Power & Light Information

The Power & Light tariffs (PL-Small, PL-Medium, and PL-Large) are used by most commercial and industrial customers. The PL rates (tariffs) have an hours use of demand (HUD) structure, meaning not only energy consumption is used for billing, but also the rate at which the energy is used (demand).

The PL tariffs have "declining blocks", meaning as more energy is used, the cost per unit (kWh) goes down. Customers can get to lower cost energy by operating longer hours without increasing their rate of using the energy demand. One example of how to accomplish this is by going from a one shift to a two or three shift operation. Also, customers who have constant usage year-round will generally enjoy a lower unit cost than a customer with seasonal or sporadic usage.

Customers who operate during times when the demand on Georgia Power's generating system is highest will pay a premium for that usage. In high demand times, generally on summer weekday afternoons, Georgia Power must operate peaking generation, which is more expensive to operate than base load generation, such as coal or nuclear facilities. Thus, because large volume and constant users help Georgia Power operate its generating facilities more efficiently, they pay a lower unit cost for their electricity purchases.
