Dublin Port expands reefer plug capacity

Dublin Port is expanding its refrigerated container infrastructure with a €3.4 million investment that will increase the number of powered reefer connection points available to shippers moving temperature-controlled goods. The project centres on new reefer gantries installed in the “common user area” at Alexandra Quay East, providing 140 built-in power outlets for refrigerated containers.

Reefer gantries are essentially elevated power distribution structures designed for container terminals, allowing operators to plug in stacked refrigerated units while maintaining controlled temperatures during dwell time. The new Dublin installation is positioned around high-density stacking — up to five containers high — a practical response to limited quay-side space and higher container volumes that push terminals to store more units per square metre without compromising safety or access.

The infrastructure will be operated by Doyle Shipping Group under an eight-year licence agreement. Dublin Port recorded its busiest LoLo year in 2025, with volumes up 9% on 2024, and reefer flows tend to rise fastest when food exports, retail imports, and pharmaceutical movements all compete for limited powered slots.

Alongside the gantries, a new electrical substation is being built to support the added load. That matters operationally because reefer capacity is not only a question of plug count; it is also about the reliability and redundancy of the power supply that keeps cargo within tolerance during delays, adverse weather, or vessel schedule disruption.

The cargo mix is broad. Reefers cover food exports such as dairy, meat, fish, and produce, as well as beverages and pharmaceuticals where temperature excursion can turn into scrap, insurance claims, and customer disputes. With direct EU services into Dublin increasing post-Brexit, traffic patterns have shifted, and terminals have had to adapt both infrastructure and operating plans to accommodate different arrival profiles and dwell behaviours.

Dublin Port Company framed the investment as part of a wider capacity programme. Cormac Kennedy, Head of Commercial and Programme Management Office, said, “Growth in LoLo volumes in recent years has put pressure on land use,” capturing the practical driver behind building upwards rather than outwards.

From the terminal operator’s perspective, the benefit is continuity of temperature control, even when the schedule does not cooperate. Doyle Shipping Group CEO Glen O’Connor said, “Reefer gantries supply safe, continuous electrical power to refrigerated containers during dwell time in port,” linking the upgrade directly to product protection during the least glamorous part of the journey: waiting.

For shippers, the near-term impact will be more slots and fewer workarounds, particularly during peak seasonal export periods and weather-related disruption. For the port, the investment is part of a larger pattern — adding infrastructure that supports higher-value cargo, and doing it in a way that preserves scarce land for the next constraint that arrives.
