LISINER’s Zhoushan Grid-Scale Energy Storage Project Supports Peak-Summer Reliability

Since the start of summer, persistent high temperatures have driven national power load to repeated record highs. Latest data from the National Energy Administration shows that the maximum national power load has hit 1.506 billion kilowatts, an all-time high, marking the launch of a critical campaign to guarantee power supply.

Recently, LISINER Zhoushan standalone energy storage facility was featured by local television for its role in supporting the island region through peak summer power demand.

Supporting Reliable Island Power During Summer Peaks

As the largest single-unit standalone energy storage facility in Zhoushan, the project has an installed capacity of 109.5 MW/219 MWh with an annual power discharge volume exceeding 127 million kWh. Calculated on an annual consumption of 2000 kWh per household, the station can meet the electricity demand of more than 60,000 local households and ensure stable and sufficient power supply during peak summer periods.

Tailored for island environments, LISINER Zhoushan standalone energy storage facility adopts liquid-cooled containerized energy storage systems with C5M protection rating to ensure continuous and stable operation under harsh conditions including high salt spray, high humidity and high temperature.

Supported by long-term stable and all-season adaptable operation capacity, the power station provides critical buffering and security guarantees for the regional power system. With precise energy storage control, it discharges power rapidly to cope with peak loads during high-demand periods and charges efficiently to store energy during off-peak hours. Through peak shaving, valley filling and fluctuation mitigation, it delivers stable support for Daishan Island and surrounding areas.

Unlocking Multiple Revenue Streams from Flexible Capacity

At critical moments during peak summer power demand, relying on intelligent dispatching and second-level response capability, the power station participates in real-time grid tasks such as peak shaving, frequency regulation and emergency standby, significantly enhancing grid resilience.

The project has taken part in market-oriented power trading since grid connection, converting electric energy into substantial returns. It generates economic gains while guaranteeing power supply, supporting improvements to the local energy mix and regional economic development.

Support, Accommodation and Buffering to Break the Bottleneck of renewable energy integration on Islands

In recent years, leveraging marine resources, Daishan has vigorously developed clean energy including offshore wind power, fishery-solar hybrid systems and tidal current energy. Nevertheless, the intermittency of power generation and insufficient grid regulation capacity once created bottlenecks in renewable energy integration.

The operation of LISINER’s energy storage facility effectively equips Daishan’s annual 1.8 billion kWh of clean power with an extra-large capacity buffer, enabling the practical implementation of the multi-energy complementary model of wind, solar, energy storage and hydrogen.

As pointed out in the TV news report, the power station has become an indispensable part of Daishan’s energy system. While improving grid stability, it also transforms clean energy from weather-dependent power generation to adjustable power supply on demand.

From Daishan’s first independent energy storage station to a new benchmark for island energy security, this power station has not only safeguarded stable power supply for thousands of households this summer, but also laid a solid foundation for building a more resilient and greener power system in the future.

LISINER will continue to leverage leading energy storage technologies and power operation capabilities to support the improvement of local energy resilience and facilitate the intelligent and green transformation of the energy system. Guided by the philosophy of Concentrate on Micro-grid, Serve the Power Grid, the company will contribute to the high-quality development of China’s energy sector.
