Battery firms like Tesla, as well as some utilities, see a mixture of rooftop photovoltaics, home-mounted batteries and electric vehicles as the way of the future, with power being stored locally and new business models emerging to manage customers' energy use remotely.
像特斯拉這樣的電池公司,以及一些公用事業公司,將屋頂太陽能電池、家用電池和電動汽車作為未來的一種混合方式,將電力儲存在本地,這種新的商業模式可以遠程管理客戶的能源使用。
But Mr Galan is sceptical that batteries can last long enough to handle intermittency, or that customers will care enough about distributed energy to make the domestic-battery business compelling.
但Galan先生則質疑電池是否可以持續足夠長的時間來處理間歇性,或者消費者是否會關心國內電池行業中的核心問題——分布式能量。
“I can't imagine saying to my wife that we have a choice between a new fridge and the latest Powerwall battery.”
Galan先生指出“我無法想象告訴我的妻子,我們將在新冰箱和新Powerwall電池之間做出選擇。”

Instead, he believes there is more to be gained by using renewable energy to pump water up to hilltop reservoirs, and letting it flow downhill to produce hydroelectricity when needed.
相反,他認為通過利用再生能源將水抽到山頂水庫會更有利,并在需要時讓它流向山下來產生水電。
Iberdrola has already done this with its successful $1.3bn Cortes La Muela project in Spain, completed in 2013.
2013年Iberdrola公司已經在西班牙花13億成功地做完了Cortes La Muela項目。
It is building a large pumped-hydro storage facility in northern Portugal.
它正在葡萄牙北部建造一個大型抽水蓄能設施。
Mr Galan does not dismiss batteries altogether.
Galan先生并沒有忽略電池。
But he thinks it would be better for utilities to deploy them to regulate the intermittency of electricity supply in substations, rather than putting them in homes.
但他認為對于公共事業來說,調動它們管理變電站供電的間歇性好過于把它們放在家里。
His reservations about fully distributed electricity may be self-serving.
他對全分布式電力的保留可能是自私的。
If users buy batteries to help them cut loose from grids, network operators would have to raise prices to remaining customers, causing a “utility death spiral”.
如果用戶購買電池而不再使用電網,電網運營商就只好對剩余客戶提升價格,從而導致“公用事業死亡螺旋”。
Yet it is probable that centralised electricity will survive, especially in big cities.
然而,集中供電很可能會幸存下來,尤其是在大城市。
And do not write off Iberdrola's predictive powers.
不要低估了Iberdrola的預測能力。
“They could see the future,” says Antonella Bianchessi of Citigroup.
花旗集團Antonella Bianchessi說“他們可以預見未來”。
