GE has announced the arrival of the first shipment of GE’s aeroderivative technology at Manildra Group’s cogeneration power plant at its world-class Shoalhaven Starches wheat gluten and starch site, in Bomaderry, NSW.
The remaining equipment will subsequently be delivered and deployed ahead of the site’s projections that the project will be operational by early 2023. GE will provide two LM2500+ aeroderivative gas turbines, two Heat Recovery Steam Generators (HRSG) with fresh air firing and associated Balance of Plant to deliver up to 54MW of electricity and 210 tons per hour (TPH) of steam on a continuous basis to Manildra Group’s Shoalhaven Starches site operations.

The new equipment will help transition Manildra Group’s energy supply from existing coal-fired boilers to natural gas-fueled operations, reducing CO2 emissions by up to 40 per cent.
Australian family-owned Manildra Group produces a range of Australian-grown and made food and industrial products, including wheat flours, bakery mixes, ethanol, starches, syrups, stockfeed and more. Shoalhaven Starches is the largest wheat starch and gluten plant of its kind in the world. The integrated sustainable manufacturing process at Shoalhaven Starches uses the entire wheat grain, relying on heat (from steam) production to power the site, day-in, day-out, 365 days a year.
The Shoalhaven Starches site requires continuous demand for large amounts of electricity and a significant volume of steam. Manildra Group turned to GE to deliver security of supply of both electricity and steam. Currently electricity is purchased from the national grid and steam delivered through existing gas and coal fired boilers. As part of the energy transition in Australia, Manildra Group needed to retire current boilers as well as become self-sufficient in supplying electricity without relying on the national grid. GE technology offered a turnkey solution for the complete cogeneration plant.
“We recognise that sustainable, stable, reliable, and affordable energy is critical to our manufacturing process, which is why we are delighted to employ GE’s advanced power and steam generating technology to provide cleaner and more reliable electricity and heat,” Manildra Group managing director John Honan said.
“This scale of investment in energy transition, generation and infrastructure cements our commitment to a more sustainable, and cleaner fuel powered site, and GE’s LM2500 turnkey power plant solutions will support us in continuing to produce the highest-quality Australian-grown and made products.”

GE Aeroderivative general manager Aman Joshi said, “Manildra’s transition from carbon intensive processes will help the state of New South Wales drive further progress in emissions reductions. With more than 150 million operating hours acquired over the last 45 years, GE’s aeroderivative turbines are taking flexibility and speed for power generation to a new level. We are confident that Manildra’s investment in our aeroderivative technology enables fast, economical and efficient power to help achieve its decarbonisation commitments.”
In addition to providing the technology for the cogeneration power plant, GE also signed an eight-year contractual service agreement.
