Globally, particularly in developing countries, hydroelectricity production and economic growth occur together with ecosystem/biodiversity conservation in watersheds. There is a relationship between hydroelectricity production and ecosystem/biodiversity conservation in watersheds, centering on the supply and demand for ecosystem services of river water flow regulation and sediment retention. He...

This paper presents a deterministic and a stochastic mathematical model for maximizing the profits obtained by selling electricity produced through a cascade of dams and reservoirs in a spot market. The first model is based on deterministic electricity prices while the other integrates stochasticity through the management of a tree of potential price scenarios. Numerical results based on histor...

Energy supply in Sri Lanka is mainly based on three primary sources, namely hydroelectricity, biomass and petroleum. The supply from each of these sources is such that 11percent is attributable to hydroelectricity, 55 percent to biomass and 34 percent to petroleum oil products. Fuel-wood and other biomass such as coconut residues, paddy husks and sawdust are largely used for domestic cooking ac...

The Swedish electricity supply system benefits strongly from the natural conditions which allow a high share of hydroelectricity. A complete supply is, however, not possible. Up to now, nuclear power is the other workhorse to serve the country with electricity. Thus, electricity production of Sweden is basically CO2-free and Sweden has reached an environmental status which others in Europe plan...

This paper examines the effects of increased intermittency, caused by climate change, on strategic hydroelectric production when wind power is integrated with hydroelectricity. It is shown that increased uncertainty in water inflows caused by climate change raises hydroelectric output and increases the probability of overflow in future periods. The increased variability of wind speeds due to cl...
