Abstract
The decarbonisation of heavy duty vehicles (HDV) is increasingly recognised as a prerequisite for meeting stringent Norwegian climate targets. While the electrification of the Norwegian passenger vehicle fleet has progressed rapidly, enabled by a comprehensive charging network and favourable policy instruments, the heavy duty transport sector faces substantially more complex infrastructural and operational constraints. Transporters looking for ways to electrify their fleet are also investing in their own depot charging infrastructure. Despite this development, the need for high-power charging infrastructure along the road network seem increasingly apparent especially serving long-haul logistics. This network of charging stations needs to provide sufficient power at strategically locations to create interconnected transport corridors enabling a feasible business case of electric HDVs. The high-power requirements also necessitate much closer integration with the energy system, both at the local and regional levels. Existing planning regimes, regulatory structures and market design and incentives have not evolved at pace with these emerging demands.
The MegaCharge project seeks to address these gaps by developing high power charging technologies and facilitating coordinated action across the electric heavy duty transport value chain. A central collaboration and documentation mechanism within the project is the National Upscaling Arena, which provides a structured platform for cross sectoral dialogue, knowledge exchange and joint problem understanding between the key stakeholder groups such as grid companies, CPOs (charging point operators), OEMs (vehicle manufacturers), technology providers, industry associations, and public authorities.
This paper presents key barriers and opportunities for coordinating the deployment of high power charging infrastructure for HDVs, drawing on empirical findings from 40 semi-structured interviews and the National Upscaling Arena process. The cross sectoral empirical material reveals a set of structural and systemic barriers that collectively impede the scaling of high power charging for heavy duty transport in Norway. Grid companies underscore misalignments between ambitious electrification targets and existing planning and regulatory frameworks. Uncertain grid capacity, particularly outside urban centres, and limited incentives for proactive investment slow development, and while Conditional Connection Agreements (CCAs) offer potential, interviewees highlight the need for clearer procedures and tools, as well as stronger national coordination. CPOs face persistent challenges in securing viable sites and navigating inconsistent grid company practices. Lengthy and variable connection processes, combined with timing mismatches between grid readiness and funding schemes, create significant investment uncertainty. Operators emphasise the need for more coherent regulation, flexible tariff structures and predictable support mechanisms. Vehicle manufacturers report that electric HDVs are technologically ready for broader deployment, but uptake is constrained by insufficient reliable high power charging infrastructure. Customers demand predictable access, operational reliability and favourable total cost of ownership (TCO) conditions. Manufacturers call for clearer long term policy signals with sufficient funding support. Technology suppliers highlight that advanced solutions, such as battery energy storage systems (BESS) and digital control systems, are commercially mature but underutilised. Ambiguous regulation, weak incentives and limited cross actor coordination restrict adoption. Suppliers point to the importance of standardisation, data governance and frameworks that enable flexible grid supporting technologies.
The study identifies three overarching prerequisites for supporting a cost effective and timely roll out of high power charging infrastructure along the Norwegian road network for heavy duty transport: First, to strengthened coordination between the energy and transport sectors, supported by clearer long term planning instruments. Secondly, to accelerate the deployment of technological solutions that enhance utilisation and flexibility of existing grid capacity and finally, to improve policy instruments that facilitate investment in both infrastructure and enabling technologies while ensuring predictable operating conditions for transport operators.
