A brief presentation of some of our long standing customers.


The Greece-based Centre for Renewable Energy Sources and Saving (CRES) is the Greek organisation for Renewable Energy Sources (RES), Rational Use of Energy (RUE) and Energy Saving (ES).
Founded in September 1987, CRES is a public entity, supervised by the Ministry of Development having financial and administrative independence.

With a scientific staff of more than 120 highly experienced and specialised scientists, and engineers, CRES operates in two main fields of activity:
* As a Research and Technological Centre for RES/RUE/ES, by developing applied research for the new energy technologies and by technically supporting the market for the penetration and the implementation of these technologies.
* As the National Energy Centre, working on energy planning and policy for RES and ES and developing the necessary infrastructure to support the implementation of RES&ES investment projects.

Over the years CRES has participated in more than 600 European, national and international projects. These include applied research projects and development, demonstration projects, energy policy studies, development of energy information systems and energy modelling, investment feasibility studies, technical and economic studies, environmental impact assessments, market research as well as activities for the promotion of RES/RUE/ES. Through these projects, CRES has developed co-operation with numerous public and private organisations, at a national, European and international level.

CRES is a full member of MEASNET.
