The Washington, D.C., Public Service Commission first approved a net metering program in 1999 and has since updated and improved it. The system pays full retail value to residential and commercial customers who produce more energy than they use as long as their systems produce less than a total of 100 kilowatts. The payments are credited to the property owner’s next monthly bill. The credits may be carried forward indefinitely, but the commission will never pay the difference out in cash.
Systems that generate more than 100 kilowatts are credited at the generation rate, which is significantly lower than the retail rate.
Customers who participate in the program have to have a two-way meter that measures the flow of power in and out of the grid. The utility is authorized to install one of its own at the customer’s site.
The program caps out at 1 megawatt.
