PROJECT SHEET

ATLANTIC CITY LANDFILL ENERGY

Egg Harbor Township, NJ

Waldron Engineering & Construction, Inc. was contracted by DCO Energy to develop a
design for the addition of landfill gas conditioning equipment for Atlantic City Landfill
Energy. The project was two phases; process design followed by the development of con-
struction drawings. The goal of the project was to install a chilling system to remove con-
densable gas from the landfill gas stream and provide for a future allowance for the addi-

tion of a siloxane removal system.

The process design phase modeled the performance of the existing system to determine
the base line performance. The model utilized the existing piping layout, performance
curves for the blowers, known characteristics of the land fill gas and site operational
measurements. Once calibrated to the baseline performance, the model was modified to
include the characteristics of the new chiller system. The construction drawings were de-
veloped to implement the project included: general arrangement drawings, system P&ID,
electric one-line, misc. equipment pad, piping drawing, wire list, control system and con-

struction specifications.

BRIGHAM AND WOMEN'S HOSPITAL

Boston, MA

Waldron Engineering & Construction, Inc. was contracted to do a study for Brigham and
Women’s Hospital (BWH) to evaluate the feasibility and economic value of installing a
Combined Heat and Power Plant (CHP) in theit new Brigham’s Building for the Future
(BBF). The primary purpose for the CHP is to provide operational cost savings to the
hospital and a level of resiliency to serve the energy needs of the facility. In addition to
studying various CHP technologies, including combustion turbine generator and recipro-

cating engine generators, Waldron appraised the value of supplying electrical and thermal
which is part of the Brigham and Women’s Hospital campus.

Upon identifying that a 4 MW reciprocating engine based CHP was the optimal size and
technology to serve the two buildings, Waldron executed the detailed design of the entire
central energy plant. The building is expected to be occupied in late spring 2016.

PROJECT SHEET

MILFORD REGIONAL MEDICAL CENTER

Milford, MA

The installation of a new CHP system at the Milford Regional Medical Center was executed as a fast
track project by Waldron. Milford was looking for cost savings and resiliency for their campus. The new
CHP system included a packaged 800 kW natural gas fired Caterpillar engine and waste heat recovery.
Heat from the jacket water system and the engine exhaust are utilized to produce 15 psig steam for the
hospital low pressure system. Energy from the engine lube oil system was recovered and utilized for the
domestic hot water system. The CHP system will provide operational cost savings and in the event of a
power outage, could supplement the emergency diesel engines to provide power to the hospital. The
project was completed in 10 months, from notice to proceed to utility acceptance testing.

The City’s preference is to replace the existing Waukesha Engine with 2 CAT engines.
What is the preferred CAT engine model?

Answer: We expect the consultant to meet with CAT representatives to go over suitable
CAT gas generators based on the design parameters determined by the consultant. Once
a suitable CAT model is determined it will be discussed with the City for final approval.

What is the future expansion plan for gas production and electrical consumption?

Answer: At this time we do not know how much to expect for an increase in digester gas
production. There could be slightly higher loadings to the digester with upgrades to the
primary sedimentation tanks (currently in design phase, upgrades are expected to be
complete in about 2-3 years) which may result in slightly higher gas production. As the
City population continues to grow, more solids will feed the digester resulting in an
increased gas production. However, the rate of growth is very slow. In summary we do
not expect much greater gas production than the system currently produces for the near
future unless a supplemental food source (more septic loads, food waste...) is brought in.

Please provide information on the existing plant control system (Delta V, etc.).

Answer. The gas generator will be controlled by a control panel mounted on or adjacent
to it. This was the arrangement when the Waukesha generator was operational. SCADA
is used to monitor the cogen system: check gas production, flow rates, check generator
production (Kw), check coolant temperature, review trending...

What are the evaluation parameters for the gas cleansing room, exhaust gas flare, gas
hold tank feed system?

Answer: The crux of this project is to replace the existing Waukesha generator with 2
new CAT generators each sized to meet the gas generation production rate, and the
replacement of associated components in need of replacement (heat exchangers, exhaust
system, controls...)._ However, we expect the consultant to conduct an overall evaluate
the other components of the cogen system. Equipment in the gas cleansing room, boiler
room... Should be evaluated to be certain it is sized correctly and also an estimate of the
useful remaining life. Any recommendations for changes should be noted in the
preliminary design report. If something is in need of immediate replacement it may be
added to the project depending on costs.

What level of assistance should the bidder provide during the bid phase?

Answer: The consultant being hired is just for the design and bidding phases of this
project. The City will send the project out to bid and will seek assistance from the
consultant to answer Contractor questions concerning the plans and specs. We will also
request the consultant to recommend the lowest qualified bidder.
