India’s Small Hydro Power Scheme: What It Means for EPC

India’s renewable energy transition is entering a phase where solar and wind are no longer the only technologies receiving significant policy attention.

‍

Small hydropower is returning to the infrastructure conversation.

India’s large untapped potential, combined with the new government development scheme, could increase investment in new projects, modernization, canal-based hydropower, and dam-related renewable energy infrastructure.

In March 2026, the Union Cabinet approved the Small Hydro Power Development Scheme for implementation from FY 2026–27 to FY 2030–31. The Ministry of New and Renewable Energy subsequently outlined the scale of the opportunity in April 2026.

What is the future of small hydropower in India?

India currently has around 5,171 MW of installed small hydropower capacity against an estimated potential of 21,133.61 MW.

Small hydropower projects require engineering, procurement, civil construction, hydraulic systems, electrical equipment, project management, testing, and commissioning capabilities.

That gap is significant.

Why is small hydropower important for EPC companies?

It suggests that a large share of India’s small hydropower potential remains undeveloped, creating opportunities not only for renewable energy generation but also for engineering, hydraulic infrastructure, dam-based projects, canal systems, water resource management, and EPC execution.

Dam-toe hydropower uses water released from a dam or reservoir to generate electricity using the hydraulic head created by the dam.

For companies involved in water infrastructure and EPC solutions, the renewed policy focus on small hydropower represents an important development in India’s evolving infrastructure landscape.

The Road Ahead

This means the growth of small hydropower could create opportunities across several areas of the engineering and infrastructure sector.

Most importantly, it demonstrates how water infrastructure and energy infrastructure are becoming increasingly interconnected.

What Is Small Hydropower?

It can create opportunities for engineering and EPC companies.

In India, hydropower projects with an installed capacity of up to 25 MW are classified as Small Hydro Power projects.

It can support infrastructure development in remote regions.

These projects generate electricity using flowing or falling water.

It can utilize existing water systems.

The basic principle is relatively straightforward.

It can generate renewable electricity.

Water is directed through infrastructure that creates sufficient flow and hydraulic head. The energy of the moving water drives a turbine, which generates electricity.

Small hydropower fits within this strategy.

However, the infrastructure required to achieve this efficiently can be technically complex.

• More productive
• More sustainable
• More resilient
• More technologically advanced

A small hydropower project may include:

India is increasingly looking for ways to make infrastructure:

• Diversion structures
• Intake systems
• Water channels
• Tunnels
• Penstocks
• Turbines
• Generators
• Powerhouses
• Tailrace systems

The new scheme is important because it highlights a broader direction in infrastructure development.

The exact infrastructure depends on geography, hydrology, available water flow, and project design.

What Does the Small Hydro Power Scheme Mean for India’s Infrastructure Future?

Where Can Small Hydro Projects Be Developed?

Addressing these challenges requires careful engineering and project planning.

One of the most interesting aspects of small hydropower is the variety of infrastructure environments in which projects can be developed.

Projects utilizing dams or canals may require detailed assessments of existing infrastructure.

Run-of-River Projects

Existing Infrastructure Conditions

Run-of-river hydropower projects use the natural flow of rivers to generate electricity.

Hydropower projects must be planned with appropriate consideration for river ecosystems and local environmental conditions.

Unlike large reservoir-based hydropower developments, these projects may require relatively limited water storage.

Environmental Considerations

Water is diverted through an intake structure and transported towards the turbine system.

Projects in mountainous or remote areas can face significant logistical difficulties.

After electricity generation, the water is returned to the river.

Construction Complexity

The viability of these projects depends heavily on:

Engineers must evaluate whether sufficient water will be available for reliable generation.

• River discharge
• Available hydraulic head
• Seasonal flow patterns
• Geological conditions
• Environmental requirements

River flow can vary significantly throughout the year.

Canal-Based Hydropower

Seasonal Water Availability

India has extensive irrigation canal networks.

A location suitable for one type of project may not work for another.

These canals transport enormous volumes of water across agricultural regions.

Every project depends on local hydrology and geography.

Where sufficient water flow and elevation differences exist, hydropower infrastructure can potentially be integrated into canal systems.

Site-Specific Conditions

Canal-based hydropower is particularly interesting from an infrastructure perspective because it can generate renewable electricity from existing water conveyance systems.

Despite its potential, small hydropower development is not without challenges.

Instead of developing an entirely new water source, the project utilizes water already moving through irrigation infrastructure.

What Are the Challenges Facing Small Hydropower Development?

Dam-Toe Hydropower Projects

The combination of civil engineering and digital monitoring is becoming increasingly common across services offered by OmYash Projects and the wider infrastructure industry.

Existing dams can also create opportunities for small hydropower generation.

This allows infrastructure managers to identify potential problems earlier and improve operational performance.

A dam-toe hydropower project generates electricity using water released from a dam or reservoir.

Technologies such as SCADA systems and IoT sensors can provide operators with real-time information.

The hydraulic head created by the dam can be used to operate turbines.

• Water flow
• Turbine performance
• Equipment conditions
• Pressure
• Electricity generation
• Infrastructure safety

This approach can potentially improve the productive use of existing water infrastructure.

Modern systems can monitor:

India has thousands of dams serving irrigation, water supply, flood moderation, and other purposes.

Future hydropower projects will increasingly rely on digital infrastructure.

Integrating appropriate hydropower systems with existing infrastructure could create additional value from these assets.

Why Modern Monitoring Systems Will Matter

Why Existing Water Infrastructure Matters

Infrastructure that can contribute to both objectives could become strategically valuable.

The future of small hydropower is closely connected to the future of India’s water infrastructure.

It also needs better water management.

India has developed extensive networks of:

India needs more electricity.

• Dams
• Reservoirs
• Canals
• Irrigation systems
• Water transmission infrastructure

This intersection between water and energy could become increasingly important.

These assets were primarily created for water management.

It also connects renewable energy development with water infrastructure.

However, some may also offer opportunities for renewable energy generation.

Small hydropower can therefore contribute to a more diversified renewable energy system.

This creates an important shift in infrastructure thinking.

Hydropower can provide more predictable generation where water availability is consistent.

A dam may no longer be viewed only as a water storage asset.

Wind generation depends on wind conditions.

A canal may no longer be viewed only as an irrigation system.

Solar generation depends on sunlight.

Modern infrastructure planning increasingly looks at how individual assets can provide multiple benefits.

However, hydropower provides different characteristics.

For example, a water infrastructure system could potentially support:

India’s renewable energy growth has been dominated by solar and wind power.

• Irrigation
• Drinking water supply
• Industrial water requirements
• Flood management
• Renewable electricity generation

Small Hydropower and India’s Renewable Energy Transition

The major infrastructure projects executed by OmYash Projects demonstrate the scale of engineering coordination required when complex water systems involve multiple infrastructure components.

This makes detailed planning and experienced project execution particularly important.

How Could the Scheme Create Opportunities for the EPC Sector?

• Difficult terrain
• Limited transportation access
• Geological risks
• Extreme weather
• Construction logistics

Small hydropower projects require multidisciplinary execution.

Projects may need to address:

A typical project may involve civil, hydraulic, mechanical, electrical, and environmental engineering.

However, construction in these regions presents significant engineering challenges.

This creates a significant role for EPC companies.

Local hydropower generation can potentially improve energy availability while reducing dependence on long-distance transmission infrastructure.

Engineering

Remote communities and infrastructure facilities may face difficulties accessing reliable electricity networks.

Every hydropower project begins with detailed technical evaluation.

Small hydropower can be particularly valuable in geographically challenging regions.

Engineering teams may need to assess:

The government scheme also places attention on projects in the North Eastern Region, Union Territories of Jammu & Kashmir and Ladakh, and border areas.

• Hydrology
• Water availability
• Hydraulic head
• Geological conditions
• Project layout
• Structural requirements
• Water conveyance systems

Small Hydropower and Remote Infrastructure Development

Poor engineering decisions during the planning stage can affect the long-term performance of the entire project.

India’s existing infrastructure assets may offer opportunities for modernization, efficiency improvements, digital monitoring, and renewable energy generation.

Procurement

However, the broader principle is important.

Small hydro developments require specialized equipment and construction materials.

Technical feasibility depends on several factors.

Procurement may include:

This does not mean every dam can support a hydropower project.

• Turbines
• Generators
• Gates
• Valves
• Pipes
• Electrical systems
• Monitoring equipment

In suitable locations, the modernization of water infrastructure could potentially be evaluated alongside opportunities for energy generation.

Coordinating these requirements is an important part of successful project delivery.

• Structural rehabilitation
• Improved monitoring
• Gate modernization
• Instrumentation
• Safety improvements
• Operational upgrades

Construction

Modernization projects may involve:

Civil construction forms the physical foundation of a hydropower project.

Many dams have been operating for decades.

Depending on the design, construction may involve:

India is also investing in the rehabilitation and modernization of its dam infrastructure.

• Intake structures
• Channels
• Tunnels
• Penstocks
• Powerhouses
• Tailrace systems

Why Dam Modernization and Small Hydropower Could Work Together

This requires coordination between engineering designs and site execution.

As India looks for ways to increase the productivity and efficiency of existing infrastructure, multi-purpose systems could become increasingly important.

An experienced EPC infrastructure company can play an important role in managing complex infrastructure projects involving multiple engineering disciplines.

1. Transport water for agriculture.
2. Generate renewable electricity.

The Importance of Hydraulic Engineering

This could allow irrigation systems to perform two functions:

Hydraulic engineering sits at the centre of small hydropower development.

Instead of constructing an entirely new water system, hydropower technology can potentially be integrated with existing canal infrastructure.

The entire project depends on understanding how water moves through the infrastructure system.

The basic water conveyance infrastructure already exists.

Engineers must evaluate:

The advantage is clear.

• Flow rates
• Water pressure
• Hydraulic head
• Friction losses
• Pipeline dimensions
• Seasonal variations

Where appropriate hydraulic conditions exist, these systems may offer opportunities for electricity generation.

The objective is to move water through the system as efficiently as possible while maximizing energy generation and maintaining infrastructure reliability.

Thousands of kilometres of canals transport water between reservoirs, agricultural regions, and distribution networks.

These engineering principles are closely connected to other areas of water infrastructure.

The country has extensive irrigation infrastructure.

Large water transmission pipelines, lift irrigation projects, pumping systems, dams, and hydropower projects all depend on detailed hydraulic analysis.

Canal-based hydropower deserves particular attention in India.

This is why the growth of small hydropower could also strengthen demand for specialized water infrastructure engineering capabilities.
