Balancing plants with future-proof engines
Fast start-up times, superior efficiency, even at partial and low loads, and reliable and flexible operation make Everllence engines a highly valuable asset in the energy system. The high power density of our engines enables compact plant designs and optimized investment. And, of course, they comply with current emission regulations. But what about the future? Our future-proof engines can be converted to future fuels, preparing you for the transition to carbon-neutral fuels.
Medium-speed engines vs aeroderivative turbines
What if your balancing plant could deliver more than just power? Engines respond in minutes, maintain stable output when temperatures rise or altitude increases, and maintain high efficiency even when running at low load. Unlike aeroderivative turbines, they combine fast-start capability with consistent performance and the resilience to handle frequent starts and stops without added wear. The result is a technology that adapts to real-world grid demands and delivers reliable balancing power whenever it’s needed most. See how our engines compare to aeros — and why these differences matter for every grid, every day.
Find the balancing technology that really fits your grid
Balancing power can come from many sources: medium-speed engines, high-speed engines, aeroderivative turbines, and battery storage. Each technology offers different strengths in speed, flexibility, part-load behavior, and lifecycle performance. What matters is how well they adapt to real grid conditions – from sudden ramps to extreme temperatures and frequent cycling. That's where medium-speed engines often have an edge: stable performance across loads, resilience in demanding environments, and operating hours that turn flexibility into real value. Explore how these technologies compare and which strengths truly count for your business.
Key benefits
The Everllence future-proof engine portfolio
Our gas engines are built for tomorrow’s energy demands: H₂-ready today with up to 25% hydrogen in the gas mix – and upgradeable for 100% hydrogen operation through future retrofits. That makes them a reliable bridge to hydrogen-based power generation. Additionally, they can run on renewable alternatives like biogas or e-methane – cutting emissions without sacrificing performance.
Our dual-fuel engines offer outstanding fuel flexibility. They operate on both gaseous and liquid fuels – including advanced liquid biofuels – and can dynamically switch between them during operation. This gives you the freedom to adapt to shifting fuel availability, market conditions, and sustainability goals.
This compact engine delivers ultimate performance and top efficiency with low emissions – and is also available with two-stage turbocharging.
- Engine speed: 720/750 rpm
- Frequency: 60/50 Hz
- Up to 12,900 kWm
With best-in-class power output and low emissions, the 51/60G is setting new standards for gas engines. It is also available with two-stage turbocharging for superior performance.
- Engine speed: 500/514 rpm
- Frequency: 50/60 Hz
- Up to 20,700 kWm
This dual fuel engine converts diesel or natural gas efficiently, and can switch from one fuel to another without any fluctuations in speed or output. It's also possible to easily upgrade our 51/60 engine to dual fuel capability if necessary.
- Engine speed: 500/514 rpm
- Frequency: 50/60 Hz
- Up to 20,700 kWm
Energy transition scenario
Global electricity demand is on an unprecedented upwards trajectory.
By 2050, the power demand is projected to nearly double under the Stated Policies Scenario (STEPS) which reflects the trajectory of the energy system based on current policies and regulations that have already been implemented or officially announced. The Announced Pledges Scenario (APS) incorporates all climate-related pledges and targets that governments have publicly announced. The findings reveal that demand is set to more than double. This surge will be driven primarily by emerging markets, which are expected to account for around 70 % of the growth.
