Public Hearing Continuation - Exelon Site Plan, 34 West & 9 Summer Streets
CONTINUATION DATE: Tuesday, July 26,2016 at 7:45 p.m.
LOCATION: Medway Town Half - Sanford Hall, 155 Village Street
At its meeting on July 12, 2016, the Planning and Economic Development Boord voted to continue
the public hearing on the application of Exe/on West Medway He and Exelon West Medway II, LLC of
Kennett Square, PA for major site plan approval of the proposed Exelon expansion project to Tuesday, July
26,2016 at 7:45 p.m. at Town Hall, 155 Vii/age Street. The focus topic for the Z6'h hearing will be to finalize
the site plan decision and vote.
The proposed project is for an expansion of the existing three-tu rbi ne, 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 lOO-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 sulfur 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 t he 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 facility services building, 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-d iked and covered
aqueous ammonia storage tank, advanced emissions control equipment, and a perimeter access road. Site
access will be controlled via a motorized security gate located off the relocated driveway from Summer Street.
The proposed facility will also include full acoustical enclosures for the gas tu rbines 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 SO' building to conta in flow
cont rol and metering equipment, and a 12' by 16' building to contain gas monitoring and analysis equipment.
If you have any final comments on this project, please send them to me by July 20'h. The revised
Exelon site plan dated June 17, 2016 has been posted to the Board's web page at:
