The Challenge
Central Valley Foods required massive amounts of electricity and steam for processing operations. Separate generation of power and heat was inefficient and costly, with energy representing 25% of operating costs.
The Solution
Promise Energy installed a natural gas combined heat and power system that generates electricity while capturing waste heat for process steam. The system operates at 78% total efficiency.
System Specifications
- 1.2MW natural gas reciprocating engine
- Heat recovery steam generator
- Absorption chiller for refrigeration
- Advanced emissions controls
- Remote monitoring system
The Results
Reduced total energy costs by 42%
Eliminated need for backup boilers
Improved power quality and reliability
Met air quality requirements
Qualified for SGIP incentives
