Several energy storage projects that were under construction early in the year reached commercial operation in 3Q 2016. New projects are being announced on a routine basis, 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 new geographic markets continuing to open up. According to Navigant Research, lithium ion (Li-ion) batteries remain the leading form of storage for new projects worldwide, accounting for 83.0% of newly announced ESS capacity storage through 3Q 2016 (excluding pumped hydro storage). Li-ion batteries are the most popular technology for the growing distributed energy storage system (DESS) and BTM market segments. Also notable within the market is the increase in announced projects utilizing flow batteries and hybrid battery systems. Hybrid systems are advantageous in that they can provide multiple services to the grid based on dynamic conditions and specific requirements. While market activity has picked up in a number of regions during 2016, North America remains the largest market for newly announced ESSs. An estimated 1,997.3 MW of new ESSs have been announced worldwide in 2016 so far, with approximately 15.8% coming from North America. This Navigant Research report provides a comprehensive resource of global energy storage projects. The Tracker includes a database of 1,201 projects (encompassing roughly 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.
