The two pioneering projects – the hybrid solar and wind farm in Beştepe, Tulcea County, and the hybrid power plant with storage installed in Cluj-Napoca – meet Romania’s ambitious targets for decarbonization and innovation in the renewable sector.

In Tulcea County, Parapet built a photovoltaic plant with a total capacity of 1.1 MWp, installed inside the Beştepe wind farm. It is the first hybrid renewable power generation project in the country, according to Transelectrica data, and involved the installement of 2,652 photovoltaic panels close to the wind turbines functional since 2014. The total installed capacity of the mixed plant currently amounts to 7.25 MWp, the system ensuring a total annual production of 24 GWh and contributing to the reduction of CO2 emissions by 20,400 tons/year.

“Due to hybridization, the installed capacity leads to less variations in the power generation process, to a better use of transmission and distribution systems and, implicitly, to maintaining the stability of the grid.”, Andrada Moldovan declared, CEO Parapet.

In Cluj, Parapet has completed works on a new mixed wind-photovoltaic power plant with a total capacity of 1 MWp, the second of its kind installed by the company in Romania. The project is used for research and includes an energy storage system with a capacity of 110 kW. The hybrid park is, in fact, a research laboratory for testing in real conditions the energy efficiency produced by photovoltaic panels and modern wind installations.

In addition to the wind turbine and storage system (100 KWh lead-acid batteries and 10 KWH Li-Ion batteries), the hybrid park involved the installation of 1,730 photovoltaic, monofacial and bifacial panels, installed on three types of structures:
– Photovoltaic panels installed on fixed structure, 390 kW
– Photovoltaic panels installed on Carport structure, 400 kW
– Photovoltaic panels installed on self-tracking systems, 200 kW

The energy produced will ensure the partial electricity consumption of Cluj Innovation Park, for non-commercial purposes, as well as the consumption of two charging stations of 60 and 150 kW, also used to supply electric buses used for public transport in the area. Thus, the project will contribute to the development of a smart microgrid for electricity distribution, generation, and storage.
