Combined Cycle CHP Power Plant 12.5 MWe + 2.8 MW Chilled Water
This combined cycle CHP plant consists of one Dual Fuel Solar Turbine Mars 100 with 40 bar steam boiler, Siemens SST 060 Back Pressure Steam Turbine and one Double Acting LS Absorption Chiller with electrical, mechanical and control auxiliaries. Plant is maintained according to manufacturer’s instruction. Gas turbine engine was changed to Solar refurbished unit in June 2023 and it has accumulated only about 16000 hours since that. Both the gas turbine and the steam turbine were last overhauled by OEM service in mid-2025 and thus equipment is in good operational condition.
This combined cycle CHP (trigeneration) plant delivers 10 MWe of primary electrical output from a Solar Turbines Mars 100 dual-fuel gas turbine, with an additional 2.5 MWe from a Siemens SST 060 back-pressure steam turbine and 1.6 MWth of chilled water from two LS double-effect absorption chillers. The total combined electrical capacity is 12.5 MWe.
The turbine exhaust feeds a Descon water-tube HRSG with supplementary duct burner, producing up to 30 tons/h of superheated steam at 42 bar and 255°C. Steam drives the Siemens back-pressure turbine (year 2012), with exhaust steam at 7–9 bar feeding the absorption chillers for process cooling. The plant includes a fuel gas booster compression system, a nearly new GEA diesel fuel purifiers (year 2023), and a comprehensive inventory of original spare parts for all major components.
