With the latest deal, the Philippines has procured cumulative 6 GWh of battery energy storage systems (BESS) within days. China’s Huawei has bagged its biggest BESS order to date and will supply the Meralco Terra Solar Project in the Philippines, which is considered the largest integrated solar and battery storage facility in the world.
Terra Solar Philippines has signed a BESS supply agreement with Huawei International for the 3,500 megawatt MTerra Solar project.
Huawei has secured a supply agreement to provide a 4.5GWh BESS for the Meralco Terra Solar project in the Philippines.
The BESS supply agreement marks Huawei’s largest to date. Construction started on the Meralco Terra Solar solar-plus-storage project in November 2024. The site is claimed to be the world’s largest integrated power plant that combines the two technologies.
Tycoon Manuel V. Pangilinan’s Meralco PowerGen Corp. (MGen) has tapped Singapore-based Huawei International Pte. Ltd. to deliver the battery energy storage system component of the MTerra Solar project.
Next-generation energy solutions Huawei’s advanced energy solutions, showcased in projects like Saudi Arabia’s Red Sea solar microgrid, are set to play a key role in MTerra Solar in the Philippines. These systems will enable MTerra to efficiently store energy during low demand and stabilize grid supply during peak periods.
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.
