As a leading global supplier of e-mobility technology, ABB worked with Milan’s public transport company ATM (Azienda Trasporti Milanesi) to deliver a turnkey solution for its San Donato depot. This is the first of four fully electrical depots planned for the city and a pilot site for innovative new charging solutions. Designed with sustainability and longevity in mind, the installation at San Donato will help ATM meet its forecast to reduce diesel demand by 30 million liters per year and cut CO2 emissions by 75,000 tons per year by 2030. ABB’s Terra 124 chargers have been installed in the depot’s parking area. One charger can fast charge two vehicles at the same time, optimizing the installation cost and minimizing impact. The e-buses are scheduled to charge during the night when it is more cost effective, and with a range of up to 180km in normal conditions, this is enough for the e-buses to remain in use all day without the need for interim charging. As the pilot charging site is focused on using the most innovative and energy efficient solutions, ABB’s package also included the installation of a 324 kWh Energy Storage Solution. The ESS allows ATM to manage their grid consumption. It also allows understanding of the use cases for an ESS, when coupled with charging infrastructure, for simulating potential second-life use case for bus battery packs when they are available in the future. To complete the installation an ABB EV Site Solution controller was commissioned. It optimizes the ESS recharging process while minimizing energy demand and reduces operating costs by controlling in real time the total peak consumption. The ABB Ability Connected Services Portfolio of digital solutions, which allows for remote diagnosis and management of the chargers, was also utilized, helping improve and extend its operating life. In addition, ABB supplied its medium-voltage UniSec air insulated switchgear with its innovative AirPlus insulation gas inside the apparatus. An alternative to SF6, the world’s most potent greenhouse gas, AirPlus can reduce the global warming impact by almost 100 percent.
