Well, on one hand, there won’t be as many as the powers that be think, because people won’t be able to afford them. Also, now we’re finding that they will only be able to charge at certain times
California’s electrical grid has an EV problem
California energy officials issued a sobering warning this month, telling residents to brace for potential blackouts as the state’s energy grid faces capacity constraints heading into the summer months.
And since the state has committed to phase out all new gas-powered vehicles by 2035 — well ahead of federal targets — the additional load from electric vehicle (EV) charging could add more strain to the electric grid.
“Let’s say we were to have a substantial number of [electric] vehicles charging at home as everybody dreams,” Ram Rajagopal, an associate professor of Civil and Environmental Engineering at Stanford University, who authored a recent study looking at the strain electric vehicle adoption is expected to place on the power grid, told Yahoo Finance. “Today’s grid may not be able to support it. It all boils down to: Are you charging during the time solar power is on?”
So, you won’t be able to charge up overnight, which would be the most popular time to charge them? Super!
Rajagopal’s team of researchers at Stanford developed a model framework to help utility companies around the world calculate charging patterns to better manage electricity demand. In California, it found that peak charging demand would more than double by 2030 if EV owners opted to charge in the evening at home.
“The use of an electric vehicle is like adding one or two air conditioners to your residence in terms of its energy increase,” Mike Jacobs, Senior Energy Analyst at Union of Concerned Scientists, told Yahoo Finance. “So when the local utility engineer looks at this, he thinks of that air conditioning in the afternoon and the electric vehicle coming home at the same time.”
Jacobs said the transition will mark a dramatic adjustment in behavior. Utility companies and service operators, who have long grown accustomed to “a predictable shape” and schedule in energy usage, will be forced to more actively manage the grid to avoid surges. Likewise, drivers will be forced to adapt to new charging times, with some being asked to plug in at work during the day, while others commit to set hours at night to ensure even distribution of energy capacity.
This sounding funner and funner
A study from Boston Consulting Group estimated utility companies with two to three million customers will need to invest between $1,700 and $5,800 in grid upgrades per EV through 2030 in order to reliably meet the surge in energy demand.
Guess who will pay for that?
