The Wells Hydroelectric Project has ten generating units. Each unit has, among other things, a rotor made up of poles of magnets which turns inside of a stationary stator which is made of coils of copper. These units convert the pressure of water on turbine blades into electricity. The generating units received new stator windings in the mid 1970s and have been operating reliably ever since.
A fault occurred in Generator Unit One on February 12, 2005. A fault is when electricity takes a path it is not intended to go. In this case, the fault caused damage to the metal parts of the generator. We performed various diagnostic tests and assessments with the hope of repairing the damage and returning the unit to service with a reduced rating.
We have now determined that the only practical course is to replace the stator winding with new coils, restack the stator core with new electrical steel and re-insulate and refurbish the rotor poles (rewind the generator). Your Commissioners authorized a call for bids to rebuild Generator Unit One. We anticipate that Generator Unit One will be returned to service in early 2006.
Thirty years is a long time for a generating unit to perform. Therefore, due to the age and test results from the other nine units, we have decided to rewind all ten generating units to avoid an unexpected outage of a unit.
Douglas PUD will be selling bonds in July to cover the costs of refurbishment work for all ten generating units. By doing so, we are able to offer reasonable power rates and keep the Wells Hydroelectric Project running smoothly well into the future.
It doesn’t take money to save money on summertime energy bills. Here are some things you can do for free to slash your electric bill:
Raise your thermostat by two degrees to reduce your cooling costs by up to five percent.
Clean or change air conditioning filters monthly. Dirty filters cause air conditioners to work harder and use more energy.
Remove dust from the coils of your refrigerator and freezer so they operate more efficiently.
Close your blinds during the heat of the day and open your window during the cool evening to give your air conditioner a rest.
Turn off heat-producing lights and home computers when not in use.
Fire up the barbecue grill to move cooking outdoors.
Adjust your dishwasher so dishes dry without heat.
