Datacenter Beijing (CHN)

One of Chinaʼs first data center to use trigeneration as main source for power, heat and cooling

Data centers in China usually rely on the grid as the main power source, so using the Jenbacher genset for primary power was a break from tradition. Having worked with Jenbacher products in the past, the customer is confident in the Jenbacher performance and reliability.


The customer’s data center consists of a 31,000-square-meter building, including a 9,000-square-meter energy station. In 2012, the power provider wanted to reduce CO2 and NOx emissions when providing power for the data center in Beijing.


Although the power provider had invested in a number of INNIO* Jenbacher* products in the past, it had never employed trigeneration – the combination of cooling, heat and power – as a facility’s main power source. Providing significant advantages over traditional cooling methods, trigeneration is an excellent solution for sites with fluctuating heating and cooling requirements, offering an efficient year-round source that meets both thermal and cooling power needs. The power provider contracted for five Jenbacher J620 gas generators – four to power the data center and one as backup. The multi-year service agreement will span 59,999 operating hours.


Unlike other traditional Chinese data centers, this project – which was commissioned in 2014 – is not equipped with diesel generator sets as a backup power source. Instead, the Jenbacher gas generators will provide the primary power needs of the site, with the grid supplying backup power as needed. The facility provides reduced CO2 and NOx emissions while demonstrating high energy efficiency, with electrical and heat efficiency totaling 86.7%. In addition, the use of gas generators at the facility supports the local government’s policy to replace coal energy sources.
