China has emerged as a global leader in pumped storage technology, which is the most mature solution for large-scale, long-duration energy storage. By the end of 2024, the State Grid Corporation of China had 40.56 GW of operational pumped storage capacity, with an additional 53.48 GW under construction.
When fully charged, the upper reservoir can store enough energy to power the plant at full capacity for 10.8 hours, equivalent to nearly 40 GWh. This makes Fengning the most significant pumped storage facility in North China in terms of balancing renewable energy output.
The Fengning pumped storage power station fits the goal. China is putting efforts to expand its pumped hydro energy storage over the next decade, aiming to have 62 gigawatts of storage facilities operating by 2025, and 120 gigawatts by 2030, according to a plan published by the National Energy Administration in September.
It features a seamless switch between electric, solar, wind, and water potential energy. The hydropower station will provide green electricity to the power grid covering Beijing, Tianjing and the northern part of Hebei Province.
In August 2023, the U.S. Energy Information Administration credited pumped storage with increasing the flexibility of China’s power grid. That made it “particularly important in China, which has a large and growing share of wind and solar power in its generation mix,” the EIA said at the time.
The plant, which had been under construction since May 2013, was originally meant to support the 2022 Beijing Winter Olympics, the International Hydropower Association (IHA) states.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
