Hydroelectricity Market  remains one of the most established forms of renewable power generation globally. Unlike intermittent sources such as solar and wind, hydropower offers reliable baseload energy and storage capabilities, making it vital to grid stability and energy transition.

1.1 Definition and Key Components

Hydroelectricity is generated by harnessing the kinetic energy of flowing or falling water, typically using dams, reservoirs, or run-of-the-river systems. The primary components include:

• Turbines and generators
• Penstocks
• Dams or diversion structures
• Spillways
• Control systems

1.2 Market Classification

• By Plant Type: Large hydro, small hydro, pumped-storage
• By Capacity: Below 1 MW, 1–10 MW, Above 10 MW
• By End Use: Residential, Industrial, Utility
