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

BIENTER S.A.
EXPANDS ITS PRESENCE IN THE ENERGY SECTOR BY UNDERTAKING
TWO (2) NEW HELIOTHERMAL AND GEOTHERMAL PROJECTS
FROM THE DEMOCRITUS UNIVERSITY OF THRACE

 

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.
