Projects Constructed By Our Company BIENTER S.A.
For The GR03 Program - Renewable Energy Sources

map en 


The Programme Area “Renewable Energy Sources (RES) – GR03” aimed at increasing the share of RES in the production and consumption of energy and at the same time the reduction of CΟ2 emissions.
This Programme area had a total budget of 11,188,235 € and was funded by EEA states (Iceland, Lichtenstein and Norway) by 85 % (9,510,000 €) and the Public Investment Program of Hellenic Republic by 15 % (1,678,235 €).
The implemented projects are divided in the below categories:
  • RES in Buildings: The replacement of conventional systems of high energy consumption with RES is funded. RES can include systems as solar systems for hot water, biomass or/and geothermal systems for cooling / heating and PVs (for energy production in buildings).
  • RES applications in microgrids: Microgrids application is funded in central heating systems, biomass and/or geothermic.
  • Replacement of conventional energy sources with RES: Application of RES power plants is funded for supporting “Green Energy installations”, such as pumping houses.

Hybrid geothermal-heliothermal system for the co-generation of thermal and electrical power

BIENTER S.A. and the SPECIAL ACCOUNT OF DEMOCRITUS UNIVERSITY OF THRACE (SA/DUTH) signed two (2) contracts within February and March 2015. The first contract is for the EPC construction of a «Hybrid geothermal-heliothermal system for the co-generation of thermal and electrical power» and the second one for the EPC construction of a «Geothermal fluid pumping and transfer system for district heating».
The above projects will be completed and delivered fully functional to the SA/DUTH within the second semester of 2015.
The two (2) contracts were awarded to BIENTER S.A. after an International Public Open Tender, held in November 2014, in which BIENTER S.A. submitted the most economical and technically robust bids complying with all high level stringent specifications of SA/DUTH, in terms of equipment, facilities and projects’ costs.
Both projects combine two (2) basic energy sources, heliothermal power and geothermal power. More specifically:
  • The heliothermal (CSP) field produces 180kWth of thermal power, includes a thermal storage system and its operation is fully automated.
  • The geothermal field produces 200kWth of thermal power utilizing low depth geothermy.
  • There is electricity production to power all equipment of nearby greenhouses.
  • The produced thermal power will heat greenhouses and an Elementary School building via district heating.

These projects are pilot projects that will be built according to the most recent and stringent technical requirements set forth by both the SA/DUTH and the European Union (Interreg Program) that is co-financing both projects.

BIENTER S.A. and its main shareholders study, develop, design, construct and put into full operation Renewable Energy Sources (RES) projects for thirty-four (34) consecutive years starting in 1981. They have built RES projects like Small Hydros, Biomass and Photovoltaic plants while at the present time they are extending their activities to the new growing areas of Biogas and Solar & Geothermal Systems for both local use and use with the Utility and district heating networks.

Solar Energy and Technologies Fair “Solarex Istanbul” 2014

BIENTER SA through BIENTER ENERJI A.S. participates in the International Exhibition of Solar Energy and Technology, SOLAREX 2014 in Istanbul 11,12 April 2014

Visit in Agritechnica 2013 in Hanover - Germany

BIENTER S.A. team visited the World’s largest exhibition of agricultural machinery in Hanover Germany from 13 to 16 November 2013. The main goal of the visit was the monitoring of the recent developments in biogas and biomass projects. Within this context BIENTER’S team met with engineers from highly specialized companies either in the field of usable feedstock as well as new high yield feedstock mixtures or EPC companies building purely large or purely small projects but in any case projects of high value to price ratio.
