In response to these challenges, WSP has adopted a dual approach to e-mobility projects, encompassing both greenfield masterplan projects and developments within existing cities.
For greenfield projects, such as those under the Saudi Public Investment Fund’s umbrella, the reliance on a shared fleet of electric vehicles necessitates a planning approach similar to that used for electric public transport systems. This involves calculating the required number and type of chargers based on anticipated vehicle usage levels. Consideration of the 'downtime' of charging is also crucial, requiring infrastructure at both depots and en route to ensure smooth operations. Catering to a variety of users and journey types, including staff travel, taxi services, public transit, private vehicles, and service vehicles, is essential for the accuracy of this planning approach.
In contrast, our approach for existing urban areas takes into account personal mobility (cars, e-bikes) and public transport. This involves examining key factors affecting usage predictability, such as identifying current and future EV users, determining the level of service we are willing to provide to EV users, assessing the capacity and scalability of power substations, and understanding travel patterns and charging behaviors. We also leverage the gradual accumulation of regional data while incorporating ongoing feedback to refine our predictions and improve our ability to accurately forecast EV infrastructure needs.
