These climate scammers and promoters of wind turbines are full of hot air!
Claims that mega-batteries will fix wind and solar’s natural intermittency problem turn out to be mega-myths.
First, lithium-ion batteries of the kind pitched by Tesla (see above) – like every kind of battery – do not generate a single watt of power and are net consumers of electricity during their charge/discharge phase.
Second, they are insanely expensive – relative to the trivial amounts of power they are capable of storing and releasing.
Third, they are not designed to operate at grid-scale; at their best, they are used for balancing frequency and voltage disturbances caused largely by, you guessed it, the chaotic delivery of wind and solar.
South Australia’s $150 million big-battery at Hornsdale (pictured above) is exclusively used for that purpose (ie frequency control).
When wind power output collapses, it’s used to add power briefly to the grid to allow time for a nearby 200MW open cycle gas turbine plant
