The cost of building a dam for hydroelectricity can vary greatly depending on the location and size of the project. A large number of factors contribute to the cost of building a dam, including:
Location: The farther away from your source of water and power, the more expensive it will be to build a dam.
Size: The larger your dam, the more expensive it will be to build. This is because you will have to construct a larger spillway or outlet tunnel and pay for more concrete.
Engineering requirements: If you are required to construct an extra-high dam or an earth-fill dam, the cost will increase substantially.
Construction materials: The type of material used in constructing your dam can affect its cost significantly. For example, if you choose to use clay instead of concrete in building your drainage system, then this will increase the cost by around 20%.
Cost to build a dam for hydroelectricity
The cost to build a hydroelectric dam depends on the size of the project. Smaller projects can cost as little as $10 million, while larger projects can cost hundreds of millions of dollars or more.
The total cost will also depend on the type of dam being built and where it will be located. For example, a reservoir dam costs more than an earthfill dam because it requires more concrete and other materials.
How much does it cost to build a small dam?
A small hydropower project might require only one turbine that produces 100 kW of power. The total construction costs for this type of project could range from $7 million to $20 million depending on the location and size of the reservoir created by the dam.

how much does it cost to build a small dam
A small dam is a small structure that produces hydroelectric power. It usually has a height of less than 30 feet (10 meters). The most common form of small dam is the weir, which is an embankment across a stream or river that creates a pond of water. When the water flows over the crest of the weir, it generates power through the force of gravity. how much does it cost to build a small dam
A gravity dam relies on the force of gravity for its stability; therefore, its shape must be strong enough to hold back water without being crushed by its own weight. Gravity dams are typically made of concrete or stone masonry and are often lined with riprap (large stones) to make them more stable.

According to an article published by Hydro Review, there are about 2 million small dams worldwide with capacities ranging from 1 kW to 100 kW.
