Public transportation companies could save money by using LTO batteries made by ABB

24 September 2022

The public transportation companies could save a significant amount of money by adopting the energy-saving solutions provided by Swiss company ABB. The company has developed LTO (lithium-titanate-oxide) batteries used in energy storage systems but also in in-house-developed power supply systems for electric buses, light-rail transit systems and mining rail vehicles.

”To extend the catenary in two directions, the investment needed is around half a million euro, but if these companies chose for a storage system produced by ABB the price drops to 250.000 euro”, according to Nicușor Stan, Local Sales Manager, ABB România, at the conference “Regional Approach Sofia – Energy Goes Both Ways”, organized by Energynomics.

For LTO batteries, ABB adopts battery cells produced by Japan-based Toshiba. LTO batteries have much longer service lives than LFP ones and can be recharged more than 20.000 times.

”The warranty for these batteries extends over a period of 15 years, but after eight years ABB is evaluating it and if its capacity is less than 80%, ABB is replacing it”, Stan added.


ABB has an LTO battery factory in Switzerland, with annual output hiked from 25MWh in 2019 to 50MWh in 2022 and to be further hiked to 75MWh in 2023.

The conference “Regional Approach Sofia – Energy Goes Both Ways” was organized by Energynomics with the support of our partners: ABB România, Electro-Service RB, Kawasaki Gas Turbine Europe, Signify.
