INDIA ONESolar Thermal Power PlantKey Features:

CHP Co-gen plant

Indigineously developed 60 sqm size fixed focus paraboloidal reflector for solar energy

Static cast Iron cavity shape receivers integrated with thermal storage for continuous 24

Hr. operation

Direct generation of super heated steam on demand water as HTF

Co-generation (hot water generation) for efficient usage of thermal energy.

Ideal Combined Heat and Power

CSP technology for India

Present Scenario and challenges in Solar Reflectors: Need for relatively simple modular design / less structural

complexities

Need for Indigenous manufacturing, capacity building and

technology transfer to Industry.

Cost effective technology

Should be easy in operation/ maintenance by means of readily

available spares

Easy to replicate, decentralized fabrication process to create localemployment

Standardization of the technology

The static cavity Receiver: Thermal storage option

Thermal energy storage (250 deg. C to 500 deg. C)

Direct steam generation of high quality saturated and

super heated steam Robust , easy to operate Receivers using metal as thermal

storage

Local manufacturing and cost effective design to suit

Indian conditions (Approximate 25 USD/KWH thermal)

Operational flexibility and low maintenance cost

Low parasitic load due to direct steam generation

Thermal storage for 24 hours using locally available

materials

Standard components to minimize thermal losses from

the Receiver

Avoids high pressure flexible joints.

Steam and hot water generation on demand, 24/7

availability

Antireflection glass at the receiver for minimizing thermal

losses

Long life cycle Approximate 25 years
