Data Center Generators Sets are a critical component of any data center. These units provide the power required to operate and cool the servers and network equipment.
The generators are typically located outside the building to ensure no interruption in service if there is an outage inside the facility.
These units must be able to provide enough power for all critical systems and any backup sources necessary to keep everything running smoothly in case of an emergency.
The Data Center Generator Set consists of several generators, including standby, prime, and diesel-powered models.
Standby generators are used when a utility power failure occurs or when there is a scheduled maintenance outage at the facility where they are installed. They automatically turn on when needed, providing electricity until utility power returns or until the maintenance schedule ends.
Prime generators are usually used for smaller facilities that do not require constant availability from their generator system but still need some level of protection from power outages due to weather conditions or other issues that affect local utilities like power lines or transformers blowing out during bad weather events such as hurricanes or tornadoes.
Data centers are the backbone of our digital world, and their availability is critical to the success of any business. That’s why we take great care in selecting and installing only the best backup generators for data centers.
Generator sets are rated by kVA (kilovolt amperes) — one kVA equals 1,000 watts. The number of kilovolts and amperes (kVA) needed will depend on the size of your data center and how many servers you have running at once. A generator set that provides 15kVA will typically power a facility with up to 20 racks of equipment while consuming 1/2-1 gallon per minute (GPM) fuel flow from its tank.
Here’s a list of some popular generator sets used in today’s data centers:
1. Caterpillar C7 Genset
This is the most popular data center generator set ever produced. It was introduced in the year 2005 and is still being used in data centers around the world. This unit has a 710-horsepower output, which can be boosted up to 1,200 horsepower. It weighs about 8,000 pounds and runs on diesel fuel. The Caterpillar C7 Genset can run for up to 12 hours without refueling or servicing its engine or cooling system.
2. GE GEnx Gas Turbine
The GE GEnx Gas Turbine is an advanced gas turbine power generation unit launched by General Electric in 2012. This unit has a variable speed compressor that allows it to provide constant power even when the load changes drastically from time to time. It also has a dual fuel capability that will enable it to run on natural gas or liquid petroleum gas (LPG), making it suitable for use in remote locations where no pipelines are available for natural gas supply. The GE GEnx Gas Turbine weighs about 7,500 pounds and can run for up to 17 hours without refueling.
3. Schneider
Schneider Electric’s most popular generators are the Merlin Gerin Power Pack series. These units are high-quality diesel generators designed for commercial use.
They have very low emissions and are easy to install and maintain. The Power Pack series comes in various sizes, ranging from 5 kW up to 100 kW so that you can find the right generator for your needs.
Schneider Electric’s Xantrex and PowerOne brands are making a big push into the data center space with their new Schneider Electric XW2 series of inverters. The units offer up to 2MW in power, which means they can be used for both microgrids or as a backup generator in a traditional utility-based system.
The units are based on an innovative “Free Powering” technology that allows them to provide free power for up to five minutes at a time if there is an interruption in the grid. The price point is around $15 million per unit, much less than other options requiring fewer generators to provide the same amount of total power.
4. Bucher Generators
Bucher Industries has been offering its Diesel Generators since 2005, with its current range including 75 kW to 5 MW generators. And while Bucher is best known for its diesel engines, it also offers natural gas and LPG-powered units. Its diesel generators range in price from $30,000 to over $3 million, depending on model and application needs.
5. ABB
ABB is one of the largest electrical equipment manufacturers in the world, and its Power Systems division is a leading supplier of generator sets for data centers.
ABB’s portfolio of generator sets for data centers includes a wide range of products that can meet any application requirement.
The company offers three types of generator sets: diesel-powered, gas-powered, and fuel cell-based. Each type has its own advantages and disadvantages, but all are designed to provide reliable power when needed — during a power outage or other emergency event.
6. General Electric (GE)
GE manufactures several different types of generators, including traditional gas-powered generators and diesel generators that use waste heat to reduce fuel consumption. The company has also developed a hybrid generator that combines natural gas combustion with an electric motor. This reduces emissions by more than 90 percent compared to conventional natural gas generators.
7. Emerson
Emerson develops, manufactures, and services power generation equipment worldwide for industrial and utility customers. Emerson offers a range of products from simple single-phase devices up to large multi-megawatt three-phase units. The company also produces portable generators for emergency backup power applications in residential homes, commercial buildings, and industrial facilities.
8. Baldor Power
Baldor Power Systems designs and manufactures AC drive systems for industrial applications such as manufacturing processes, mining operations, and utility grid management systems. The company provides integrated solutions for application control needs ranging from basic overload protection to complex process control systems.
Conclusion
Generators are an important part of any data center. They not only provide power to the facility but also ensure that your IT equipment continues to operate in case of an emergency or a power outage. That’s why choosing the right generator for your data center is essential.
Diesel generators dominate the European data center market, but natural gas-fired generators are gaining popularity. Natural gas prices are low, and the fuel is easier to get than diesel.
