New report: EVs can make the power grid more efficient and affordable

Plainly, the growing popularity of EVs will have a substantial impact on electric utilities. A new report from nonprofit utility watchdog the Citizens Utility Board (CUB) argues that, with the right public policy, that impact could be a positive one.

The ABCs of EVs: A Guide for Policy Makers and Consumer Advocates“ is intended to help stakeholders, including state regulators and consumer advocates, develop optimal EV-related polices.

While an EV dramatically reduces driving costs, charging requirements could increase a household’s electricity usage by 40 percent, according to CUB. However, managing EVs and related infrastructure as distributed energy resources could result in lower electric rates for all consumers, even those who don’t drive EVs.

“EVs provide an opportunity for tremendous benefit for the electrical system,” said lead author Martin R. Cohen. “But there are also pitfalls if public policy doesn’t keep pace with the new technology.”

“CUB as well as policy makers don’t usually concern themselves with end-use electricity,” said CUB Executive Director David Kolata. “But we argue that the right public policy can use EVs to create a more efficient and affordable power grid.”

    I was told that EV adoption could actually reduce the total usage of electric power in addition to reducing the need for peak power capacity by shifting some of the power generation to the wee hours of the night.

    The reason I was told that EV adoption would reduce the total usage of electricity was that it takes more power to process a gallon of gasoline than what an EV would use to travel the same distance as the IC automobile would use on that gallon of gasoline.

    Anyone have the actual figures?

    EV charging will either make or break the grid as in 20 yrs EV charging will equal all other electric demand.
    And not just because of switching to EVS but because grid demand will shrink radically in 20 yrs as most demand just makes their own for 50-75% less than utility supplied power.
    Thus why EV charging will be so important to manage.
    But as most EVs are parked 23hrs/day and very easy to not just modulate charging but for the EVs, especially with the 200 mile plus ones coming out , generate power into the grid.
    And a major reason for it is to supply the power to fast charge EVs, trucks, in the day, a major load.
    All my EVs, I’ve been driving them 25 yrs now, have always been part of my home power system.
    And my latest modest home is offgrid. Luckily crashed EV batteries are available now greatly lowering batter cost.
