"Oncor Electric Delivery, owner of the largest power-line network in Texas, wants to spend more than $2 billion on batteries to solve the problem of fluctuating output from wind and solar.

In the next seven or eight years, the price of batteries used for storage may fall by about half, to $230 a kilowatt-hour of generating capacity, said Sofia Savvantidou, an analyst at Citigroup Inc. in London.

Tesla has announced plans to build a “gigafactory” in Nevada that would produce batteries that can supply power to cars and store electricity for utilities. The company has said it plans to cut the per kilowatt-hour cost of its batteries by more than 30 percent."
