Electric-standby truck refrigeration units (E/S TRUs) can plug in directly into the grid to power refrigerated trailers while parked at docks or loading bays rather than idling the engine to keep the contents cold.
CenterPoint Energy offers free assistance to customers interested in E/S TRUs or infrastructure. There are also customer incentives of up to $1,000 per bay available for eligible installations of infrastructure to support E/S TRUs. Contact us if you would like to:

Less wear and tear on the diesel engine while idling can also reduce maintenance costs by 15%.
Quieter & Safer Operations
Reduced noise from idling allows for greater operator awareness and reduced accidents.
Zero Site Emissions
E/S TRUs reduce greenhouse gas emissions from idling, contributing to a healthier, safer work environment for employees.
Cost Analysis
The chart below reflects the cost differences between a typical diesel TRU and an E/S TRU. As shown, electric-standby TRUs are significantly more cost-effective to own, potentially saving you over $17,000.
