Project Highlights

  • Energetics reviewed the City of Raleigh's fleet operations and developed an implementation plan to increase the use of alternative fuel vehicles in the City’s fleet of more than 1,900 vehicles.
  • Through Energetics’ recommendations, alternative fuel and/or hybrid vehicles would replace conventionally fueled vehicles in certain vehicle classes or functions when the vehicles have reached the optimal life cycle. 

The City of Raleigh is working to lower emissions and operating costs generated by the City’s vehicle fleet. The first step involved a comprehensive examination of the full vehicle life cycle to determine the optimal replacement life cycle, i.e., when to retire, repair, or replace vehicles in favor of more efficient and cleaner alternatives. The findings provided a decision support system to measure the existing performance and operating cost of individual vehicles to determine when to replace a vehicle, maintaining the optimal life cycle of the existing asset while minimizing overall emissions.

With the support of CST Fleet Services and the North Carolina Clean Energy Technology Center, the Energetics team collected reports and data to analyze current fleet practices, assess fueling infrastructure, and review fleet policies. A survey of the City of Raleigh fleet personnel was conducted to gather feedback on the fuel and fleet implementation activities to date. Existing fleet operations, practices, and initiatives were evaluated by conducting a review of the fuel and fleet systems, followed by analysis of the City’s best management practices.

Recommendations were developed in support of the City’s path towards reaching its fossil fuel and greenhouse gas reduction goals. Energetics provided potential solutions to improve infrastructure, performance metrics and measures, a vehicle replacement strategy, purchasing policies for new equipment, and the foundation for a realistic fossil fuel reduction policy. The resulting Fuel and Fleet Transformation Plan guides the City through an effective transition to using more alternative fuels and advanced transportation technologies.
