§1What this business is
The unit casts, forges, machines, welds and grinds turbine parts — runners, shafts, casings and bearings — from stainless steel, cast iron, bronze and aluminium alloys, then assembles, pressure-tests and dispatches them to mini hydro projects. Repair, refurbishment and annual maintenance contracts are a second income. This is a medium-scale engineering plant, not a small workshop.
§2Is it right for you?
Who it is for
An engineering firm or experienced promoter with machining know-how and contacts among hydro developers and EPC contractors.
Who it is not for
A first-time founder or anyone without engineering and tendering experience.
Advantages
- Hilly states keep building small hydro plants
- Parts need replacement every 8–10 years, so demand repeats
- Service and AMC work adds steady income
- Nepal and Bhutan are named as export markets
Drawbacks
- Very large investment (₹9.5 crore)
- Long break-even (4–5 years)
- Needs precision machines and skilled engineers
- Orders depend on project approvals and tenders
Skills you need
- Precision machining and welding
- Testing (NDT, pressure, balancing)
- Tendering and EPC relationships
- Project and cash-flow management
Why difficulty 5/5: Crore-scale capital, precision engineering and a 4–5 year break-even.
§3Market
Who buys
- Mini hydro power developers
- EPC contractors
- State renewable energy agencies
- Projects in Nepal and Bhutan
How it sells
- Supply contracts and tenders
- Annual maintenance contracts
- Renewable energy exhibitions
Good to know
- The profile says mini hydro plants replace components every 8–10 years.
- It suggests service hubs in hill districts for quick spares and repairs.

§5Licences & registration
- Udyam registration
- GST registration
- Factory licence
- Pollution consent from the Uttarakhand Pollution Control Board
- Fire NOC
- Supplier/vendor registration with state agencies such as UREDA where needed
§6Schemes & subsidies
Too large for PMEGP or MUDRA. CGTMSE can cover part of the bank loan; the profile also points to MNRE and Uttarakhand state capital subsidies.
§7Money
How the investment is worked out: DUY profile cost ₹9.5 crore (text range ₹8–10 crore): land and building ₹2.5 crore, machinery ₹3.5 crore, working capital ₹2.0 crore, training and marketing ₹0.5 crore, contingency ₹1.0 crore. Finance: own ₹2.5 crore, bank term loan ₹5.0 crore, government subsidy ₹1.5 crore, other sources/JV ₹0.5 crore.
Working capital: ₹2.0 crore, for raw material, salaries and utilities for at least 6–9 months.

§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: EEPC India (Engineering Export Promotion Council)
- Get an IEC and register with EEPC India (RCMC) for engineering exports.
§9Risks — where people fail
- Slow hydro project approvals
- Quality failure in the field
- Long payment cycles from projects
- Competition from established turbine makers
§1030 / 60 / 90-day plan
A general plan that applies to any business. A plan for this business will be added after research.
- Days 1–30: Visit a working mini hydro turbine component manufacturing unit, ask 10 buyers about price and quantity, and get quotations from 3 suppliers.
- Days 31–60: Udyam and the licences you need (Udyam registration, GST registration), a project report (DPR), and the scheme or loan file.
- Days 61–90: Space and machines, trial production, and first deliveries to 10 customers.
