Oklahoma Gas and Electric plans to charge large-load users more money for the power they use, targeting companies like data centers that use 75 megawatts or more a year."Think of your average big retailer that you might grocery shop at or buy your lawn supplies at. Those big-box stores consume about one megawatt of electricity per year," said Christi Woodworth, OG&E chief communications officer.

OG&E says the goal is to shield regular customers from footing the bill."There still will be some shared costs because we all share the grid, but those costs that are really designed to only serve that very large customer that consumes a lot of electricity, they'll be shouldering a heavier burden for their fair share or paying for anything that benefits them only," Woodworth said.

OG&E says the plan could put extra cash back into regular customers' wallets with a monthly charge that could reduce smaller customer bills by up to $30 million a year."That would go into a fund that OG&E would request the Oklahoma Corporation Commission approve the use of to be credited back to residential customer bills," Woodworth said.
