps of Engineers dam, which consists of twin lock chambers and a central concrete spillway. It is operated in run-of-river mode.
LIHI said no further works were planned at the plant. Brookfield has plans for another plant downstream of Twin Cities, and it is expected to have an installed capacity of 10MW.
Deadline for comment to LIHI on the application is 30 January 2009.
The company's Black River scheme was certified previously by LIHI, which has noted that Brookfield is its most active client.
Separately, in late October, LIHI re-certified Hydro Energy Development Corp's Black Creek plant, near Seattle, Washington state. The plant has an installed capacity of 3.7MW and average annual generation is 10GWh.
