(Richmond, IN)--When the Richmond Power and Light Board meets Monday night, it’s expected to pass a resolution for an economic development rider. That rider would result in lower energy costs for large, industrial customers. Here’s how it works. RP&L will receive a credit for qualifying customers from IMPA which will then be passed on to the customer. It would result in a 20% savings in the first year, and decreasing amounts for the next four years.
