LIVERMORE MINIMUM FLOW UNIT
International Paper Company
Jay, ME
The minimum flow project at the Livermore
Hydroelectric Station provides a means to bypass
the flow required by the FERC license and
generate electricity from the flow discharged at
the end of the forebay. The forebay will serve as
an intake to a new powerhouse on the riverside of
the existing powerhouse. The new structure will
include a single vertical Kaplan unit with a
vertical generator and required appurtenances.
The new machinery will have a design flow
capacity of 510 cfs with an output capacity of
1320 Kilowatts.
The new development will be attached to the existing facilities on the south side of the Livermore Station’s forebay. The new intake, forebay, powerhouse, and tailrace will be at a 30-degree angle from the existing forebay flow lines. Additional excavation in the river will be required to redistribute the discharge flows across the lower portion of the bypass reach.
The minimum flow discharge requirement includes two separate time frames with two components for each time. The bypass flow spilled at the dam must be at least 150 cfs in May, June, and October. For the same period the discharge from the minimum flow unit has to be at least 400 cfs. For January through April, July through September, and November and December the spillage at the dam must be at least 100 cfs.
Kleinschmidt provided conceptual design services during the relicensing effort. Since issuance of the new license, Kleinschmidt has completed the feasibility assessment which included multiple options.
