Transelectrica announced that it has completed the second stage of the 400/110/20 kV Tulcea Vest substation refurbishment project following a 100 million lei ($25 million/22 million euro) investment. The refurbishment of Tulcea Vest Substation contributes to increasing the operational safety of the national power system in the southeastern area introducing new high-performance equipment, Transelectrica announced in a filing to the Bucharest Stock Exchange, BVB. The refurbishment of the substation was carried out in two stages: the first one between 2013 to 2015 and the second between 2017 to 2018. The 400/110/20 kV Tulcea Vest is an important hub in the power transmission grid, supplying the municipality of Tulcea, the industrial platform that includes alumina refinery Alum Tulcea and Tulcea Shipyard. The investment is part of a larger series of projects that are completed, in execution or are to be started by the company in the Dobrogea area. With a total value of over 390 million lei, the six projects, are meant to increase the operational safety of the national power system and to contribute to the integration of electricity from renewable sources.

In May, the company inaugurated a 400 kV interconnection line between Romania's Resita and Serbia's Pancevo following investment of over 81.5 million lei.

Transelectrica recorded a net profit of 98 million lei in the first half of 2018, flat year-on-year. The financial results were negatively influenced by a 10% drop in transmission prices as compared with the first half of 2017.
