Wind power storage plant

Discover how a wind power storage plant works, a renewable energies solution that allows us to progress toward a more sustainable energy system
Wind energy on Global Wind Day

Among the broad range of technological solutions currently offered by renewable energies, wind power is one of the most common. Wind power is a form of energy that uses the force of the wind to generate electricity. It does so via wind turbine generators which, located on land or at sea, transform air streams into energy through a system of blades and other mechanical and electrical components.

Thanks to this form of renewable energy, when the wind blows, a certain amount of kilowatt-hours can be injected into power grids for lighting towns, cities and homes or providing energy to industry. But what happens when the wind that blows is not needed to produce electricity? Well, the energy carried by the wind goes unused.

On the other hand, what happens if we need electricity, but the wind is not blowing hard enough? Until now it was necessary to cover this demand with another form of energy, either renewable or polluting. But today it is already becoming possible to use wind energy even when the wind is not blowing. How? Thanks to electricity storage plants that use batteries, such as the one at ACCIONA’s Barasoain Experimental Wind Power Area in Navarre, Spain.


How does such a storage plant work?

At the innovative plant in Barasoain, some of the electricity produced by a 3 MW wind turbine generator is stored in two kinds of batteries, known as fast-response and slower-response. The fast-response battery is able to supply electricity for 20 minutes, while the slower-response battery supplies less power but over a longer period of time: up to an hour.

In this way, the batteries allow wind energy to be stored when it is not needed, to be used later, when there is demand or the electricity system requires it, although at that precise moment the wind is not active.

Electricity storage systems with batteries are highly promising, due to lowering costs and continuous efficiency improvements. Although still at an initial stage, the technology has demonstrated its usefulness, not only for home use and sparsely-connected grids such as on islands, but also for big applications in developed countries.

This is an innovative technology that allows us to progress toward a more sustainable energy system for everyone. Now find out how such a wind power storage plant functions in the following video.

but is it possible to combine both , solar and windpower jointly to storage batteries. guy



Yes Guy, we do it here in Australia. ( Australia has unveiled a massive new wind, solar and battery project for South Australia, adding to its suite of renewable and storage projects in the country, and taking the total pipeline of renewable and storage projects in the state to more than $20 billion. The Goyder South project is earmarked for Burra, in the state’s mid north, and will comprise up to 1200MW of wind, 600MW of solar, and up to 900MW of battery storage.)

Hey Guy, do a smidgeon of research and you will see there is very little that`s innovative about the concept of storage batteries, undoubtedly battery management is a big issue but that is due to safety and operational requirements of the current technology. Storing electrical energy in large scale plant is what they have been doing for a hundred years, and over that period there has been an increase in kwh versus kg by a factor of approximately x3 so there is still a long way to go before we see affordable, reliable and easily maintainable with long life, storage batteries that are capable of providing long term supply back up for sizeable load requirement. Present systems are fine for the frequency stability and very short duration back up for renewables and of course small communities. When an advertisement spruiks terms like "highly promising" consider this, myriads of break through claims in battery technology lay discarded within the laboratories and universities at which they were developed in embryo form and failed because they could not meet the rigours of practical deployment.

Every lit bit helps. Go for it! In the last election, Labor took the lead on climate change. When asked how much the transfer to renewable energy would cost, all they could say is 'how much will it cost if we don't" Now we are beginning to know. How many lives lost in bushfires? How many houses burnt down? How much will insurance costs increase this year? How many businesses probably destroyed? Etc. Etc. Australia has many advantages when it comes to renewable energy. One disadvantage is that we have a (relatively) sparse population, with the major cities spread far apart. So innovation is also required to improve the efficiency of the transfer of electricity over long distances. Even more important is to make small local communities independent of the grid.

Mike Robertson stick to the subject. Solar and wind power are a welcome step but are presently an eternity away from providing the mains power we need to maintain our standard of living and job security. You are living in another world using the losses from the recent bushfires to justify your argument. Do a bit of bushfire research and you will see that horrific bushfires have been far worse in the past dating back to the 1800's. When Captain Cook sailed up the east coast of Australia he noted in his diary of the smoke pall from fires the Aboriginals had lit . As part of their land management they have been burning from time immemorial. Indeed surely you are aware that a great many of Australia/s trees and shrubs depend upon fire to propagate and survive. Drought is also part and parcel of Australia's landscape. Idiots with matches, controlled burns getting out of control and lightning are some of the main reasons for bushfires.

Thank you for sharing this information. To store solar and wind power is a huge step up. There was once a scientist in Switzerland who wanted to catch/store lightening strikes on the Monte San Salvatore, but unfortunately he died before he reached his goal. Is his scientific project a possibility at all, would you have an idea? I am not a scientist, so I don't know.... ;)
