The global data center generator market size was valued at USD 2.03 billion in 2021. It is expected to reach USD 3.23 billion by 2030, growing at a CAGR of 5.4% during the forecast period (2022–2030).
Data centers are mission-critical infrastructures that manage and process a large volume of data across multiple industries; as a result, data centers contribute significantly to the global economy. For data center facilities, however, reliable power backup to prevent data loss during power outages is of utmost importance. Generators offer a safe and cost-effective way to provide backup power for data centers and prevent the downtimes caused by restarting the entire system. Generators do not require an external power source to operate and can meet a data center's massive electrical power requirements have been the driving force behind the market's expansion.
Manufacturers of data center generators market are focused on equipping their products with technologically advanced features to meet the diverse needs of data center facilities. In addition, companies such as Cummins, Inc., and Himoinsa have added remote monitoring capabilities to generator sets. Thus, the data center operator can remotely observe the load levels, power system status, and alternator data and remotely control the alternator. These characteristics result in lower maintenance costs and increased operational efficiencies for the data center facilities. The market value chain for data center generators includes raw material suppliers, component suppliers, manufacturers, distributors, and end-users. Iron, steel, aluminum, plastic, semiconductor components, and insulating materials are the primary raw materials used in the production of generators. Some raw materials are supplied directly to generator manufacturers to develop the necessary components.
Additionally, raw materials are supplied to component manufacturers, who perform primary processing and distribute the components to generator manufacturers following their specifications. To meet the demand of generator manufacturers, vast quantities of raw materials are sourced from numerous sources. Demand for advanced generators with auto-start and stop systems is rising in data centers. A typical UPS can power data center servers for minutes. It gives data center operators time to start the generators after an outage. Thus, data centers need UPS to ensure uninterrupted power.
A data center is made up of networked computers and storage applications that are used to store, process, and distribute mission-critical data. As organizations expand and automate the management of their business data, several data centers are being established in various regions of the globe. However, effective power management is a significant obstacle for data center operators. Data centers use substantial electricity to power their computers, servers, and networking equipment. They also provide electricity to power the cooling equipment. Data centers must maintain temperatures of approximately 20 degrees Celsius. Not only can power outages disrupt the operation of the entire data center facility, but they can also affect the performance of the cooling equipment. Therefore, data centers rely heavily on generators to provide backup power during power outages. As a result, demand for data center generators is increasing, driving market expansion.
Several businesses are adopting cloud computing to improve their business operations' scalability, efficiency, and adaptability while simultaneously reducing their operational expenses. As more enterprises adopt cloud computing and rely on web hosting, colocation, and cloud services to run their operations, mega data centers are being constructed worldwide. While cloud computing involves managing large amounts of data, it also requires substantial computational power. The uninterrupted power supply is of the utmost importance if mega data centers continue to provide the necessary computational power during power outages. Thus, data center operators are aggressively investing in data center generators market to ensure an efficient and uninterrupted power supply for their data centers.
As data center power densities rise, backup power supply systems become increasingly important. Generators are powered by fuel and do not require an existing or stored power source to function. Consequently, they can serve as an efficient secondary power source in the event of a loss of primary power and power all of the data center's systems, such as computers, servers, networking equipment, and cooling systems. Thus, generators can guarantee a continuous power supply for data centers so long as they have fuel. However, conventional generator systems suffer from reliability and performance problems. Conventional generators sometimes fail to start or provide sufficient power due to issues with their subsystems. While their runtime was susceptible to low fuel levels, they frequently failed under unexpectedly high-power loads. However, advancements in generator systems, such as standby generator systems operating on diesel, natural gas, liquid petroleum, and gasoline, among other fuels, have resulted in the introduction of energy-efficient generator systems for data centers and are anticipated to create growth opportunities for the data center generator market over the forecast period.
Natural gas or diesel-powered standby generator systems are the most prevalent. A generator system typically comprises an emergency generator, an automatic transfer switch (ATS), and a management system. The figure above illustrates the output distribution. The ATS is supplied by two power sources, the utility, and the standby generator, with the utility being the preferred power source. In a power outage, the ATS automatically switches to the backup generator to ensure that the data center continues to receive uninterrupted power.
The fuel-powered generators used in data center facilities emit nitrous oxide, carbon dioxide, particulate matter, and other hazardous exhausts into the atmosphere. Therefore, data centers must comply with various environmental sustainability regulations when installing such generators. In addition, ample space and sizeable on-site fuel tanks are necessary for establishing the generators. In addition, a dedicated UPS is required for the generators to operate correctly. Due to the factors above, data center operators are evaluating alternative technologies to fuel-powered generators.
In addition, the integration of battery technologies such as fuel cells and Li-ion batteries has resulted in the emergence of fuel cell power systems, which is anticipated to impede market growth. Clean, scalable, and dependable fuel cells provide a means for data centers to satisfy their energy needs and environmental sustainability objectives. Depending on the fuel source, fuel cells offer low to zero emissions, thereby mitigating data centers' environmental and climate impacts. In addition, fuel cell systems can heat excellent data center equipment to maintain proper climate conditions, maximize server performance, and improve overall efficiency. Even though fuel cell power systems eliminate the need for large backup generators and reduce data center emissions, these systems have several drawbacks. Fuel cell power systems are more expensive per kilowatt-hour (kWh) than generators.
Moreover, fuel cell systems are only economically viable with government grants. In addition, fuel cell power systems have complex designs and require a constant power load. This factor continues to drive demand for power generators that are simple to install and have fewer complications than fuel cell systems.
In addition to data and productivity losses, power outages in data center facilities can incur high costs. There is a growing demand for dependable generators in data center facilities for efficient system backup due to the escalating frequency and severity of natural disasters and extreme weather events worldwide. Diesel, natural gas, liquid petroleum, and gasoline are used to operate generators. In the market for generators used in data centers, natural gas generators present the most significant expansion opportunities. These generators offer high efficiency and dependability, reduced gaseous emissions, and a chance for data center facilities to monetize unused power generators.
Furthermore, natural gas generators adhere to stringent government regulations regarding the greenhouse gas emissions of data centers. In addition, natural gas generators deliver superior efficiency and output power performance. In developed regions, the high dependability of the natural gas grid eliminates the risk of limited run times and refueling associated with other generator types. Natural gas generators can reduce the emissions of a data center. Natural gas-powered generators can reduce NOx emissions by 80 to 90 percent and CO2 emissions by up to 25 percent compared to diesel-powered generators. In addition, the relatively high prices of diesel and gasoline-powered generators and changing government policies and regulations are expected to spur demand for natural gas generator systems.

Based on tier standards, the global data center generator market is classified into Tier 1, Tier 2, Tier 3, and Tier 4.
Tier 1 is considered the lowest standard in data center infrastructure within the data center generator market. It is also recognized to be basic and inexpensive. Tier 1 data centers are normally designed with a single, non-redundant power source; that is to mean, they rely on a single path for power and cooling. This type of infrastructure would be applicable to small businesses or organizations that do not process very vital data and can therefore afford to lose some minutes or hours of uptime. For generators, most Tier 1 data centers would use standard generators. These provide power during an outage but lack many of the redundancy and reliability features in higher-tier deployments. These generators are crucial in cases where loss of power would result in loss of operation, but they do not provide the same level of operational continuity and fault tolerance as those used by higher-level data centers.
Tier 2 data centers are represented as having a higher reliability compared to Tier 1; however, they are not as robust as Tier 3 or Tier 4 facilities. Tier 2 data centers typically have redundancy in power and cooling but may not have multiple paths for power and cooling, which does impact overall uptime. Tier 2 data center generators must provide backup power reliably to run the operations of the center when outages occur; generally, however, the systems are designed with lower redundancy and less fault tolerance. In Tier 2 data centers, demand for generators will be driven by the need for better power reliability and cost efficiency while at the same time balancing operational resilience with investment considerations. These generators are critical for the continuity of service and reduction in possible downtown; however, the infrastructure is much less demanding compared to the higher data center tiers.
Tier 3 comprises data centers that are designed with a focus on minimizing downtown and enhancing reliability while offering balanced methodology between cost and redundancy. Tier 3 data center have the feature that they can run continuously while planned maintenance is going on, by duplicating important components and systems. Tier 3 data center design involves multiple independently maintainable power and cooling paths. No single component failure is capable of disrupting operations. Such a system will feature redundant generators, UPS systems, and cooling units; all this work together to deliver continuous operation and system resilience under any single component failure. Tier 3 therefore covers those enterprises that have strong infrastructure needs but not at the extensive cost associated with the highest tier of data center standards.
Tier 4 generators spell out the highest possible reliability and performance standards for any Data Center Generator Market. The added layer of redundancy and fault tolerance in Tier 4 generators provides maximum tolerance to continue operation without loss of power in the event of failure of more than one component. They have multiple power sources, large backup systems, and thorough maintenance procedures to ensure a 99.995% uptime rating. This tier is necessary for data centers requiring the highest level of reliability, which includes a mission-critical application and high-availability environments. Growing demand for robust and resilient data infrastructures to serve increasing digital and cloud computing needs, where any type of outage has an operational and financial impact, will encourage market demand for Tier 4 generators.
Covid-19 had some profound adverse impacts on the global advanced ceramics market.
COVID-19 spread across the world from China, making the whole world stand still and to a complete lockdown situation. Covid-19 is an infectious disease that was caused by a newly discovered coronavirus. During the time, the fatality rate among the population above 40 was also high globally. The disease causes severe illness for people suffering from medical conditions like diabetes, cardiovascular disease, chronic respiratory disease, etc.
Considering the situation during that time, it was declared a pandemic which led to numerous countries, including the major economies like China, the United States, India, and others, implementing lockdowns which adversely affected the global economy.
In the first two quarters of 2020, the economic and industrial operations temporarily halted. Almost every manufacturing unit where advanced ceramics is used, such as electrical and electronics, transportation, industrial, chemical, and other End-user Industries (except medical), reduced their manufacturing capacities due to the lack of workers. The lockdown implemented put a halt to global supply chains. This resulted in repercussions in terms of both production and demand for advanced ceramics.
With time the lockdowns were uplifted, and relaxation was made to the public. Gradually, the economy picked up the pace and started its operations, bringing the demand in the global advanced ceramics market and increasing among various industries. As the situation improved during the initial months of 2021, the economies also strengthened their fiscal policies and initiated their development process; the end-user industries began their activities, bringing the overall ceramics market back on track.
