Client industryLocal Government
The BriefThe 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 ApproachEvenergi 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:
  • Project background/preparation
  • Low-emission vehicle suitability analysis
  • Infrastructure analysis
  • Review of value-added services and co-benefits of project
  • Synthesis of data and provision of a detailed fleet transition plan
The ResultBreakthrough 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.

The BriefIn anticipation of the demand for electric vehicles increasing, and the future application of vehicle emission standards, the City wished to establish a pathway for the transition of the City’s own internal vehicle fleet to a low carbon and electric vehicle fleet where practicable.

Requirements included

  • The development of a pathway for the City to transition to electric vehicles (EV’s) to be integrated with existing goals and targets
  • To undertake an assessment of existing fleet infrastructure and usage requirements, including mileages travelled, range of vehicle types, fuel consumption and costs, maintenance requirements and costs, emissions intensity of vehicle types, total emissions from vehicle fleet based upon vehicle motor type and km’s travelled
  • Identification of alternative low emission vehicle options (EV’s) detailing costs, km range, battery types well as recharge technology options and power requirements at site
  • Guidance to decision makers for cost impacts of energy technology and systems
The ApproachEvenergi collated all the data associated with the City’s fleet including passenger vehicles, light commercial vehicles (LCV’s) and heavy use vehicles. The energy and emissions profile was assessed for vehicle types collectively, establishing the most recently available data as a benchmark for future comparative analysis. Approach included:
  • Overall fleet suitability analysis
  • Understanding current  Fleet policies and processes
  • Determining fit for purpose vehicles
  • Data collection and analysis
  • Detailed fleet analysis – Range suitability of vehicles
  • Run potential optimisations/models
The ResultEvenergi’s abilities to forecast the future energy demand for Bendigo’s recharge requirements led to the most cost effective pathway for the transition of the City’s own internal vehicle fleet to a low carbon and electric vehicle fleet

Go Ahead Singapore currently operate Loyang depot, which contains close to 400 buses. Go-Ahead singapore runs 30 routes in Singapore with over 900 employees and a contract value of over $500 M 
Product or services providedZET Advisory


Client industryBus Operators
The BriefThe 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 ApproachGo-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 ResultEvenergi 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.

The BriefTo provide a projection of electric vehicle maximum demand impacts by postcodes in Ausgrid’s network (225 postcodes in total) that can be used as an input to Ausgrid’s post model adjustment for the zone substation spatial demand forecast for 2020.
The ApproachEvenergi, with the collaboration of Ausgrid, has built a bottom-up modelling tool (GridFleet) for predicting the impact of electric vehicles on distribution Networks. By applying the fundamental principles and algorithms of GridFleet’’s typology-based methodology, the following method was adopted to deliver this project:
  1. Project electric vehicle maximum demand impact based on data obtained for each of the 225 postcodes in the Ausgrid license area based on data obtained from key data sources such as Australian Bureau of Statistics and Ausgrid zone substation interval data.
  2. Produce hourly interval typical load profiles for summer weekday, summer weekend, winter weekday and winter weekend out to 2040
  3. Provide scenario modelling for the five scenarios identified in the Integrated System Plan
The ResultThe data was used by Ausgrid in its submission to the Australian Energy Market Operator for billions of dollars of annual investment  and will help drive better investment decisions around network planning.

The BriefEvenergi was commissioned by Essential to create a forecast of the potential impact of electric vehicles on their network. Essential’s network is vast and diverse as it spans most of the regional NSW, containing long interconnecting lines with small loads, as well as large regional centers.
The ApproachThis work involved mapping future EV infrastructure within Essential’s network, looking at both the impacts that local EV uptake will have in regional centers as well as inter-regional travel that will cause holiday peaks in areas that may not have the electrical network capacity to support them.

The approach involved:

  • Electric vehicle adoption forecasting
  • Validating access to power
  • Infrastructure planning and investment in charging infrastructure networks
  • Reporting and presentations
  • Charging infrastructure economic modelling
  • Charging infrastructure strategic planning
Short descriptionEvenergi was commissioned by Essential to create a forecast of the potential impact of electric vehicles on their network. This involved mapping future infrastructure across the entire network
OutcomeElectrical load profiles were developed out to 2040 and provided to Essential to include in their forecasting and asset planning. This project gave Essential planners insights into the opportunities to use EV load to better utilise their assets, which in some cases can lead to better energy pricing outcomes for consumers.

Client requirement  Prior to this study, there was no clear way to predict the future impact of electric vehicles on the electricity network in NSW. Evenergi conducted modeling to predict the impact of electric vehicles on distribution networks across 225 postcodes in Ausgrid’s licensed distribution area, using GridFleet’s typology-based methodology.
Evernergi approachThe approach to this project was to:
  1. Forecast EV uptakes for each postcode and by vehicle classification within that postcode (i.e. buses, heavy vehicles, private vehicles, etc.)
  2. Determine how key influencers such as battery range improvement, shifts to carshare, and autonomous vehicles, the capability of vehicles to charge at certain rates, and others will impact the charging behaviors of EVs and the resultant effect this will have on the network.
  3. Develop a set of outputs that can be easily integrated into existing processes and import seamlessly into existing software used by Ausgrid.
  4. Produce half-hourly interval electrical load profiles, split by typology (buses, carparks, DC fast charging, fleets, and residential) and forecast out to 2040.
  5. Deliver an auditable and documented model that the market operator (AEMO) would see as credible.
OutcomeThe project was delivered on time and on budget. A world-first framework was created, along with data collected across the entire network; data that is still being used today.

Subsequent to the program, the product is now being used by several other Network Providers.
