Summary
The "Energy Study on Oeiras' Municipal Fleet" started in 2005, with the intent of gathering the data needed for a diagnosis over the fleet's energetic and environmental behaviour. The work was performed in Oeiras, coordinated by OEINERGE in partnership with the Municipality of Oeiras (CMO) and the Technical University of Lisbon (IST). The objective of the project was to perform an overview on the current performance of the fleet, and advance with proposals to implement alternative fuels, alternative propulsion and measures to reduce fuel consumption and enhance environmental behaviour.
Results
By the end of the first stage of the project, it was possible to determine the weight of each vehicle group in the total annual fuel consumption.
Although by the end of 2006 biodiesel was not yet being used in Oeiras' fleet, a superficial analysis performed by OEINERGE allowed estimating that simply by processing the existing used frying oils in the County into biodiesel, and using it to fuel some of the fleet's waste trucks, a reduction of approximately 10% in fossil fuel consumption could be achieved.
During the process of data treatment it was visible that there was a lot of data registration amiss, thus
making it impossible to calculate some indicators. Mileage had several input errors, which lead to some
non-sequential intervals. OEINERGE treated all the individual logs, correcting the existing mistakes, thus
enabling the calculation of litres/100.kilometres indicators per vehicle.
In the near future, it is expected that the quality of the information registry improves significantly, thus
permitting a thorough evaluation of the overall fleet's performance. Some of the planned actions were
impossible to realize due to the lack of some data, but it is foreseen to be accomplished in the near future.
Lessons learned and repeatability
This project constituted a major source of know-how for the technicians of the agency. It permitted to understand the full functionality of a captive fleet and identify the potential problems in its management. The work performed by OEINERGE was very well received by many institutions, which contacted the agency in order to recognize which barriers appeared along the course.
This project has been having a very important role in the dissemination of good practices in the transport sector, promoting the rational use of energy, raising awareness for the problematic of excessive fossil fuel dependency and mobilizing fleet operators - alongside citizens - to "think green". "Energy Study on Oeiras' Municipal Fleet" helped focusing attentions in the central role of waste collection trucks in municipal fleets€ management.
The colossal consumption of fuel and its weight in the Municipal budget, allied with the pressing need to keep them working makes it imperative to have a flawless data recording and monitoring. In order to replicate this project it is important to inform fleet operators that this is not an audit per se, but instead an excellent opportunity to improve their fleets' efficiency, reducing the use of fossil fuels and applying for a more sustainable behaviour.
