"IMPORTANT! As part of PG&E's response to customers who are highly impacted by the current drought PG&E will temporarily increase the incentive rate available for pump retrofits to $0.12/kWh from the current $0.09/kWh. The incentives are offered via the Advanced Pumping Efficiency Program (APEP) and are applicable to retrofit projects that involve retrofit or repair of the pump bowl and/or impeller only.  The increase is effective as of 5/15/2014.
To qualify for this promotional incentive rate, projects must meet the following requirement in addition to all other Advanced Pumping Efficiency Program guidelines:
The application for the retrofit incentive must be signed between 5/15/2014 and 12/31/2015. "

Pacific Gas and Electric Company (PG&E) is funding the Advanced Pumping Efficiency Program (APEP) through 2015 using Public Purpose Programs Funds under the auspices of the California Public Utilities Commission.  

Eligibility extends to all owners or users of a non-residential, PG&E electric or natural gas account that is primarily used for pumping water for the following: Production agriculture; landscape or turf irrigation; municipal purposes, including potable and tertiary-treated (reclaimed) water but excluding pumps used for industrial processes, raw sewage, or secondary-treated sewage.

Customers must pay the Public Purpose Programs Charge on their utility bill. Customers should call APEP for questions concerning program eligibility.
APEP has four program components:

1. Educational Seminars (free of charge)

2. Technical Assistance (free of charge but APEP does not provide site-specific engineering)

3. Subsidized Pump Efficiency Tests - APEP maintains a list of approved Participating Pump Test Companies.  Subsidized tests are only available through them.  The APEP subsidy may or may not pay for the entire cost of test.  The pump operator may have to provide some of these costs.  The pump test subsidy is now $200/test if the pump hasn't been tested in the last 4 year and $100/test if it hasn't been tested in the last 2 years. APEP will continue to provide only one subsidized test in any 2 year period (other restrictions may apply).

"IMPORTANT! Program eligibility and requirements have changed as of June 10, 2013.

1. To receive an incentive for a pump retrofit APEP requires pump efficiency tests both before and after the project.  These tests cannot be more than 3 years apart.

2. An application package for the incentive must be complete within 2 years after the after-project pump efficiency test.

3. Only one incentive will be provided for any one pump in a six-year period.

This program effort will provide for:

  • 2,700 subsidized pump efficiency tests per year. Click here to learn more about pump tests and how you could obtain one.
  • Cash incentives for 300 pump retrofit projects per year. Click here to learn more about eligibility and how you can apply for a retrofit Incentive
  • 10 educational seminars/year (refer to the events calendar to the right for notice of seminars coming to your area) - also, click here to view all of the APEP's educational materials.

PG&E offers many other energy efficiency programs in all markets, residential, commercial, industrial, and agricultural and for both retrofit and new-construction projects. Click here to learn more about these programs.

The Advanced Pumping Efficiency Program (APEP or the "Program") is a continuing effort by the Center for Irrigation Technology. It is intended as a multi-level program addressing the following important resource management problems in California:

  • Energy Conservation
  • Water Conservation
  • Water Quality
  • Air Quality

The twin goals of APEP are:

  • Get highly efficient hardware in the field, including pumping plants, irrigation systems, and water distribution systems.
  • Ensure that this hardware is managed correctly.

APEP has operated with funding from a variety of sources including the California Energy Commission, the California Public Utilities Commission, and the Federal Environmental Protection Agency. It works with agriculturalists and municipal and private water companies.

From 2001 through 2003 CIT implemented the Agricultural Peak Load Reduction Program on behalf of the California Energy Commission. This program provided the following to California during the “energy crisis”:

  • 9.3 megaWatts of reduced peak load (power use during the time period 12:00 noon through 6:00 PM in the summer months)
  • 88.6 gigaWatt-hours conserved annually
  • $7.4 million in distributed grants

From 2002 through 2012 CIT has operated APEP with funding from the CPUC and provided California water pumpers with:

  • 1750 pump retrofit / repair rebates
  • $6,900,000 in incentive rebates for those projects
  • 108,000,000 kilowatt-hours saved annually as a result of those projects
  • 373,000 therms saved annually as a result of those projects
  • 27,600 subsidized pump efficiency tests
  • $4,560,000 in pump test subsidies
  • 180 educational seminars


Diesel Pumping Efficiency Program

In addition to the APEP activities funded by PG&E, CIT also implemented a pilot program in the area of diesel-powered pumping plants on behalf of the Federal EPA and the Valley CAN group. This effort resulted in 69 pump efficiency tests, 11 pump retrofit projects, and preparation of a diesel pump testers kit including computer software to database and perform calculations regarding the test, instructions for assembling equipment necessary to measure fuel flows, and guidance on performance in interpreting the test results. The background thesis paper regarding this effort can be read here.

Although the main objective of the diesel-oriented program is improving air quality through reductions in emissions from the diesel-powered pumping plants, we also emphasize sound water management.
