Reed & Reed was awarded the contract for the CMP Middle Street Substation project in late spring 2016 by AVANGRID. In January, 2017 we are in the midst of construction of this project to update and improve the electrical infrastructure serving a significant portion of downtown Lewiston, Maine.
The project includes the construction of the new Middle Street Substation which is comprised of two 115kV line terminals (one overhead, one underground), three 115kV power transformers, a two terminal 34.5kV bay for local transmission circuits and the control/powerhouse which contains 12kV switchgear distributing power to a large segment of the city. The substation foundations are complete, structural steel is up, the power transformers are set in place, and the work to install the remaining electrical equipment and conductors has begun. Construction of the substation is expected to wrap up in spring 2017 when the testing and commissioning of the new facility begins.
Once the new substation is commissioned and energized, Reed & Reed will continue our work by pulling approximately 57,000 feet of new 12kV power cable to re-feed nine (9) existing circuits. Along with crews from Central Maine Power Co., the closely coordinated task of cutting these circuits over from an existing substation will be performed in summer 2017. Once the circuits are energized, the project will conclude with the de-energization and decommissioning of the old Lewiston Steam indoor substation.
This major upgrade of the Lewiston substation infrastructure will increase reliability and improve CMP’s efficiency of operation in this key central Maine city. Reed & Reed is pleased to be the contractor.
