“Peak shaving segment, by Operation, to hold third-largest market share from 2024 to 2029.”

The peak shaving segment holds third-largest market share in the global diesel power engine market by operation for several compelling reasons. Utilities and businesses increasingly rely on temporary power sources like diesel generators to meet surges in electricity demand during peak hours. This helps prevent blackouts, reduces strain on the main grid, and potentially lowers overall energy costs. While standby and prime power remain crucial for backup and continuous generation, peak shaving's growing role in grid management makes it a significant driver of diesel engine demand.

“0.5-1 MW, by power rating, to be the forth-largest market from 2024 to 2029.”

The 0.5-1 MW segment in your power rating segmentation likely holds the fourth-largest market share due to its well-rounded capabilities. This mid-range caters to diverse applications across industries, from providing reliable backup power for factories and commercial buildings to serving as the primary power source in remote locations with limited grid access. This versatility in addressing both backup and primary needs with moderate power output positions the 0.5-1 MW segment as a key player in the global diesel power engine market..

“Europe to be third-largest region in marine engines market.”

Europe holds the third-largest market share in the global diesel power engine market due to a confluence of factors. Firstly, its well-developed industrial sector relies heavily on reliable backup power, making diesel generators a crucial choice for factories and facilities. Secondly, while Europe prioritizes renewable energy, grid integration is still under development, and diesel engines play a vital role in peak shaving and grid stabilization during periods of low renewable energy generation. Finally, stringent emission regulations in Europe encourage advancements in cleaner burning diesel technologies, ensuring these engines remain a viable option for the foreseeable future.
