Following selection for KOICA CTS Seed 2 in October 2025, GIGAette signed the agreement and started the project in December 2025. CTS stands for Creative Technology Solution, an innovation program of the Korea International Cooperation Agency (KOICA).
Expanding renewable district heating in Mongolia
The project supplies district heating in Mongolia’s regional cities using renewable energy and thermal batteries. Government support is KRW 700 million, and the project runs from December 2025 through 2027.
It builds on the 1.5 MWh thermal storage system and local partnerships established in Tsetserleg under KOICA CTS Seed 1, expanding the integration of renewable energy and thermal batteries for district heating.
Demonstration plans refined after the agreement
The current plan, refined after the agreement, confirms Tsetserleg in Arkhangai Province as the project location and calls for a 6 MWh IsoTES® district-heating system. Electricity from solar PV will power electric heaters; the resulting heat will be stored and supplied for heating.
Working with local partner EKH Golomtiin, GIGAette is pursuing system fabrication, installation, and operational validation to reduce reliance on coal heating and local air pollution.
