A New Chapter in Energy: Mangla Village Energy Storage Station Successfully Completed Black Start Test, Boosting the Grid Security

March 20, 2026

From “passive response” to “proactive action,” energy storage stations are becoming a key component of the power grid’s emergency support system.

Recently, the Mangla Village Energy Storage Station in Yunnan completed a plant-level black start test. This milestone indicates that the 150MW/300MWh “mega power bank” now has the capability to self-start and restore power supply under extreme conditions, adding a crucial layer of security to the regional grid.

What is Black Start? The “Pacemaker” of the Power Grid

Black start refers to the process of restoring power to a grid after a complete shutdown, without relying on external grid support, using power sources for self-starting.

Much like defibrillation after cardiac arrest, black start serves as the last line of defense in the power system’s safety framework.

Traditionally, this role was fulfilled by hydropower plants and gas turbine plants. Today, electrochemical energy storage stations thanks to their fast response and flexible control, are a new option for black start.

The Mangla Village station’s black start capability means that even in a worst scenario of total grid collapse, it can “wake itself up” and gradually restore power to the surrounding grid.

Project Overview: A Giant “Power Bank” in the Mountains

The Mangla Village Energy Storage Station is located in Yongkang Town, Yongde County, Yunnan Province, and is an important part of the Yongde shared energy storage project.

With a total installed capacity of 150MW/ 300MWh, the project represents a significant investment and can supply electricity to tens of thousands of households simultaneously.

The station adopts advanced lithium iron phosphate (LFP) battery technology, featuring:

· 60 sets of GridUltra 5016 liquid-cooled battery containers

· 30 sets of 5000 kW power conversion and step-up units

· 1 GridHub EMS (Energy Management System)

These systems act as the “central nervous system” of the station, precisely controlling the storage and release of electrical energy.

Technical Insights: How is Black Start Achieved?

Black Start Path Design

The black start path is carefully designed as follows: #1–#5 feeder line energy storage systems [EJ1] → 35kV Bus I → main transformer low-voltage side → station service transformer load

This forms a complete internal power supply loop. The sixth feeder line serves as a simulated load to verify load-carrying capability.
