Decentralized Energy System Global Market Report 2025

The decentralized energy system market size has grown rapidly in recent years. It will grow from$339.91 billion in 2024 to $386.95 billion in 2025 at a compound annual growth rate (CAGR) of 13.8%. The growth during the historic period can be attributed to increasing energy demand, declining costs of renewable energy technologies, the need for enhanced energy security, government incentives, and a growing consumer preference for green energy.

The decentralized energy system market size is expected to see rapid growth in the next few years. It will grow to$643.86 billion in 2029 at a compound annual growth rate (CAGR) of 13.6%. The growth in the forecast period can be attributed to the increasing adoption of electric vehicles, the expansion of smart grids, stricter carbon regulations, decentralization of power markets, rising energy prices, and a growing demand for energy independence. Major trends during this period include the use of blockchain for energy transactions, artificial intelligence (AI)-powered energy management, advanced battery storage solutions, smart inverters, Internet of Things (IoT)-enabled energy devices, integration of hydrogen systems, and the implementation of predictive maintenance tools.

The rising demand for renewable energy is expected to boost the growth of the decentralized energy system market in the future. Renewable energy is produced from natural sources that are continuously replenished, including sunlight, wind, water, geothermal heat, and biomass, providing an environmentally friendly alternative that lowers greenhouse gas emissions. This demand is growing due to increasing environmental concerns and the necessity to reduce greenhouse gases, as renewable energy generates little to no emissions, making it a cleaner and more sustainable substitute for fossil fuels. Decentralized energy systems support renewable energy adoption by enabling local generation of power, which is especially useful in remote or off-grid locations. These systems improve energy resilience by integrating sources like solar and wind, enhancing efficiency, and lessening dependence on centralized grids. For example, in March 2025, the International Renewable Energy Agency (IRENA), a United Arab Emirates-based intergovernmental organization, reported that global renewable energy capacity increased from 3,862,881 megawatts (MW) in 2023 to 4,448,051 megawatts (MW) in 2024. Thus, the growing demand for renewable energy is driving the expansion of the decentralized energy system market.

Leading companies in the decentralized energy systems market are developing advanced technologies, including smart energy solutions, to improve energy efficiency, enable real-time monitoring, and optimize energy distribution within decentralized grids. Smart energy solutions are technology-driven systems that enhance the generation, distribution, and consumption of energy using advanced tools such as the Internet of Things (IoT), artificial intelligence (AI), and renewable energy integration to boost efficiency and sustainability. For instance, in February 2025, ENVIRIA Energy Holding GmbH, a Germany-based renewable energy firm, introduced PeakHive, a smart energy solution that integrates renewable energy sources, storage, and digital management to promote energy independence and sustainability. This solution offers lower energy costs, greater self-sufficiency, and potential revenue streams through innovative leasing models.

A decentralized energy system is an energy network where power generation and distribution occur locally, often utilizing renewable sources such as solar, wind, or small-scale hydro. Its primary goal is to improve energy security, decrease dependence on centralized grids, and enable more efficient and sustainable energy management by allowing communities or individuals to generate and consume energy on-site. These systems typically incorporate smart technologies and energy storage solutions to optimize both energy production and consumption.

The main types of decentralized energy systems include wind power, hydropower, solar power, combined heat and power (CHP) and other thermal power stations, bioenergy, geothermal energy, and other variants. Wind power involves generating electricity through small-scale wind turbines situated close to where the energy is used, rather than relying on large centralized wind farms. The technologies involved encompass solar photovoltaic, wind turbines, combined heat and power, energy storage, and other innovations. Applications cover various sectors including industries, commercial establishments, large buildings, municipalities, and communities. Key end users include utility providers, independent power producers, microgrid operators, and others.
