Media Advisory:
Transport of CMP Autotransformer from Searsport to Windsor Scheduled to Begin on Wednesday

Who and what:
Contractors for Central Maine Power Company (CMP) will transport a 286-ton electrical transformer (15’H x 13’ W x 38’ L) over the road from Searsport to the Company’s new substation in Windsor as part of the Maine Power Reliability Program (MPRP).


Where and when:
The autotransformer was offloaded from the ship at the Mack Point Marine Terminal in Searsport on Monday. It is scheduled leave the terminal early Wednesday morning on a 16-axle tractor-trailer rig with a State Police escort. The total gross weight of the truck and transformer assembly is 426 tons (more than 852,000 pounds).


Autotransformer delivery schedule:
May 15: Depart Searsport at 5 a.m. The truck will travel south on Route 1 to 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 through Albion and China to South China, south on Route 32 to Windsor, then east on Maxcy’s Mills Road and across Coopers Mills Road to the new substation. The trip could take up to two days to complete.


About the Maine Power Reliability Program and the new substation in Windsor:
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 autotransformer for the new substation in Windsor is among the largest units in the Central Maine Power system. Transformers are used to raise or lower voltage on electrical systems. They will step down transmission line voltage from 345,000 volts to 115,000 volts to supply the electrical grid for communities across large areas of central and southern Maine.


CMP broke ground on the new substation in Windsor in August of 2011 and expects to complete construction in 2014. Eight transmission lines will interconnect there, and the facility will provide much of the power to the northern and eastern parts of CMP’s service area.
