Energy storage is shifting from being considered a nonessential but desirable addition to renewable energy projects into a standalone solution that provides customers and system owners significant value.The traditional emerging markets in the energy storage sector have become prime targets for both new and established industry participants. New projects are being announced on a weekly basis in 2017, and the global energy storage industry is continuing to explore different business cases that make energy storage systems (ESSs) profitable.Innovative applications like renewables integration and behind-the-meter (BTM) systems are becoming economically attractive, resulting in the continued emergence of new geographic markets.Navigant Research believes that improvements in performance in energy storage technologies, developing regional regulatory and market drivers, declining capital costs, and new business models are poised to make energy storage a growing and viable part of the electricity grid. Several key factors are expected to drive the global need for increased energy storage deployments. For example, the development of new distributed, intermittent, and variable generation sources (such as solar PV and wind) that are connected to global power grids will require increased load balancing against demand.Overall, the global energy storage industry is poised to continue growing quickly over the next several years.This Navigant Research report provides a comprehensive resource of global energy storage projects.The Tracker includes a database of 1,420 projects (encompassing at least 43,083 individual systems) and tracks the country, region, market segment, capacity, status, technology vendor, systems integrator, applications, funding, investment, and key milestones of each project. In addition, the report includes an analysis of the technology choice within each major region for energy storage, analysis of the leading regions for energy storage capacity and projects, and market share analysis for technology vendors for deployed projects and projects in the pipeline.
