Roseville Electric Bus Launch Supports Zero-Emission Goals

As electric vehicles (EVs) become increasingly pivotal in the fight against climate change, cities across the United States are embarking on ambitious initiatives to transition their public transportation fleets to zero-emission models. Roseville, California, is leading the charge, demonstrating how strategic planning and community involvement can yield significant environmental benefits. The city's efforts not only aim to meet regulatory requirements but also enhance the quality of life for its residents.

In August 2023, Roseville Transit marked a significant milestone with the launch of its first electric commuter bus. This launch is not just an isolated event; it represents a broader commitment to reducing greenhouse gas emissions and improving air quality for the city’s nearly 150,000 residents. With California mandating that all new bus purchases be zero-emission by 2029, Roseville Transit is proactively replacing its aging fleet with sustainable alternatives, contributing to the state’s ambitious environmental goals.

Citywide initiative towards electrification

The electrification movement in Roseville extends beyond public transit, encompassing a total fleet of over 1,200 vehicles utilized across various city departments, including administrative, refuse collection, emergency services, and utilities. Spearheading this citywide initiative is Brandy LeBeau, fleet manager of Roseville Fleet Services. Under her guidance, the city is transitioning from traditional diesel and gasoline vehicles to alternative fuel models.

LeBeau shared insights into the city’s ongoing efforts: “We’ll be ordering 12 new electric Phoenix buses shortly and have already deployed all-electric Ford F-150 Lightning pickups and Chevrolet Bolts for supervisors and administrative tasks.” The city is also planning to introduce electric vans for its Dial-A-Ride program early next year, showcasing a comprehensive approach to sustainable transportation.

Key considerations in selecting electric vehicles include:

• Reliability based on user experiences.
• Range requirements to meet operational needs.
• Capability to power additional equipment on-site.

Despite some concerns regarding range limitations, particularly for vehicles that require on-site power, LeBeau emphasizes the importance of continued research and development in this area. The city is actively exploring solutions that align with evolving market capabilities.

Funding the transition to electric

Financial planning plays a critical role in Roseville's transition to electric vehicles. Rich Frost, transit operations supervisor, oversees the acquisition of grants aimed at supporting the city's electrification efforts. “We’re leveraging grants to fund the replacement of diesel buses and vans, as well as the development of our charging infrastructure, without tapping into general funds,” he explained.

One notable funding source is the California Energy Commission's Clean Transportation Program, which awarded a grant for the Responsive, Easy Charging Products with Dynamic Signals (REDWDS) initiative. This program is designed to facilitate the adoption of user-friendly charging solutions that can react to real-time grid signals.

Through collaboration with BetterFleet, Roseville Fleet Services is deploying an advanced electric vehicle charging management system. This platform enables:

• Real-time charge and energy management.
• Remote charger control and smart scheduling.
• Advanced reporting capabilities.

By employing machine learning algorithms, the system can accurately estimate charging times and predict vehicle ranges, enhancing operational efficiency while minimizing the impact on the power grid. Furthermore, a digital twin feature takes into account various factors such as route topography and driver behavior, allowing for data-driven operational strategies.

Expanding charging infrastructure

As Roseville continues to integrate electric vehicles into its public transit system, the necessary charging infrastructure is expanding significantly. Currently, the city boasts nine Level 3 DC fast chargers and five Level 2 chargers, with plans to enhance this capacity to a total of 71 chargers at the fleet yard during the second phase of the project.

Additionally, overhead on-route chargers are being installed at a local mall to facilitate electric bus operations. These buses will serve a new service dubbed Rapid Link, which aims to connect Roseville with neighboring cities, including a light rail station in Sacramento, thus promoting regional connectivity.

The city’s electric vehicles draw power from the community-owned Roseville Electric Utility. LeBeau emphasizes the importance of this partnership in ensuring grid reliability and cost control, allowing for scalable electrification initiatives. “Together with our suppliers and partners, we enhance our ability to operate our electric transit and city vehicles efficiently,” she stated.

Looking forward, transit operations will focus on analyzing electric vehicle driving habits to optimize performance. One area of interest is the use of regenerative braking, which can increase battery range by 25% to 30% when utilized effectively, contributing further to the sustainability of the fleet.

Reducing operational costs

The transition from clean diesel to fully electric buses is already yielding significant cost savings for the city, particularly in terms of fuel and maintenance. LeBeau noted that the city’s mechanics, numbering 16, are undergoing training in electric vehicle repairs, while five service workers are dedicated to preventive maintenance and inspections.

The shift to electric vehicles does present unique challenges, necessitating specialized training from manufacturers and the use of advanced safety equipment. However, the long-term benefits, including lower operational costs and reduced environmental impact, far outweigh these initial hurdles.

Roseville's electrification journey serves as an exemplary case study in how municipalities can effectively transition to a zero-emission fleet. With ambitious targets set for 2040 under the Innovative Clean Transit initiative and 2045 for the Advanced Clean Fleet, the city’s approach to integrating infrastructure, energy management, and vehicle readiness provides a model for other public and private sectors. This comprehensive strategy not only demonstrates commitment to sustainability but also prioritizes community health and environmental stewardship.
