Why gas engine solutions deserve a seat at the table — in Germany and beyond.

Global energy demand is accelerating, driven by data center growth, industrial electrification and the rising adoption of electric vehicles. But while consumption rises, grid capacity is struggling to keep up. Utilities are caught between challenging sustainability goals and real-world bottlenecks: aging infrastructure, permitting delays and renewable intermittency. The question isn’t if we need more flexible power. It’s how quickly can we bring it online?

Germany is the latest example. The country is experiencing capacity constraints as it moves away from fossil-fuel-based power sources and leans more heavily on renewables. To help maintain grid stability during this transition, the German government recently announced incentives for up to 20 gigawatts of new natural-gas-fired power by 2030.*

It’s a practical solution, but one that’s often approached with a centralized mindset: building capacity in a few large-scale facilities supported by extensive transmission infrastructure. Utilities historically have tended to think big: big plants, big projects, big costs. But the fastest path to grid resilience might just be smaller, smarter and closer to home.

Rethinking “Small”

Traditionally, utility-scale capacity has meant centralized power plants and working with a handful of major manufacturers. But as energy systems evolve, so does the definition of “scale.”

Large power plants are just one way to add gigawatts of capacity to the grid. Renewable energy installations and storage systems are another option. So is distributed generation with natural gas or biogas. In fact, multiple cost-effective gas-engine-based power systems can add up to big capacity — with shorter lead times and fewer infrastructure and maintenance requirements than a centralized plant.

As we consider our energy options for the future — whether that’s renewables, hydrogen, battery storage or something else — distributed gas generation is a proven way to bridge the gap and keep operations going.

4 Reasons Distributed Gas Generation Makes Sense Now

1. SPEED: A centralized, one-gigawatt power plant can take five to 10 years to plan, permit and build. A distributed generation system — made up of multiple-megawatt natural gas gensets — can be up and running in just weeks in some cases. It can also be standardized, replicated and installed where capacity is needed most, and it can help you avoid the long lead times and costly investments often associated with transmission and distribution systems. 
2. EFFICIENCY: Distributed generation is excellent for combined heat and power (CHP) applications, which are growing in popularity worldwide. Using natural gas gensets as part of a system to capture otherwise-wasted heat, your total efficiency can exceed 90% — supporting both cost savings and greenhouse gas reductions. That’s an improvement over combined-cycle turbines, which typically see maximum efficiency rates of 60%.
3. FLEXIBILITY: Big power plants can be slow to ramp up and operate best at full power. With distributed generation, you can bring installed gigawatts of power online in minutes — and turn it off just as quickly. That’s ideal for handling peak loads, providing backup power or filling in when wind and solar fall short. Plus, you can site distributed plants near end-users, reducing grid losses and congestion and increasing resiliency.
4. FUELS: Many natural gas gensets are already compatible with biogas, digester gas and hydrogen blends — which can help reduce lifecycle greenhouse gas emissions in the fuel value chain while increasing energy independence. That flexibility also lets you take advantage of locally available resources and future-proof your system as energy strategies evolve.

The Shift Is On

Germany’s energy strategy shift may be the most visible right now, but it’s not unique. Countries across Europe and North America face similar issues when it comes to infrastructure, demand and resiliency.

The need to stabilize the grid, avoid major price increases for consumers, and get ahead of future demand is very real. That’s where decentralized capacity offers another key advantage: It keeps additional infrastructure cost for distribution of electricity to a minimum. It’s a way to move faster and smarter.

Start Sooner. Scale Smarter. We Can Help.

It’s important to highlight that centralized power still has a significant role to play in increasing the grid’s capacity and that large power plants still have their place, especially for baseload generation. That said, the evolving energy landscape continues to require speed, flexibility and resilience — all things distributed natural and biogas generation can deliver.
