The distributed energy storage industry has continued to mature substantially over the past several years, both in terms of storage products and the business models employed by vendors. The focus of this report is on distributed energy storage systems (DESSs) installed behind the meter (BTM) for either commercial and industrial (C&I) or residential buildings. New products recently launched in the market are much more fully integrated and modular plug-and-play systems designed for fast and low cost installation and integration with existing building technologies. Numerous vendors offer well-designed, visually appealing products marketed toward eco-conscious homeowners and businesses. Perhaps the most significant advancement in this industry has been the increasingly sophisticated software and control platforms for DESSs that allow systems to be virtually aggregated to provide grid services and participate in wholesale markets. The new platforms available from leading vendors have made the roles of systems integrator and operator critical. System providers are capitalizing on this new opportunity by maintaining ownership of DESSs through shared savings and lease models. While the distributed energy storage industry has seen significant growth during the past 2 years, the market remains highly concentrated in select areas around the world. According to Navigant Research, global annual DESS capacity additions are expected to grow from 683.9 MW in 2017 to 19,699.7 MW by 2026. This Navigant Research report analyzes the global market for newly installed DESSs for both C&I and residential customers. The study provides an analysis of the regional market issues, including recent trends, market dynamics, drivers, and barriers, associated with the distributed energy storage industry. Global market forecasts for capacity and revenue, broken out by segment, country, and building type, extend through 2026. The report also examines the DESS markets for the top 10 countries and the business case for customers to deploy distributed energy storage.
