"丹麥電動車車主可藉由停車並且將多餘電力回輸至電網每年從電力公司賺取1530美元"
Nissan跟義大利最大的電力公司 Enel SpA 在丹麥做了一項試驗
他們合作展示了電動車的電池是如何有助於平衡(電力)供給與需求
並且提供車主額外的收入
會有這項計劃是因為隨著電動車的增加，電動車所耗費的能源也會急速上升
這會給電力公司帶來額外的壓力
現在正在尋找適合大規模佈署時的商業模式
文章中並沒有說明的很清楚電動車是如何幫助電網供需平衡的
要不要開到特定地點停車或是要在特定地點特定時間停車回輸電力等細節都沒有提到
不過背後的原理不難猜想
就是讓電動車在電力需求尖峰時刻回輸電力，把電動車的電池當成儲能系統用
一但他們把合適的商業模式找出來
說不定大部分的歐洲電動車車主就都能夠享受到這份額外的收入呢

Parked Electric Cars Earn $1,530 From Europe's Power Grids
Electric car owners are earning as much as $1,530 a year just by parking
their vehicle and feeding excess power back into the grid.
Trials in Denmark carried out by Nissan Motor Co. and Italy’s biggest
utility Enel SpA showed how batteries inside electric cars could help
balance supply and demand at times and provide a new revenue stream for
those who own the vehicles.
Technology linking vehicles to the grid marks another challenge for
utilities already struggling to integrate wind and solar power into their
distribution system. As the use of plug-in cars spreads, grid managers
will have to pay closer attention to when motorists draw from the system
and when they can smooth variable flows.
“If you blindingly deploy in the market a massive number of electric
cars without any visibility or control over the way they impact the
electricity grid, you might create new problems,” said Francisco
Carranza, director of energy services at Nissan Europe, in an interview
with Bloomberg New Energy Finance.
While the Tokyo-based automaker has trials with more than 100 cars across
Europe, only those in Denmark are able to earn money by feeding power
back into the grid. There, fleet operators collected about 1,300 euros
($1,530) a year using the two-way charge points, said Carranza.
Restrictions on accessing the market in the U.K. means the company needs
to reach about 150 cars before they can get paid for power sent back to
the grid. That could be achieved by the end of this year, he said.
“It’s feasible,” he said. “It’s just a matter of finding the
appropriate business model to deploy the business wide-scale.’’
Electric car demand globally is expected to soar, putting further
pressure on grid operators to find new ways of balancing demand. Power
consumption from vehicles will grow to 1,800 terawatt-hours in 2040 from
just 6 terawatt-hours now, according to Bloomberg New Energy Finance.
