Generator Sets for Data Centers

What governs our society today? The speed with which we can obtain information. We also need access to information and all essential data in real time. What does ten seconds mean? An acceptable delay in some cases and an eternity if you're waiting for help after an accident. The same goes for waiting for a web page to load or an online shopping site.

The energy has to stay on! 

If a server crashes because of a simple power failure, the entire company can be paralyzed and those few innocent minutes of interruption can quickly turn into considerable financial losses. The major e-commerce companies are leading the way in the search for solutions to this important problem. Only an infallible electricity supply can handle a volume of data of the utmost importance. Today, all the major international e-commerce companies have powerful generator sets as an emergency power supply to cope with power outages, as unlikely as they may be. The power supply needs to be uninterrupted.

The energy generation industry has adapted itself to the idiosyncrasies of these installations with generator sets that are specifically designed for Data Centers and are sized in accordance with the DCC (Data Centre Continuous) power declaration, 

and that comply with the regulations that govern them. The Uptime Institute is the internationally recognized body that specifies and certifies how the installations of a Data Center should be designed.

 Data Center Series

In a data processing centre (DPC), if the data stored there are critical and vital, the power supply is of paramount importance. That is why GENELEC generator sets designed for these projects are able to incorporate a redundant start-up system: whether electric and hydraulic or electric and pneumatic, that provides a 100% engine start-up guarantee.

Their response is incredibly quick, thanks to their pre-heating resistance with a pump. As the water is kept at a minimum temperature of 40ºC, the generator set is able to start up in just ten seconds. How much are these ten seconds worth to a company whose core business depends on these data being available? Each second it takes for a web page to load can mean losses amounting to billions of dollars for these corporations.

 Today's internet users have at their fingertips absolutely all the purchasing possibilities that a global and hyper-connected market can offer. We need to adapt to this immediate demand by offering information and services without outages. It is a guarantee of quality.

The engine for a DCC application must have an electronic speed regulator so that it can quickly reach opportune voltage and frequency conditions whenever a grid failure demands it has to start-up. Once those parameters have been established, it can maintain them as long as it is operating. 

The data center of Alibaba Group, regarded as the largest online sales group in Asia-Pacific, required a 22 MW standby power supply in the second phase of the project. The aim: to prevent any loss of data and/or functionality of the databases that power the group's online sales portals.

Data centres have seen exponential growth in recent years and this trend continues today. Banks, the entertainment industry, shops and public administration bodies need to digitalize their data and already have their own data centres. In this regard, generator sets make sure that all the data they store there are protected and available.

These data centres consume a considerable amount of energy, not only so that they can operate normally but also to keep the rooms in which they are housed at a temperature required to ensure the optimal technical performance of the servers (20ºC). When sizing of a generator set, it is therefore not enough to only consider factors directly linked to the application. Temperature and altitude also need to be taken into account. The choice of cooling system will also be decisive.

Our technical and sales teams will take each of these factors into account to suggest the most suitable equipment and, if necessary, will suggest remote cooling systems, installed on upper floors or on the roof.

The electricity generation industry has adapted itself to the idiosyncrasies of data centre-specific installations. Generator sets are sized to meet the DCC (Data Centre Continuous) power rating, while complying with the regulations in force. The Uptime Institute, the reference body that defines and certifies the design of installations, categorising them into four tiers: Tier I, II, III, IV. The factor that determines the tier of a facility is precisely the number of emergency and continuous supply sources it has available.
