Helping EDF meet Europe’s energy goals
In response to Europe’s goals of lowering emissions and conserving natural gas, Électricité de France (EDF), one of the world’s largest utilities, is utilising GE Vernova’s 9HA turbine for their Bouchain plant.
A leader in H-class technology
Providing energy efficiency and fuel savings
The highly efficient, air-cooled 9HA gas turbine is an industry leader in the H-class space, delivering exceptionally low lifecycle costs per megawatt.
Cost-efficient conversion of fuel to electricity
The 9HA gas turbine is an industry leader in the H-class space, delivering exceptionally low lifecycle costs per megawatt. Over its lifecycle, total cost of ownership of the 9HA gas turbine is 5% lower than GE Vernova’s F-class—driven by lower capex, simplified configuration, decreased fuel cost from industry-leading efficiency, and extended maintenance intervals and reduced maintenance cost for H-class technology.
Industry-leading operational flexibility
GE Vernova’s H-class combined-cycle power plant has industry-leading flexibility and full combined-cycle plant load in less than 30 minutes, making it a great complement to intermittent renewable sources.
Lowest emissions in the industry
The 9HA’s DLN 2.6e combustion system offers a step change in performance, emissions, and fuel flexibility. The DLN 2.6e maintains many of the elements of GE Vernova’s DLN 2.6+ combustion system and introduces advanced premixing for reduced NOx emissions while enabling high plant efficiency. Its advanced premixer enables expanded fuel flexibility to operate on both “rich” and “lean” gaseous fuels, a 50% hydrogen (H2) capability with a technology pathway to 100%, a gas turbine turndown to more than 30% load, and an optional park mode at 7-15% load, further reducing customers’ operating costs.
Proven technology
Installing a gas turbine in your plant shouldn’t involve any unknowns. Across our HA fleet, each original turbine is put through several rigorous full-speed, full-load (FSFL) validation test at our Greenville, South Carolina facility. This $200 million investment allows us to push the units beyond real-world conditions—running the turbines at 110% of their rated speeds at load and replicating the harshest conditions. This type of extreme testing is possible because the gas turbine operates independently from the restriction of the power grid, enabling a much wider testing envelope than an on-grid facility.
Industry recognition
GE Vernova has been previously recognized by a 3rd party for setting two world records for powering the most efficient plant in an H-class combined-cycle (CC) application: 63.08% gross CC efficiency at Chubu Electric’s Nishi Nagoya power plant in Japan (7HA, 60Hz), and 62.22% net CC efficiency at EDF’s Bouchain power plant in France (9HA, 50Hz).
In 2021, Southern Power Generation’s 1.4 GW Track 4A power plant, a natural gas-fired power plant in southern Malaysia—equipped with the first commercial GE Vernova 9HA gas turbines—was recognized by POWER Magazine as their “2021 Power Plant of the Year” and by Diesel & Gas Turbine WORLDWIDE as “Power Plant of the World”, a meaningful model for balancing climate awareness, energy affordability, and reliability.
In addition, GE Vernova’s HA technology was adopted at China Huadian Corp’s Juliangcheng plant to help accelerate the retirement of existing coal-fired capacity and replace it with new, highly efficient combined-cycle gas turbines—an important role that earned POWER Magazine’s “ReinventionAward”.
Global experience
GE Vernova’s HA technology has been operating in our H-class fleet for ~7 years and has accumulated 1.9M operating hours (as of July 2023). GE Vernova’s HA portfolio is the world’s fastest growing fleet in its class with more than 145 gas turbines ordered by 50+ customers across 24 countries.
Simplified modular construction
GE Vernova’s H-class gas turbine packaging leverages a lean, modular, prefabricated approach engineered to achieve:
- Easier installation that reduces gas turbine installation schedule by up to 8 weeks
- Simplified unit maintenance with easy access to the gas turbine accessory systems
- Increased onsite safety
- Lower project risk
- More efficient inspection and maintenance
- Reduced gas turbine installation labor (about 13K man hours)
The gas turbine enclosure features modular architecture with valves, piping, and electrical systems packaged into stackable modules, which allows for simultaneous installations as well as reduced safety concerns and delays due to interfering tasks.
Cost-efficient imports to bridge the energy gap quickly
Reliable gas to power
A notable example from GE Vernova is the Porto de Sergipe power plant, an integrated gas-to-power project built on the coastal state of Sergipe in Brazil. The power plant is capable of generating 1.5 GW, or around 15% of the Northeast region’s power needs. It is the largest combined-cycle, gas-fired power plant in South America, enabling Brazil’s transition to lower-carbon energy.
The project required engagement with a wide range of stakeholders: thousands of local workers, community leaders, local businesses and government—with the 3,000 strong labor force, up to 60% of whom were locals. GE Vernova set up social programs and training centers where workers could learn on the job and obtain certificates that would serve them well beyond the project’s construction.
The project features three 7HA.02 gas turbines, together with a steam turbine and three heat recovery steam generators (HRSG). GE Vernova provided full engineering, procurement, and construction (EPC) of the gas power plant and grid construction, as well as associated grid interconnection systems (33 kilometers of overhead power lines and a 500kv substation) in addition to controls software and analytics and a 25-year Operations and Maintenance (O&M) service agreement. This integrated approach can be replicated in South Africa.
Hydrogen-ready gas turbines
Supporting South Africa's decarbonization journey with hydrogen
GE Vernova is the world leader in the application of fuels containing hydrogen in gas turbines. Over the last 50 years, our turbines have logged more than 8.5 million operating hours running on hydrogen with concentrations of up to ~100% (by volume).
Following a strategic cooperation agreement (SCA) signed among Egyptian Electricity Holding Company (EEHC), GE Vernova, Hassan Allam Construction, and PGESCO, a GE Vernova LM6000 aeroderivative gas turbine was safely and successfully run-on hydrogen-blended fuel for the first time in Africa.
