| Transmission Design Project |
| |
The Middleborough Gas & Electric Department contracted
with PLM to provide engineering and design services for
a new 3.75 mile 115kV overhead transmission circuit. The
project established a second 115kV delivery point to enhance
customer service and address rapidly growing load levels. |

| Municipal Substation & Distribution
Conversions |
|
The Town of Wolfboro Electric Department's distribution
system was operating entirely at 4.16kV and the Town was
relying on expensive on-site diesel generation to relieve
its fully loaded substation facilities during peak load
periods. PLM began with a System Planning Study to address
thermal overloads, low voltage, inadequate reactive support
and other unacceptable conditions. Based on the Study
recommendations, PLM prepared design and contract documents
for the construction of a new open bus 34.5kV to 12.5kV
substation. The project also included preparing design
and contract documents for the rebuilding and conversion
of a major portion of the 4.16kV distribution system to
12.47 kV operation. |

GIS Indoor 115kV Switchgear |
|
The Norwood Municipal Light Department needed to construct
a second 115 to 13.8 kV substation. After a comprehensive
system planning study and much community input, it was
decided that an indoor substation utilizing 115kV GIS
equipment was the design of choice. PLM assisted with
permitting at the Massachusetts Energy Facilities Siting
Board in order to obtain permission to construct a 2.2
mile underground extension of the 115 kV system. PLM prepared
design and contract documents for the 115 kV GIS switchgear
and all other major substation equipment, underground
ducts and manholes along busy US Route 1 and 115 kV underground
cable turnkey installation. |

Design-Build Substation |
|
This "design-build" project had
an extremely aggressive schedule. The PLM engineers coordinated
the design and schedule with the constructor, the upstream
utility, the project owner and the owner's independent
engineer. The substation was completed on time and within
budget. The project received a nationally recognized award
for "outstanding engineering and operations design." |
