Nethys SA is a Belgian company that operates in the wireline telecommunications sector and develops renewable energy projects. The company was founded in 2006 and is headquartered in Liège, Belgium. Nethys SA is a subsidiary of Enodia, a public utility company that provides energy, water, and telecommunications services to the Wallonia region of Belgium.

Nethys SA's primary focus is on providing high-speed internet, television, and telephone services to residential and business customers in Belgium. The company operates a fiber-optic network that covers more than 80% of the Wallonia region, providing customers with reliable and fast internet speeds. Nethys SA also offers a range of television packages, including sports, movies, and international channels, as well as fixed-line and mobile telephone services.

In addition to its telecommunications services, Nethys SA is also involved in the development of renewable energy projects. The company has a portfolio of wind, solar, and hydroelectric power projects, which it operates through its subsidiary, Elicio. Elicio is a renewable energy developer that specializes in the construction and operation of wind farms and solar parks.

One of Nethys SA's most significant renewable energy projects is the C-Power wind farm, located off the coast of Ostend, Belgium. The wind farm has a capacity of 325 MW and consists of 54 wind turbines, making it one of the largest offshore wind farms in Europe. Nethys SA owns a 20% stake in the project, which generates enough electricity to power more than 300,000 homes.

Nethys SA is committed to sustainability and reducing its carbon footprint. The company has set a target of reducing its greenhouse gas emissions by 40% by 2030, compared to its 2015 baseline. To achieve this goal, Nethys SA is investing in renewable energy projects and implementing energy-efficient practices across its operations.

Nethys SA is also committed to corporate social responsibility and has implemented a range of initiatives to support the communities in which it operates. The company has a program to support local sports clubs and sponsors several cultural events in the Wallonia region. Nethys SA also supports charitable organizations, including the Belgian Red Cross and the Children's Cancer Fund.

Despite its commitment to sustainability and corporate social responsibility, Nethys SA has faced controversy in recent years. In 2018, the company was embroiled in a scandal involving the sale of its stake in VOO, a cable television operator. The sale was criticized for being undervalued and for benefiting the company's executives rather than its shareholders. The controversy led to the resignation of several top executives and a restructuring of the company's governance structure.

In conclusion, Nethys SA is a Belgian company that operates in the wireline telecommunications sector and develops renewable energy projects. The company is committed to sustainability and reducing its carbon footprint, and has a portfolio of wind, solar, and hydroelectric power projects. Nethys SA has faced controversy in recent years, but remains a significant player in the telecommunications and renewable energy sectors in Belgium.
