The business case for nanogrids echoes many of the same arguments used on behalf of microgrids. These smaller, modular, and flexible distribution networks are the antithesis of the bigger-is-better economies of scale thinking that has guided energy resource planning over much of the past century. Nanogrids take the concept of a bottom-up energy paradigm to extreme heights. In some cases, the networks articulate a business case even more radical than that for a microgrid; in other cases, nanogrids peacefully coexist with the status quo. Growing utility opposition globally to traditional solar PV support mechanisms such as net metering and feed-in tariffs (FITs) only helps to build the business case for solar PV plus energy storage nanogrids. Extracting the greatest value from solar PV in the absence of subsidy will require linking this variable distributed generation (DG) to a battery. As such, pairing solar PV with energy storage in a distributed fashion will soon emerge as the most economical way to successfully incorporate distributed energy resources into today?s market landscape. According to Navigant Research, global solar PV plus energy storage nanogrid revenue is expected to grow from $1.2 billion in 2015 to $23.1 billion in 2024. This Navigant Research report analyzes the global market for solar PV plus energy storage nanogrids, with a focus on distributed solar PV installations in behind-the-meter building-level applications for residential and commercial customers. The study provides an analysis of the market issues, including cost trends, business cases, and synergies, associated with nanogrids, solar PV, and energy storage systems. Global market forecasts for capacity and revenue, segmented by application and region, extend through 2024. The report also examines the key technologies related to solar PV plus energy storage nanogrids, as well as the competitive landscape.
