Solar Power Station that generates electricity at NIGHT

It looks like a giant art project. But this symmetrical, circular pattern of mirrored panels 
is the world's first solar power station that generates electricity at night.

.
The Gemasolar Power Plant near Seville in southern Spain consists of an incredible 2,650 panels
spread across 185 hectares of rural land.
The mirrors - known as heliostats - focus 95 per cent of the sun's radiation onto a giant receiver
at the centre of the plant.


.
Heat of up to 900C is used to warm molten salt tanks, which create steam to power the £260million
station's turbines.

.
But, unlike all other solar power stations, the heat stored in these tanks can be released for up to
15 hours overnight, or during periods without sunlight.

.
The regular sunshine in southern Spain means the facility can therefore operate through most nights,
guaranteeing electrical production for a minimum of 270 days per year, up to three times more than 
other renewable energies.

.
The project, a joint venture between Abu Dhabu energy company Masdar and Spanish engineering firm 
SENER called Torresol Energy, took two years to construct at a cost of £260million.
It is expected to produce 110 GWh/year - enough to power 25,000 homes in the Andalucia region.

.

.
Miguel Domingo, spokesman for SENER, said: 'The on-schedule and on-budget completion of the construction
and commissioning of the Gemasolar plant is a milestone for SENER.

.
'Currently, SENER is the only company in the world that has developed and built a commercial plant with 
central tower molten salt receiver technology that has already started operation.'

.
Enrique Sendagorta, the chairman of Torresol Energy, added: 'The standardisation of this new technology
will mean a real reduction in the investment costs for solar plants.

.
'The commercial operation of this plant will lead the way for other central tower plants with molten salt
receiver technology, an efficient system that improves the dispatchability of electric power from renewable sources.'

One year of hopes, no more than ninety seconds to make the dream come true. Ten jockeys, dressed in the representative colors of their contrade,
riding bareback on magnificent horses, while citizens on the bleachers scream with pride. They circle the Piazza del Campo three times to win the Palio.
