Typically, data centers with capacities of 50-400 MW opt for medium-speed engines, while smaller centers (20-100 MW) may still choose high-speed engines [1][7][8]. - **Market Trends**: The North American data center market shows a trend towards larger installations, with mainstream capacities ranging from 100-400 MW. Large orders dominate, reflecting a shift towards larger data center projects [2][10][11]. - **Price Increases**: In 2025, there was a significant price increase for power generation equipment, with some models rising by as much as 30%, primarily due to rising costs of small components in the supply chain affected by metal and material price fluctuations [1][14]. - **Supply Chain Dynamics**: In cases of shortages, North American customers may consider second and third-tier brands, but core certification requirements remain stringent to ensure stability and safety in data centers [1][15]. Additional Important Content - **Technical Differences**: There are significant differences between internal combustion engines and gas turbines in terms of system structure, operation, speed, and maintenance cycles. Medium-speed engines are preferred for larger power stations due to their lower overall costs and longer design life, which can exceed 30 years [3][6]. - **Core Components**: Key components of internal combustion engines include crankshafts, turbochargers, fuel injectors, and control system components, which significantly influence performance and manufacturing costs [6]. - **Hydrogen Technology**: Current developments in hydrogen blending technology allow for up to 25% hydrogen to be mixed with natural gas, although this reduces power output by 9-10%. Future exploration into new fuels like ammonia and methanol is ongoing, but economic viability remains a concern [18]. - **Market Delivery Projections**: In 2025, approximately 2.1 GW of medium-speed internal combustion power generation equipment was delivered in North America, with light gas turbines at about 3.196 GW.
