Scaling Investment in EV Charging Infrastructure: A Policy Roadmap for Cities
This white paper outlines strategies for city governments to accelerate the transition to electric vehicles (EVs) by fostering public-private collaboration, addressing infrastructural gaps, and implementing supportive policies. Key challenges include the lack of accessible and affordable charging options, limited grid capacity, and fragmented planning processes, which hinder widespread EV adoption. Cities worldwide are increasingly recognizing the need to integrate EV infrastructure into urban mobility frameworks to meet net-zero targets by 2050.

Strategic Planning
City governments must develop comprehensive EV strategies, including charging network expansion, land allocation, and grid compatibility. Examples like London, Paris, and Barcelona highlight the importance of setting clear targets (e.g., phasing out ICE vehicles by 2030 or 2035) and engaging stakeholders such as fleet operators, utilities, and residents. Strategic plans should balance EV infrastructure with broader mobility goals, such as reducing private vehicle use and promoting shared transport.

Standardization and Processes
Standardizing charging processes and infrastructure is critical to ensure reliability and interoperability. Regulations should mandate future-proofing, such as pre-cabling in new buildings, and streamline procurement procedures to reduce delays. Cities should also adopt open-loop, contactless payment systems to enhance user experience and attract investment. Clear guidelines for maintenance, operation, and grid connectivity are essential for creating a level playing field for operators.

Data-Driven Decision-Making
Data plays a pivotal role in identifying charging demand patterns, optimizing infrastructure layout, and informing policy. Cities should leverage data on EV ownership, traffic forecasts, and utilization rates to guide investment. Collaborating with private sectors for real-time usage data and sharing insights on future needs can build confidence among investors. Standardized data reporting ensures transparency and supports scalable planning.

Grid Capacity and Electricity Access
Expanding EV charging requires proactive grid planning, especially for high-demand areas. Cities need to prioritize grid upgrades to accommodate fast-charging stations and fleet operations. Bidirectional charging (V2G) is recommended to balance energy demand, reduce peak load, and provide economic benefits. Streamlining grid access processes and identifying ideal sites for charging infrastructure are key to reducing costs and delays.

Public-Private Collaboration
Effective collaboration with private stakeholders, including charge-point operators, utilities, and fleet managers, is crucial for scaling EV networks. Competitive public procurement processes, such as auctions and tenders, can attract investment by setting clear criteria for reliability, technical standards, and profitability. Subsidies and financial incentives, like those in France (covering up to 40% of grid upgrade costs), can alleviate economic barriers. Cities should also explore partnerships to share data and resources, ensuring equitable access to charging across residential, commercial, and public sectors.

Key Challenges and Solutions

• Land Availability: Urban space competition demands city-led identification of public land for EV infrastructure. Examples include London’s focus on land unlocking and Delhi’s citywide tenders for aggregating land.
• Infrastructure Gaps: Over 50% of city-dwelling car owners in the EU may lack home charging access, emphasizing the need for publicly accessible networks.
• Regulatory and Financial Constraints: Cities often face limitations in managing grids and funding projects. Collaborations with national governments and private investors, along with flexible subsidies, are essential for overcoming these barriers.

Case Studies

• London: £5 million funding for public chargers in boroughs lacking infrastructure boosted EV adoption and expanded the city’s charging network by 7%.
• Nottingham: A 40-unit V2G installation paired with solar and battery systems demonstrated how bidirectional charging can enhance grid resilience.
• Rotterdam: A market-driven approach, including long-term contracts and data-sharing, ensured equitable grid access and minimized investment risks.

The report underscores that cities must act as conveners, leveraging their authority to shape policies, standardize processes, and create incentives for private investment. By addressing grid capacity, data transparency, and equitable access, city governments can drive the transition to EVs while ensuring long-term sustainability and economic viability.
