IMPORTANT! At its complete discretion, and in order to better reflect true energy savings as a result of a project, the Program may use the change in kilowatt-hours required to pump an acre-foot of water in conjunction with the number of acre-feet pumped as the basis for calculating the potential incentive rebate.

INSTRUCTIONS:

1. Calculate the Potential Rebate based on energy savings in Section A. There is an example of how to do the calculations for Method 2 at the bottom of the Certificate of Completion page. Note the requirements for providing utility billing records. If you can not find the last 12 months' bills showing kilowatt-hour usage, call the following numbers to obtain a record:
   • If you are a Pacific Gas and Electric Company customer - (800) 468-4743
   • If you are a Southern California Edison Company customer - (800) 990-7788
   • If you are a San Diego Gas and Electric Company customer - (800) 411-7343
2. Calculate the Potential Rebate based on 50% of the estimated project cost in Section B (it is not critical to know the project cost exactly if preparing the application before the project is completed).

Your estimated incentive rebate is the lower of the Potential Rebates calculated in Section A and Section B -

Enter the lower number as your Potential Rebate here $ _________________

Section A - Incentive Calculation from Energy Savings
Previous 12 months kWh usage (Annual kWh in equations below): _________

Method 1 - Use this method if the before-project pump test indicates an overall pumping plant efficiency less than or equal to 50% (40% if a submersible - type pump) and you retrofit/repair either or both of the impeller and bowl of the pump.

Potential Rebate = .10 X .25 X Annual kWh = $_________
Potential Rebate = .10 X .25 X _________ = $_________

Method 2 - Use this method if the pre-repair efficiency test indicates an overall pumping plant efficiency greater than 50% (40% if a submersible pump), or you are NOT retrofitting/repairing the bowl and impeller.

The following are requirements for submitted pump efficiency tests when using this Method. Note that the Program reserves the right to audit the after-repair test using an independent pump test company:

• If this is a water well, the pump test must be at similar discharge pressures (+/- 5 psi of the before-repair discharge pressure) and with a similar standing water level (+/- 10% of the before-repair level).
• If this is a booster pump, either a) the same pump and impeller trim (if applicable) must be in place before and after the repair/retrofit or b) the tests are at the same operating condition (+/- 10% of before-repair flow and total dynamic head).

  a. Enter the pre-repair operating plant efficiency: ________________. This is "Pre-OPE" in the equation below.

  b. Enter the estimated after-repair operating plant efficiency: ______. This is "Post-OPE" in the equation below.

Potential Rebate = .10 X (Annual kWh - (Annual kWh X Pre-OPE / Post-OPE))
Potential Rebate = .10 X (_________ - (_________ X ________ / _______)) = ________

Section B - Incentive Rebate Rebates from Project Cost
Enter the estimated Project Cost: _________. This is "Project Cost" in the equation below.

Potential Rebate = .50 x Project Cost
Potential Rebate = .50 x _________ = $ ______
