Britain: National Power Grid to tap electric cars when in need of extra juice

Electric car owners will be called on to help Britain avoid an energy crunch as suppliers prepare tariffs allowing them to draw power from parked vehicles at times of low supply or high demand.

Cars which are charging on driveways are to be plugged into a system responsible for balancing the National Grid for the first time, in an experiment aimed at easing the burden on the country's creaking energy infrastructure.

It will lay the groundwork for a national rollout of the technology if successful, paving the way for millions of electric cars to act as a giant battery so that power supply is stable at times of low wind speeds after the transition to green energy.

In the trial, which will begin at some point from April to June, car owners will agree to allow the grid to draw power from their vehicles and release it as and when required. They will be paid for energy which the grid drains off.

According to the comments, the planned rebate will be 15/p per kwh. The problem is that the car owners are charged 19/p per kwh by the power grid. 

WSJ: The Achilles Heel of the Electric Car Revolution- Poor Charging Infrastructure

Bradley Wilkinson is the owner of a 2017 Chevrolet Bolt, and the kind of electric-vehicle diehard who knows how to squeeze every last mile of range out of his vehicle.

Even so, during his most recent road trip, from Tampa, Fla., back home to Fort Carson, Colo., he spent about 58 hours on the road. In a gasoline-powered vehicle, on average, the 1,900-mile journey would take about 30. His relatively sluggish pace was due to his need to regularly power up the Bolt’s battery at a “fast” charger—so called because they’re many times faster than typical home chargers.

Less experienced EV owners report far bigger inconveniences than Mr. Wilkinson’s. Those include: too few charging stations, too much demand at the stations that are available, broken chargers, confusing payment systems, exorbitant electricity rates, and uncertainty over how long their cars need to charge.

While EVs can be powered up at home, industry analysts and academics believe that a fast-charging infrastructure is essential to getting beyond their current limited adoption. This next wave of slightly-less-early adopters is critical to a global automotive industry betting heavily on battery power.

Yet so far, only one carmaker has offered a reassuring pitch about conveniently and reliably recharging on the go: Tesla. And Tesla’s fast-charging technology doesn’t work on non-Tesla cars.

Building the requisite charging infrastructure for the rest of the EV universe will be expensive. The Biden administration has proposed building a network of 500,000 chargers in the next five years, which would cost billions. The fact that many believe such a government investment is required shows just how little faith many industry insiders have in the ability of private enterprise to solve this problem. One issue: Building out the nation’s charging infrastructure might not be profitable.
