Do Power Companies Fear Plug-In Hybrids?
A car that gets 100 miles per gallon and recharges its trunk full of batteries via a standard electric outlet sounds pretty good to most eco-beaters. One would think the electric companies would be even more excited, just drooling at the chance to power up America’s 270 million cars.
But a Wall Street Journal (registration required) article today says there is an equal amount of fear and lust. In a perfect world, plug-in hybrid owners would recharge their cars at night, helping power companies stabilize the grid and sucking down energy when it’s cheapest. But real world and perfect world might not be friends. They may not even know each other.
If laptop computers are any example, people will charge their cars whenever they can, in fear that they will run out of juice later. That could put enormous strain on the power system, forcing utilities to purchase expensive electricity when demand is highest or even build new power plants, probably coal. Some power companies also fear being hit with new carbon taxes. They might seek tax relief for extra carbon created from powering the plug-ins.
One answer to all this mess… smart meters that charge one price for juicing during the day and a much cheaper rate at night. California utilities expect to have smart meters statewide by 2012. Michigan is also looking into it.
If done right, smart meters could provide efficiency well beyond plug-ins. Homeowners could tell their smart devices to only charge up when the price was right, meanly mostly at night. And air conditioners now running 24/7 might not run at all.
Of course there could be political backlash as well. Poor people might not be able to afford higher prices for air conditioning during the day. The elderly and disabled, who often stay home, could be hit hardest.
