The construction company will hold a majority stake in the newly formed joint venture company, which is called Ortiz Electra and plans to run in tenders for the construction of railways and purifying stations.
In April energy holding Electra announced it plans to build a 100 MW wind power plant in the central part of Bulgaria and has already bought 5000 decares of land.
Electra started its activities in Bulgaria at the end of 2009 and said it had earmarked a total EUR 650 M for the acquisition and development of renewable energy projects in the country.
The investment is to be made over the next four years.
Electra operates wind energy parks with a total capacity of 480 MW in southern Bulgaria, two units for electricity production from biomass with a total capacity of 19 MW and a factory for biofuel with a capacity of 30,000 tons per year.
Grupo Ortiz provides construction services in major infrastructure projects in road, railway and air transport, as well as in industrial and business park projects.
