Building exterior

The Automatic hydroelectric plant (Automatic) was originally constructed in 1924 and is located approximately 5 miles downstream of Rice Rips hydroelectric plant (FERC No. 2556, LIHI Project No. 59).  The project consists of: (1) an 81-foot-long, 33-foot-high concrete gravity dam with (a) a 33-foot-long nonoverflow section, (b) a 20-foot-long by 2-foot-wide gated section with one Taintor gate, 14 feet high by 16 feet wide, (c) a 30-foot-long spillway section topped with 2-foot-high flashboards, (d) an intake section beneath the spillway and (e) an earthen section containing a 30-foot-long retaining wall; (2) a concrete and brick powerhouse, 63 feet high by 19 feet wide by 31 feet long, housing one horizontal Francis turbine and General Electric generator combination with a rated capacity of 800 kW; (3) a 4.5-mile-long impoundment with a gross storage capacity of 900 AF; and (4) appurtenant facilities.

Project Name Automatic
LIHI Certificate Number 72
LIHI Effective and Expiration Dates February 14, 2011
February 14, 2016
(extended to June 30, 2017)
Owner Kennebec Water District
State Maine
Location Located on the Messalonskee Stream in Oakland and Waterville, Maine.
Installed Capacity 0.800 MW
Average Annual Generation 2.7 GWh
Facility Type Inflow > 570 cfs: run-of-river
Inflow < 570 cfs: cycled
FERC No. 2555

Operation of Automatic is dependent on inflow to Messalonskee Lake and discharge from the upstream Oakland and Rice Rips Hydroelectric projects. When inflow to Messalonskee Lake is greater than approximately 570 cfs, Automatic is operated as a run-of-river project. When inflow is less than approximately 570 cfs the project is cycled. Fifteen cfs is discharged at all times through the Automatic project as well as the upstream Oakland and Rice Rips hydroelectric projects and the downstream Union Gas hydroelectric project. All additional water that does not go through the turbines is discharged over the spillway.

Certification History

December 16, 2016: The Automatic Project has been granted a third extension of the current certificate term.  The new expiration date is June 30, 2017. See the extension letter for explanation below.

August 5, 2016: On July 6, 2016, the Low Impact Hydropower Institute received a complete application for a new term of Low Impact Certification for the Automatic Hydroelectric project.  The application materials can be found in the Files section below.

LIHI is seeking public comment on this application.  Specifically, we are interested in knowing whether you think the Automatic project continues to meet the LIHI Low Impact Certification Criteria.  Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s 2016 application materials posted on the project page.  Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered.  Comments may be submitted to the Institute by e-mail at comments@lowimpacthydro.org with “Automatic Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, PO Box 194, Harrington Park, New Jersey 07640.  Comments must be received at the Institute on or before 5 pm Eastern time on October 5, 2016 to be considered.  All comments will be posted to the web site and the applicant will have an opportunity to respond.  Any response will also be posted.

July 1, 2016:  The Automatic Project has been granted an additional extension of the current certificate term as it prepares to apply for a new term.  The new expiration date is December 31, 2016. See the extension letter for explanation below.

December 22, 2015: The Automatic Project has been granted an extension of the current certificate term. The new expiration date is August 19, 2016. See the extension letter for explanation below.

May 26, 2011: The Automatic Hydroelectric Project has been certified as low impact for a five year term, effective February 11, 2011 and expiring February 11, 2016, with the following condition:

  • Within 12 months of the date of issuance of the LIHI certification for the Automatic facility, the applicant shall present to LIHI a copy of an agreement with the Maine Department of Marine Resources and the US Fish and Wildlife Service (“Agencies”) in which the applicant and agencies have reached agreement on the final design, construction, operations, and maintenance of safe, timely, and effective upstream and downstream passage for American eel at the Automatic facility, along with a similar agreement executed between the owners of (a) the Union Gas facility and (b) the Messalonskee Lake outlet dam (owned by Messalonskee Stream Hydro, LLC, and the agencies for upstream and downstream passage for American eel at these two facilities as well. This 12 month deadline at the Automatic facility may be extended for an additional 6 months if the applicant can demonstrate to the agencies that field work necessary to determine the appropriate location and design of fish passage at the Automatic facility necessitates this extension. This agreement shall include a date to initiate construction of the required upstream and downstream passage at the Automatic facility that is the same date as installation required at the downstream Union Gas facility and the Messalonskee Lake outlet dam, unless the applicant can demonstrate to LIHI that such a deadline is infeasible, in which the deadline for construction at the Automatic facility shall be no later than 12 months after the date on which the agreement is reached.

April 15, 2011: LIHI received a comment package containing four separate from Douglas Watts, of the Friends of the Kennebec Salmon. In addition to the four documents, Doug Watts sent an email explanation for including the Connectivity Report, all of which can be found in the Files section below.

April 14, 2011: Public comment period on the application for certification has been closed.

February 19, 2011: LIHI received a comment letter from Doug Watts, of the Friends of the Kennebec Salmon. A PDF version of the letter can be found in the “Files” section below.

February 14, 2011: Kennebec Water District has submitted an application for the certification of the Automatic Project.
