Cornwall Transit Predictive Performance Modelling and Fleet Electrification Analysis

The Problem

Cornwall Transit, a bustling transportation system, faced challenges maintaining speed and performance. With a passenger influx of 900,000 annually, an effective solution was needed to enhance operation efficiency while reducing greenhouse gas emissions.

In their Energy Conservation and Demand Management Plan 2019-2023, the City of Cornwall has committed to developing and implementing a strategic energy management plan to reduce energy consumption and its related environmental impact. As part of the Plan, the city is targeting a reduction of 10 per cent of their fuel and electricity consumption in all municipal operations by 2023.

The Objective

To achieve sustainable improvement, Cornwall Transit introduced a project integrating electric buses into their fleet. Their aim was to optimize energy efficiency, reduce GHG emissions, and decrease operational costs while ensuring dependable transportation for the community.

In order to meet their decarbonization goals, the City of Cornwall hired CUTRIC to perform a full fleet block based modelling study. The project included a literature review of BEB landscape, energy analysis of ZEB configurations using in-depot and on-route charging, economic analysis estimating electricity usage costs, GHG emission analysis, schedule analysis of opportunity charging, ease of electrification and recommendations for short-term and long-term planning processes.

The Results

  • By implementing this groundbreaking initiative, Cornwall Transit witnessed remarkable outcomes. The average energy efficiency of the 40-foot bus on medium duty ranged from 1.49 to 1.68, while the 25-foot BEB achieved an impressive efficiency of 0.56 to 0.57. Notably, the project led to a 97% GHG emission reduction for the 40-foot BEB and an astounding 99.7% reduction for the 25-foot BEB compared to diesel counterparts.
  • In addition, monthly operational costs for the electric buses were reduced to $22,898 for depot-only charging and $27,635 with depot and opportunity charging, resulting in significant savings. Furthermore, Cornwall Transit observed great success in electrifying 50% of their blocks, albeit with the remaining 50% proving to be challenging.
  • To fully achieve 100% electrification through depot-only charging, additional BEBs will need to be procured to replace existing diesel buses. Alternatively, on-route charging can be explored; however, it would necessitate substantial schedule adjustments to facilitate opportunity charging.
  • With diesel costs amounting to $325,619.27 per year, the project demonstrated substantial financial benefits. The total energy demand for the 40-foot bus on medium duty was 1,377,048.50 kWh per year, while the 25-foot bus required 19,860 kWh per year.

Cornwall Transit’s forward-thinking approach in embracing electric buses has paved the way for a greener and more efficient transportation system, positively impacting both the environment and the community it serves.
