WHITE PAPER
7HA.03
The Next Evolution of the Gas Turbine
GE Vernova’s 7HA.03 gas turbine has
industry-leading flexibility: full gas turbine
load in 10 minutes, full combined-cycle
plant load in <30 minutes, greater fuel
flexibility, and is an ideal complement
to intermittent renewable sources.
The International Energy Agency (IEA) projects total
electricity demand will rise by nearly 60% through 2040.
For the first time in history, more natural-gas fired power
generation capacity is forecast to be added over the next
decade than from any other fossil fuel source. In addition,
rapid growth in renewables is changing the electricity supply
landscape and how gas turbines are being called on to
generate power to the grid. The modern power grid needs
resources that can ramp up and down, swiftly, efficiently
and repeatedly. And, operational flexibility is critical for gas
turbines that complement renewable energy as it balances
electric system loads and helps maintain grid reliability.
GE Vernova’s HA gas turbines are the proven product solution
to support power producers and their power generation needs.
GE Vernova’s HA Gas Turbine Technology
GE Vernova’s heritage is unparalleled in the power
generation industry. We led the industry by beginning
H-Class technology development 28 years ago and GE
Vernova was the first to introduce the H System*. Today GE
Vernova’s H-Class—the HA introduced in 2014—combines
our experience from first-generation H-Class steam cooled
architecture with proven F-Class gas turbine technology.
Our design practices are based on learnings from our entire
gas turbine portfolio. In addition, over the past 70 years
we’ve leveraged material science innovations from our
history in aviation to gain increased performance at higher
firing temperatures.
Today, GE Vernova’s HA technology is the fastest growing
fleet of gas turbines in the world with orders from more
than 40 customers in 18 countries. The current fleet has
accumulated more than 415,000 fired hours of commercial
operation across 40 gas turbines, including 29 7HA’s.
Features/Benefits
On-going product evolution is essential to maintaining
commercial vitality for our customers. GE Vernova’s 7HA.03
gas turbine is an evolution of our HA platform, based on our
proven HA architecture that maintains design consistency
across all fleets:
• Proven 14-stage compressor design
•  Retains one set of inlet guide vanes (fully electrical) and
three sets of variable stator vanes (fully electrical) and a
continued proven use of a Titanium R1 blade row
•  12-can, dry low NOx combustor with axial fuel staging and
unibody construction
• Proven 4-stage gas turbine
•  And like its HA predecessors, comprehensive full-speed,
full-load testing on Test Stand 7 in Greenville, SC, delivering
durability improvements and performance upgrades
While retaining a common architecture, the 7HA.03 gas
turbine is a step forward in technology that offers power
producers 3 key benefits:
1. BETTER GAS TURBINE PERFORMANCE
•  Highest capacity 60 Hz gas turbine—a 430 megawatt
(MW) gas turbine and ratings in combined cycle
application of 640MWs (1x1) and 1,282 MWs (2x1)
•  134 MW’s more than the 7HA.02 (2x1 CC), equivalent to
powering 100,500 more homes
•  Unmatched efficiency available at >64% net combined
cycle, higher than any other competing technology today
(2x1 CC), 0.4 % more efficiency than the 7HA.02, saving
~$0.86M a year in the US.
•  The 7HA.03’s gas turbine rating and fuel efficiency
improvements offer customers the lowest $/kwh
conversion of gas to electricity.
•  Wet compression enables up to a 7% power increase
for customers, which is especially useful in hot or
tropical climates
