Powering ports through smarter planning

For ports pursuing decarbonisation, electrification has become far more than an engineering challenge. As shore power, electric cargo handling equipment and batterypowered vehicle fleets become increasingly commonplace, operators must also rethink how energy is generated, distributed and managed if they are to avoid creating a new generation of operational bottlenecks.

“The more credible and emerging model is that of the port as a grid-connected microgrid or multi-energy hub, where local generation, storage and advanced energy management systems collectively reduce reliance on external supply while maintaining resilience through grid connectivity,” says Dr Thomas Beard, Clean Maritime/Alternative Fuels Lead at BMT.

“Electrification of shore power, cargo handling equipment and transport fleets significantly increases demand but also enables it to be controlled and optimised digitally, allowing energy to become an operational variable alongside logistics.”

A shift in thinking

That shift in thinking underpins a wider transformation taking place across the ports sector. Rather than viewing electrification as a series of individual infrastructure projects, Dr Beard and BMT Electrical Capability Lead, Tania Berry, argue that ports must begin treating energy as a core operational resource, planned and managed alongside vessel movements, cargo flows and landside logistics.

Ms Berry believes this requires ports to move beyond simply asking how much electrical capacity they need. Instead, operators should first understand how energy demand is likely to evolve across every aspect of the business.

In her paper Electrification as the New Baseline: Re-defining the Role of Ports in a Decarbonised Supply Chain, she argues that infrastructure readiness begins with establishing a comprehensive baseline covering existing electrical networks, substations, transformers, quay-side power provision, cargo handling equipment and digital control systems before major investment decisions are made.

The paper sets out a structured framework for port planning, beginning with infrastructure assessment and progressing through electrical load forecasting, technical and commercial feasibility studies, phased implementation and continuous performance monitoring. Rather than representing isolated engineering exercises, these stages collectively form the foundation of a resilient electrification strategy capable of adapting as operational demands change. The importance of that planning becomes even more apparent as ports confront growing pressure on electricity networks.

“Ports can electrify critical infrastructure despite being constrained by grid capacity, but doing so requires a fundamental shift from viewing the grid as the primary energy source to treating it as just one component, or node if you like, within a broader integrated energy system,” Ms Berry explains.

A flexible approach For many ports, traditional grid reinforcement alone is unlikely to provide the answer. National electricity networks are themselves under increasing pressure, meaning lengthy and expensive upgrades cannot always keep pace with decarbonisation ambitions.

Instead, Dr Beard and Ms Berry advocate a more flexible approach, combining local renewable generation, battery storage, demand-side management and digital control technologies to reduce dependence on external electricity supplies while improving operational resilience.

“Microgrids are rapidly shifting from an optional innovation to an operational necessity because they enable ports to balance supply and demand internally, reducing peak load dependence on constrained grid connections, when coupled with energy generation and especially storage,”

Dr Beard says. “By integrating on-site renewable generation, battery storage, and intelligent energy management systems, microgrids allow ports to ‘flatten’ demand profiles, store energy when it is abundant, and deploy it during peak operational periods such as simultaneous vessel berthing or high cargo handling and delivery.”

Ms Berry’s research reinforces the argument that microgrids should not be viewed in isolation but as part of a broader energy architecture. Modern ports are evolving into integrated multienergy systems where renewable generation, battery storage, digital control platforms and conventional grid connections
work together. Within that environment, sophisticated energy management systems become essential for balancing fluctuating demand while maintaining operational performance.

The paper argues that successful port infrastructure projects increasingly depend upon detailed engineering analysis long before construction begins. Multi-scenario electrical load models should account for berth occupancy, cargo growth, charging behaviour, seasonal variations and future expansion plans, enabling operators to understand where capacity constraints are most likely to emerge and how they can be mitigated before they affect operations.

Yet while large gateway ports often dominate discussions around electrification, Ms Berry believes smaller ports and terminals face an equally important challenge.

“A commercially viable electrification roadmap for smaller ports and terminals with limited CAPEX budgets is not built on large, upfront infrastructure transformation, but on a phased, data-led approach that prioritises quick wins, operational efficiency and scalable investment aligned to demand growth,” she says.

“There is no one-size-fits-all solution, particularly for smaller ports, where financial constraints and operational diversity require tailored, incremental strategies.”

That philosophy aligns closely with BMT’s emphasis on modular infrastructure. Rather than installing systems sized for decades of future demand, ports can adopt a “build-as-you-grow” approach, introducing battery storage, charging infrastructure, substations and renewable generation in phases. Supported by detailed operational data and continuous monitoring, this allows investment to expand alongside demand while reducing financial risk and avoiding
unnecessary upgrades.

Intelligent planning

For both experts, the message is clear: Successful port electrification is no longer defined by the volume of electrical equipment installed. Instead, competitive advantage will increasingly depend on how intelligently ports plan, integrate and manage the energy systems that underpin their future
operations.

While planning provides the foundation, Dr Beard and Ms Berry argue that long-term success will ultimately depend on how effectively ports manage electricity once assets are electrified. As more cranes, vehicles, shore power connections and storage facilities come online, energy itself becomes an
operational resource that must be managed with the same precision as cargo movements or berth allocation.

“As ports electrify cranes, vehicles, shore power and storage simultaneously, the risk of creating new operational bottlenecks and energy-demand peaks becomes a system level challenge rather than a purely electrical one,” Dr Beard explains.

“These risks arise when infrastructure upgrades are not matched by integrated operational planning and energy management.”

The challenge, he says, is not simply installing sufficient electrical capacity but understanding when, where and how that capacity will be used. Time-series load forecasting, scenario-based modelling and analysis of berth schedules, cargo handling cycles and charging behaviours enable operators to anticipate periods of peak demand before they become operational constraints. Ms Berry’s paper places this system-level thinking at the heart of modern port planning.

Rather than considering electrical infrastructure, cargo operations and digital systems independently, she argues they must be designed as an integrated whole.

Without that integrated modelling framework, investments risk becoming inefficient while exposing operators to unnecessary operational and regulatory risk.

Intelligent energy management

This is where intelligent energy management systems become indispensable.

“The deployment of digital energy management systems (EMS) and SCADA-enabled monitoring enables real-time balancing of loads across port assets, allowing operators to actively smooth demand profiles and prioritise critical operations,” Ms Berry says.

“Rather than electrifying assets independently, ports should treat themselves as integrated multi-energy systems, where infrastructure, operations, and energy flows are tightly coupled and dynamically optimised to prevent localised
overloads and delays.”

Ms Berry expands on that concept by describing digitalisation as the mechanism that links engineering with day-to-day operations. Energy management systems, supervisory control and data acquisition (SCADA), load monitoring and submetering provide operators with continuous visibility of
electrical demand, allowing forecasts to be validated against real-world performance while identifying opportunities to improve efficiency as electrification expands.

Continuous monitoring also creates a feedback loop that extends well beyond project completion. Rather than viewing electrification as a one-off capital
programme, Ms Berry argues that ports should continually reassess electrical loads, infrastructure performance, emissions reductions and operational efficiency to ensure systems remain aligned with future growth.

As additional shore power installations, electric cargo handling equipment and charging infrastructure are introduced, this iterative approach enables operators to optimise performance while delaying or avoiding costly infrastructure upgrades.

The wider implications

For Dr Beard, the wider objective is resilience.

“Operationally, this transforms the port into a real-time energy system, where berth allocation, equipment scheduling and charging strategies are increasingly aligned with energy availability, and where batteries support peak shaving, ridethrough and power quality stabilisation,” he says.

“In this context, ‘energy independence’ is best understood not as total disconnection from the grid, but as the ability to meet a substantial proportion of demand locally and to operate autonomously when required, enhancing resilience, reducing operating costs and strengthening the port’s role as a critical enabler of a decarbonised supply chain.”

That distinction is important. Dr Beard is not advocating complete independence from national electricity networks but a more resilient operating model in which ports reduce their dependence on external supply through local generation, battery storage and intelligent control. Grid connectivity remains essential, but increasingly forms just one component of a broader, more flexible energy architecture.

Ultimately, both experts return to the same central message. The future will not belong simply to the ports that install the most chargers, the largest substations or the greatest renewable generation capacity. Competitive advantage will increasingly favour operators that understand how every element of port infrastructure, energy management and port planning works together as part of a single operational system.
