AORA Solar has announced that it has completed construction on its second gas turbine solar thermal power station. The station, built in Almeria, Spain, is now undergoing commissioning and certification and is scheduled to begin regular power generation early this year.
The first AORA power station was constructed in Kibbutz Samar, Israel.
In addition to producing electricity, the Almeria plant also produces 170 kW of heat as a byproduct, which will be used to power a desalination plant. The station was constructed over a period of seven months, and is designed for a minimum economic lifespan of 25 years.
AORA's innovative energy generating system is designed to require less land and less water while generating more usable power and heat than other solar energy systems.
The company's revolutionary hybrid approach enables the system to run not only on solar radiation, but on almost any alternative fuel as well, including biogas, biodiesel and natural gas.
This enables a variety of operation modes - from solar-only mode, where electricity is supplied from ample sunlight, to hybrid-mode, where fuel helps generate electricity when sunlight is insufficient, such as when it is cloudy, to fuel-only mode during night hours or heavily overcast periods, thereby guaranteeing an uninterrupted power supply 24 hours a day.
The station's modular approach offers wide implementation options, allows for construction in scattered locations and on sloped land, places less stress on the energy grid and provides customers with the ability to finance installations in stages.
"We are very excited to complete construction on our second power station, and we look forward to demonstrating our unique ability to provide our customers with uninterrupted, 24/7 clean-power," said Zev Rosenzweig, AORA's CEO.
"Our technology and scalable solution can be easily customized for a variety of applications and environments and I believe this demonstration unit will be quickly followed by additional installations in Spain and around the world."
AORA's Almeria power station is situated on half an acre of land in Platforma Solar Almeria, the world's largest and most exclusive science park dedicated solely to the research and development of solar-based power-generating systems. The plant consists of a field of 52 tracking mirrors (heliostats).
Each heliostat follows the sun and directs its rays towards the top of a 35 meter-high tower housing a special solar receiver along with a 100kWe gas turbine.
The patented receiver uses the sun's energy to heat air to a temperature of 1,000 degrees Celsius and directs this energy into the turbine. The turbine then converts this thermal energy into electric power.

Solar Array at Neuse River Wastewater Treatment Plant Energized
Raleigh NC (SPX) Jan 06, 2012
The 1.3 megawatt solar voltaic array at the City of Raleigh's Neuse River Wastewater Treatment Plant was energized in December. The 10-acre site is located at the intersection of Battlebridge Road and Brownfield Road. The arrangement between the City of Raleigh, Progress Energy Carolinas, Southern Energy Management, and NxGen Power reaffirms the City's commitment to being a leader in the c ... read more
