PROJECT PROFILES

The staff at Process Energy Services has performed over 100 energy evaluations, training courses and energy program projects at various facilities. Profiles for several of our projects are listed below.

County of Hawaii Department of Water Supply

County of Hawaii – Process Energy Services performed energy evaluations for 250 pump systems with an annual energy budget of over seven million dollars. Project scope included hands-on pump efficiency testing, system analysis using DOE Pump Systems Assessment Tool (PSAT) software, developing tank release strategies, application of hydro-generation, development of energy conservation measures, and packaging the projects as a performance contract suitable for bidding. Process Energy Services also performed a micro hydro turbine evaluation for the County of Hawaii to evaluate the installation of turbines throughout the water distribution system. The project identified 12 sites with hydro units ranging from 10 kW to 100 kW.

City of Kelowna Wastewater Treatment Facility, Kelowna, British Columbia  

City of Kelowna, British Columbia, Canada – Process Energy Services performed a process optimization evaluation for the Kelowna Wastewater Treatment Facility that identified over 30% energy savings, 40% chemical savings and millions of dollars in capital cost avoidance savings that the facility had allocated for upcoming improvements. As part of the evaluation for the Kelowna Water System,  new pump optimization software was applied to over 30 water supply and booster pump systems. The program is designed to model pump performance and allow the city to evaluate the savings for variable speed drives, meet system pressure requirements and show how varying tank elevations affect the capacity and efficiency of the pump systems.

United Nations Industrial Development Organization, China  

Beijing, Nanjing and Shanghai China – Through funding provided by the United Nations Industrial Development Organization, Process Energy Services worked with other international experts to perform multiple workshops to train Chinese energy specialists to conduct plant assessments, and assisted with developing case studies on pump system efficiency. The project included the use of portable ultrasonic flow meters, power and pressure measurement instruments and pump system optimization software to identify energy saving opportunities at water, wastewater, and pharmaceutical companies.   

 U.S. DOE Waste Isolation Pilot Plant, Carlsbad, New Mexico 

U.S. DOE Waste Isolation Pilot Plant, Carlsbad, NM – Through the Federal Energy Management Program (FEMP) Industrial Facilities Initiative, Process Energy Services conducted a targeted energy and water use assessment for the water and wastewater systems at the U.S. Department of Energy Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. The WIPP facility is the world’s first underground repository licensed to permanently dispose of transuranic radioactive waste from nuclear weapon production and research. The site is located in southeast New Mexico and includes disposal rooms mined 2,150 feet underground in 2,000-foot thick salt formations. The evaluation identified projects to reduce existing water use by 83% and energy use by 60%. These projects are currently in the process of being implemented.

 U.S. DOE Best Practices Pump System Optimization Training  

Locations throughout the U.S. – Process Energy Services has performed training workshops for the U.S. Department of Energy’s Best Practices Program for several years. Members of our staff have been certified as DOE Qualified Pump System Instructors by demonstrating the ability to use the U.S. DOE Pump System Assessment Tool (PSAT) software to identify energy efficiency opportunities.

MWRA Energy Evaluations and Training, Boston, MA  

Massachusetts Water Resource Authority, Boston, MA – Process Energy Services staff managed a three-year energy services contract to perform energy evaluations at the MWRA water and wastewater facilities and pump stations. The evaluations performed included recommendations for water and wastewater pump system optimization, application of variable speed drives, electrical demand controls, and building system improvements. As part of this contract, an evaluation was performed for ten new 3500 hp pump systems installed at the Deer Island, North Main Pump Station. Each of the ten pumps are rated for 110 MGD for a combined capacity of over 700 MGD. All ten pumps are equipped with PWM variable speed drives. The evaluation included a review of daily operational data, system operation with facility staff, and pump performance data.  A series of energy efficiency training workshops was also provided to over 300 MWRA operators and maintenance staff.

Kauai Lagoons Golf Course, Kauai Hawaii

Kauai Energy Office, Kauai, Hawaii – As part of a U.S. DOE Grant, an energy audit was performed for the Kauai Lagoons Golf Resort Irrigation System using the Department of Energy’s Pump System Assessment Tool (PSAT) software. The improvements identified included replacing existing pumps with high efficiency units, installing demand controls and power factor correction capacitors, and installing variable speed drives. After the evaluation was completed, pump system training was conducted as part of the project.

Contract Operation Energy Studies, CT and MA

Process Energy Services conducted numerous water and wastewater facility energy evaluations for contract operators in Connecticut and Massachusetts. These projects included developing aeration system models to explore alternative process controls, optimizing pump system operation through variable speed drives and efficiency improvements, and identifying heating and ventilation system improvements to reduce energy costs.
