But the large pulses of
intermittent power they generate are not easy to integrate into the grid.
Put another away — the nearly useless
intermittent power generated by wind and solar has been replaced by two power deals with Quebec.
Not exact matches
Therefore,
power generators and grid operators need back - up capacity that can fill the generation gap that results when these
intermittent sources are unavailable and that also can be scaled back when
intermittent sources are
generating power.
EVs will recharge when renewable energy sources are
generating power and wholesale prices are low, thus helping the system adapt to
intermittent solar and wind.
If you want to get polluting sources of electricity out of your
generating portfolio, it helps to have a lot of hydroelectric
power: It's cheap and it's less
intermittent than the wind and the sun.
One of the big issues for renewables are the technical limits of
intermittent power in the grid — that is,
power that can not be dispatched at will and is not
generated in a continuous fashion.
The much lower
power -
generating capabilities of renewables due to their
intermittent output (the Sun has to shine and the wind must blow) has meant that reliable backup capacity — fossil fuels or nuclear — must remain on the grid.
Neglecting to point out that because
intermittent renewables struggle to
generate power over a third of the time we will likely have to over-build renewable capacity and add massive amounts of energy storage biases the renewable argument.
This isn't something new (Norway does something similar with its hydro
power), but as more and more
power is
generated from
intermittent sources, we'll probably see more of it.
