The Contract Analyst Team looked at available data from regional utilities in order to determine the maximum technical demand response impact for irrigation pumps. The main finding was the irrigation pump DR coefficient of 0.8, which produces the total input power of a group of pumps when it is multiplied by the sum of  the nameplate horsepower ratings. The coefficienct includes the conversion from horsepower to kilowatts and the electrical efficiency of the pump motor under loading conditions found in the field. The DR coefficient was approved by the RTF at the May 21, 2019 meeting. Further, the RTF noted that different pump types and conditions experienced in the field meant that the DR coefficient would vary from pump to pump. However, it does allow power planners to calculate the accurate average impact on the grid of turning off a group of pumps.

Approve Demand Response Impact Estimate

Decision Details

Approve the recommended methodology for estimating maximum technical per unit potential of Irrigation Pumps as presented. In approving this, the RTF recognizes that additional factors will need to be considered to estimate achievable potential, including, but are not limited to:

  • the portion of systems automatically dispatched verses manually controlled
  • the coincidence between crop water usage patterns and peak loads
  • the relationship between event length and duration and participation rates.
