Why in News
The Union Cabinet chaired by Prime Minister Narendra Modi approved the Small Hydro Power (SHP) Development Scheme for FY 2026-27 to FY 2030-31 with an outlay of Rs 2,584.60 crore and a target of installing approximately 1,500 MW of small hydropower capacity. The scheme prioritises hilly and Northeastern states, where small rivers and streams offer untapped renewable energy potential.
Key Features of the Scheme
| Parameter | Details |
|---|---|
| Outlay | Rs 2,584.60 crore |
| Target capacity | ~1,500 MW |
| Period | FY 2026-27 to FY 2030-31 (5 years) |
| Project size | 1 MW to 25 MW capacity |
| Implementing agency | Ministry of New and Renewable Energy (MNRE) |
| Beneficiary | State governments, public sector undertakings, private developers |
Central Financial Assistance (CFA) Pattern
| Region | CFA Rate | Maximum per Project |
|---|---|---|
| NE States + border districts | Rs 3.6 crore/MW or 30% of cost | Rs 30 crore |
| Other states | Rs 2.4 crore/MW or 20% of cost | Rs 20 crore |
The differential CFA reflects the higher construction cost in remote, hilly terrain and aligns with the broader policy of giving NE states preferential treatment under the Act East Policy.
What is Small Hydro Power?
Small Hydro Power refers to hydroelectric projects with installed capacity up to 25 MW, governed by the Ministry of New and Renewable Energy (MNRE). Larger projects (above 25 MW) come under the Ministry of Power.
| Category | Capacity |
|---|---|
| Pico hydro | < 5 kW |
| Micro hydro | 5 - 100 kW |
| Mini hydro | 100 kW - 2 MW |
| Small hydro | 2 MW - 25 MW |
| Medium/Large hydro | > 25 MW (under Ministry of Power) |
Why SHP Matters
- Decentralised generation: No need for massive dams or transmission infrastructure
- Low ecological footprint: Run-of-the-river designs avoid large reservoirs
- Reliable baseload: Unlike solar/wind, hydro can provide round-the-clock power
- Rural electrification: Ideal for remote villages off the central grid
India’s SHP Status
| Parameter | Data |
|---|---|
| Installed SHP capacity (as of 2025) | ~5,000 MW |
| Identified potential | ~21,000 MW |
| Untapped potential | ~16,000 MW |
| Top SHP states | Karnataka, Himachal Pradesh, Andhra Pradesh, Kerala, Uttarakhand |
| Number of SHP sites identified | 7,135 across 22 states/UTs |
The scheme aims to reduce the gap between installed capacity (5,000 MW) and identified potential (21,000 MW) by adding 1,500 MW over 5 years.
SHP in India’s Renewable Energy Mix
India’s renewable energy targets:
- 500 GW non-fossil capacity by 2030 (Panchamrit commitment, COP26 Glasgow)
- 50% of installed capacity from non-fossil sources by 2030
- Net zero by 2070
Current renewable capacity (~190 GW as of early 2026):
| Source | Capacity |
|---|---|
| Solar | ~85 GW |
| Wind | ~46 GW |
| Large Hydro | ~47 GW |
| Small Hydro | ~5 GW |
| Biomass | ~10 GW |
SHP is a small but strategically important component — ideal for hilly states where solar/wind potential is limited but rivers are abundant.
Why NE States Get Priority?
The Northeastern region has massive hydro potential (~63 GW total identified hydro potential across all NE states) but limited capacity addition due to:
- Difficult terrain
- High construction costs
- Land acquisition challenges
- Insurgency-related delays (now largely resolved)
The 30% CFA (vs 20% for other states) addresses the cost premium of NE construction. This aligns with the Act East Policy and the Centre’s broader Northeast development push.
Environmental and Social Considerations
Advantages:
- Run-of-the-river design avoids large reservoirs
- Minimal land submergence
- No relocation of large populations
Challenges:
- Cumulative impact of multiple SHPs on river ecology
- Fish migration disruption
- Sediment flow alteration
- Conflict with riparian communities
The Sustainable Sand Mining Management Guidelines (2016) and Environmental Impact Assessment (EIA) Notification 2006 apply to SHP projects above certain thresholds.

Facts Corner
- The Ministry of New and Renewable Energy (MNRE) was formerly the Ministry of Non-Conventional Energy Sources, renamed in 2006 to reflect the focus on “new” technologies (solar, wind) alongside traditional renewables (small hydro).
- India’s first hydroelectric project was the Sidrapong Hydroelectric Power Station (130 kW) built in Darjeeling in 1897 — making India one of the earliest adopters of hydroelectric power in Asia.
- Karnataka has the largest installed SHP capacity in India (~1,200 MW), followed by Himachal Pradesh and Andhra Pradesh.
- The Bhakra-Nangal project (1948-1963) and Hirakud Dam (1948-1957) were India’s first large-scale hydroelectric projects — built in the Nehru era as “temples of modern India.”
- Pumped storage hydropower is a related concept — water is pumped uphill during off-peak hours and released to generate power during peak demand. India is rapidly expanding pumped storage as a complement to solar/wind.
- The PM-KUSUM scheme is the parallel solar equivalent of SHP — supporting solar pumps and decentralised solar generation in agriculture.
