CMP to move 286 ton transformer from Searsport to Benton


Who and what: 

Central Maine Power Company (CMP) contractors will move a 286-ton electrical transformer (15’H x 13’ W x 38’ L) from the Mack Point Marine Cargo Terminal in Searsport to the Company’s new Albion Road Substation in Benton as part of the Maine Power Reliability Program (MPRP).
The transformer will make the 45-mile trip to Benton on a 16-axle tractor-trailer rig with a State Police escort. The transformer arrived in Searsport on July 27 following a three-month sea voyage from Taiwan.

Where and when: 

Monday, Aug 1, beginning at 6 a.m. from the Mack Point Marine Cargo Terminal in Searsport. The truck will travel south on Route 1 in Searsport into Belfast, north on Route 141 to Swanville, west on Route 131 to Waldo, west on Route 137 though Knox and Unity to Freedom, south on Route 202 to Albion, and west on Benton Road to Albion Road in Benton. The trip is expected to take longer than eight hours to complete. 

About the Maine Power Reliability Program and the Albion Road Substation: 

Central Maine Power Company’s MPRP is a $1.4 billion investment in Maine’s bulk power transmission system. The five-year project includes the construction of six new 345,000 volt substations, upgrades to more than 40 existing substations, and the installation or rebuilding of nearly 440 miles of transmission line in 75 communities from Eliot to Orrington.
The Albion Road Substation transformer is among the largest units in the Central Maine Power system. Transformers are used to raise or lower voltage on electrical systems. The Albion Road transformer will step down transmission line voltage from 345,000 volts to 115,000 volts to supply the electrical grid for communities in Franklin, Kennebec, Piscataquis, Somerset, and Waldo counties.


Note on photo ops and schedule: 

The transformer is presently in Searsport, and will be traveling throughout the day on Monday.  The above schedule is subject to change without notice, so media should call Gail Rice at 751-1081 to verify the project’s status.
