Technical FAQs 4

Did Mongolia design the first grid-connected battery energy storage system?

A study published by the Asian Development Bank (ADB) delved into the insights gained from designing Mongolia’s first grid-connected battery energy storage system (BESS), boasting an 80 megawatt (MW)/200 megawatt-hour (MWh) capacity.

How much power does Mongolia have?

As of end 2021, Mongolia had 1,549 megawatts (MW) of installed power generation capacity. The country’s energy mix included coal-fired combined heat and power (CHP) plants totaling 1,269 MW (81.9%), renewable energy sources totaling 271.2 MW (17.5%), and diesel power sources totaling 8.6 MW (0.6%).

Can a battery energy storage system be used as a reserve?

The BESS project is strategically positioned to act as a reserve, effectively removing the obstacle impeding the augmentation of variable renewable energy capacity. Adapted from this study, this explainer recommends a practical design approach for developing a grid-connected battery energy storage system. Size the BESS correctly.

What factors determine the power capacity of Mongolia's Bess?

The determination of the power capacity of Mongolia’s BESS was based on two factors: the required regulation reserve for accommodating additional VRE to the CES, and the required standby reserve in case of any grid event. Regulation reserve.
