According to the TechSci Research report titled “Hydropower Generation Market – Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2030F”, the Global Hydropower Generation Market was valued at USD 431.8 billion in 2024 and is projected to reach USD 621.5 billion by 2030, growing at a CAGR of 6.1% during the forecast period. This growth is fueled by a global shift toward clean energy, driven by rising environmental awareness, increasing energy demand, and the urgent need to reduce dependence on fossil fuels.
Hydropower continues to be one of the most reliable and established renewable energy sources, offering consistent base-load power, particularly in countries with abundant freshwater resources. As nations strive for energy independence, hydropower presents a dependable, domestically-sourced energy option that minimizes reliance on imported fossil fuels. Its stability and flexibility make it a cornerstone in energy transition strategies, especially as global electricity needs surge due to urbanization, electrification, and industrial growth.
One of the most critical aspects contributing to hydropower’s rising importance is its role in energy storage and grid stability. Pumped storage hydropower systems act as large-scale batteries, storing excess energy generated from intermittent renewable sources such as solar and wind. These systems help balance electricity supply and demand, enhancing the reliability of national grids. As the penetration of solar and wind energy increases, so does the need for flexible, fast-response backup systems—further cementing hydropower’s integral role in modern energy infrastructures.
Environmental sustainability and climate change mitigation are also significant market drivers. Hydropower has a notably low carbon footprint compared to fossil-fuel-based energy sources, contributing significantly to the reduction of greenhouse gas emissions. In the context of global climate commitments and net-zero goals, hydropower is seen as an essential technology in national and international clean energy roadmaps. The combination of long-term cost-effectiveness, low emissions, and operational longevity makes hydropower a strategic investment for governments and energy providers alike.
Capacity Insights
By capacity, the Medium Hydro Power Plant segment—typically ranging from 10 MW to 100 MW—led the market in 2024 and is expected to maintain its dominance through 2030. Medium hydro power plants strike an optimal balance between cost-efficiency, scalability, and environmental impact, making them ideal for both developing and developed markets.
Unlike large-scale hydropower projects, which often involve complex and capital-intensive infrastructure, medium hydro plants require comparatively lower investments and shorter development timelines. This makes them particularly attractive to nations looking for faster returns and accelerated progress toward renewable energy targets. These plants are often deployed in areas with moderate water flow and are well-suited to decentralized energy needs, including off-grid and rural electrification programs.
The adaptability of medium hydro plants to various geographies and hydrological conditions enhances their global appeal. Furthermore, governments across several regions are introducing favorable policies, tax incentives, and subsidies to promote renewable energy, including hydropower. This regulatory support, combined with technological advancements in turbines and control systems, is driving the widespread adoption of medium hydro projects.
Environmentally, medium-sized hydro plants are generally less invasive than their large-scale counterparts. They do not typically require the extensive damming or flooding of ecosystems, thus minimizing ecological disruption. As a result, these projects are more likely to receive regulatory approval and community support. They also integrate well with other sustainable agricultural and industrial practices, making them a vital tool in regional green energy strategies.

Regional Outlook: Asia Pacific Leads Growth
The Asia Pacific region is emerging as the fastest-growing market for hydropower generation. This growth is driven by a blend of strong economic expansion, rising electricity demand, and robust policy frameworks aimed at enhancing renewable energy infrastructure. Key countries such as China, India, and Indonesia are at the forefront of hydropower development.
China, which holds the world's largest installed hydropower capacity, continues to lead regional investments with massive projects such as the Three Gorges Dam and the Baihetan Hydropower Station. The Chinese government views hydropower as a critical element of its clean energy future, helping to reduce reliance on coal and support the nation’s carbon neutrality goals.
In India, hydropower is being aggressively promoted as a sustainable solution to growing power demands. The government has initiated several policies and funding mechanisms aimed at revitalizing existing hydroelectric assets and developing new projects. Hydropower is also seen as vital for balancing the country's increasing adoption of solar and wind power, providing reliable baseload and peaking power.
The geographical advantages in Asia Pacific—such as vast river systems, mountainous terrain, and monsoon-fed water resources—support the development of large-scale and medium-scale hydropower installations. Beyond the major economies, countries like Nepal, Bhutan, Myanmar, and Vietnam are also exploring hydropower opportunities to boost domestic energy security and even export power to neighboring countries.
Moreover, the growing interest in decentralized and small-scale hydropower systems across rural and remote regions is adding another layer of growth in the region. These installations are often community-driven and supported by international development agencies,
