Representatives of Oklahoma Gas and Electric Co. and Public Service Co. of Oklahoma said the surcharge is needed to recover some of the infrastructure costs to send excess electricity safely from distributed generation back to the grid. The representatives said utilities need the new surcharge to prevent customers who can’t afford the installation costs of distributed generation from subsidizing customers who have the systems installed.

It's fairly complicated, selling DC current to an AC grid.
