If the turbine and generator were operating at their minimum capacity for one day, the cost savings would be:

Minimum Daily Cost Savings = (.5) 62.5 KW x 24 hours/Day x .0853 $/KWH

       = $67.04 / Day


The following is a summary of the activities required to generate electricity at the Pettibone Creek Hydroelectric station:

  1. Turbine and Plant Inspection
  1. The existing turbine casings and draft tubes should be inspected by someone knowledgeable in the business to determine if they are still in suitable condition for reactivation.
  1. A report needs to be prepared with the results of the inspection and an outline of the specific tasks and costs required for the reactivation of the equipment.
  2. The James Leffel Company, who was the original manufacturer of the turbines, has provided a proposal to perform these tasks for a cost of $2,800.00.
  3. Mr. Frank Christie, PE is a consulting engineer with Wolverine Power & Electric.  Mr. Christie is part owner and operator of five hydroelectric generating facilities.  He has also provided a proposal to inspect and evaluate the powerhouse for a cost of $7,500.  This fee includes the feasibility study and licensing application requirements outlined below.

2. Study and Licensing Requirements

  1. All hydroelectric generating units have to be registered with the Federal Energy Regulatory Commission (FERC) for licensing or obtain an exemption.  This facility would qualify for an exemption due to its small size.  Since the power generated will not be sold, it is possible the FERC may not even require an exemption.
  1. Along with the application the appropriate environmental information is required and jurisdictional approvals would have to be obtained.
  2. The water power rights also need to be confirmed.

3. Turbine and Generator Installation

  1. Install new turbine runner, shaft and wicket gates in existing housing.
  1. Design, fabricate and install structural steel support for generator.
  2. Install 480 V, 3 phase generator and controls
  3. Another option, proposed by HPB Hydroelectric Inc., is to install a new skid mounted turbine/generator package and connect to the existing piping.

4. Synchronizing and Power Flow Control Equipment

  1. Design and install controls to allow the paralleling of power sources and to regulate the flow of power.
  1. Utilize existing SCADA system at the well house for monitoring and control.

5. Power Distribution Equipment

  1. Install new power distribution panel in the powerhouse.
  1. Install 480/120 V step down transformer and receptacle panel for the powerhouse electrical service.

6. Conduit and Wire to Well House

  1. Install underground conduit and wire from the powerhouse to the well house for the power distribution and control wiring.
  1. A portion of the installation would have to be directionally bored to minimize disruption to the park.

7. Flume Vent at Rite Aide

  1. Approximately midway on the flume, a 36” welded steel vent pipe was connected to the flume and ran up to approximately six feet above grade.  It is presently located in the parking lot at Rite Aid Pharmacy on the corner of Main Street and Summit Street and has been cut down to grade level.  A watertight cover would have to be installed to prevent leakage when the flume is filled.


Once the building is renovated, general maintenance will be required to keep it in good operating condition.  The following is a summary of the maintenance requirements for the building and hydroelectric equipment:

1. Building and Site Maintenance

  1. Mowing and Landscape Maintenance
  1. Snow removal
  2. Heating Ventilation and Air Conditioning
  3. Miscellaneous Building Maintenance

2. Hydroelectric Equipment Operation and Maintenance

  1. Labor for equipment operation and monitoring
  1. Labor for equipment maintenance
  2. Miscellaneous materials and supplies
