Retrocommissioning (RCx) for Commercial Buildings

Find out how you can reduce your energy bills and the cost of building operations with RCx.

Retrocommissioning (RCx) is a no-cost/low-cost program available to non-residential customers in the shared service areas of SoCalGas® and the Los Angeles Department of Water and Power (LADWP).

RCx Program Benefits

  • Cash incentives paying from $0.10 to $0.15 per kilowatt hour (kWh) and $1 per therm saved annually, or 50 percent of the project cost (excluding taxes and internal labor) whichever is less.
  • Reduced electricity and natural gas bills by up to 15 percent


All LADWP non-residential electric customers in good standing are eligible to participate in this program, as long as the building qualifies for one or more of the program’s 13 measures.

In addition, customers who receive service from both SoCalGas and LADWP are eligible to receive financial incentives on both natural gas and electric measures. The suggested (but not required) minimum building size is 50,000 square feet, and many measures benefit from a centralized building automation system.
