At its meeting on March 22, 2016, the Planning and Economic Development Board voted to continue
the public hearing on the application of Exelon West Medway llC and Exelon West Medway II, LlC of Kennett
Square, PA for major site plan approval of the proposed Exelon expansion project to Tuesday, April 26, 2016 at
7:30 p.m. in Sanford Hall at Medway Town Hall, 155 Village St reet. 4/13/16 NOTE - Due to the expected la rge
audience for this and another public hearing during the 4/26/16 meeting, the meeting location has been
changed to the School Committee Presentation Room at the Medway Middle School, 45 Holliston St reet.
The proposed project is for an expansion of the existing three-turbine, oil fired, 135 mega-watt West
Medway Station peak power generating facility located at 34 West and 9 Summer Streets. The planned
expansion entails the construction of two 100-megawatt (MW) simple-cycle, fast-starting, peaking electric
combustion turbine generators and associated equipment and appurtenances on approximately 13 acres of
the 94 acre property. Each of the two stacks will be 160' ta ll. The generators will run primarily on natural gas
using low sul fur diesel oil as a back-up.
The project will interconnect with Eversource via an approximately 1,200 linear foot overhead circuit
from a transformer to the Eversource switchyard on the western portion of the Property utilized and
controlled by Eversource through an easement agreement. The energy generated by the project will be
distributed by Eversource to the Southeast Massachusetts/Rhode Island ISO load zone to help meet energy
demand during peak times.
The project includes a control/administration and faci lity services build ing, a trailer-mounted
demineralizer system, an enclosed gas compressor station, a one-million gallon fuel oil tank, a 500,000 gallon
service water tank, a 450,000 gallon demineralized water storage tank, a 12,000 gallon fully-diked and covered
aqueous ammonia storage tank, advanced emiss ions cont rol equipment, and a perimeter access road. Access
to the site will be controlled via a motorized security gate located off the relocated main site access driveway

from Summer Street. The proposed facility will also in clude full acoustical enclosures for the gas turbines and
generators, a 55' high noise wall, and a full complement of acoustical controls. A 3,080 linear foot lateral
interconnection to the existing Algonquin Gas pipeline is also planned along with an associated 14' x 50'
building to contain flow control and metering equipment, and a 12' by 16' building to contain gas monitoring
and analysis equipment.
If you have not vet reviewed the project proposal and wish to provide comments, please do so by April
20tll so that we can share your comments with the Board and the applicant. Please contact me if you have any
questions. Thanks.
