  • mtu Series 4000 gas generator sets to provide electricity, heat and cooling for ClusterPower’s Technology Campus in Craiova
  • The completed campus will feature five data centers and provide a significant boost to the region’s global IT infrastructure competitiveness

Rolls-Royce, along with its distributor partner Knopf & Wallisch (K&W), has supplied three mtu customized and containerized combined cooling, heat and power plant (CCHP) trigeneration units to Romanian cloud service provider ClusterPower. They will be used for the efficient and sustainable energy supply at its new technology campus near the southern Romanian city of Craiova, where the IT company will open the largest data center in Romania.

Trigeneration plants are hydrogen-ready

The generator sets are based on mtu 20V 4000 L64 FNER gas engines, which fulfil the strictest emissions standards, allow for quick ramp-up and ramp-down, offer a wide-range of load operations, and high performance also at high temperatures. The gensets are hydrogen-ready, offering the ability to blend 25% hydrogen along with natural gas as the fuel and can even be transformed into a pure hydrogen engine in the future. In this way, they contribute to the reduction of CO2 emissions. This was an important factor for ClusterPower when selecting a partner to supply the energy system for the project.

ClusterPower counts on innovative and environmentally friendly technologies

"We need a very reliable and sustainable solution and a company that is innovative enough to match our ambitions,” said Cosmin Georgescu, CEO of ClusterPower. “Therefore, we are proud of our partnership with Rolls-Royce and the mtu brand. It is a relationship of trust based on common goals like using an innovative and environmental-centric technology for the benefit of our clients. One of the most important values ClusterPower embraces is trust,” added Georgescu. “It is the central element of our relationship with our customers, partners and all those involved in this project.”

First Hyperscale Data Center in South-East Europe

The 273,000-square-metre campus is being built with the aim of increasing Romania’s competitiveness in global IT infrastructure and is the first hyperscale datacenter in south-eastern Europe. (Hyperscale data centers are characterised by the fact that they can be scaled hugely and quickly.). All five data centers are scheduled for completion in 2025. During this time, ClusterPower plans to expand its gas-fired power plant to a total capacity of 200 MW and thus produce its own sustainable electricity.

Sustainable energy concept with combined cooling, heat and power

The first of the five data centers will open its doors in the first quarter of 2022. The mtu CCHP units supply electricity, heat and cooling for the building and the infrastructure. The concept to use the gas gensets as prime power producing electricity while using the main grid as backup is a unique configuration that is currently rarely seen. Guided by ClusterPower’s requests, K&W developed a highly efficient solution to capture most of the exhaust heat from the system with conversion chillers and transform it into chilled air to cool the data center facilities.

“I think that Romania has a lot to say about the European future of innovation and digitalization and we have the opportunity here to develop new infrastructures, using the latest technologies and with modern environmental standards,” said Georgescu. “We are lucky enough to start fresh and we will put this opportunity to good use. It is always nice to know that we have partners ready to support us in our endeavors.”
