By the past developments in battery technology, I am sure that there will be a continued decline in prices of the batteries and an increase in the energy density.
Stem CTO: Lithium-Ion Battery Prices Fell 70% in the Last 18 Months
Tesla's battery factory gets a lot of attention. When completed, the so-called Gigafactory will manufacture more lithium-ion batteries each year than were produced globally in 2013.
That will help push prices further downward. But a few other large producers -- LG Chem, Panasonic and Samsung -- are already making batteries at unprecedented scale. There are numerous giga-scale factories producing cells and battery packs for electric cars and stationary applications throughout Asia. And the recent wave of capacity is already impacting pricing in a big way.
According to Larsh Johnson, the chief technology officer of Stem, the company is paying 70 percent less for lithium-ion batteries than it was 18 months ago.
"It’s happening. The capacity is out there," said Johnson in an interview. "The momentum continues."
Stem has installed 68 megawatt-hours of batteries for commercial and industrial applications, mostly to shave demand charges for customers that consume a lot of power in the middle of the day. Johnson said the improvement in pricing is allowing Stem to think beyond traditional demand charge management.
"There are new markets opening up because of what we've seen in battery pricing," he said.
