Energy storage costs could decrease up to 70% in the next 15 years, according to a report called E-Storage: Shifting from Cost to Value, by Paul Gardner from DNV GL and other authors. PriceWaterhouseCoopers also contributed cost analysis, along with inputs from 23 experts.
Another key point from the report is that the authors believe the true cost of energy storage hasn’t been documented very accurately, because it doesn’t factor in revenue benefits. They also say the metric that is generally used, the levelized cost of energy, is actually hampering the progress of energy storage.
