Abstract
A comprehensive field data collection campaign is reported on in which operational data are being obtained from microturbine generators located in the South Coast Air Quality Management District (AQMD). The data obtained are archived in a SQL database, which provides the ability to look at various performance aspects as a function of many parameters interactively on the Internet. An overview of the program is provided along with details regarding the data collection and archiving strategies. To provide a framework relative to optimal operation of these systems in the region, economics associated with various operational schedules as a function of various rate structures in Southern California are provided. In addition to quantitative operational characteristics and performance results, some general end-user impressions of the technology and of the overall installation process are also documented. Details from three representative sites are presented.

Summary
Microturbine generators (MTGs) are being deployed worldwide for a number of applications. MTGs enable end users to generate their own power during times when power is in short supply, alleviating peak stress on the grid, reducing the likelihood of rolling blackouts that utilities may have to impose, and displacing emissions from the highest-emitting and least energy-efficient peaking units. MTGs are available from a number of manufacturers including Bowman, Capstone, Elliott, Ingersol Rand, and Turbec, and represent an option for on-site power generation technology (known generically as “distributed generation”). MTGs can, in principle, be installed relatively quickly and require little maintenance. In addition to providing electricity, a heat exchanger can be used with the MTG to provide heating or cooling, which increases overall system efficiency (“combined cooling, heating, and power—CCHP”). MTGs are capable of operating on a variety of liquid and gaseous fuels and are generally considered to be “low emissions” devices
