GE has announced that it has launched the 7HA.03 gas turbine, which will power Florida Power & Light (FPL) Company’s Dania Beach Clean Energy Center near Fort Lauderdale, Florida. GE describes the 7HA.03 as the world’s largest, most efficient, highest capacity 60Hz gas turbine, with industry-leading flexibility and the lowest cost of conversion for gas to electricity. GE said that the 7HA.03 offers an increase of 134MW than its 7HA.02 turbine, based on a 2x1 combined cycle plant, and an efficiency increase of 0.4 per cent compared to the 7HA.02, providing an estimated fuel saving of $0.9 million per year for US-based power plant operators.
The 7HA.03 offers several new design features. These include: a larger titanium Row 1 blade, enabling greater airflow and output; adoption of GE’s DLN 2.6e combustion system – the first of its kind on a GE 60Hz gas turbine – offers higher firing temperatures while maintaining emissions compliance. GE said that the turbine is able to turn down to 30 per cent load while still in emissions compliance, and is combined with an improved ramp rate of 75MW per minute, 15MW more than the 7HA.02, which enhances the ability of power plant operators to rapidly respond to market and grid conditions. GE claimed that the 7HA.03 in combined cycle mode can offer an efficiency of greater than 64 per cent.
Bill Yaeger, Executive Vice President of Engineering, Construction & Integrated Supply Chain at FPL said: “At FPL, we’re committed to delivering reliable energy, and as part of our longstanding programme of modernising our fleet of power generating facilities, we are replacing an aging power plant with a new, highly efficient energy centre using GE’s latest gas technology. By utilising the most advanced, most efficient gas turbine in GE’s 60Hz fleet, the FPL Dania Beach Clean Energy Center will allow FPL to continue delivering to customers the affordable energy they expect from us 24/7 to power their homes and businesses.”
