Customers are eligible to earn cash incentives based on the implementation of the measures identified in the analysis. The energy savings and the time it takes to implement the measures are factored in the calculation of the customer incentive.


This program is available to non-residential customers within the CenterPoint Energy Houston Electric service territory. Retro-Commissioning is offered to existing commercial buildings including manufacturing facilities, hospitals, educational campuses, and retail stores. To qualify, customers must install -- at their own expense -- specified low-cost measures to reduce operating and energy costs (i.e. Heating, Ventilation, and Air Conditioning [HVAC] temperature reset, outside air reduction, optimized HVAC start-up, adjust LED lighting schedules, etc.)

  • A technical energy analysis (comparable to an ASHRAE Level 2 audit) is performed on your facility at NO cost to Owner, by a qualified RCx agent (engineering consulting firm specializing in your market segment). A list of qualified RCx agents can be provided by the CenterPoint Energy Program Manager. 
  • Projects must be completed by approved project deadlines, typically within 2 years. 
  • Facilities should have a higher-than-average energy consumption. 
  • The optional Monitoring Based Commissioning (MBCx) track involves the use of hardware and software to commission buildings on a more frequent basis. MBCx includes the use of trending data to identify new energy savings opportunities and to investigate underperforming measures to improve persistence of savings.  
Terms and conditions apply.
