CT: Furthermore, table 6.1 presents a typical one-day period of operation of the combined wind-hydro power station in the area of Biannos. The wind speed distributions during a year and the monthly demand of Biannos –area have been provided by the Wind Energy Laboratory and PPC respectively. The wind energy supplied to the consumers in order to cover the demand is taking into account the number and the type of wind turbines and also the wind speed. When there is excessive amount of wind energy, this is diverted to the water pump station (for pumping), which is carrying water from a lower tank to a higher level and stores it. When the wind farm doesn’t cover the consumer energy demands sufficiently, the hydro system produces energy utilizing the water stored in the upper reservoir (requirement power from water turbine). Finally the volume in the upper reservoir, the energy shortage due to the empty reservoir and the total losses of the power system are evaluated.

N: 1. wind-hydro: From “wind” (Middle English, from Old English; akin to Old High German wint wind, Latin ventus, Greek aēnai to blow, Sanskrit vāti it blows; first known use: before 12th century) and “hydro” (short for hydropower, hydroelectric power; first known use: 1916).
power station (first known use: 1901): Used as synonym of power plant (first known use: 1890).
2. A wind-hydro system generates electric energy combining wind turbines and pumped storage. The combination has been the subject of long-term discussion, and an experimental plant, which also tested wind turbines, was implemented by Nova Scotia Power at its Wreck Cove hydro electric power site in the late 1970s, but was decommissioned within ten years. Since, no other system has been implemented at a single location as of late 2010.[3]
Wind-hydro stations dedicate all, or a significant portion, of their wind power resources to pumping water into pumped storage reservoirs. These reservoirs are an implementation of grid energy storage.
3. The Wind-Hydro-Pumped Station of El Hierro has been successfully inaugurated last June 27th, with the participation of politicians and technicians involved in the project. The event made the headline in the press and was a momentous day in the island’ s history after three decades of gestation of an innovative project using renewable self-sufficient energy.
The central of El Hierro opened today with the aim of turning the Canary Island as the first island capable of supplying its own electricity with its own resources.
The system consists of two water tanks, a wind farm of 11.3 MW with five Enercon turbines, a hydroelectric plant and a pumping, it is managed by the company Gorona Wind El Hierro, and participating as partners, the Cabildo de El Hierro (60%), Endesa (30%) and ITC (Instituto Tecnológico de Canarias, 10%)
4. What is Wind and Hydropower Integration?
● Combining wind and hydropower resources to the mutual benefit of each: ● Wind benefits: ancillary services, energy storage ● Hydro benefits ● Electricity customer with market exposure: long-term, low- cost wind ● Hydro facility: economic benefit, water storage, EIS compliance, relicensing… case specific ● System benefits: better utilization of transmission and generation assets (hydro 35% to 50% capacity factor).
