How much does building a hydro power plant cost?

The cost of building a hydropower plant can vary significantly based on factors such as location, plant size, and design complexity. On average, costs can range from $1,000 to $5,000 per installed kilowatt of capacity. Smaller projects may be less expensive on a per-kilowatt basis compared to large-scale plants, which can involve higher infrastructure and environmental considerations. Overall, total project costs can range from millions to billions of dollars depending on these variables.
