"We are very pleased with the results and particularly happy with the can-do attitudes of everyone for engineering and installing the air compressor system. They helped immensely in making the project goals achievable, as well as improving our plant in a cost-effective manner. Our plant and the community are better off as a result of the efforts."

Large Commercial & Industrial Program
Cash incentives that save your business money.
Entergy Arkansas offers a range of support specifically tailored to make your facilities more energy-efficient and help you save money.
Saving energy means saving money. That's why Entergy Arkansas'
Large Commercial & Industrial Program helps you make your business more energy-efficient. If you have any of the problems below, this program is for you.
High energy bills.
Limited control of lighting and HVAC.
Inadequate HVAC/chiller performance.
Solar heat gain from your facilities' windows.
Air compressors with significant air leaks.
Excessive or inefficient energy use in an industrial process.
Entergy offers cash incentives when you complete certain projects that make your business more energy-efficient. Additional benefits include an improved cash flow from significant, long-term electricity savings, as well as an improved "green" image of your business. Entergy will also help you develop an energy savings plan tailored to your buildings, and will even build energy efficiencies and savings into your work process. That way, you can focus less on energy costs and more on profitable gains.
This example illustrates a possible
scenario that might exist at a reasonably large industrial facility. Simulated existing conditions and sample proposed retrofits are
listed with example calculations of energy savings, incentives, and
simple payback. The data
given below is not necessarily indicative of what you may see at your
site, but can be reviewed to understand how the program will operate and
the potential value of a "Custom" project at your facility.
(3) 200 HP air compressors with inefficient throttling control, minimal air storage, and independent staging controls for each compressor based on system pressure
Replace the oldest compressor with a new 250 HP variable speed air compressor. Add system air storage and provide a system controller to stage/trim the air compressors based on system pressure
(3) 50 HP constant speed motors with on/off control that could be controlled at variable speed while maintaining process integrity
Provide (3) variable speed controllers for the motors and verify induction duty capability or place low-speed limitations according to motor manufacturer's specifications
(300) 400 watt metal halide fixtures
Replace metal halides with (300) 4-lamp T5HO fixtures and add advanced occupancy controls in appropriate areas
The approximate annual savings would be 736,435 kWh, resulting in $44,186 in annual utility savings. The cost of this project is $191,143, with an incentive of $132,558. If the facility was to make these upgrades, the net cost to the customer would be $58,585 (incentives cover 69% of project cost), yielding an approximate 1.3 year payback.
