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.
The levelised cost of electricity (LCOE) for hydropower refurbishments and upgrades ranges from as low as USD 0.01/kWh for additional capacity at an existing hydropower project to around USD 0.05/kWh for a more expensive upgrade project assuming a 10% cost of capital.
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).
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.
Pumped storage hydropower projects are a natural fit in an energy market with high penetration of renewable energy as they help to maximise the use of the renewables that are subject to the vagaries of the weather. Pumped storage provides a load when the there is a surplus of supply and storage that can be recovered later.
The average cost for European countries ranges from USD 0.04 to USD 0.18/ kWh (Figure 6.1). A brief review of the LCOE range for hydropower in countries with the largest installed capacity of hydropower today is revealing. At the best sites, the LCOE of hydro is very competitive and among the lowest cost generation options available.
