On November 13, 2026, on the screen of the Manila power grid dispatch hall, the current curve of the inter island transmission line was still fluctuating. The State Grid Corporation of the Philippines has handed over an EPC contract for a 100MW/400MWh energy storage power station to Sifang Corporation. For the Philippine power grid with scattered islands and weak grid structure, it is not as simple as adding an additional battery station, but adding a buffer zone that can stabilize voltage and frequency to fluctuating new energy.

Island weak network to be resolved

The Philippines is composed of numerous islands, and the main grid connection is not close enough. Whenever there is a fluctuation in the output of new energy, the voltage and frequency are easily disturbed. Traditional grid connected energy storage mainly follows the signal action of the power grid and has limited support capacity in weak power grids. The Philippine Department of Energy has issued regulations that require new energy projects with a capacity of over 10MW to be equipped with storage facilities, and the new version of the power grid regulations also includes technical requirements for grid construction. The direction of upgrading the local power grid coincides with the technical route of this bidding.

Energy Storage Society stabilizes the network

This project adopts a full capacity grid construction route, where energy storage is no longer just passive charging and discharging, but can provide voltage and frequency reference when needed by the grid, with inertia support, fault ride through, and black start capabilities. After the power station is connected to the main grid in the Philippines, it will undertake functions such as frequency and voltage regulation, peak shaving and valley filling, system backup, and new energy consumption. The entire delivery chain, from drawing design, equipment selection to civil construction, system integration, joint debugging and delivery, to technical support after commissioning, is coordinated by Sifang Corporation. For Sifang Group, the business boundary has also extended from traditional secondary equipment and automation systems to the general contracting track of grid supported energy storage.

Raise the threshold for going out to sea

The threshold for large-scale energy storage projects overseas is changing. Tianchuan Weiwang has undertaken a 150MW/150MWh grid connected energy storage project on an isolated island in Indonesia, while Farview's large-scale energy storage project in Germany relies on a new generation platform to adapt to strict grid connection requirements. Both the weak power grid region and the European grid connection system are raising the requirements for the support capacity of the power grid. Compared to standardized cell supply, general contractors who can encapsulate grid operation experience into control systems have higher technical barriers. Sifang Group's winning bid has accumulated engineering experience for China's energy storage technology to participate in the construction of new power systems in Southeast Asia.Editor/Gao Xue
