< 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

< Back to all projects GENERADORA ELECTRICAL DEL NORTE LOCATION: Puerta Barrios, Guatemala SIZE & TECHNOLOGY: 5.8 MW Turbo Expander, Super Critical Propane, Cycle Evaporative Cooling DESIGN START: Fall 2012 IN SERVICE: Spring 2013 SCHEDULE: Construction Start Winter 2013, Construction Complete Summer 2013 FIRM ROLE: Engineering, Procurement Generadora Electrical Del Norte (Genor), a Guatemalan independent power producer, owned a 40 MW heavy fuel oil-fired reciprocating engine plant in Puerto Barrios, Guatemala. Recognizing the benefits of an improved plant heat rate, Genor under-took an analysis of ways to improve the output and efficiency of the Puerto Barrios facility. A number of options were analyzed to “combine cycle” the plant. The plant selected the Organic Rankine Cycle ORC-AT, as designed by Waldron. Waldron has an exclusive license agreement to design and construct the ORC-AT cycle. The cycle consists of a two-stage heat recovery system producing supercritical propane from exhaust waste heat. Energy in the propane is converted to shaft horsepower in a two-stage turbo expander coupled to a single generator via a common gearbox. Heat from exhausted propane is recuperated against propane prior to recycling to the superheater. Cooling for the cycle is via a bank of evaporative condensers. The plant will produce a net output of 4.0 MW for sale to the grid with the addition of no fuel input.
