Siemens has won an order to supply its HL gas turbine technology to re-power Cooperative Energy’s RD Morrow Sr Generating Station in Purvis, Mississippi, US.
The natural gas-fuelled combined cycle power plant with an installed capacity of around 550MW will use the HL gas turbine technology to re-power its existing coal-powered steam turbines.
For Siemens, this is the third order for its new HL-class gas turbine. Currently, two power plants using the HL-class gas turbine technology are under construction – one in North Carolina, and the other in Lincolnshire, UK.
Cooperative Energy will re-power one its current coal-fired generation units with a Siemens SGT6-9000HL gas turbine.
Under the order, Siemens will also have to provide an SGen6-3000W generator and the SPPA-T3000 control system.
Cooperative Energy’s member cooperatives serve around 430,000 homes and businesses in the state.
Siemens has also secured a long-term service agreement under which it will provide support to ensure optimal operating efficiency of the gas turbine and generator during the project lifecycle.
The contract includes service for parts, repairs, field services and programme management. It also covers offerings from Siemens’ Omnivise Digital Services portfolio, including remote monitoring and diagnostics.
Siemens country division lead for US power and gas John Gibson said: “Building on our well-established foundation with Cooperative Energy’s Batesville Generating Station, we are pleased to again partner with them on the re-powering of their RD Morrow Sr facility.
“The rigorous development of Siemens’ HL-class combines the world-class pedigree of our H-class with cutting-edge advancements. This technology is ideally suited to supply reliable, affordable, and low-carbon power across the state of Mississippi.”
Cooperative Energy senior vice-president and chief operating officer Nathan Brown said: “The Cooperative Energy consultants and staff went through a rigorous evaluation of the various combustion turbine technologies available and selected the Siemens HL-class gas turbine as the best overall technology for the Morrow Repower Project.
“Utilising the Siemens technology, we believe the resulting combined cycle unit at Plant Morrow will provide low-cost, reliable and low-emission energy for our members for many years to come.”
Earlier this month, Siemens signed a 15-year service agreement with Qatar Power Company (QPOWER) to maintain the 1,025MW Ras Laffan B combined-cycle power plant.
