🌍 INTRODUCTION
Not Just Solar Generation. Solar You Can Schedule.
Solar PV changed how electricity is generated.
But it did not solve when electricity is needed most.
Evenings, peak hours, weak grids, industrial heat demand—
these still rely heavily on fossil fuels.
Greentech Solar Thermal exists to close this gap.
This is not just solar generation.
This is dispatchable renewable power—day and night.
By storing the sun’s heat instead of electricity, Greentech Solar Thermal converts sunlight into schedulable, dependable power, capable of replacing fossil peaking plants.
🏢 POSITIONING WITHIN Greentech Group
Greentech Solar Thermal is a core subsidiary of Greentech Group, strengthening the Renewable Energy & Storage vertical with round-the-clock solar power.

Strategic Mandate
⚙️ Grid-friendly, dispatchable solar energy
🧱 Long-life infrastructure assets (30–40 years)
⚡ Fossil-free replacement for evening & peak demand
🔗 Bridge between solar abundance and grid reliability
➡️ When the sun sets, stored heat still generates power.
🔥 WHY SOLAR THERMAL (CSP) MATTERS FOR INDIA
India’s power challenge is no longer capacity—it is timing and stability.
Solar PV peaks at noon.
Demand peaks after sunset.
CSP with thermal storage uniquely solves this mismatch.
What Makes Solar Thermal Strategic
Stores energy as heat, not electricity
Delivers power after sunset
Operates like a conventional thermal plant—without fuel
Provides inertia and grid stability
Scales to utility-grade capacities
Solar thermal is not a competitor to PV.
It is the missing reliability layer.
⚙️ HOW CSP + THERMAL STORAGE WORKS
Mirrors concentrate sunlight onto a receiver
Heat is captured in molten salt or advanced thermal media
Stored heat is released to produce steam
Turbines generate electricity on demand—day or night
This creates solar power with memory.
🎯 CORE FOCUS AREAS
(What Greentech Solar Thermal Builds)
☀️ 1. CONCENTRATED SOLAR POWER (CSP) PLANTS
Tower & parabolic trough systems
Utility-scale plants (50–200 MW)
Designed for high solar-irradiation regions
CSP plants function like solar thermal power stations, not intermittent generators.
🔋 2. THERMAL ENERGY STORAGE SYSTEMS
Molten salt storage (6–12+ hours)
Advanced heat-storage media
Multi-cycle daily dispatch capability
This allows solar power to be scheduled like coal or gas.
🌙 3. NON-INTERMITTENT SOLAR ELECTRICITY
Evening and night-time generation
Peak-load support
Reduced curtailment of solar PV
Solar becomes firm power, not variable power.
⚡ 4. PEAK-LOAD & EVENING DEMAND SUPPLY
Solar thermal replaces:
Gas-based peaking plants
Diesel generators
Coal-based evening ramp-up
This directly cuts emissions during most polluting hours.
🏭 5. INDUSTRIAL HEAT + POWER APPLICATIONS
Solar thermal delivers:
Process heat for industries
Combined heat & power (CHP)
Decarbonisation of thermal loads
Industries finally get clean heat, not just clean electricity.
🔄 6. HYBRID INTEGRATION (PV + CSP + STORAGE)
Greentech Solar Thermal integrates with:
Solar PV parks
Hybrid renewable clusters
Pumped hydro & storage systems
This creates fully dispatchable renewable hubs.
📜 7. LONG-TERM PPAs WITH DISCOMs & PSUs
25–30 year PPAs
Peak & firm power contracts
Grid-support & capacity payments
Solar thermal becomes a bankable infrastructure asset.

👤 FOUNDER’S DISPATCHABLE SOLAR VISION
Sunil Kumar Singh
“The future of solar lies not only in generation,
but in the ability to store and deliver power when needed.”
Greentech Solar Thermal reflects a long-term belief:
Energy must be predictable
Renewables must replace thermal power, not just supplement it
Infrastructure must serve the grid—not stress it
This is solar with responsibility.
🧠 UNIQUE STRATEGIC USP (WHY GREENTECH SOLAR THERMAL WINS)
True Dispatchability – Solar power available on demand
Thermal Storage Advantage – No battery degradation
