I think it is fair to say that residential scale storage, despite not yet having a strong ROI, is really starting to gain traction. For the home owner clearly we are still at the 'early adopter' stage, much like when I started selling PV in 2008, It was only the committed and the affluent, but they bought then, and they are buying now. PV on the roof, maybe an EV on the drive, and some storage in the house. This report though shows how utilities as well as cost reductions will drive massive role out of residential scale storage. And some of our clients are leading the way.
There are numerous factors driving the residential energy storage market worldwide, including the growing residential solar PV industry, falling system costs, rising electricity prices, a push to improve resiliency, increasing awareness of home energy consumption, and the desire to use clean and locally generated electricity. Leading RESS markets around the world are driven by these factors, as well as by government subsidies, incentives, and evolving utility rate structures. Currently, the residential energy storage market is highly concentrated in select leading markets. In 2016, Australia, Germany, Japan, and the United States are expected to account for 81.4% of the global market. According to Navigant Research, global annual deployments of RESSs are expected to increase from 94.9 MW in 2016 to 3,773.3 MW in 2025.
