Boosting Power, Not Emissions

Waste heat recovery system to increase power without additional fuel, water

Posted on May 28, 2013

Berakas Power Company (BPC), Brunei’s national energy company, said it plans to install GE’s ORegen waste-heat recovery systems to increase the output and efficiency of four GE LM2500 aeroderivative gas turbines at the Berakas Power Station, located outside the capital city of Bandar Seri Begawan in the Sultanate of Brunei. The Brunei project is the first use of GE’s ORegen technology in the Asia-Pacific region.

The ORegen system will be connected to three of the LM2500 units, each of which generate up to 22 MW. The fourth LM2500 turbine and one waste heat recovery unit will be kept on standby.

GE is supplying its ORegen system with consortium partner Boustead International Heaters (BIH), which will provide its heat exchanger components as part of the package. The project is designed to help meet Brunei’s growing power requirements and has been made possible by the Sultanate’s “Green Brunei” initiative to promote energy efficiency and develop cleaner energy projects.

GE said its ORegen system utilizes a thermodynamic superheat cycle that recovers waste heat from gas turbines and converts it into 14 MW of extra net electricity without using fuel or water, or producing additional CO2 or NOx emissions.

The equipment for the Berakas project is scheduled to be delivered at the end of 2014 and commissioned in early 2015. The upgraded power plant is expected to start commercial operation in the first half of 2015. In addition to the equipment, GE also is providing site installation, training and a resident support engineer.
