From grid supply to green buses - people power is driving Transit Systems forward
ELECTRICAL ENGINEERING KEY TO Transit Systems FUTURE
As Transit Systems continues to create fully electric fleet hubs across Australia, they recognise it is their people power that helps them create and deliver the country’s largest electrification blueprints.
Mark Peters, Transit Systems Executive General Manager Business Operations, said the ongoing success with their Zero Emission Bus transition is made possible by leveraging the latest advancements in new technology, but it is optimised by the talented people driving the change.
With support and funding from government partners including Transport for NSW, at the forefront of the technical transition for Transit Systems in NSW is Krizell Aligam, an Electrical Engineer.
Mr Peters said Krizell’s unconventional pathway from power grid analysis to public transport illuminates the possibilities of innovation and diversity in the industry.
FROM POWER SYSTEMS TO PASSENGER NETWORKS
A native of the Philippines, Krizell began her career in complex electrical power systems, specialising in grid studies, load flow, and network analysis. Her transition to the bus industry was born from curiosity and a desire to contribute directly to her new community.
“When I moved to Australia, I was impressed by how advanced the public transport system was.
“I wanted to apply my engineering skills in a way that directly contributes to sustainable transport and the community. The opportunity to get hands on experience in the construction and roll-out of zero-emission buses really stood out,” she said.
Mr Peters said Krizell’s role is a key part in fully electrifying depots.
THE BLUEPRINT FOR A GREENER TOMORROW
All electrification project is more than just installing chargers; they depots become major industry achievements and set new benchmarks for large-scale, sustainable public transport infrastructure.
Krizell said the most exciting part of her role is knowing that the work is not just theoretical; it directly supports a cleaner environment and the community.
“One of the key innovations in modern depot planning lies in the space-efficient infrastructure design. Projects feature compact structures such as cable chambers, as well as an elevated plant decks that house transformers and electrical equipment supplying power to the chargers.
“These solutions optimise often limited depot space while supporting a high-capacity, fully electric fleet,” she said.
ENGINEERING FOR COMMUNITY IMPACT
Electrification requires intricate collaboration, a process Krizell highlights as essential. "Teamwork really does make the dream work," she said.
"Delivering a project of significant scale takes close collaboration, bringing together technical experts, industry specialists, and operations teams to work towards one shared goal: a smarter, cleaner, and more sustainable public transport infrastructure.”
There are multiple positive impacts of zero-emission depots:
· For customers: Quieter rides, less vibration, and zero sooty exhaust contribute to a more comfortable, high-quality commuting experience.
· For operations: Depots operate “smarter,” using real-time telematics data to optimise energy use, scheduling, and battery performance.
· For our people: Drivers and mechanics gain new, future-focused skills in high-voltage systems and advanced technology.
THE LEGACY OF INNOVATION
Krizell is proud to be part of Transit Systems, which she believes is leading the way through a deep commitment to innovation, showcased by projects from the first Hydrogen Fuel Cell Bus trials to the operation of over 120 electric buses.
“I hope projects like this will be seen as key milestones in Australia’s journey toward decarbonisation.
“The transport sector is a major part of the emissions challenge, and every step we take toward electrification helps create a cleaner environment, high-quality communities, and a more sustainable transport for everyone.
Krizell added that Transit Systems is not afraid to explore, test, and adapt new technologies.
“Whether it’s the latest in electric buses, hydrogen fuel cell buses, charging infrastructure, telematics, or charging management software - that willingness to embrace change and push boundaries keeps Transit Systems at the forefront of sustainable transport in Australia,” she said.
