Media Advisory:
Autotransformer Delivery to CMP Substation in Kennebunk Scheduled to Begin Monday

Traffic will be disrupted on Route 109; motorists urged to seek alternate route


Who and what:
Central Maine Power Company (CMP) is getting ready to take delivery of a 286-ton electrical transformer (15’H x 13’ W x 38’ L) for the Company’s new Maguire Road Substation in Kennebunk as part of the Maine Power Reliability Program (MPRP).


Where and when:
The autotransformer arrived in Maine by ship earlier this month and was transported by rail to a site near Maine Turnpike Exit 19 in Wells. On Monday, it is due to begin moving by truck (16-axle tractor-trailer rig with a State Police escort) to CMP’s Maguire Road Substation in Kennebunk. The total gross weight of the truck and transformer assembly is 426 tons (more than 852,000 pounds).


Delivery details:
On May 20, at approximately 12 noon, the tractor-trailer and its escorts will drive west on Route 109 and will proceed under the I-95 overpass using a “jack and slide” operation. This operation could take up to 12 hours to complete and is expected to disrupt traffic on Monday. Motorists are advised to seek an alternate route. Once past the I-95 overpass, the caravan will continue west on Route 109, north on Route 9A, and west on Maguire Road to the substation.


About the Maine Power Reliability Program:
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 Maguire Road Substation 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 southern Maine.

Note on photo ops and schedule:
The above schedules are subject to change without notice, so media should call Gail Rice at 629-7826 to verify the project’s status.
