Dune AST has upgraded its facility with a natural gas fired Capstone microturbine power plant in Astrakhan, Russia. BPC Engineering, Capstone's Russian distributor, designed the project and commissioned the site recently.

Dune AST sought out an efficient and reliable energy system that required minimal maintenance and was environmentally friendly. Capstone microturbines were chosen for their ability to meet these needs while significantly reducing the company's energy costs.

The combined heat and power (CHP) plant consists of a Capstone C600 microturbine with a heat recovery unit and two hot water boilers. The plant operates in parallel with the local grid, generating about 60 percent of the factory's energy. The flexibility of the Capstone microturbines allows for irregular daily load profiles in order to maximize efficiency, even when operating at less than 50 percent total load.

Situated in an urban area, the power plant at Dune AST is subject to a strict set of environmental standards. Because of their clean exhaust, Capstone microturbines are fully compliant with these standards and do not exceed NOx levels higher than nine parts per million (ppm), which is 1/10 the emissions of traditional reciprocating engines. In addition, the thermal energy from the exhaust is captured to heat the factory space and provide hot water on-site. Deployed in this CHP configuration, the microturbine plant exceeds 80 percent system efficiency.

The cogeneration project was commissioned with the intent to install an absorption chiller...
