The educational and technical assistance components of APEP are free and available to anyone. However, there are eligibility factors that must be satisfied to receive a subsidized pump test or the cash incentive for retrofit of a pump. There are three types of eligibility:  account eligibility, pump eligibility, and retrofit incentive eligibility.

  1. Account Eligibility (as of January 1, 2018) – The basic account eligibility statement is:

Eligibility extends to all owners or users of a non-residential, PG&E electric or natural gas utility account that is primarily used for pumping water for production agriculture, landscape or turf irrigation, or municipal purposes, including potable and tertiary-treated (reclaimed) water but excluding pumps used for industrial processes, raw sewage, or secondary-treated sewage, and who are paying the Public Purpose Programs Charge. Customers should call APEP first if there is a question concerning their eligibility.

  1. Eligibility Statement for Subsidized Pump Efficiency Tests (as of January 1, 2018) –

Subsidized pump tests must be performed by APEP participating pump test companies. The pump test subsidy is paid to the test company, not you. Currently the standard subsidy is $100/test for pumps not tested in the 23 months prior to the test date. The subsidy is $50/test for pumps that are in series with another pump (most commonly a booster pump being supplied by a water well). These subsidies may or may not cover the total cost of the test. You should have a clear understanding of the total cost of a pump test, and whether you will be liable for any part of that cost, before you authorize a test.

To be eligible:

  • The pump test must be for the purpose of determining current overall pumping efficiency (OPE).
  • Only one subsidized test is allowed per pump in a 23-month period.
  • You will have to sign an Access Agreement before the test so that the pump tester has legal access to your property. You will have to sign a Record of Test after the test so that there is proof a test was performed for you.
  • Subsidized pump tests are not available for any purpose related to:
    • A real estate transaction (e.g., determine flow, pumping water level, water quality).
    • Satisfaction of a mandate of any federal, state, or local government or quasi-political agency (participants in PG&E’s AG-ICE program are specifically eligible for all parts of APEP).
  • Subsidized pump tests are not available for the following conditions:
    • A pump which is in the APEP database already which was previously tested at 30% OPE or less for electric and submersible pumps and 6% OPE or less for natural gas-powered pumps, unless that pump was retrofitted in the interim.
    • Water wells or any other pump where the true total dynamic head cannot be determined. APEP requires that a subsidized pump test be able to calculate overall pumping efficiency (OPE).
    • Any pump powered by less than 25 horsepower as listed on the motor/engine nameplate.
  1. Eligibility Statement for the Retrofit Incentive (as of May 29, 2019) –

Cash incentives are available for retrofit of eligible pumps in order to improve pumping efficiency. Eligibility factors include:

IMPORTANT! APEP requires a pump efficiency test be performed prior to and after the retrofit project.  They do not have to be done by APEP testers but they must be considered accurate by APEP. These tests cannot be more than three (3) years apart, except when the pre-project test does not include a calculated Overall Pumping Efficiency. In this case, three (3) tests within six (6) years prior to the project start date, as identified on the application, must be submitted.  APEP can accept applications for retrofit incentives after the project is completed but the application must be completed within two (2) years after the post-project test. This includes submittal of copies of the pre- and post-project pump tests, invoices, the completed and signed application form, and the completed and signed Certificate of Completion.

Work can be contracted or performed wholly or partially in-house if such capability exists.  However, in-house labor rates and other costs cannot exceed the average of rates and costs charged by the two closest commercial pump service contractors.

Incentives from APEP cannot be combined with other utility grant, rebate, or service programs, or with grants, rebates or services offered by any other state or local government agency for the same measure.

In addition, eligible projects must satisfy the following criteria:

  • The pump must be operational at the time of retrofit. APEP will not provide an incentive for an inoperable pump.
  • The specific work must include:
    • replacement of either or both of the pump bowl and impeller or,
    • machine work (e.g., re-facing, pit and hole filling) to return either or both of the pump bowl and impeller to original condition or,
    • trimming impellers to better match required operating conditions.
  • Only one pump, with one discharge point, is eligible per application. (A well with a booster pump located at the well, and in series with the well, is an eligible pumping system for retrofit of either the well or the booster pump. However, call the APEP Main Office for details regarding these types of projects.)
  • Only one incentive per individual pump will be paid in any one six-year period.

Examples of ineligible projects include:

  • Projects involving multiple pumps, at different locations or on different meters.
  • Projects involving a change in horsepower (either a decrease or increase) – this does not necessarily mean a change in nameplate horsepower.
  • Retrofit or replacement of an electric motor only or installation of a variable frequency drive.
  • Retrofits required in response to the need to change the operating condition or use of the pump e.g., changing a well pump from low pressure flood irrigation to high pressure drip irrigation.
  • Construction or finishing of a new water well, including installation of a new or retrofitted pump.
  • Pump impeller adjustments only.
  • Well rehabilitation only, including chemical treatment, cleaning, swaging, or patching.
  • Projects intended only to reduce total dynamic head.
  • Pump disassembly, inspection, and cleaning only (no machine work).
  • Projects involving retrofit or repair of the tube, shaft, and/or column only.
  • Bearing or spider replacement only.

Projects involving the consolidation of a directly connected well/booster combination into a single pressurized well are eligible projects and would be considered as a single application. However, pre-project pump tests for both the well and the booster when running together need to be submitted. Absent supplemental information*, the discharge pressure of the post-project pump test should be within +/- 10% of the discharge pressure of the pre-test of the booster pump. (For example, if the pre-test shows 30 psi discharge pressure for the booster pump, the post-project pump test ideally would be performed with 27 – 33 psi discharge pressure.) In addition, for purposes of the incentive calculation: 1) the change in the total of the two pumps’ kWh/AF versus the kWh/AF of the single pressurized well will be the basis for any kWh savings, 2) the total of the two pumps’ nameplate horsepower will be the basis for any kW demand savings.

*  Some examples of “supplemental information” would be a) that water filters were in poor condition at the time of the pre-test and were subsequently replaced at the time of retrofit, thus altering the required discharge pressure, b) throttling valves were removed at the time of retrofit, thus altering the required discharge pressure, c) water tables have fallen dramatically since the pre-test, d) different irrigation sets were running during the post-test, or e) increased flow from the retrofitted pump resulted in higher pressure in the irrigation system.

If your project is ineligible for APEP, please note that PG&E has many other energy efficiency programs including the Savings By Design program for new construction projects and the Customized program for installation of energy efficient equipment or systems in existing facilities. Go on line to www.pge.com or call your PG&E account representative for more information.
