DOWN GENERATING STATION LOCATION: Vineland, NJ DESIGN START/COMPLETION: Spring 2010 – Winter 2010 SIZE & TECHNOLOGY: 64 MW Trent 60 Gas Turbine / Dilution Air SCR / Natural Gas Compression / Utility Sub-Station IN-SERVICE: Spring 2012 FIRM ROLE: Engineering Vineland Municipal Electric Utility (VMEU) needed to expand the generating base within their service territory. A plan was developed to install 50 MW of capacity adjacent to the existing Howard Down generating station in downtown Vineland. Waldron was selected to be the engineer of record for the design of a new peaking facility. Waldron developed an equipment purchase set of specifications for a nominal 64 MW peaking gas turbine generator and SCR system. The bids were evaluated, and a recommendation was made to VMEU based on best value to select the Rolls Royce Trent 60 prime mover for the Howard Down Unit #11 . Waldron developed a detailed design package around the Trent 60 engine and supported VMEU in the selection and oversight of a general contractor to implement the design. The plant was placed in service on-time for the summer season, 2012.

< Back to all projects YALE UNIVERSITY ELECTRICAL WORK LOCATION: New Haven, CT PROJECT DATES: 2013 – 2016 FIRM ROLE: Designer, Commissioning Waldron has completed multiple projects for Yale University. Below are some of the electrical focused projects that have been completed. 1. Supplemental Generator Project a. Designed and installed 3 mobile generators to provide supplemental power to the Yale University Campus. The mobile generators operate in parallel with existing turbine generators and emergency generators. The three mobile generators run in parallel with each other and have load share capability. b. Controls of the generators are designed to operate the generator from three locations, local manually, chiller plant control room-automatically and the central power plant control room automatically. Controls for the new switchgear were connected into the DCS and existing synch panel for remote control. Raise/Lower voltage and frequency, synch check and other interlocks will be designed as needed. c. Arc Flash Study completed for all new equipment. d. Developed the Sequence of Operation for the generator control system. 2. New Vista Key Control Project a. Designed and commissioned the new Vista Switch Key Interlock Controls between four existing 15KV breakers. The Vista Switch Key Interlock Controls allow the associated 15 KV circuit breaker to be closed on a dead bus when the vista switch is open. This energizes the vista switch on the campus side of the switch and allows the utility to perform phase checks at the vista switch. The vista switch is not allowed to close if the key interlock switch is activated. All synchronizing remains across the 15KV breakers. b. Developed the Sequence of Operation for the Vista Switch Key Interlock control system.

< Back to all projects UNH PROCESS LANDFILL GAS PROJECT LOCATION: Durham, NH IN-SERVICE: 2009 SIZE & TECHNOLOGY: 7.9 MW Turbine/HRSG duct-Landfill gas/natural gas blend FIRM ROLE: Engineering and Design Waldron Engineering was contracted by EMCOR to design the installation of a landfill gas to energy system for the existing Siemens gas turbine and a HRSG duct-burner for the University of New Hampshire. Waldron was the Engineer of Record for the process landfill gas (PLG) project and assisted with work on the aspects of the landfill gas conditioning. The landfill gas is conditioned and blended with natural gas for the operation of the cogeneration facility. Waldron was responsible for providing a construction package that defined the work for the mechanical, civil, electrical and controls portions of the work. The construction specifications for the work were provided as part of the package. All the specs were coordinated with the existing UNH equipment and materials to maintain the consistency of the equipment in the plant. The UNH Cogeneration Plant consists of a 7.9-megawatt dual-fuel combustion generator train, including a HRSG (heat recovery steam generator) with a duct burner that produces 100,000 pounds of steam per hour and a 1,200-ton chilled water plant.

< Back to all projects MILFORD REGIONAL MEDICAL CENTER MICROGRID LOCATION: Milford, MA DESIGN START: January 2015 SIZE & TECHNOLOGY: 800 kW Reciprocating Engine IN-SERVICE: December 2015 FIRM ROLE: Engineering, Construction, Commissioning The installation of a new combined heat and power (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. 600 kW and 600 kWh Energy Storage System (ESS) operating in parallel with the existing CHP and utility. The ESS has the capability to black start the CHP and together can operate isolated from the Grid. With this new ESS addition, Milford Hospital established a highly resilient microgrid system with the option to add PV or other renewable generations. This project is endorsed by MA Dept of Energy Resource (DOER) Resilience Program. An economic benefit of ESS, is that it is able to do peak shaving to reduce the overall energy costs. Scope of work included: Construction Permitting Balance of Point—Detailed Design Review CAT Supplied Equipment Submittals Elevated Gas Permit Variance Construction Commissioning
