projects Other remarks
1
Up to 50 MW capacity with air/ hybrid cooling; the minimum capacity would be 20 MW. 1
Reduction in water consumption to 25% or less of the benchmark figure of 3000 litre per MWh. Stand alone solar power plant with up to 10% energy from auxiliary source
250 MW capacity with up to 30% gas hybridization 1
Total gas consumption in a year will not be more than 30% of the total generation of the plant based on total units of electricity generated in a year.
350 MW capacity having operating temperature over 500 C 1
Stand alone solar power plant with up to 10% energy from auxiliary source
4Solar Augmentation of the existing coal thermal power plant
To bedecided
Integration Strategy: Solar energy to be added to supply steam to the plant’s cold reheat line and/ or the steam extraction lines for the plant’s feed water heater.· Energy output of the solar plant to be monitored against declared performance.· May be considered under R&D programme to provide capital subsidy.
5Solar - biomass hybrid plant of 1- 3 MW capacity
4 to 5 projects
The turbine capacity to be maximized for solar radiation conditions.· Solar contribution to be over 25%.· The developer to have dedicated biomass supply chain for the project
6
Base load capacity solar stand alone plant of up to 10 MW capacity; the minimum capacity would be 3 MW. 1
The project may have thermal storage for non-solar hours with up to 10% energy from auxiliary source

1. Air cooling
• Up to 50 MW capacity with air/ hybrid cooling; the minimum capacity would be 20 MW.• Reduction in water consumption to 25% or less of the benchmark figure of 3000 litre per MWh.• Stand alone solar power plant with up to 10% energy from auxiliary source
– ACC is a critical technology for CSP, given that water may not be available for all future projects.
– Hence this option must be explored.– Project size may be capped at 50MW, but storage should also be allowed – to take
advantage of lower backpressures at late evenings/night.

2. Gas hybrid
• 50 MW capacity with up to 30% gas hybridization• Total gas consumption in a year will not be more than 30% of the total generation of the plant
based on total units of electricity generated in a year.
– Gas support helps to stabilize the operations of a CSP plant.– This would require a natural gas fired heater in the plant.– But there is no great technology aspect to gas support.– Gas support should be considered for innovative configurations– Gas supply must be clearly provided by government at a fixed price for the duration of the
PPA.

3. Working temp > 500 C
• 50 MW capacity having operating temperature over 500 C• Stand alone solar power plant with up to 10% energy from auxiliary source
– This would mean either:• parabolic trough technology with molten salt as HTF (Archimede) or• power tower technology (SENER, Solar Reserve, BrightSource etc)
– Except SENER none has a commercially operating plant as of today.– Technology risk is significant.
– This option may be clubbed with the option 6 “Base load plant”, to create a project of higher capacity.

Summary
• The Idea of Demo Projects to Introduce/Validate new Technologies is excellent
• Case -1 bidding at present may not yield desired results
• BOT model may be explored
