The lease contract was concluded on a ten-year period.

Hidroelectrica currently has the headquarters in an old building on Constantin Nacu Street, nearby Carol I Boulevard.

Tower Center International has been completed for several years but was subject to various litigations between the developer and the financer.

The building has a lettable area of 22,000 square meters. It was developed by Avrig 35 and later acquired by businesspeople Ioannis Papalekas and Dragos Balteanu, in a EUR50 million deal.
