With the rapid evolution of e-mobility, understanding the implications of increasing charging demand on distribution network infrastructure is essential, particularly in edge-of-grid regions, which often face longstanding challenges in securing a reliable electricity supply.

In recent years, the North Coast 500 (NC500), a scenic driving route spanning approximately 500 miles along the northern coast of Scotland, has grown into a major tourist attraction. Renowned for its striking landscapes and cultural landmarks, the NC500 has experienced a significant increase in visitor numbers since its launch in 2015, with a 10% rise in road traffic during the first two years and a 26% increase in footfall at popular locations along the route.

As e-mobility adoption accelerates, including electric cars, e-busses, e-bikes and emerging forms of micro-mobility, there remains an open question surrounding utilisation and reliability of the charging infrastructure in remote areas, where access is constrained by geography and existing network limitations. These challenges will not only be exacerbated by the electrification of both local heat and transport demand but also by the seasonal nature of the tourist demand. Traditional approaches to network planning, such as infrastructure reinforcement, may not be economically viable, as assets would remain underutilised for a significant portion of the year.

This paper explores the convergence of e-mobility growth, tourism and infrastructure planning in remote regions of the Scottish Highlands. It analyses segments of the NC500 on the west and north of Scotland, targeting areas with high existing charger utilisation and point-of-interest locations for public charger hub installation. A technical assessment is provided that evaluates electrical distribution system constraints at incumbent sites in these locations. When ‘better’ site services are available, whether from the perspective of tourist numbers or grid access, locational adjustments are made for infrastructure siting.

The analysis supports the development of business models and infrastructure deployment strategies that prioritise resilience and accessibility, ensuring that charging networks in remote areas can efficiently accommodate projected demand over the coming decade.
