The Company decided to enter the energy market in 1994 when a new
legal framework was enacted in Greece (L. 2244/94. Rokas' decision
was based on its experience in the construction of wind farms and
hydro plants on behalf of PPC, as well as on the favorable
conditions that existed in the market for the development of
Renewable Energy projects.
The Company was initially engaged in the construction of wind
farms in the early 90’s. Following an international tender, it was
awarded the construction of 5 wind farms for PPC, with a total
capacity of 10.2 ÌW.
Hydro Power Plants and Thermal Power Stations
The Company has also significant experience in the development and
construction of hydropower plants (HPPs). Up to present, it has
undertaken the construction of generators for small and medium
sized HPPs, turbines, gates, gantry cranes and steel pipes. The
projects carried out by the Company include the following:
• Gantry cranes with lifting capacity up to 350Ô for Hydro Power
Plants (HPPs) of PPC.
• HPPs 3x4 MW in Makrohori, Veria, as main contractor for PPC.
• Equipment for the HPPs of Sfikia, Asomata, Aoo, Platanovrisi,
• Combined cycle Thermal Power Station in Lavrion.
Solar – Thermal Energy
The Company showed an early interest in solar energy and
photovoltaic systems. In April 2001, it successfully completed the
construction of a Photovoltaic Park with capacity of 171.6 ÊW, in
Xerolimni (Lasithi), 10 klm southeast of Sitia (Crete), which was
one of the first projects of this scale in Greece.
