With the availability of more decentralized energy resources (DERs), such as rooftop solar panels and home batteries, the need for smart grids has grown rapidly. These grids rely on advanced technologies to balance energy supply and demand. Energy storage helps enhance grid reliability by providing frequency regulation that can charge and discharge rapidly to help balance frequency in the grid. It also enables batteries to maintain voltage levels within the required range to avoid damaging the equipment. ESaaS is increasingly becoming a preferred model for customers because it provides grid operators and utilities with on-demand access to storage capacity without requiring significant upfront investments.

Energy storage-as-a-service enables users to pay for storage services rather than owning and maintaining the technology. This helps consumers avoid costs associated with purchasing, installing, and maintaining energy storage systems. Businesses and consumers can access the latest advancements in storage technologies without needing to manage them independently. The rapidly growing electric vehicle (EV) industry presents another promising opportunity for companies to launch innovative solutions. ESaaS can be deployed at EV charging stations to store energy during off-peak hours when electricity is cheaper and discharge during peak hours to avoid stressing the grid. Moreover, EVs equipped with bidirectional charging capabilities can return power to the grid, with ESaaS solutions helping manage these flows to balance demand and supply efficiently.

The need for organizations globally to adhere to environmental norms and achieve corporate sustainability goals has further driven the deployment of energy storage solutions to reduce carbon footprints. Storing and using clean energy when available reduces reliance on fossil fuel-based backup generation, which helps achieve carbon reduction goals. These factors are expected to enhance the appeal of global energy storage as a service industry in the coming years. ESaaS is a relatively new model, with a limited number of companies offering these services globally. Most of these organizations operate in the regional and local markets, thus presenting a significant opportunity to boost their demand in untapped markets and remote areas with a general lack of power supply.

ESaaS providers can automate this process, ensuring customers avoid expensive peak-hour electricity costs. This model witnesses a significant demand for its role in effective customer energy and power management. It is utilized as backup power to ensure reliability when the customer leverages solar or other renewable energy sources.

The ancillary services segment is anticipated to expand at the highest CAGR during the forecast period in the global market, owing to the widespread adoption of battery storage systems in this area. Utilities are reducing their dependency on fossil fuel generation and shifting to renewable and battery storage systems for ancillary services. Energy storage-as-a-service plays a critical role in providing ancillary services to the grid, which are necessary for maintaining grid stability, reliability, and efficiency. Ancillary services include a range of support functions such as frequency regulation, voltage control, spinning reserve, and others, which help balance supply and demand, especially as renewable energy sources become more prevalent.

End Use Insights

Based on end use, the industrial, residential & commercial segment led the market with the largest revenue share of 69.6% in 2025. The ESaaS model is widely adopted by the industrial sector for reliable power generation and stable energy supply. Meanwhile, larger housing societies and remote residential areas utilize these services to ensure a consistent power supply and lower energy consumption costs. The increasing adoption of solar panels by homeowners presents a notable avenue for market growth. ESaaS can be leveraged to store excess solar energy produced during the day for use during nighttime or on cloudy days.
