3. The wind Farm: 5 windmills
turbines
The five windmills turbines, with 2.3 MW
each, have a capacity of 11.5 megawatts with
a rotor of three blades located up 64 meters
high
4. Gorona Del Viento
The Wind-Hydro-Pumped-Power Station
of El Hierro Island
Electricity comes
from wind power
and pumped
hydro storage: the
wind power will
be used to keep
the pumped hydro
reservoirs full,
allowing the
hydro plant to
function as a
baseload and
load-following
5. The wind Farm: 5 wind windmills
turbines
Five windmills on the northeastern
end of the island will power a
pumping station that, when the wind
is blowing, will drive water 2,300 feet
uphill, from a small, 5 million-cubic-
foot (150,000-cu-m) reservoir down
by the shore to a larger, 19 million-
cubic-foot (550,000-cu-m) reservoir
snuggled into one of the island’s
volcanic craters.
6. The wind Farm: 5 wind windmills
turbines
When the wind abates, water
from the top depository will
be released, along 1.8 miles
(3 km) of mostly
camouflaged pipes, into the
bottom one, and the pressure
of that falling water will
drive six hydraulic turbines.
7. The superior deposit ,La Caldera
is located in an inactive volcanic crater, with
380.000m3, 700m high, which is interconnected with a lower
reservoir from the penstocks: two pipes of 3 kilometers long
8. The penstocks for the pumped-storage plant
on El Hierro
carry water to and from the turbines and
pumps.
The capability of the 1.5 MW pumps to regulate the
power consumed through frequency regulators up to
500 kW each or wind turbine-generator frequency
regulation capability.
9. The inferior deposit
has 150.000 cubic meters and is
located near the thermal plant of
Llanos Blancos .
10. The inferior deposit
is lined with a high-density
polyethylene geomembrane for
waterproofing reservoir and the hydro
plant
11. The hydroelectric Subastation
with 4 hydroelectric turbines with speed governors and
flywheels that enable a reaction time of less than 6
seconds.
12. The total power of the
generator groups , with
11.3 mw.
a central pump is
constituted by two
pumps groups 1,500 kW
and 6 kW pumps 500
groups with a total
power of 6 MW.
The Pumping Plant
2x1.500 kw+ 6x 500kw
shares the building
with the control center
operation of the entire
hydro-wind power
plant
Hydroelectric
Subastation,
13. Thermal Power Plant
The Diesel storage tanks in Llanos Blancos only
used when there insn't enough wind or water
produce the demanding energy for the
population. The energy which is not consumed is
sent pumped up to superior deposit
14. The hydro-wind power
plant
It is achieved transform an
intermittent power source into a
controlled and constant electricity
supply, maximizing the use of wind
energy. Thus, the power station
operates as a reserve to support
only during periods of no wind,
minimizing the consumption of
fossil fuels.
