< 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

Waldron was selected as the EPC contractor to install a gas turbine based CHP plant in a stand alone building adjacent to the manufacturing plant. The prime mover selected was the 4.5 MW Centaur 50 gas turbine, manufactured by Solar Turbines. Heat is recovered in a Rentech supplemental fired boiler that produces up to a peak steam output of 60,000 lb/hr. Integral in the boiler is a SCR system to control NOx emissions to 2.5 ppm at the stack. The plant was named a Pace Setting Plant in the Combined Cycle Journal, second quarter 2009.

In developing the One Bryant Park building (a.k.a The Bank of America Tower), The Durst Organization made a commitment to achieving the lowest environmental footprint. The building, which is located one block off Times Square on Sixth Avenue, is a 50-story structure that is predominately leased by Bank of America. The building is designed to conserve energy wherever possible. The energy that is consumed is supplied by a gas turbine-based CHP facility located on the 7th floor podium. Waldron designed the complete plant around the Solar Mercury 50 gas turbine that exhausts into a fired HRSG. The HRSG is sized to serve the complete needs of the building. The building set a new standard in sustainable commercial construction by utilizing the least amount of energy possible, and the energy consumed is generated in the most efficient manner possible. It is the first LEED Platinum high-rise office tower in North America and ranks among the most environmentally advanced skyscrapers in the world.

< Back to all projects COLUMBIA UNIVERSITY LOCATION: New York, NY STUDY DATE: April 2011 TECHNOLOGY: 11 MW 80,000 lb/hr Solar Mars Gas Turbine FIRM ROLE: Feasibility Study and Detailed Design Columbia University retained Waldron Engineering & Construction, Inc. to study the opportunity for Combined Heat and Power (CHP) at its Morningside Campus. The CHP will include on-site electric generation and recovery of waste heat in the generation of electricity to heat and cool campus buildings. The single most important driver for the study, other than its economic feasibility, was to determine if CHP offers a cost effective and reliable means to significantly reduce the University’s GHG emissions thru the recovery of waste heat and reduction of fossil fuel burning, in indirect purchased electricity and onsite usage, to meet the Morningside Campus’s energy needs. The project team considered a wide range of CHP technologies and configurations to be sited at the existing steam & chiller plants below the Center for Engineering and Physical Science Research (CEPSR). The CHP technologies investigated included: combustion turbines, fuel cells, reciprocating engines, and steam turbines in configurations sized up to about 14.5 MW. Waldron was selected to execute the detailed design for the project.

For this project Waldron was tasked with doing a feasibility study on installing an energy storage system for their existing combined heat and power plant (CHP). The scope of services for this project included the following: 1. Develop a typical year 8760 model of the operation of the CHP and utility purchases as the base case model. 2. Develop three different cases of an economic analysis with the energy storage system in conjunction with the CHP to determine the energy saving from peak demand reduction, energy arbitrage and other operation efficiency optimization. 3. Define operational improvements associated with the installation of the energy storage system and the components required to achieve these improvements. Improvements will include: Resiliency improvements Bus stabilization benefits when operating in island mode. Load balancing when operating in parallel and not exporting. Black start capabilities (for existing CHP) 4. Identify the electrical equipment and control system needed to successfully comply with the incentives, achieve the economic benefit and operational benefits. 5. Develop a cost opinion that includes equipment, installation, engineering, commissioning, project administration, interconnect cost related to resilience equipment and other costs as may be required in the incentive program 6. Assist UMMS in the preparation of the application for an energy storage grant.

The basis for the study was an hourly utility model that was developed from utility load and cost information supplied by NSSC. The objective of the project was to determine the optimal-sized prime mover, evaluate the financial performance of the project, and develop a cost estimate to construct and commission the facility. Waldron also evaluated the utility modifications and interface changes required to operate the facility electrically as a Microgrid with thermal distribution loops. The recommended configuration is proceeding as a third party paid ESPC project.
