PECO hopes to build an electric transmission substation on Fisher Road in Worcester Township, Montgomery County, the company said today.

The substation, on nine acres owned by Peco, will convert high voltage power from an existing transmission line into lower voltage power.

Peco, which must get approval from the Pennsylvania Public Utility Commission to build the substation, said it will alleviate congestion with power flows in the regional grid.

Peco expects to finish construction of the $50 million project by the summer of 2010.
