The Project - Hydroelectric Plant, Substation & High Voltage Lines

At a public meeting held August 26, 2014 in Auburn,California, the project proponents (links below) described the proposed project facilities and operations, and the Federal Energy Regulatory Commission’s Traditional Licensing Process. The Traditional Licensing Process is described on the Federal Energy Regulatory Commission’s website

A number of local residents voiced concerns about the project's impacts to the Auburn State Recreation Area and the American River canyon. These included (but were not limited to) recreation, public safety, environmental degradation, visual and noise impacts, construction issues, and interrupted access to the public's use of the State Park.

The concept:  Build a CANAL near the boat ramp, add a POWERHOUSE down the side of the canyon and a MAJOR ELECTRICAL SUBSTATION with HIGH VOLTAGE LINES spanning the canyon, climbing out of the canyon near Bell Road to connect to the PG&E Halsey Powerhouse along Dry Creek Road.

Excerpts from the proponents' website:

Description of the project

The Lake Clementine Hydroelectric Project is a 16 MW, 47 GWh annual average generation, run-of-river hydroelectric project. The project is being developed at an existing U.S Army Corps of Engineers dam. It is located at the North Fork Dam, on the American River, just east of the City of Auburn, in Placer County, California. (Click here for more information about the area on the California government website.)

Lake Clementine Hydro, LLC has Preliminary Permit number P-13432 from the Federal Energy Regulatory Commission (FERC). The project is in the pre-filing Stage 2, of three stages, under the FERC Traditional Licensing Process. Lake Clementine Hydro is working with the U.S. Army Corps of Engineers to coordinate this development. The conceptual design has been concluded on the project, a Pre-Application Document and Notice of Intent have been submitted to FERC.

As mentioned, the project will be incorporated into the existing U.S. Army Corps of Engineers’ North Fork Dam to generate electricity for the first time since its construction in 1939 and consists of:

  1. a new intake and penstock,
  2. a new powerhouse downstream of the dam,
  3. a new switchyard,
  4. 2-3 turbine/generator units with a total installed capacity of 16 megawatts,
  5. a new transmission line extending from the switchyard to an interconnection point with PG&E’s distribution system, and
  6. appurtenant facilities.

At this stage of development, the selection of the type or size of the turbine-generators has not been finalized. It is anticipated that the Lake Clementine Project will use either Francis or Kaplan turbines connected to two or three generators. The final plant configuration is being discussed with the US Army Corps of Engineers.
