Watterra Energy seeks FERC permit for hydroelectric project in Indiana

Watterra Energy LLC on Dec. 30 applied to the Federal Energy Regulatory Commission for a preliminary permit allowing up to three years of exclusivity for project feasibility work on the proposed Brookville Dam Hydroelectric Project in Indiana.

The proposed project is located at the Brookville Lake Dam of the U.S. Army Corps of Engineers (USACE). It is located 0.75 miles north of the City of Brookville on the East Fork of the Whitewater River in Franklin County, Indiana. The construction of the existing dam was completed in 1974 with a main purpose of flood control and storm water management. The total storage in the Brookville Lake is 184,900 acre-feet, and covers an area of 8.2 square miles at the normal operating level (El 748 feet m.s.l.).

This is an earth fill dam with a damming height of 181 feet with a crest length of 2,800 feet. The outlet works of the dam are located near the right abutment and pass through the dam in the floor of the river valley.

Watterra Energy is proposing to construct a new powerhouse downstream of the existing dam to accommodate a hydroelectric system with a design head of 110 feet. The proposed project will consist of twin horizontal Francis turbines connected to a single generator. Each turbine will have a nominal capacity of 2.2 MW (4.4 MW combined). The expected annual average generation of the project is 23,250 MWh. The proposed project will operate strictly in “run-of-the-river” mode. The exact type, number, capacity, and arrangement of the turbine units and proposed structures may be modified following further advancement of design studies and engineering.

The project will include a new 400-foot-long, 14.7-kV transmission line. It is anticipated at this time that the project would interconnect with an existing distribution system at a nearby Cinenergy/Whitewater REA Substation.

FERC would expect the company to work on preparation of a license application for this project during the three-year permit term.
