A Sustainable Asset Valuation (SAVi) Assessment of Bus Fleet Electrification in Ulaanbaatar, Mongolia: Summary for the Ministry of Road and Transport in Mongolia

This executive summary presents a Sustainable Asset Valuation (SAVi) assessment of the full electrification of the public bus fleet in Ulaanbaatar, Mongolia, by 2050. The analysis compares a baseline electrification scenario against two scenarios involving a modal shift from private vehicles to public transport, quantifying the socio-economic and environmental benefits over a 25-year period (2025–2050).

• Full electrification of Ulaanbaatar's bus fleet without a modal shift is projected to yield a cumulative, discounted (at 5%) net benefit of MNT 93,355 million (USD 26.3 million) over 25 years (2025–2050), with an integrated benefit-to-cost ratio (BCR) of 1.09.
• Integrating a modal shift from private vehicles to public buses significantly increases the project's economic viability. A 5% modal shift increases net benefits to MNT 1,422,992 million (USD 400.5 million) with a BCR of 2.36, while a 10% shift raises net benefits to MNT 2,752,629 million (USD 774.8 million) and the BCR to 3.63.
• The primary economic driver for electrification is the avoidance of fuel costs, valued at a cumulative, discounted MNT 816,011 million (USD 229.6 million). The second largest impact is reduced maintenance costs, valued at MNT 162,358 million (USD 45.7 million).
• Additional avoided costs resulting from electrification include CO2 emissions (MNT 67,364 million or USD 18.9 million), noise pollution (MNT 37,669 million or USD 10.6 million), and air pollution (MNT 32,539 million or USD 9.1 million).
• The transition requires a significant increase in the number of electric buses, moving from a current fleet of 90 electric buses to a fully electrified fleet of 1,303 buses by 2050. This involves high capital expenditures, totaling a cumulative MNT 709,270 million (USD 199.6 million) until 2050.
• The assessment highlights that traditional infrastructure assessments often underestimate the value of such projects; if only fuel and maintenance savings are considered, the BCR for the electrification project drops to 0.94.
