Deutsche Telekom’s enterprise arm is to overhaul the ICT systems of Generalitat, the government of Catalonia, in a series of deals worth over €400 million in total.

T-Systems has been given a brief to operate Generalitat’s workstation computers and applications, provide user support, network its public administration sites and provide “general” telecoms services and data center infrastructure.

Generalitat said it wanted to reduce the number of ICT service providers it uses from 200 at present to less than 20, streamline its infrastructure and use services based on demand to reduce operating costs.

T-Systems CEO Reinhard Clemens said the deal was one of the biggest the company had won outside Germany.

"The economic situation in European countries is creating a favorable climate for big deals," claimed the CEO.

"When longer-term contracts come up for renewal, more and more large enterprises are looking to move partly over to cloud computing.”

In July, T-Systems signed another big deal with energy giant BP.

The deal is good news the DT subsidiary given it registered a fall in revenues during the first six months of 2012.
