PORTSMOUTH, N.H., Dec. 19, 2018 (GLOBE NEWSWIRE) -- FlexEnergy Inc. today announced that it has commissioned a site for a leading manufacturer of animal feeds and fertilizers to farm and home markets in Puerto Rico.  The customer purchased two Flex Turbine® GT333S units as the central part of a Combined Heat and Power solution.  The two units provide 0.660 Megawatts of clean and reliable power for the customer’s primary manufacturing plant running on propane fuel. 

In this application, the Flex Turbines will operate in dual power mode in parallel with the local PREPA utility in normal operation.  When PREPA experiences an unplanned service interruption, the units perform a closed transition, disconnecting from the utility while staying connected to the site loads in grid isolated mode.  This configuration ensures priority loads are maintained and manufacturing operations can continue uninterrupted through a utility power outage. When utility power returns, the turbines perform a closed transition to parallel operation with the utility, continuing to support the site loads.

The Flex Turbines are integrated with a Heat Recovery Steam Generator (HRSG) and FlexEnergy exhaust diverters. The waste heat generated from the Flex Turbines is fed into the HRSG to produce steam, which is used in the manufacturing process. When steam is not required, the Flex exhaust diverters send the exhaust out the turbine exhaust stacks. The entire solution is controlled by a FlexEnergy Supervisory Control Master unit, which provides for remote monitoring and control.
