Through its co-operation with many entities (companies, university and other institutions), ROKAS researches new RES technologies. The results of this research are of utmost importance considering Greek standards.

1999
Development of wind farm tele-control software from the PPC Centre of Load Distribution (CLD) in Crete.
Collaborating entities: C. ROKAS SA, AMBER SA, ΚΚ Electronic A/S
This software is the principal one used by (CLD).

Development of software for handling any visual/sound disturbances in wind farms.
Collaborating entities: C. ROKAS SA, National Technical University of Athens (NTUA).

2000
Development of software based on the 3-D Navier-Stokes connecting code, for the solution of the airflow field in complex terrain.
Collaborating entities: C. ROKAS SA, National Technical University of Athens (NTUA)

Development of MCP software for the determination of long-term wind characteristics in complex terrain.
Collaborating entities: C. ROKAS SA, National Technical University of Athens (NTUA), Center of Renewable Energy Sources (CRES).

Al software developed in collaboration with the NTUA has already been certified in operating wind farms.

2001
Installation of an experimental electric energy producing photovoltaic plant 171,36 KW in Sitia, Crete. The photovoltaic plant consists of 1428 photovoltaic modules SOLAREX MSX-120.
Collaborating entities: C. ROKAS SA, DISIOS SA, Ministry of Development.

Participation, in collaboration with CRES, in a research program for the design and construction of two systems combining the operation of wind turbines and hydrogen cells. (Storage of electric energy / production of hydrogen)
Collaborating entities: C. ROKAS SA, CRES and foreign entities.

2002
Installation of experimental aerodynamic arrangements (dinotails & trimstalls) on wind turbine blades (Antia wind farms), for the improvement of the capacity factor in complex terrain. Collaborating entities: C. ROKAS SA, BONUS energy A/S, LM Glassfiber A/S

Construction of an on site workshop for the repair of wind turbine blades at the Skopies wind farm in Zarakes, Evia.
Collaborating entities: C. ROKAS SA, LM Glassfiber A/S

2003
Experimental installation on the Leros wind farm, of the InmarSat BGAN arrangement, satellite data transmission system in Denmark.
Collaborating entities: C. ROKAS SA, BONUS energy A/S, KK Electronic A/S

2004
Research on the development of software for the short term wind energy forecasting in complex terrain.
Collaborating entities: C. ROKAS SA, Inflow O.E.

Study for the radio conversion of the all wind farms telecommunication system, with the development of microwave on site transmitters-receivers for the attainment of data transmission at high speed (128Kbps) both within and out of the wind farm area.
Collaborating entities: C. ROKAS SA, OTE – Department of Development & Planning, LANNET S.A.

2005
In November 2005, the first pilot plant hydrogen producing hydrogen from wind energy was inaugurated in Greece within the framework of a research project of the European Union. From the Greek side, the Company participated in the design and realization of the project in association with the Center for Renewable Energy Sources.

The aim of the project is to design, install and study two systems that will combine wind energy with hydrogen technologies under real conditions. One of these systems will be installed in Spain (Canary Islands) and the second one has already been installed and operating since November 2005 in Greece, in the wind farm of the Center for Renewable Energy Sources (CRES) in Lavrion. CRES, which co-ordinates the activities in the Greek testing field in cooperation with C. Rokas SA and a Cypriot entity, has designed, installed and now is studying the operation of a production, condensation and bottling system for hydrogen under variable power conditions.
