Case study: EVs & charging ecosystems — a leading company's implementation and lessons learned

BP's decision to rebrand its UK charging infrastructure under the bp pulse banner and invest over £1 billion in rapid and ultra-rapid charging hubs between 2021 and 2025 represented one of the most ambitious EV charging deployments by a legacy energy company globally. By the end of 2025, bp pulse operated more than 27,000 charge points worldwide, with over 9,000 across the United Kingdom, making it one of the largest public charging networks in the country. The scale of this rollout, and the operational challenges encountered along the way, offers concrete lessons for sustainability leads, fleet managers, and infrastructure planners navigating the transition to electric mobility.

Why It Matters

The United Kingdom has committed to ending the sale of new petrol and diesel cars by 2035, and EV registrations have grown from 11% of new car sales in 2022 to over 28% in 2025 according to the Society of Motor Manufacturers and Traders (SMMT, 2025). However, public charging infrastructure has not kept pace with vehicle adoption. The Competition and Markets Authority identified a "postcode lottery" in charging availability, with London and the South East accounting for over 40% of all public charge points while large areas of the Midlands, North, and rural Wales had fewer than 5 rapid chargers per 100,000 residents (CMA, 2024). This infrastructure gap threatens to slow EV adoption in precisely the regions where driving distances are longest and public transport alternatives are fewest. Companies like bp pulse that can deploy reliable, high-powered charging at scale play a critical role in bridging that gap.

The financial opportunity is substantial. McKinsey estimates the European EV charging market will reach £20 billion in annual revenue by 2030, with margins improving as utilisation rates climb above the 15 to 20% threshold where most networks currently operate (McKinsey, 2025). For bp, the charging business also serves a strategic hedge against declining fossil fuel demand, repositioning an oil and gas major as an integrated energy company.

Key Concepts

Hub-and-spoke deployment model: Rather than scattering individual chargers across thousands of locations, bp pulse concentrated investment in charging hubs: dedicated sites with 6 to 20 ultra-rapid chargers (150 to 300 kW) located at high-traffic destinations. This model reduces per-unit installation costs by 25 to 35% through shared grid connections, trenching, and site preparation. The company's flagship hub at NEC Birmingham features 16 ultra-rapid chargers capable of adding 100 miles of range in approximately 10 minutes.

Grid connection as the binding constraint: In the UK, securing a new high-voltage grid connection from the local distribution network operator (DNO) can take 12 to 36 months and cost £100,000 to £1 million depending on required transformer and cable upgrades. bp pulse found that grid connection timelines, not planning permission or site acquisition, determined the speed of its rollout. The company responded by co-locating charging hubs at its existing petrol station forecourts where high-voltage grid connections were already in place, reducing connection timelines from an average of 18 months to 3 to 6 months.

Dynamic pricing and demand management: bp pulse implemented time-of-use pricing that varies charging costs by 15 to 30% between peak and off-peak periods. The company reported that dynamic pricing shifted approximately 12% of charging sessions from peak (5 PM to 8 PM) to off-peak hours (10 PM to 6 AM), reducing demand charges that accounted for up to 40% of electricity costs at high-utilisation sites.

What's Working

BP pulse's forecourt conversion strategy has proven highly effective at accelerating deployment. By retrofitting existing petrol stations with ultra-rapid chargers, the company avoided the two largest cost and time barriers: land acquisition and grid connections. The company converted over 300 UK forecourt sites by the end of 2025, with average installation timelines of 14 weeks from design to energisation, compared to 40 to 60 weeks for greenfield hub sites (bp pulse, 2025).

The hub model also delivered superior customer experience metrics. Sites with 8 or more chargers achieved average wait times below 5 minutes even during peak periods, compared to 15 to 25 minutes at sites with only 2 to 4 chargers. Customer satisfaction scores at hub locations averaged 4.2 out of 5 on the bp pulse app, versus 3.4 at smaller installations. Reliability rates at hubs exceeded 95% uptime, partly because on-site staff at forecourts could perform basic troubleshooting (clearing screen errors, resetting connections) that would otherwise require a field service visit (bp pulse, 2025).

Shell Recharge, bp pulse's closest UK competitor, pursued a different but complementary approach by partnering with destination venues including shopping centres, supermarkets, and leisure facilities. Shell's partnership with Waitrose to install chargers at 100 supermarket locations demonstrated that dwell-time charging at 50 to 75 kW can achieve higher utilisation rates (22 to 28%) than rapid hubs at motorway service areas (14 to 18%), because drivers charge while shopping rather than making dedicated charging stops. The two approaches together are shaping a UK charging landscape where rapid hubs serve en-route highway needs and destination chargers serve daily convenience charging (Shell Recharge, 2025).

Tesla's Supercharger network, which opened to non-Tesla vehicles in the UK in 2023, provided a third instructive model. Tesla achieved the highest reliability rate among UK networks at 98.5% uptime, largely attributable to its vertically integrated approach: Tesla designs its own chargers, power electronics, and software, enabling remote diagnostics and over-the-air firmware updates that resolve approximately 60% of faults without a site visit (Zap-Map, 2025).

What's Not Working

Interoperability remains a persistent friction point. Despite the UK's adoption of CCS (Combined Charging System) as the standard connector, bp pulse and other networks have experienced payment system fragmentation. A 2025 Zap-Map survey found that 34% of EV drivers had experienced a failed payment transaction at a public charger in the previous month, most commonly due to contactless card reader failures or app authentication errors. The UK government's Public Charge Point Regulations 2023 mandate contactless payment at all new rapid chargers above 8 kW, but legacy installations remain app-only, creating confusion for occasional users (Zap-Map, 2025).

Rural and suburban coverage gaps have proven resistant to market-led investment. bp pulse's internal analysis found that charging hubs in rural areas with fewer than 10,000 residents typically achieve utilisation rates of 5 to 8%, well below the 12 to 15% breakeven threshold. The company has largely avoided these locations, concentrating deployment in urban centres and motorway corridors where utilisation supports commercial returns. The UK government's Local Electric Vehicle Infrastructure (LEVI) fund, allocating £381 million to local authorities for charging in underserved areas, has been slow to disburse: by mid-2025, only 23% of LEVI funds had been contracted, with councils citing procurement complexity and DNO engagement difficulties as primary barriers (Office for Zero Emission Vehicles, 2025).

Grid capacity constraints have forced delays or downsizing at multiple planned hub sites. In parts of south-east England and the M4 corridor, DNOs have exhausted available transformer capacity, requiring substation upgrades with 24 to 36 month lead times before new high-power connections can be energised. bp pulse reported that 15% of its 2024 planned installations were delayed by more than 6 months due to grid constraints, with 5% requiring complete site relocation (bp pulse, 2025).

FAQ

Q: How long does it take to convert an existing petrol station forecourt to include EV charging? A: bp pulse's experience indicates 14 weeks on average from design approval to energisation when the site has an existing high-voltage grid connection. Key steps include electrical design and DNO notification (2 to 3 weeks), civil works including trenching and foundation installation (4 to 5 weeks), charger hardware installation and commissioning (3 to 4 weeks), and DNO inspection and connection (2 to 3 weeks). Forecourt conversions that require grid connection upgrades add 6 to 18 months to the timeline depending on the scope of works required by the DNO.

Q: What utilisation rate is needed for a charging hub to break even financially? A: The breakeven utilisation rate depends on electricity costs, demand charges, hardware amortisation, and pricing strategy. bp pulse's UK network data suggests that ultra-rapid hubs (150 to 300 kW) require 12 to 15% average utilisation to cover operating costs including electricity, maintenance, payment processing, and network software. Achieving a positive return on the capital investment typically requires sustained utilisation above 18 to 22% over the asset's 10 to 15 year life. Sites in urban centres and major motorway corridors generally reach breakeven within 2 to 3 years, while suburban locations may take 4 to 6 years.

Q: How can fleet managers evaluate whether to install depot charging or rely on public networks? A: The decision hinges on fleet size, daily mileage, and depot electrical capacity. Fleets with more than 20 vehicles operating predictable routes typically achieve lower total cost of ownership with depot overnight charging at 7 to 22 kW, where electricity costs are £0.08 to £0.15 per kWh versus £0.45 to £0.79 per kWh at public rapid chargers. However, depot charging requires sufficient grid capacity (a 50-vehicle fleet charging overnight draws 150 to 350 kW) and may require DNO reinforcement. A hybrid strategy using depot charging for 80% of energy needs and public rapid charging for on-route top-ups typically optimises cost and operational flexibility.

Q: What is the biggest risk to charging network profitability in the UK? A: Demand charges represent the largest and most unpredictable cost risk. UK electricity tariffs for commercial users include capacity charges based on peak demand (measured in kVA), which can constitute 30 to 45% of a hub's total electricity bill. A 10-charger hub drawing 2 MW at peak incurs demand charges of £3,000 to £6,000 per month even if average utilisation is low. On-site battery storage (200 to 500 kWh) can reduce peak demand by 30 to 50% through load-shifting, with typical payback periods of 4 to 7 years at current battery costs.
