Overview

Mashav Energia is a Polish renewable energy company operating as a fully integrated independent power producer. It develops, constructs and operates renewable energy assets in Poland, and also trades electricity on the Polish Power Exchange. The company is headquartered in Warsaw, at ul. Zielna 37, and presents itself as a leading supplier of wind energy in the Polish market. Mashav Energia's flagship project is the Potęgowo Wind Farm, described by the company as the largest onshore wind farm in Poland and one of the largest in Europe. The project comprises 98 turbines across two locations in the Pomeranian and West Pomeranian voivodeships, with a total installed capacity of 257 MW and individual turbine capacities ranging from 2.2 MW to 2.75 MW. The overall cost of the project is approximately PLN 1.45 billion. The company also lists the Kanin Wind Farm (8 Nordex N100 turbines, 20 MW, operational since 2011) and the Orla Wind Farm (15 Nordex N100 turbines, 37.5 MW, operational since 2015) as portfolio projects, both of which have been sold. Mashav Energia is fully owned by Zephyrus Wing Energies Ltd., a publicly traded Israeli company listed on the Tel Aviv Stock Exchange under the ticker ZPRS. Zephyrus Wing Energies Ltd. is in turn controlled by the Israel Infrastructure Fund (IIF), an Israeli investment funds group. This ownership structure makes Mashav Energia a subsidiary within a broader Israeli-controlled renewable energy and infrastructure group. The company emphasizes its strong and well-established relationships with large international construction companies, turbine and PV suppliers, law firms and financial institutions active in the Polish market. Its activities span development, construction, operation and electricity trading, positioning it as a vertically integrated player in Poland's renewable energy sector. The company also maintains a public-facing presence through its website, where it publishes environmental impact reports and project documentation, particularly for the Potęgowo project, and provides contact points for residents.

History

Mashav Energia is a Polish renewable energy company that has developed, constructed and operated renewable energy assets in Poland. The company presents itself as a fully integrated independent power producer and a leading developer in the Polish renewable energy sector. Its activities include development, construction, operation of renewable energy assets and electricity trading on the Polish Power Exchange. The company's portfolio has included several wind farm projects. The Kanin Wind Farm, consisting of 8 Nordex N100 turbines with a total capacity of 20 MW, has been under operation since 2011. Mashav managed the construction until the final concession for energy production was obtained, and also handled the negotiation and signature of the PPA/CPA agreement. Mashav, as a partial shareholder, also performed additional TCM services for the project. The Kanin Wind Farm has since been sold. The Orla Wind Farm, consisting of 15 Nordex N100 turbines with a total capacity of 37.5 MW, has been under commercial operation since 2015. It saves approximately 57,400 tonnes of CO2 per annum. Mashav supervised the construction, and the project value amounted to approximately PLN 269 million (EUR 64 million). The Orla Wind Farm has also been sold. Mashav Energia's flagship project is the Potęgowo Wind Farm, which the company describes as the largest onshore wind farm in Poland and one of the largest in Europe. The project includes 98 wind turbines with a total capacity of 257 MW, located in two locations across the Pomeranian and West Pomeranian voivodeships. Individual turbine capacities range from 2.2 MW to 2.75 MW. The overall cost of the project is approximately PLN 1.45 billion. The company provides environmental impact reports and project documentation for the Potęgowo project on its website. Mashav Energia is fully owned by Zephyrus Wing Energies Ltd., a publicly traded Israeli company listed on the Tel Aviv Stock Exchange under the ticker ZPRS. Zephyrus Wing Energies Ltd. is controlled by the Israel Infrastructure Fund (IIF), an Israeli investment funds group. This ownership structure places Mashav Energia within a group with Israeli backing and a focus on renewable energy and infrastructure. The company emphasizes its strong and well-established relationships with the largest international construction companies, turbine and PV suppliers, law firms and financial institutions operating in the Polish market, which it leverages to implement large investments in renewable energy. Its headquarters are located at ul. Zielna 37, Bud C, XII piętro, 00-108 Warszawa, Poland.
