FERC relicenses Texas-Louisiana hydro project, OKs expansion and exemption of Oregon projects

The Federal Energy Regulatory Commission relicensed a Texas-Louisiana hydropower project, authorized expansion of an Oregon project and approved an Oregon conduit exemption during August.

The Energy Infrastructure Update for August 2014, compiled by FERC’s Office of Energy Projects, features relicensing of the Toledo Bend hydroelectric project (No. 2305) on the Sabine River on the Texas-Louisiana border. The Toledo Bend relicense adds a new 1.3-MW minimum flow unit to the project for total installed capacity of 82.3 MW.

In their relicense application, joint licensees Sabine River Authority of Texas and the Sabine River Authority, State of Louisiana, proposed to construct a 1.3-MW horizontal Francis minimum flow turbine-generator in a second powerhouse downstream of the Toledo Bend spillway.

FERC also issued a license amendment to Portland General Electric allowing the utility to utilize minimum flow turbine-generators to expand by 3.89 MW the 136.6-MW Clackamas River hydroelectric project (No. 2195) on Oak Grove Fork and the Clackamas River in Clackamas County, Ore.

The amendment authorizes PGE to construct: a powerhouse at the base of Timothy Lake Dam housing two 950-kW turbines; a powerhouse at Crack-in-the-Ground downstream of Lake Harriet housing a 1-MW turbine; a powerhouse housing a 135-kW turbine utilizing return flows from the juvenile downstream migrant collection systems and the North Fork fishway adult fish trap; and a turbine and an 850-kW turbine and induction generator utilizing North Fork fishway attraction flows.

Also in Oregon, FERC issued a conduit exemption to Monroe Hydro LLC for the 300-kW Monroe Drop hydroelectric project (No. 14430) on the North Unit Irrigation District’s main canal in Jefferson County, Ore. Under terms of the Hydropower Regulatory Efficiency Act of 2013, for the first time FERC was able to grant the conduit exemption for a project located on federal lands, a Bureau of Reclamation irrigation canal.

In other action, the commission received an application to license the 5-MW Delta hydro project (No. 13135) at an existing New York State Canal Corp. dam on the East Branch of the Mohawk River in Oneida County, N.Y. The applicant city of Watervliet, N.Y., previously filed an application for the project in 2011, at that time seeking a 5-MW (maximum) small hydro exemption.

FERC, which previously used the infrastructure update as an in-house tool, began making the monthly update public beginning with December 2010. The report allows the public to track the activities of the Office of Energy Projects in the areas of hydropower, natural gas, electric generation, and electric transmission.
