Recently, Terra Solar, a subsidiary of MGEN Renewable Energy, announced that it has signed an agreement with Huawei for the MTerra Solar project. 4.5 GWh battery energy storage system supply agreement.

According to reports, the 3.5 GW MTerra Solar project and the 4.5 GWh battery energy storage project are expected to attract a total investment of US$6.1 billion. The engineering, procurement, and construction contractor is China Power Construction Corporation, and the facilities will be sited at five locations across Nueva Ecija and Bulacan provinces, approximately 92 kilometers north of Manila, the capital of the Philippines. Together, they are poised to become the world’s largest integrated solar-plus-storage project.

According to available information, the project will commence commercial operations in phases, with Phase 1 scheduled to begin in February 2026 and Phase 2 slated for February 2027.

Since 2024, Huawei has been highly active in the energy storage sector, first launching new commercial and industrial energy storage products, followed by the release of grid-forming technology and related use cases.

In the technology domain, Huawei has introduced the C2C dual-chain security architecture, which comprehensively redefines security design from the cell level all the way to system-level applications, thereby delivering end-to-end security assurance across the entire product-to-system value chain. This architecture features dual-layer protection—electrical-chain security and thermal-chain security—including dual-cell monitoring, six-sided high insulation at the pack level, and five-level overcurrent protection at the system level. These measures effectively prevent and isolate electrical risks while leveraging thermal-management technologies to mitigate the risk of thermal runaway.

This year, Huawei launched its Wind–Liquid Intelligent Cooling System for industrial and commercial energy storage, which features three operating modes—active liquid cooling, natural air cooling, and waste heat recovery—and can automatically adjust based on ambient temperature and battery operating conditions, enabling “heart-rate–like” adaptive control. This system design reduces auxiliary power consumption and extends the service life of the energy storage system to 15 years.

In the source-grid-side system, Huawei has adopted a brand-new “Power Actuarial” power supply architecture that leverages fine-grained management and intelligent optimization algorithms on both the DC and AC sides to achieve more efficient energy control and superior power delivery performance. This architecture supports 1.3x overload capability, effectively reducing initial capital expenditure, while its advanced harmonic mitigation algorithm meets the industry’s highest Class B standards and enables parallel operation of multiple units.

Leveraging “intelligentization + grid-formation technology,” Huawei’s intelligent photovoltaic–wind–storage generator system can support stable grid operation and increase the integration capacity of new energy by 40%. According to calculations for a project in Qinghai, when SCR = 1.5, compared with the conventional solution, the intelligent string-based Grid-forming energy storage It is possible to deliver an additional 40% of renewable energy power. Excluding the initial investment in energy storage equipment, the full lifecycle cost can be reduced by RMB 150 million per 100 MWh, equivalent to a cost reduction of RMB 1.5 per Wh.

In Saudi Arabia’s Red Sea region, Huawei has successfully deployed the world’s largest photovoltaic–battery microgrid project, showcasing its technological prowess in large-scale energy-storage initiatives. These innovative solutions highlight Huawei’s technical leadership and industry standing in the energy-storage sector, enhancing the safety and reliability of storage systems while significantly improving energy utilization efficiency and system flexibility—making them suitable for a wide range of commercial, industrial, and residential applications.

In fact, Chinese companies’ overseas orders surged in 2024. Among them, Sungrow Power Supply has already secured several major energy-storage contracts.

On December 6, Sungrow Power Supply secured a 1.5 GWh order from Citicore Renewable Energy Corporation (CREC), marking the largest energy storage system order in Southeast Asia to date. Sungrow will supply CREC with its PowerTitan 2.0 energy storage system, which, when integrated with CREC’s 302 MW photovoltaic project, will enhance PV utilization, alleviate grid congestion, and smooth energy output.

On December 2, Sungrow Power Supply signed major distribution agreements with Raystech and Solar Juice to distribute a total of 1.7 GWh of Sungrow’s commercial and industrial energy storage systems over the next three years.

On November 18, Sungrow Power Supply signed a 4.4 GWh energy storage cooperation agreement with Fidra Energy, covering two flagship standalone energy storage power stations in the UK: the 3.3 GWh Thorpe Marsh project and the 1.1 GWh Westburton C project.

On July 15, Sungrow Power Supply Co., Ltd. successfully signed a contract with Saudi-based ALGIHAZ for the world’s largest energy storage project, with a total capacity of 7.8 GWh. The project comprises three sites located in Najran, Madaya, and Khamis Mushait in Saudi Arabia, with deliveries scheduled to commence in the second half of 2024 and full-capacity grid connection and operation expected in 2025.

Major players such as Huawei and Sungrow Power Supply all entered a “surge” mode for order intake in 2024. Gao Gong Energy Storage believes: First, in the energy storage sector Matthew Effect Increasingly robust, the top 10 players are now capturing more than 80% of the market share—a trend that is becoming a reality. Secondly, global demand for energy storage continues to surge; in addition to the traditional markets of China, the United States, and Europe, demand is also booming in regions such as the Middle East, Southeast Asia, South America, and Australia.
