en.Wedoany.com Reported - Recently, the 50MW/200MWh battery energy storage project in Mongolia, undertaken as an EPC (Engineering, Procurement, and Construction) contract by China Energy Engineering Group Anhui No.2 Electric Power Construction Co., Ltd., officially commenced construction.
Located in the Baganuur District of Ulaanbaatar, Mongolia, the project plans to build a large-capacity battery energy storage system of 50MW/200MWh, along with supporting grid-connected transmission lines and substation bay expansion and renovation works. The scope covers the entire chain, including full-process engineering design, equipment supply, on-site construction, and system commissioning. China Energy Engineering Group Anhui No.2 Electric Power Construction Co., Ltd., as the EPC contractor, undertakes the full-cycle work, including geological survey, scheme design, centralized procurement of key equipment, civil construction and installation, system commissioning and trial operation, and grid-connected completion acceptance.
In the absence of a mature electricity market, the project adopts a BOT (Build-Operate-Transfer) model, where the government pays the project company for "available capacity" and "grid services" through fiscal payments. Its core value is anchored in public benefits such as enhancing grid stability, reducing load shedding, replacing high-cost imported electricity, and improving people's livelihoods.
Once completed, the project will provide up to 4 hours of uninterrupted power supply daily, benefiting approximately 25,000 households. It will effectively strengthen the peak-shaving and frequency-regulation capabilities of Mongolia's power grid, significantly expand the capacity for integrating new energy sources such as local wind and solar power, accelerate the green transformation of the local energy structure, and empower the sustainable development of regional clean energy.
