The Brief | KCM has retained Evenergi to conduct predictive energy modeling and in-depot simulation for its to be constructed Interim Base, home to 124 pantograph-only battery electric buses (64 artics, 60 forty-foots).
KCM is commencing a detailed depot design phase utilizing pantograph down chargers. The process involves reviewing alternative designs to understand the most efficient approach to charging on the site now and into the future (including a potential autonomous future). The objective of our work is to provide a framework that establishes the optimal combination of depot layouts, charger speeds and charger types which most benefits KCM. Optimal is defined as the balance between the following factors:

Client industry | Local Government |
The Brief | The key requirement of Brimbank Council’s Fleet Transition Plan (FTP) was to guide a transition of Council’s fleet to zero emissions technologies by providing a business case for the transition of the Council’s vehicles to zero emissions by 2030, and sooner where possible. This fleet included more than 300 Waste Collection, Commercial Trucks, Passenger vehicles, Buses, Utes and Vans. | ||
The Approach | Evenergi developed a clear methodology for delivery of the Fleet Transition Plan based on a combination of direct project experience, interviews with hundreds of Fleet Managers and feedback from Institute of Public Works and Engineering (IPWEA) and the Australian Fleet Management Association (AFMA). Core deliverable steps in this process included:
|
||
The Result | Breakthrough findings show that full electrification across light and heavy fleets is viable by 2030. Evenergi delivered an FTP for Brimbank City Council to integrate the various technical and financial considerations required to successfully implement an accelerated transition to zero-emissions vehicles and infrastructure over the next 5-10 years and maximise the opportunities presented by the transition.
This enabled the Council to maximise the benefits of a planned move to 100% renewable electricity in its operations by 2021 as part of a collaborative power purchase agreement. Client feedback was that it was the best consulting report they had ever seen. |

Client industry | Bus Operators |
The Brief | The LTA were interested to see how this fleet could be electrified and what operational impacts this may have and launched a collaborative process to work with operators to develop the potential future bus electrification strategy. Go Ahead needed a way to quickly analyse their existing bus routes to present some alternatives to the transit authority. They needed a robust answer, and they needed it quickly. | ||
The Approach | 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 BetterFleet, 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 Result | Evenergi developed a fleet transition and infrastructure plan and provided a strategy that will lead to significant investment in new electric buses and infrastructure in Singapore
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. |
