Hydro Projects: Solar & Steel Structure Solutions

Hydro projects sit in remote, hilly, often seismic terrain and need transmission structures to evacuate power. Durable galvanised steelwork is key.

In short

For hydro projects, ENSOL supplies galvanised transmission and substation structures engineered for remote, seismic, humid terrain.

Industry challenges

  • Remote, hilly terrain
  • Higher seismic zones
  • Power evacuation over distance
  • Humid, corrosive conditions

Engineering solutions

  • Transmission towers and structures
  • Seismic-aware design (IS 1893)
  • Galvanising for humid hill environments

Recommended products

Installation approach

  • Design for terrain and seismic zone
  • Fabrication to utility drawings
  • Logistics to remote sites

Applicable standards

  • IS 875 (Part 3) — wind loads
  • IS 1893 — seismic design
  • IS 2062 — structural steel
  • IS 4759 / ISO 1461 — galvanising

Inspection

  • Dimensional check to drawing
  • Coating-thickness verification (NABL)
  • Test certificates and GTP supplied

Maintenance

  • Periodic visual inspection of the coating
  • Scheduled retightening of bolted connections
  • Touch-up of any transport or handling damage

Frequently asked questions

Are structures designed for seismic zones?
Yes — structures are designed to IS 1893 for the site's seismic zone alongside wind loads.
