About us
Our operations in Poland date back to 1976, when Zakład Wykonawstwa Sieci Elektrycznych Rzeszów (ZWSE Rzeszów) was established. In 2022, the company was rebranded as GRINEA.
For nearly five decades, we have been delivering infrastructure projects that improve the quality of life and support the development of communities.
GRINEA safely and responsibly delivers large-scale energy infrastructure investments, creating long-term value for clients in Poland and the Kingdom of Saudi Arabia.
Since our inception, we have been guided by the principles of integrity, responsibility and respect. Our global mindset, commitment to innovation and continuous pursuit of excellence enable us to successfully deliver ambitious projects while building long-term relationships with our business partners and employees.
