mtu supplies tailored emergency power solutions
Turkey’s end users primarily need gensets which deliver between 800 kVA and 3,075 kVA. And they have a high opinion of mtu as a systems provider for custom-tailored emergency power products. The Turkish Electricity Transmission Company estimates that the annual rise in electricity demand between 2009 and 2023 is likely to be around 6%. The target is 125,000MW of installed power. For comparison, in 2010, the total was still 54,423MW. The power supply problem is most acute in Istanbul where most of the foreign companies in the country have established locations. The city is home to one fifth of the nation’s population — who use telephone, television and Internet services provided by Türk Telekom. That is why, in July 2011, when it needed to replace the existing emergency power gensets at its Istanbul anatolian side headquarters, the company decided to update and cater for the increasing energy demand by installing three Type DS 2595 D5S emergency gensets from mtu. They are powered by three mtu Type 16V 4000 G63 diesel engines which produce 5,190 kVA of electric power.
Complete solution from a single source A market demand analysis for the Turkish communications network had already been conducted. “We chose the more powerful units to make sure we are well prepared to meet future demand,” said Ali Aydın, Senior Energy Manager at Türk Telekom. Istanbul-based mtu Turkey was able to use its experience as a systems provider to completely equip the 144 square meters underground facility, supplying everything from gensets through switch cabinets to electrical plant. The gensets were built at mtu’s headquarters in Friedrichshafen, Germany, and Aydın has confidence in the emergency supply units from mtu: “They have been running without any sort of problem at all, right up to the present. I can recommend the gensets and the fast and thorough implementation of the project without hesitation.” One of mtu’s special services is to ensure that the manager receives an SMS as soon as a power outage occurs and the gensets have started up.
In the hotly contested private telecommunications market, it is vital for Türk Telekom to be able to provide uninterrupted service for its customers. That is why, before the units were dispatched to Istanbul and went into service, mtu subjected them to comprehensive and thorough tests involving simulated load imposition on its own highly modern test stands at its headquarters in Friedrichshafen.
More powerful emergency gensets guarantee continuous data flow
The gensets run in parallel and each can serve as a back-up for the other. Their high torque means the engines have rapid and high load imposition capability and can achieve operating status, stable voltage and frequency, within nine seconds. Load can be imposed from this point on. Türk Telekom’s central facility needs around 2,200 kVA of energy per hour. 33% of Turkey’s Internet volume emanates from here. The station is Türk Telekom’s third biggest in the country and the company has a total of around 5,000 individual stations which are gradually allowing it to adapt to the ever expanding telecommunications scene — using more powerful emergency gensets. Of course, it is not only private use of the telephone, GSM, web-TV and Internet services which is growing. Service systems such as banks, the education authorities, the police and other security services are also connected. The consequences of a loss of systems data for Türk Telekom’s customers are unimaginable.
mtu — not a one-off solution
Türk Telekom’s use of emergency power technology from mtu is not limited to Istanbul. Also at its location at Erzurum in the east of the country the company has installed diesel gensets from mtu, this time two gensets with Series 2000 engines.
