Hydropower in India: Value Chain, Economics and Companies to Track
In the first article of this series, we studied the complete value chain of India’s power sector.
In Part 2, we analysed thermal power—its value chain, economics and participating companies.
Now, in Part 3, we move to hydropower.
At first glance, hydropower looks like a simple business: build a dam, store water and generate electricity.
But from an investor’s perspective, the sector is more complex.
Hydropower includes three different businesses:
- Conventional large hydro
- Small hydro
- Pumped-storage hydropower
Each has a different business model, risk profile and role in India’s electricity system.
1. Hydropower Is Not One Business
Conventional Large Hydro
Large hydro projects have a capacity above 25 MW.
These projects generate electricity using natural river inflows and stored water. They can broadly be divided into:
- Reservoir or storage projects
- Run-of-river projects
- Run-of-river projects with pondage
Reservoir projects can store water and generate electricity when demand is high. Pure run-of-river plants have less flexibility because their generation depends more directly on river flows.
Small Hydro
Small hydro includes projects with a capacity of up to 25 MW.
These projects are generally developed near smaller rivers, canals and regional water systems. They require lower investment than large dams but remain dependent on local hydrology, evacuation infrastructure and power purchase agreements.
Pumped-Storage Hydropower
Pumped-storage projects, or PSPs, operate differently.
When electricity is cheap or available in excess—usually during solar-generation hours—the plant uses that electricity to pump water from a lower reservoir to an upper reservoir.
When electricity demand increases, the stored water is released to generate power.
Therefore, pumped storage does not create new primary energy. It stores electricity and shifts it from one period to another.
That distinction is extremely important for investors.
2. India’s Hydropower Capacity
As of 31 July 2026, India had approximately 57.25 GW of total hydropower capacity.
However, this number includes both electricity generation and storage assets.
The correct breakdown is:
| Segment | Operating capacity | Primary role |
|---|---|---|
| Conventional large hydro | 44.64 GW | Renewable electricity generation |
| Pumped storage | 7.43 GW | Electricity storage and grid balancing |
| Small hydro | 5.18 GW | Decentralised renewable generation |
| Total hydro family | 57.25 GW | Generation plus storage |
India’s entire installed power capacity stood at approximately 551.99 GW. Hydropower therefore represented around 10.37% of total installed capacity.
The important point is that the entire 57.25 GW should not be treated as conventional electricity-generation capacity because pumped storage is primarily a storage asset.

3. India Has Developed Only One-Third of Its Hydro Potential
According to the Central Electricity Authority, India has approximately 133.41 GW of exploitable conventional large-hydro potential.
Against this potential, only around 44.64 GW was operational as of July 2026.
This means India has developed approximately 33.46% of its identified large-hydro potential.
The biggest opportunity lies in the North-Eastern Region.
The region has around 55.93 GW of exploitable potential, but only approximately 3.02 GW was operational. That means just 5.4% of its potential has been developed.
This looks like a large opportunity, but there is a catch.
North-Eastern hydro projects usually require:
- Large civil construction
- Roads and transmission infrastructure
- Forest and environmental approvals
- Rehabilitation and resettlement
- Community participation
- Long-term project financing
Therefore, identified potential should not be treated as immediately executable capacity.
A project can remain at the survey, DPR or approval stage for many years before construction begins.

4. Understanding the Hydropower Value Chain
The hydropower value chain begins much before electricity generation.
The complete chain is:
Site identification → Survey and DPR → Land and environmental approvals → Roads and transmission infrastructure → Civil construction and tunnelling → Turbines and generators → Commissioning → Power or storage contract → Operations and maintenance
Different companies participate at different stages.
Project Developers
Developers identify projects, arrange approvals and financing, appoint contractors and operate completed plants.
Civil and EPC Contractors
These companies construct dams, tunnels, underground caverns, powerhouses, roads and water-conveyance systems.
Equipment Manufacturers
They supply:
- Hydro turbines
- Generators
- Reversible pump-turbines
- Generator-motors
- Control systems
- Gates and hydro-mechanical equipment
Transmission Companies
Large hydro projects are often situated far from major consumption centres. Dedicated transmission infrastructure is therefore necessary to evacuate electricity.
Power Purchasers
Electricity is sold to state distribution companies, power-trading companies or other contracted buyers.
In pumped storage, the buyer may pay for storage capacity rather than only purchasing electricity.
5. Why Hydropower Becomes More Important as Solar Grows
India is rapidly adding solar and wind capacity.
Solar produces most of its electricity during the daytime. However, electricity demand often remains high during the evening, when solar generation falls.
This creates a balancing requirement.
Reservoir hydro can preserve water and generate during higher-demand periods. Pumped storage can use surplus daytime electricity to pump water and release it during the evening peak.
Hydropower can also provide important grid services such as:
- Frequency regulation
- Spinning reserves
- Voltage support
- Grid inertia
- Black-start capability
The CEA’s generation-adequacy plan for FY2035-36 models an electricity system containing:
- 509 GW of solar power
- 155 GW of wind power
- 78 GW of large hydro
- 6 GW of small hydro
- 94 GW/567 GWh of pumped storage
This explains why pumped storage is becoming one of the most important emerging areas within the power sector.

6. How Conventional Hydropower Companies Make Money
Many large hydropower projects operate under a regulated tariff structure.
The tariff generally has two components:
Capacity Charge
This helps the company recover a portion of its annual fixed costs based on plant availability.
Energy Charge
This is linked to scheduled electricity generation and the plant’s design energy.
Under the CERC Tariff Regulations, 2024, hydropower projects generally have a useful life of around 40 years for tariff purposes.
This creates the possibility of long-duration and relatively visible cash flows after successful commissioning.
However, returns depend on several factors:
- Approved project cost
- Time taken to complete construction
- Regulatory approval of cost overruns
- Water availability
- Plant availability
- Silt-related shutdowns
- Power purchaser’s payment record
A higher project cost does not automatically create more value. If the regulator considers part of the expenditure inefficient, that amount may not be fully allowed in the tariff.

7. Pumped-Storage Economics Are Contract-Driven
For pumped-storage projects, headline capacity in MW is not enough.
Investors must also examine:
- Storage capacity in MWh or GWh
- Number of storage hours
- Round-trip efficiency
- Expected cycles
- Charging-power cost
- Transmission charges
- Contracted capacity
- Tariff structure
- Contract duration
A 1,000 MW project providing six hours of storage is economically different from a 1,000 MW project providing eight hours.
There are two important contract structures.
Tolling Model
The buyer generally supplies or arranges the charging electricity. The developer earns a storage or capacity charge.
This can reduce exposure to electricity-price fluctuations for the developer.
Composite-Tariff Model
The developer arranges the charging electricity and supplies stored electricity at an agreed tariff.
In this model, the developer carries greater charging-power and market risk.
Therefore, two physically similar pumped-storage projects can generate very different returns depending on their contracts.
8. India’s Pumped-Storage Pipeline
As of July 2026, India’s pumped-storage development pipeline included approximately:
- 7.43 GW in operation
- 15.87 GW under construction
- 10.40 GW appraised or concurred but not under construction
- 94.50 GW under survey and investigation
The CEA’s adequacy plan models 94 GW/567 GWh of pumped storage by FY2035-36.
A separate CEA roadmap envisages cumulative pumped-storage capacity of approximately 105.56 GW by FY2035-36.
These numbers indicate the direction of the opportunity, but they should not be treated as guaranteed capacity additions.
Projects at the survey, MoU or initial-development stage may still require:
- Final site selection
- Detailed project reports
- Environmental approvals
- Land acquisition
- Power or storage contracts
- Financial closure
- EPC mobilisation
The research approach should therefore be simple:
Operating projects first → Under-construction projects second → Contracted projects third → Survey and MoU projects last

9. Listed Companies Participating in Hydropower
The following companies have different levels of participation in India’s hydropower value chain.
NHPC
NHPC is the clearest listed exposure to operating large hydropower.
As of June 2026, the company reported approximately:
- 8,771 MW of operating hydropower
- 8,014 MW of projects under construction on a consolidated gross basis
- A significant pumped-storage development pipeline
Investors should monitor Subansiri Lower commissioning, Dibang construction, project costs, regulated-equity growth, hydrology and receivables.
SJVN
SJVN reported approximately 1,972 MW of operating hydropower.
Its pipeline includes projects in India and Nepal, along with pumped-storage opportunities.
Important variables include the execution of Arun-3, Luhri, Sunni and Dhaulasidh projects, project funding and hydrology.
NTPC Group
NTPC’s hydropower exposure comes through its own projects and group companies such as THDC India and NEEPCO.
The group reported around 4,725 MW of gross operating conventional hydro and pumped-storage capacity, along with a sizeable construction and development pipeline.
The NTPC group is a diversified power-sector exposure rather than a pure hydropower company.
JSW Energy
JSW Energy operates approximately 1,781 MW of hydropower capacity.
The company is also developing a large pumped-storage portfolio, making it an integrated renewable-energy and storage platform.
Investors should track project-level contracts, storage duration, capex, financing and construction timelines.
Tata Power
Tata Power has around 880 MW of domestic hydropower capacity.
Its pumped-storage plans include the Bhivpuri and Shirawta projects in Maharashtra.
The company also has hydropower exposure through projects and partnerships in Bhutan.
Adani Green Energy
Adani Green has reported a developing pumped-storage portfolio.
The important factors are the conversion of announced capacity into approved projects, signed storage contracts, financial closure, construction and commissioning.
Investors should not automatically treat every group-level MoU as capacity belonging to the listed company.
Torrent Power
Torrent Power is implementing the 3,000 MW Saidongar-I pumped-storage project, with indicative investment of around ₹14,000 crore.
Key monitoring areas include environmental approvals, EPC progress, project financing and storage-agreement economics.
Jaiprakash Power Ventures
Jaiprakash Power Ventures operates the 400 MW Vishnuprayag run-of-river project.
Its hydropower exposure is more concentrated than that of diversified utilities.
NLC India
NLC India has early-stage pumped-storage opportunities but does not currently have a major operating hydropower portfolio.
Its projects should be treated as development optionality until approvals, contracts and construction milestones are visible.
10. Equipment and EPC Companies
Investors can also participate in hydropower growth through execution companies.
BHEL
BHEL supplies turbines, generators, reversible pump-turbines and generator-motors.
Its hydropower opportunity depends on:
- New equipment orders
- Domestic manufacturing
- Project execution
- Milestone billing
- Working-capital management
Larsen & Toubro
L&T participates in civil construction, tunnelling and hydro-mechanical EPC work.
It has received orders connected with major pumped-storage projects.
However, project capacity awarded by a customer should not be counted as capacity owned by L&T.
Patel Engineering
Patel Engineering has significant exposure to hydro and pumped-storage civil construction.
For EPC companies, a large order book is only the starting point. Investors must also examine margins, geological risks, claims, project certification, receivables and cash conversion.
11. Major Risks in Hydropower
Hydropower projects can create long-duration assets, but they also carry some of the power sector’s toughest execution risks.
Geological Risk
Unexpected rock conditions, tunnel collapse or water ingress can delay construction and increase costs.
Hydrology Risk
Lower rainfall and river inflows can reduce electricity generation. Extreme floods can damage operating assets and access infrastructure.
Silt Risk
Sediment can damage turbines and force seasonal shutdowns, particularly in Himalayan projects.
Environmental and Social Risk
Forest approvals, land acquisition, rehabilitation and local opposition can delay projects.
Cost-Overrun Risk
Long construction periods increase interest during construction and project costs.
Contract Risk
In pumped storage, weak tariff terms or expensive charging power can reduce returns.
Transmission Risk
A completed plant cannot operate effectively if the required transmission infrastructure is delayed.
Battery Competition
Falling battery-storage costs can affect the competitiveness of uncontracted or expensive pumped-storage projects.
12. What Investors Should Track
Before valuing a hydropower company’s pipeline, investors should ask:
- Is the project operating, under construction or only announced?
- Does it have environmental and forest approvals?
- Has the company signed a power or storage agreement?
- Has financial closure been completed?
- What is the latest estimated project cost?
- How much capex is still pending?
- What is the expected commissioning date?
- Who bears the cost of charging power in a PSP?
- What are the storage duration and efficiency?
- Is the reported capacity gross or attributable to the listed company?
- What is the plant’s generation compared with design energy?
- How strong is the company’s cash flow and balance sheet?
The biggest mistake is to assign the same value to operating capacity, construction capacity and MoU-stage capacity.
They are not equal.
Conclusion
Hydropower is entering a new phase in India.
The old hydropower story was mainly about generating renewable electricity from rivers and dams.
The new story is broader:
Generation + Peak supply + Grid stability + Long-duration energy storage
Conventional hydropower can provide long-life regulated assets, while pumped storage can become critical for balancing India’s growing solar and wind capacity.
But the opportunity is highly project-specific.
The correct analytical hierarchy is:
Operating cash flow → Contract quality → Construction progress → Project cost → Hydrology → Financing → Early-stage pipeline
For developers, successful commissioning and tariff quality matter more than announced capacity.
For EPC companies, order execution and cash conversion matter more than the total MW of customer projects.
