From Toshiba Secures Orders for Mongolian Renewable Energy Grid Upgrade

How could Toshiba's energy systems deployment in Mongolia affect Rio Tinto?

Possible What happens if… A possibility worth considering, not a forecast.

Improved Mongolian power infrastructure may lower operational costs for Rio Tinto Toshiba's project is establishing a model for stable urban electricity supplies in Mongolia by integrating solar power and battery storage into a microgrid. This initiative addresses Mongolia's challenges, including rising electricity demand and transmission losses. By improving the overall stability and renewable share of the national grid, the project reduces the operational risks and energy costs associated with heavy industry, which is critical for mining operations like those run by Rio Tinto.

The facts so far

As reported. Each one links to where it comes from.

  • Toshiba secured orders for energy management and high-power battery storage systems for a Japanese government grant-funded project in Mongolia.ibtimes.com
  • The Darkhan substation installation targets December 2027 startup, supporting electricity supplies to Darkhan, Erdenet and Ulaanbaatar.ibtimes.com
  • The project aims to establish a model for stable urban electricity supplies with a higher renewable-energy share by integrating an adjacent solar power plant and battery storage into a microgrid.ibtimes.com
  • Mongolia faces rising electricity demand, transmission losses between power plants and distant consumption centres, ageing coal-fired power stations and increasing electricity imports from neighbouring countries.ibtimes.com

Why it matters

For Rio Tinto, which relies on large-scale industrial operations, energy stability is paramount. The current challenges in Mongolia—including rising demand and transmission losses—pose operational risks that can lead to costly downtime or reliance on less efficient power sources. A successful transition to a stable, renewable microgrid could significantly de-risk these operations and stabilize long-term energy expenditure.

Globally, the push for renewable energy integration in developing economies is a major trend. This project aligns with Mongolia's target of raising renewable energy to 30% of installed generating capacity by 2030. The success of this model could influence how other energy-intensive industries plan their infrastructure investments in the region.

What we don't know yet

  • What is the projected impact of the microgrid on the overall national grid stability?
  • Will the improved energy infrastructure be available to industrial zones outside of Ulaanbaatar and Darkhan?

What would change this answer

The project successfully meets its December 2027 startup target at the Darkhan substation.This would confirm the viability of the microgrid model, increasing the likelihood of wider adoption and greater benefits for industrial users.
The Japanese government reduces funding for the grant-funded project.The scope and timeline of the infrastructure improvements could be curtailed, diminishing the potential benefits for mining operations.
