Power prices are negative 200 million times/year in US and rapidly growing! European grid has more renewables, we can expect it to be negative more frequently.

Power prices are negative 200 million times/year in US and rapidly growing! European grid has more renewables, we can expect it to be negative more frequently.
Right now, negative prices shut down production, wasting all the free production, called curtailment. Instead, EV owners can charge and be paid for charging. In fact, EV owners can get paid twice, once for charging and again for supplying power back to the grid as part of a virtual power plant. In a pilot this year, participants in VPP with their powerwalls made $150/day. It is entirely possible to do this with EVs.
And, very few needs 100% charge/range. 52% of all trips, including all modes of transportation, were less than three miles, with 28% of trips less than one mile. Just 2% of all trips were greater than 50 miles.[3]. You can set a range, keep my car charged between 60 - 90% at all times, give me money both for charging and supplying power back to the grid! I'm sure there will be some people who'd be interested in free money.

[2]Wholesale prices went negative about 200 million times across the seven US grids in 2021, more than twice as often as five years earlier:

- adolph 3y ago> Power prices are negative 200 million times/year in US and rapidly growing! European grid has more renewables, we can expect it to be negative more frequently. Given 31,536,000 seconds in a year, a more descriptive aggregate statistic might be how much of total capacity was at a negative billing rate.
