Combined Heat and Power

Selected Projects:
 

Demonstration of PureComfort System at Butler Hospital -

Carrier Department of Energy

Installed monitoring equipment to quantify the performance of this microturbine-based CHP system. The system includes an exhaust-fired chiller-heater that can provide chilled water to the central plant or provide hot water to meet space heating loads. Monitoring system measures the performance of the CHP equipment as well as the other equipment at the site in order to understand how effectively heat is being applied to meet the facility loads.

Web-based Monitoring System for EMMC CHP System -

Eastern Maine Medical Center Oak Ridge National Labs

Developed and operate a web-based monitoring system that extracts performance data from the facility control system and presents it on a web page. The Honeywell MC900 series control system logs the 15-minute data and it is exported to a FTP site. The web site processes the data every few hours and loads them into the web database. Quality control processes confirm that meaningful data are collected and any bad data values. Customized tables and graphs summarize the performance of the systems. Reports are available on a daily, weekly and monthly basis at this site.

Demonstration of CHP with Refrigeration Subcooling -

Exergy Partners Department of Energy City Public Service

Managed the design, installation, commissioning and monitoring of novel microturbine-based CHP system that used cooling from an absorption chiller to provide subcooling to a supermarket refrigeration system. Installed monitoring equipment to measure the performance of the CHP equipment as well as to determine if the supplied cooling successfully reduced refrigeration system energy use. Proved the validity of the refrigerant subcooling concept, though it was shown that the economics of the project were limited by Texas utility costs.

Field Demonstration of Microturbines at Floyd Bennett Field -

	New York State Energy Research and Developement Authority L&S Energy
	Developed and installed the monitoring system for a microturbine-based CHP system that uses waste heat to provide space heating and to drive an absorption cooling system. Also installed a PLC to control the CHP system and integrate it into the building. Worked with the project team to debug and commission the system.

DG/CHP Data Integrator System -

New York State Energy Research and Developement Authority

CDH is currently leading a team that developed and operates a web-based data system that houses monitored data and other information on NYSERDA’s portfolio of CHP demonstration sites. The website is at (http://chp.nyserda.org). The website, which includes detailed utility rate calculations, can use the hourly electric data available from each CHP site to calculate monthly cost savings due to the CHP system. The library of electric rate includes more than 200 tariffs for the New York utilities as well as rates for other utilities from around the US. The system allows the user to “move a CHP system” to other service territories in order to understand the impact of using different utility rates. As part of developing a DG/CHP web site for NYSERDA, we developed a Monitoring Protocol and Data Collection Standard (http://chp.nyserda.org/links/index.cfm) to help NYSERDA-funded sites meet the monitoring requirements. The monitoring protocol provides instruction and advice on the type and location of each monitored data point required to properly account for the energy flows in the DG/CHP system. The data collection standard provides guidelines for developing a monitoring plan for a site as well as details about sampling rate per data point, storage format and data delivery methods designed to work across a wide variety of monitoring hardware systems.

Develop Monitoring Specifications for NYSERDA CHP Performance Program (CHP3) -

	New York State Energy Research and Developement Authority
	CDH Energy worked with NYSERDA to develop M&V requirements for a performance-based incentive program for combined heat and power in Consolidated Edison territory. The M&V requirements define the detailed requirements to measure energy and demand impacts of CHP systems that will be the basis for the incentive payments.

Monitoring the Town of Perry Digesters -

	New York State Energy Research and Developement Authority Town of Perry, New York
	Installed monitoring system to measure the performance of anaerobic digesters at two farms the Town of Perry. Worked with digester provider (RCM Digesters) to measure appropriate parameters to quantify digester operation as well as the integration of thermal and electric outputs with facility loads.

Evaluating the Potential of Building CHP at a Large Resort -

	New York State Energy Research and Developement Authority Department of Energy
	We evaluated the technical and economic potential of a large CHP system in a large resort complex in Madison County. We developed detailed hourly models to predict thermal and electric loads and simulate performance of various CHP options. We explored and compared the impact of grid parallel and standalone CHP system operation.

Evaluation of a Microturbine-Desiccant System in an A&P Supermarket -

	Oak Ridge National Labs Nation Grid (as Keyspan Energy)" New York State Energy Research and Developement Authority
	We coordinated the installation of a microturbine integrated with a desiccant unit at an A&P supermarket in Hauppauge, NY. We measured the microturbine output as well as the heat recovered for space heating and desiccant dehumidification.

Field Evaluation of a Microturbine in a Supermarket Application -

	Oak Ridge National Labs
	We collected detailed performance data on a microturbine installed in a Kroger supermarket near Salt Lake City, Utah. We also examined baseline heating and cooling data to understand how the available waste heat could be used to meet these loads.
