Tracking progress 2020
For the first time in nearly a decade, annual installations of energy storage technologies fell year-on-year in 2019. Grid-scale storage installations dropped 20%, while residential battery installations doubled, consolidating a shift towards behind-the-meter storage. Continued uncertainty in 2018’s key growth market, Korea, and sluggish activity in Europe and the United States underpinned a lacklustre year for storage. Events in 2019 highlighted how fragile growth in these technologies remains, as they continue to depend heavily on policy intervention through direct support or market creation. Storage needs to return to double-digit growth figures to stay on track with the SDS pathway.
