A Port member of PIN is working to increase the share of renewable energy in its energy mix while improving how clean energy is generated, stored, distributed, and managed across maritime, logistics, and industrial activities.
Ports are rapidly becoming complex energy ecosystems. Electrified cargo-handling equipment, electric mobility, and Onshore Power Supply (OPS) can create highly variable, high-power demand profiles that port’s legacy electrical architectures were not designed to handle. In parallel, on-site renewables (notably solar PV and potentially wind where feasible) introduce variability, forecasting uncertainty and a production available not on demand but depending on external condition. External grid conditions can also become more constrained during peak periods, increasing the value of local flexibility.
This challenge focuses on solutions that help a port operate an energy system that is resilient, efficient, cyber-secure, and optimizable in real time, supporting a long-term ambition as a goal to gain energy independence while reducing emissions. without defining a timeline and without any binding promises.
Why Do Ports Struggle With Renewables at Scale? The Challenges
Ports are dense, safety-critical industrial environments where energy demand can shift minute-by-minute. When electrification and renewables scale simultaneously, common friction points include:
- Intermittency vs. operational demand: Variable renewable output must align with continuous operations and high-power services such as OPS.
- Peak-load events and simultaneity: Concurrent OPS connections, charging cycles, and heavy equipment operation can create short-duration peaks that stress transformers, feeders, and contractual capacity limits if not actively managed.
- Power quality and stability: Sensitive equipment may be impacted by voltage dips, harmonics, and fast load ramps, issues that can intensify with high inverter penetration and large, sudden load steps.
- Legacy grid design constraints: Many port electrical systems were built for one-way delivery from the external grid, not for distributed generation, storage, bidirectional power flows, and microgrid operation.
- Data fragmentation: Energy data may sit across multiple meters, tenants, terminals, and systems, limiting the ability to forecast, coordinate, and optimize.
- Space: The primary use of land in a port area should remain logistics-related; therefore, renewable energy projects should make use of spaces that are not suitable for goods handling.
- Permitting, and operational disruption: Deploying PV, storage, substations, cabling, and protection systems must fit within constrained areas and strict safety zones while minimizing impact on throughput.
The Constraints: Why It’s Not a Simple Fix
Solutions must be deployable under real port conditions. Key constraints include:
- Operational continuity: No reduction in berth productivity, yard throughput, or safety performance during deployment, commissioning, and routine operation.
- Harsh environment resilience: Equipment must tolerate humidity, corrosion, vibration, dust, and demanding maintenance realities typical of port areas.
- Safety and compliance: High-voltage systems, storage installations, and any hazardous-area interfaces must align with port procedures and industrial safety requirements (including emergency response and isolation procedures).
- Interoperability with OT/IT: Integration with existing metering, SCADA/EMS, terminal operations systems, and scheduling/asset systems should be practical and secure, preferably via standard industrial protocols/APIs.
- Cybersecurity: Increased connectivity expands the attack surface; solutions must be designed for critical infrastructure environments (segmentation, secure authentication, auditing, and resilience to degraded comms).
- Scalability under uncertainty: OPS uptake and equipment electrification may grow unevenly; architectures should be modular, extensible, and able to deliver value in phases.
Glimmers of Hope: New Technologies on the Horizon?
The port is interested in solutions that move beyond “more generation” to smart energy management. Examples include:
Advanced forecasting + predictive control
- Forecasting that combines weather inputs with operational signals (e.g., expected OPS demand, vessel call patterns, equipment duty cycles) to anticipate peaks and renewable variability.
- Model-predictive control approaches to schedule storage dispatch, flexible charging, and controllable loads proactively rather than reactively.
Microgrid optimization and flexibility
- Microgrid control strategies to balance local generation, storage, and priority loads while coordinating with the external grid.
- Islanding-ready architectures (where appropriate) to maintain critical services during upstream disturbances.
Storage architectures fit for ports
- Storage for peak shaving, ramp-rate control, and fast balancing, with safety-first design (thermal management, containment, monitoring) showing large energy density and long service life
- Hybrid flexibility approaches (e.g., combining batteries with controllable demand or other flexible assets) where operationally relevant.
Digital twins and decision support
- Simulation tooling to evaluate upgrade paths, quantify bottlenecks, test operational strategies, and support phased investment planning under realistic constraints and adoption scenarios.
Space-efficient renewable deployment
- Approaches using-traditional surfaces (rooftops, parking structures, logistics buildings, barriers) and concepts suitable for constrained industrial zones.
- Approaches that use new technologies (such as walkable PV or lightweight PV with specialised grips) which enable the use of non-traditional surfaces such as embankments and pedestrian access areas as well as the use of barriers that allow for wave power generation
Integration: Making It Happen
High-value solutions are those that combine technical performance with practical deployment:
- End-to-end visibility across generation, storage, substations, and the highest-impact loads (OPS, charging hubs, cranes/handling equipment, buildings).
- Load prioritization and coordination to manage flexible charging and shiftable loads while protecting operational continuity and safety.
- Performance monitoring with clear KPIs (energy cost, self-consumption rate, peak reduction, curtailment reduction, power quality events, availability, resilience metrics).
- Secure interfaces to exchange data with port operational systems and relevant external stakeholders, with security-by-design and clear governance of data ownership/access.
- Phased deployment that can start with “monitor + optimize” and expand to “control + dispatch” as readiness increases.
The Future is Smarter (and Cleaner
The target state is a port that can maximize renewable self-consumption, reduce peak stress and curtailment, and coordinate electrified services without compromising safety or throughput—supporting long-term emissions reduction through scalable operational and infrastructure improvements.
