    Energy storage is going to change the way the grid operates, and make renewables a 24/7 resource.

    The energy density of the lithium-ion battery is about 200 Wh / kg, for example, you want to provide electricity to a city with a population of 1 million, suppose that you need an installed power of 1 GW and at least 8 hours we have a "dead time" when no solar or wind energy. Let's calculate the grid, according to the energy density we need a lithium-ion battery with a weight: (1 000 000 000 / 200) * 8 = 40 000 000 kg it's crazy numbers, even we will have an energy density, like a diesel 5 kWh / kg, we still get crazy values (1 000 000 000 / 5000) * 8 = 1 600 000 kg

    Tech is taking forever to market a decent home use product.
    Does anyone know the best storage source available NOW that's priced to make sense?
    Best I see is the 2400 watt 200ah
    12v Deep Cycle Battery That weighs over 115lbs though, so you need a dolly to go along with it.

    We have heard that line a million times. Lefties needs to stop talking about what they will do and rather what they accomplished. The video is about what they might do and not about what they accomplished.

    A South Australia region power company added Tesla Li-ion battery farm to their grid. The $50 Million investment can act only as a back-up to 30,00 0 homes for a maximum of four hours.

    This tech will NEVER replace on-demand generated power such as coal, LPG, or nuclear.

    Like Musk's other publicity stunts ... it's about generating investment into his non-existent technology schemes.

    Really fucking dumb, fellow.

    How Tesla's big battery is bringing Australia’s gas cartel to heel

    On Sunday 14 January something very unusual happened.

    The Australian Energy Market Operator called – as it often does – for generators in South Australia to provide a modest amount of network services known as FCAS, or frequency control and ancillary services.

    This time, though, the market price did not go into orbit and the credit must go to the newly installed Tesla big battery and the neighbouring Hornsdale windfarm.

    The call for 35MW of FCAS – usually made when there is planned maintenance or a system fault on the interconnector between Victoria and South Australia – has become a running joke in the electricity market, and a costly one for consumers.

    The big gas generators – even though they have 10 times more capacity than is required – have systematically rorted the situation, sometimes charging up to $7m a day for a service that normally comes at one-tenth of the price.

    (You can read reports on how they do it here, here and here, and for a more detailed explanation at the bottom of this story.)

    The difference in January was that there is a new player in the market: Tesla. The company’s big battery, officially known as the Hornsdale Power Reserve, bid into the market to ensure that prices stayed reasonable, as predicted last year.

    Rather than jumping up to prices of around $11,500 and $14,000/MW, the bidding of the Tesla big battery – and, in a major new development, the adjoining Hornsdale windfarm – helped (after an initial spike) to keep them at around $270/MW.

    And they just ordered a 250 Mw/hr battery from Tesla.

    Fellow, anything further to say? You think an order for a 250 MW/hr battery is a publicity stunt. LOL Some people were just born stupid.
