Solar Thermal Power – Global Status
Dr. Ashvini Kumar
Solar Energy Corporation of India
Steam turbines are the dominant power house
354MWe “SEGS” plants going strong after 20 years
1.5 MW Capacity plant at Murcia, Spain
(Air cooling system is used)
Must be scalable and replicable
Must reach early cost competitiveness with the conventional power generation and easy dispatchability.
Reduction in water usage as good DNI areas may not blessed with water availability
Building provision of thermal storage
Global Efforts for development of Large scale CSP projects
Base load CSP power plant – Gemasolar (Power tower, 19.9 MW, Spain)
CSP with storage – up to 7 or 8 hours is considered commercial (several in Spain)
Dry cooling CSP power plant – Puerto Errado I (Linear Fresnel, 1.5 MW, Spain)
High operating temperatures – Gemasolar (Power tower, 19.9 MW, Spain), PrioloGargallo (Parabolic troughs; 5 MW, Italy)
Gas hybridization – all Spanish CSP plants (> 800 MW operational)
Coal augmentation – HassiR’mel (Argelia), Al Kuraymat (Egypt), Ain BeniMathar (Morocco) (parabolic troughs)
Stirling Engines – Maricopa (1.5 MW, USA), Spain (several locations), Portugal (Government CSP demonstration projects in several locations)
Large scale CSP projects
1,000 MW capacity Grid Solar Power Projects
A provision of 500 MW capacity of Solar Thermal power was made.
2.5 MW capacity solar tower project installed, and 7 projects of aggregate capacity of 470 MW are under implementation having time for completion till May 2013.
Some pilot projects are proposed, besides R&D efforts to develop the test and simulation infrastructure.
Parabolic Trough Field
8700 sq. m (3.3 MWth)
Linear Fresnel Field
7200 sq. m (2.2 MWth)
Turbine operating conditions:
saturated steam at 350 deg. C and 40 bar
1 MW with 16 hour thermal storage Project at Mount Abu By WRST with co-funding from Indian and German Ministry
