Capstone Turbine Receives Certification for Underwriters Laboratories (UL) Smart Inverter UL1741 Supplement A Interconnection Standard

VAN NUYS, Calif., April 04, 2019 (GLOBE NEWSWIRE) -- Capstone Turbine Corporation (www.capstoneturbine.com) (CPST), the world’s leading clean technology manufacturer of microturbine energy systems, today announces that its Model C65, C200, and C1000 systems are the first microturbines to be certified to the Underwriters Laboratories latest UL 1741 Interconnection Standard, Supplement SA.

UL1741 SA testing standard was created in response to the California Rule 21 and Hawaiian Electric Rule 14H. These rules were generated in response to the local increased presence of distributed generation and require interactive grid support functions.  UL then derived the testing standard by which all inverter-based energy technologies must comply.  Through smart inverter operation, the Capstone microturbine’s proprietary electronics ensure seamless integration in supporting the reliability and stability of the utility grid.  New distributed energy projects in California and Hawaii are required to comply with UL1741 SA.

“Utility grid interconnectivity is a critical technical capability supporting Capstone’s strategy for expanded deployment of our microturbine based distributed energy products. Capstone’s ability to comply with the various international and domestic standards using common hardware and software shows the versatility of our microturbine based technology,” stated Darren Jamison, President and Chief Executive Officer of Capstone. “This certification in California puts Capstone at the forefront of the market and helps to further our ability to partner with various microgrid project integrators,” added Mr. Jamison.

Capstone’s certification to the German BDEW and Italian CEI Medium Voltage standards in 2015 paved the way for developing the strategy, controls, and software behind the successful integration of UL1741 SA. With the eventual publication of grid support requirements by IEEE 1547, these grid reliability and stability functions will be required nationally.

“Capstone’s inverter technology enables us to adapt quickly to these certification changes and provide an all-inclusive power solution without the need to purchase extraneous grid interconnection equipment which would only add cost and reduced resiliency,” said Don Ayers, Product Engineering Director at Capstone. “The beauty of our Capstone proprietary technology and implementation is that they can be rolled into existing systems without any hardware changes. Backward compatibility is an important feature considering these standards are continually evolving,” concluded Mr. Ayers.
