Regulators just approved a deal that would create America's biggest utility company

Regulators approved Exelon’s takeover of Pepco utility on Wednesday afternoon.

Pepco shares surged by as much as 27% in trading, after being halted earlier.

The merger, first announced nearly two years ago, would create America’s biggest utility company.

Here’s a chart showing the surge in Pepco shares, which have moved higher by a record amount according to Bloomberg:
