Increasing rumblings throughout social media recommend California has so many electrical automobiles that final week’s excessive warmth drove the state’s energy grid to the brink. And so, these arguments contend, it’s ludicrous to mandate further EVs as a result of the grid clearly cannot deal with it.
This commentary is simply plain incorrect and is being lazily supplied up by a number of the similar voices which have shared different debunked EV myths. Batteries didn’t die within the 2021 snow-induced visitors shutdown in Virginia and it didn’t price 10 instances extra to cost when chilly climate triggered the grid to fail in Texas. The upfront environmental impression of manufacturing an EV doesn’t outweigh the advantages of working it over time.
So, is EV charging actually pushing the California energy grid to the brink?
No. It has nothing to do with EV charging.
The state is experiencing excessive warmth, and for a couple of hours within the late afternoon, the electrical energy demand for cooling and cooking exceeds photo voltaic manufacturing. Between 4 and eight p.m., California’s grid operator is asking prospects to show down air con and keep away from EV charging.
Why? At 4 p.m., photo voltaic manufacturing drops off shortly because the solar begins to set. It’s nonetheless extraordinarily sizzling, so individuals want air con. As they get house and begin cooking dinner, there’s further vitality demand that may’t simply be shifted. But it is extremely simple to shift most automobile charging to any of the opposite 20 hours of the day.
Today there are 1 million EVs in California. Let’s say each single one is plugged right into a Level 2 charger on the similar time in the course of the day. This is actually not possible — as there are solely round 71,200 Level 2 chargers in California, however let’s fake. On common, a Level 2 charger attracts 10 kilowatts of energy at a time. That multiplies out to a ten,000-megawatt demand, considerably lower than the 13,000 megawatts of solar energy the state generates on sunny days. So in the course of the day, it is wonderful — it is solely 4 to eight p.m. when there’s a difficulty, and solely in a historic warmth wave.
For extra proof EVs aren’t the issue, contemplate this: Over the previous 4 years, the variety of EVs registered in California has doubled. But peak demand on the grid has solely elevated 5 %, together with all different vitality utilization. Over the identical time, peak photo voltaic manufacturing has elevated from 10,000 megawatts to 13,000 megawatts, a acquire of 30 %.
In a not too long ago printed evaluation by Physics Today, at full penetration, EVs will solely enhance grid demand by 25 %. So whereas this would possibly not be the final time you see misinformation about EVs, it is nonetheless a disgrace the social media ecosystem is on the market amplifying it.
