The proliferation of distributed energy resources (DER) around the world has begun to have a significant, and at times controversial, impact on the power and utilities sector. The specific drivers of DER growth?including technology advances, business model innovation, and changing regulations, as well as sustainability and resiliency concerns?vary from region to region. The overarching goal of DER deployments is to integrate these resources effectively in order to make the electricity grid more efficient, resilient, cost-effective, and sustainable. Annual installed capacity across the global DER market is expected to grow from 109.9 GW in 2015 to 335.8 GW in 2024, representing $1.9 trillion in cumulative investment over the next 10 years. This rapid expansion will force a major shift away from the centralized, one-way electrical grid that has remained the norm for the past century. In many markets today, DER deployments are challenging incumbent grid operating models, requiring a more dynamic network with advanced communications and orchestration to ensure stability, efficiency, and equality. Given the diversity of available DER technologies and rapidly declining costs, most countries are expected to see more new DER capacity deployed than centralized generation capacity in the coming decade, especially solar PV, generator sets (gensets), and energy storage. This Navigant Research report provides a quantitative analysis of the global market for DER technologies and assesses the key regional market developments and technology trends. The technologies and solutions covered include distributed solar PV (<1 MW), small and medium wind turbines (<500 kW), microturbines, stationary fuel cells, diesel and natural gas generator sets (<6 MW), distributed energy storage systems,Microgrids, electric vehicle (EV) charging, and demand response. Installed capacity and revenue forecasts for 10 leading countries, as well as their respective regions, extend through 2024. This report also provides a comparison of DER and conventional generation deployments over the next decade.
