PHILADELPHIA -- Repair crews are making steady progress on restoring power to customers left without electricity after powerful thunderstorms moved across Pennsylvania.
PECO is reporting Friday evening that just over 11,000 customers remain without power in Philadelphia and its suburbs, almost half of them in Chester County.
PPL Electric Utilities says about 720 of its customers remain without power, scattered throughout central and eastern Pennsylvania. First Energy is reporting fewer than 900 customers without electricity.
At the storm's peak, nearly 171,000 utility customers had no power.
Thursday's stormy weather forced the postponement of several fireworks displays.
