Microgrids vary immensely in size, resource mix, vendor composition, and application.As a result, estimating the related operations and maintenance (O and M) revenue opportunities requires careful consideration.A diverse set of opportunities present themselves in this aspect of the microgrid ecosystem, though clarity on the extent and nature of how best to capture these revenue streams remains clouded.This report examines the types of O and M revenue opportunities that are both the most lucrative and available to the widest array of potential market participants.The revenue opportunities for fixed cost O&M are typically significantly greater than those for variable O and M--even for highly utilized generation assets with frequent asset dispatch that incur relatively high variable O&M costs.Thus, this report is focused on fixed cost O&M microgrid revenue opportunities.Today, by virtue of having the largest installed base of microgrids, North America leads the world in fixed O&M opportunities, followed by Asia Pacific. According to Navigant Research, global fixed O&M revenue is expected to grow from $828.4 million in 2017 to just over $4.0 billion in 2026.This Navigant Research report analyzes the global market potential for the provision of O&M services for key microgrid enabling technologies (MET), major microgrid market segments, major regions, and 10 selected countries. The study provides an analysis of the O&M revenue opportunity drivers in the microgrid market and the key technology trends affecting these opportunities. Global market forecasts, broken out by segment, MET, and region, extend through 2026.
