EV Charging Infrastructure and Grid Capacity: Why Successful Projects Start Earlier Than You Think
Insights from Chelsea Millington-Latham, Head of Key Accounts & Customer Journey at Eclipse Power
“There’s still a misconception that EV charging projects are mainly about installing chargers,” says Chelsea Millington-Latham, Head of Key Customer & Accounts at Eclipse Power. “In reality, the biggest factor shaping delivery timelines, scalability, and long-term success is often the electrical infrastructure behind the scenes.”
Working closely with ChargePoint operators (CPOs), developers, and investors across the UK, Chelsea has seen first-hand how grid capacity is becoming one of the defining challenges in EV infrastructure rollout.
And as demand for ultra-rapid charging continues to accelerate, she believes the industry is entering a new phase – one where early collaboration and smarter infrastructure planning will separate successful projects from delayed or constrained ones.
Grid Capacity Is Now a Commercial Issue – Not Just a Technical One
As EV adoption grows, pressure to find grid capacity is increasingly challenging. and in some locations, reinforcement timelines can significantly impact programme delivery.
Chelsea says the conversation has shifted dramatically over the past few years.
“Previously, grid applications were often treated as a later-stage technical process,” she explains. “Now, they’re shaping commercial decisions from the outset – from site viability and rollout strategy through to future revenue potential.”
That shift is changing the way many operators approach infrastructure design.
Rather than building purely for immediate utilisation, more CPOs are adopting a “build-to-grow” strategy – designing charging hubs that can scale over time without requiring major redesigns or expensive upgrades later.
Chelsea says future-ready thinking is becoming essential.
“The operators moving fastest are usually the ones thinking beyond phase one,” she says. “They’re asking: what happens when utilisation doubles? What happens when vehicle charging speeds increase? How do we avoid repainting the entire site in three years’ time?”
That forward planning can include:
- Phased electricity capacity connections
- Battery energy storage systems (BESS)
- Behind-the-meter solar integration
- Smart load management systems
- Infrastructure layouts designed for future expansion
According to Chelsea, these approaches are helping operators reduce upfront costs while creating more flexibility around energisation and future growth.
Why Early Collaboration Reduces Risk For EV Projects
One of the strongest themes Chelsea sees across successful EV infrastructure projects is the value of bringing network specialists into conversations earlier.
“The earlier we’re involved, the more options customers typically have,” she explains. “Sometimes relatively small changes early in the design stage can unlock much smoother delivery later on.”
Those conversations can help identify challenges linked to:
- Grid constraints
- Land rights and easements
- Planning considerations
- Legal agreements
- Future expansion requirements
- Phased energisation opportunities
Chelsea says many avoidable delays happen because infrastructure planning begins too late in the process.
“By the time some projects reach detailed network discussions, key decisions around layout, access, or future scalability have already been fixed,” she says. “At that point, flexibility becomes much harder – and usually more expensive.”
The impact goes beyond construction timelines.
Delayed energisation can affect utilisation targets, operational revenue, customer experience, and investor confidence. Early collaboration helps create greater certainty across the entire programme.
Early EV Planning in Action
A strong example of future-ready EV infrastructure planning is the Winchester Superhub at Three Maids Hill, developed by Charge Point Operator, InstaVolt, and delivered through close collaboration between Eclipse Power and the ICP, CX Energy.
The site demonstrates how the industry is increasingly moving beyond simply installing chargers and towards creating integrated energy infrastructure. Alongside 44 ultra-rapid charging bays, the superhub incorporates 870 solar panels and 4MWh of battery storage, helping to reduce reliance on the grid while supporting high levels of charging demand.
For Chelsea, the project perfectly illustrates why infrastructure planning needs to start much earlier than many organisations expect.
“Winchester is a great example because it brings together several different initiatives in one project,” she says. “The battery storage and solar elements show how operators can think beyond the immediate connection requirement and create infrastructure that’s designed to support future growth.”
The project also highlights the value of early collaboration between charge point operators, network specialists and delivery partners. By considering grid capacity, connection design, land rights and long-term energy requirements from the outset, the team was able to develop a solution that balanced cost, flexibility and future scalability.
As demand for ultra-rapid charging continues to grow, projects such as Winchester demonstrate how integrated solutions – combining grid connections, renewable generation, battery storage and smart energy management – can help unlock larger, more resilient charging hubs for the future.
Smarter EV Charging Hubs Need Smarter Infrastructure
Chelsea also believes the industry is becoming far more sophisticated in how it thinks about energy management.
“There’s a growing recognition that you don’t necessarily need to build for every charger operating at maximum output simultaneously,” she says. “Intelligent load management is changing how sites can utilise available capacity.”
Modern ultra-rapid charging hubs are increasingly designed to dynamically balance power demand across the site in real time.
During quieter periods, chargers can operate unrestricted. During peak demand, available capacity can be shared intelligently to maintain performance while reducing strain on the network.
Where battery storage and solar generation are integrated into the design, operators gain additional flexibility while potentially reducing reinforcement requirements.
For drivers, the result is a more reliable charging experience.
For operators, it means maximising existing infrastructure more efficiently.
Future-proofing Is Becoming Essential
For Chelsea, future-proofing is no longer a “nice to have” – it’s quickly becoming fundamental to long-term EV infrastructure success.
“The pace of change in the EV sector is enormous,” she says. “Sites being designed today need to be capable of supporting future utilisation levels and charging technologies that may look very different within a few years.”
That means considering long-term scalability from the outset, including:
- Physical space for additional chargers
- Scalable electrical infrastructure
- Higher future power demand
- Flexible capacity strategies
- Battery storage and smart energy integration
Chelsea also sees collaboration across the wider industry becoming increasingly important.
“No single organisation solves these challenges alone,” she says. “The projects that progress most efficiently are usually the ones where developers, network providers, consultants, and landowners are aligned early and working toward the same outcome.”
Building EV Infrastructure for the Long Term
As the EV market matures, Chelsea believes the industry focus is shifting away from simply deploying chargers toward building resilient infrastructure platforms that can support long-term growth.
For Eclipse Power, that means helping customers navigate increasingly complex network challenges through practical collaboration, flexible connection strategies, and infrastructure designed with expansion in mind from day one.
“The projects that succeed fastest are usually the ones where everyone is aligned early,” Chelsea says. “When infrastructure is planned properly from the beginning, operators are in a much stronger position for the future.”
