Do hydropower plants cost a lot?

The levelised cost of electricity for hydropower plants spans a wide range, depending on the project, but under good conditions hydropower projects can be very competitive. Existing hydropower plants are some of the least expensive sources of power generation today (IEA, 2010b).

Does hydropower cost more than other renewable technologies?

The large civil works required for hydropower mean that the cost of materials and labour plays a larger role in overall costs than for some other renewable technologies. There is significantly less variation in the electro-mechanical costs.

Will a hydropower reduce costs in the future?

H ydropower is a mature, commercially proven technology and there is little scope for significant cost reductions in the short-to-medium term. Technological innovation could lower the costs in the future, although this will mainly be driven by the development of more eficient, lower cost techniques in civil engineering and works.

How much does a hydropower project cost?

Large hydropower projects will typically average around 2% to 2.5%. Small hydropower projects don’t have the same economies of scale and can have O&M costs of between 1% and 6%, or in some cases even higher. 3. The cost of electricity generated by hydropower is generally low although the costs are very site-specific.

How does a hydro power plant affect the cost of a generator?

This will be influenced to some extent by the hydro resource but is also a trade-of between guaranteeing availability (if there is only one generator and it is ofline, then generation drops to zero) and the capital costs (smaller units can have higher costs per kW).

Why is hydropower a good energy source?

As an adjustable and energy source, hydropower can firm wind power, balance wind deviation by providing large spare capacity and flexibility, reduce the differences between the forecasted and actual wind generation, and smooth wind power output [3, 19].
