After comparison of several solar technologies, the solar parabolic dish technology has been found most suitable for our purposes. New designed 50m2 prototype
The main advantages of the 60m2 parabolic dish with fix focus are:
- Cost effective / high output
- Relatively simple construction, modular design
- Innovative thermal storage concept
- Easy operation/ maintenance; all components available
in India
- Inexpensive planar mirrors and MC-controlled tracking system
- Fixed receiver with no need for flexible high pressure joints
- No vacuum technology and no metal glass sealing
- Due to direct steam generation, no heat exchanger and low parasitic loads
- Efficient use of land; the dishes can be tightly placed
- Power on demand and high efficiency due to cogeneration
It is intended to set up the innovative solar thermal power plant based on the newly developed 60m2 parabolic dish with 16 hrs steel core cavity receiver and storage for continuous operation with the following main technical specifications. First test of focus size and receiver
Number of dishes : 770 nos. of 60m2
Electrical output : 1,0 Mw el. (net. 22000 kwh/24hrs)
Thermal output : 150 Mwh th. (24hrs)
Solar field : 25 Acres near to campus (1.3 km)
Total mirror area : 45.000 m2
Turbine : 1,0 Mw el.
3) Timetable
The time frame for completion of this project is two years. The project will be executed in two phases:
Phase I: Simulation and planning for the power plant
Phase II: Procurement and installation of the 1,0 Mw el. power plant
01.2011 - Start of the project
02.2011 - Purchasing of components
03.2011 - Fabrication and installation
01.2013 - Test and commissioning
01.2013-01.2014 - Evaluation, report preparation
4) Budget
The budget for the project is 66 Crs Indian Rupees (~11 Mio. Euro) excluding cost of land. The WRST request for funding with the Indian Ministry of New and Renewable Energy Sources (MNRE) has been approved. The German Ministry for Environment, Nature Conservation and Nuclear Safety (BMU) is considering to support this project.
