Power and automation technologies provider ABB said Wednesday it has signed operation and maintenance (O&M) contracts for four photovoltaic (PV) parks with a total capacity of 85 megawatts-peak (MWp) in Bulgaria.
Owned and built by Hareon Solar, a leading Chinese-based manufacturer of PV modules and a major investor in PV power plants in Bulgaria, the solar plants covered by the contracts are located in the municipalities of Pleven, Kazanlak, Karlovo and Silistra, in northern and central Bulgaria, ABB said in a statement.
A control center in the capital city of Sofia will monitor the operation of the four facilities tracking and securing performance of the main equipment. A crucial part of this function includes the optimisation of plant operations, analysis, diagnosis and emergency repair of faults, and telephone support.
Hareon Solar's 50.6 MWp Pobeda, 25 MWp Cherganovo, 5.0 MWp Karlovo and 5.88 MWp Kolarovo PV solar plants use ABB solar equipment, including PVS800 inverters, dry cast-coil transformers and medium-voltage switchgear, as well as monitoring and control systems.
ABB has cooperated with Hareon Solar since 2011 in the construction of solar parks in Italy and Bulgaria. ABB has more than 1,000 employees in Bulgaria and three production units are located in Petrich, Sevlievo and Rakovski.
