Case Study: Go-ahead and Singapore Land and Transport Authority


Electric Bus

In 2020 Evenergi was engaged by the Go-Ahead group to assist with bus electrification projects in Singapore.


The Singapore Land Transport Authority (LTA) has made a commitment to the implementation of a clean energy bus fleet by 2040 (including hybrid, electric and hydrogen buses). Go Ahead Singapore currently operate Loyang depot, which contains close to 400 buses. The LTA were interested to see how this fleet could be electrified and what operational impacts this may have.


Go-Ahead and Evenergi worked in partnership to model 60%, 80% and 100% electrification scenarios using scheduling data from the existing fleet of buses.


Using Evenergi’s multi-physics based software GridFleetTM, a digital twin of the depot was created and electrification scenarios were modelled. Very granular modelling was conducted, running every bus on every route and looking at the impacts of factors such as passenger load, air conditioning and vehicle type to determine suitability for electrification.


The results of the modelling have shown that up to 100% electrification of the existing fleet can be achieved with minimal to no impact to the existing operations and Peak Vehicle Requirement (PVR).


Evenergi continues to work closely with the Go-Ahead group and the Singapore LTA today to help support their vision to become a clean energy fleet by 2040.


As one of the UK’s leading public transport providers, Go-Ahead partners with governments, local communities and strategic partners to develop and operate services that create long term value for. As well as its UK rail and bus operations, Go-Ahead currently operates in Ireland and Singapore and has won contracts in Norway and Germany.
