The era of battery-based energy storage is upon us

摘要

In a series of tweets in early March, Tesla founder, CEO and Chairman Elon Musk made a dramatic offer to help address the issues bedeviling South Australia's electricity grid: he offered to install 100MW of battery storage within 100 days — or the system would be free. This led to talks between Musk and South Australia's Premier, and with Australia's Prime Minister Malcolm Turnbull. At the time of writing, it was unclear whether the offer would be taken up, and there are serious questions as to whether such a system would be an appropriate solution to the blackouts plaguing the Australian state. But the attention that Musk's offer generated is testament to the increasingly important role that battery storage, at scale, is playing in modern electricity systems.
