Costs have fallen so rapidly for battery storage capacity that within two years the technology will be cheap enough for households with existing rooftop solar systems. That is according to a new report published today by the Renewable Energy Agency (REA) and consultancy KPMG, which found that by around 2017 the cost of lithium ion storage technology will have fallen low enough for early adopter households and businesses to retrofit it onto existing energy generation systems.

In November 2015, financial advisory firm Lazard released its first-ever Levelized Cost of Storage Analysis (LCOS). Well known for its Levelized Cost of Energy Analysis (LCOE) analysis—now out in version 9.0—Lazard publishing an analysis of storage is a major sign that it considers battery energy storage a critical technology that’s here to stay. But a closer look at Lazard’s LCOS shows something RMI’s October 2015 Economics of Battery Energy Storage report noted: a) battery economics are usually evaluated on the basis of single-use cases, b) stacking multiple uses can greatly enhance battery economics, and c) evaluating those economics gets difficult quickly. It’s the use cases and stacked value streams—in addition to per-kWh cell cost declines—that offer tremendous opportunity.
