Estimate your business costs - Entergy Louisiana
Qualifying Entergy Louisiana business customers are now able to enroll in the Power Through offering.
With Power Through, you will have onsite back-up generation for a discounted monthly charge rather than independently purchasing and operating a full-scale generator solution. This program helps ensure participating customers keep the lights on and lets Entergy use this generation to serve demand in the local area. In addition, Entergy Louisiana will handle the installation and maintenance for you at no upfront cost.
The Louisiana Public Service Commission has already approved this program for eligible business customers.
If you have questions about the offering, please reach out to your Entergy Louisiana Customer Service Partner, or contact us.
