# Shore Power: Sales Work for Port Suppliers > Shore power creates equipment, adaptor and service sales for port suppliers. See who buys, when to make contact and why bulk terminals come next. URL: https://vesselreach.si/blog/shore-power-sales-work-for-port-suppliers | Published: 2026-11-07 | Guide | Topic: Carrier service and surcharge changes ## In short Shore power is grid electricity a berthed ship draws through a cable instead of running auxiliary engines, and it creates supplier sales work in connection hardware, adaptors, cable management, commissioning and maintenance. A 2024 IEEE Electrification Magazine study found bulk carriers needing high-voltage connections account for up to 68% of emissions in that group, making busy bulk terminals the first serious buying conversations. ## Key takeaways - Shore power sales work covers connection hardware, adaptors, cable handling, commissioning support and lifetime maintenance and spares. - A 2024 IEEE Electrification Magazine study found high-voltage bulk carriers account for up to 68% of emissions in that group. - Technical superintendents own ship-side compatibility, purchasing superintendents at the DOC holder hold the budget, port engineers buy quay-side hardware. - Contact the owner, manager or technical manager while the vessel is still at sea, before the electrician is booked. - A charging window changes the agent's schedule and the port disbursement account, so plan the call around the connection sequence. ## At a glance - **What: What is shore power?** Electricity a berthed ship draws from the quay instead of its auxiliary engines, delivered through converters, transformers, plugs and interconnectors with a charging energy management system. ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2020.3005699)) - **Who: Who is pushing shore power forward?** Governments and research bodies. Norway awarded USD 44 million in grants to advance battery-powered ships, The Maritime Executive reported in November 2026. ([The Maritime Executive](https://maritime-executive.com/article/norway-awards-44m-in-grants-to-advance-battery-powered-ships)) - **Where: Where is shore power being tested?** The Port of Aarhus completed tests on Denmark's first shore power for containerships with a trial docking, according to The Maritime Executive in October 2026. ([The Maritime Executive](https://maritime-executive.com/article/aarhus-tests-denmark-s-first-shore-power-for-containerships)) - **When: When did the largest battery-electric ship enter service?** The China Zorrilla began commercial service on the River Plate for Buquebus in October 2026, gCaptain reported. ([gCaptain](https://gcaptain.com/worlds-largest-battery-electric-ship-begins-commercial-service-in-south-america/)) - **Why: Why is shore power expanding now?** A 2024 study in IEEE Electrification Magazine found bulk carriers needing high-voltage connections account for up to 68% of emissions in that group, driving standardisation work. ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2024.3473334)) - **How: How is the technology developing?** A 2022 paper in Energies presents a bidirectional modular converter that harvests renewable energy and controls power flow for shore power systems at ports. ([Energies (Multidisciplinary Digital Publishing Institute)](https://doi.org/10.3390/en16010274)) Shore power is grid electricity a ship draws at berth through a cable instead of running its own auxiliary engines. For port suppliers it is a new sales line: the connection hardware, the adaptors, the cable handling and the people who keep the system working. ## What shore power involves at the berth A shore connection is a chain of equipment, not a single plug. A 2020 review in IEEE Electrification Magazine describes the charging path from shore to the onboard battery as power electronics converters, transformers and passive elements, plugs and interconnectors, plus a charging energy management system ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2020.3005699)). The same paper compares alternating current, direct current and wireless solutions and discusses where each applies. That matters commercially because a supplier quoting a "shore power cable" without knowing the ship's system is quoting half a job. A 2015 tutorial in Proceedings of the IEEE sets out the high-voltage shore connection, or HVSC (a high-voltage link between quay and ship), including shore transformers and converters, onboard cubicles and shore switchboards, and the operating sequence for connecting and disconnecting ([Proceedings of the IEEE](https://doi.org/10.1109/jproc.2015.2491647)). ## Why bulk carriers are the next sales target Container and ferry berths get the attention, but the standardisation work is moving towards dry bulk. A 2024 study in IEEE Electrification Magazine examined shore power standardisation for bulk carriers and general cargo ships and found that bulk carriers needing a high-voltage connection account for up to 68% of greenhouse gas emissions in that group ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2024.3473334)). The paper also examined berth usage and suggested that equipping the most frequently used terminals with a cable management system would speed up global deployment. Read commercially, the busiest bulk terminals are where the first serious purchasing conversations will happen. - **Technical superintendents** own the ship-side compatibility question. - **Purchasing superintendents** at the DOC holder (the company holding the ship's Document of Compliance) hold the budget line. - **Port engineers and terminal operators** buy the quay-side hardware. ## What the news flow is telling suppliers Activity is spreading beyond the North Sea. The Port of Aarhus completed tests on Denmark's first shore power for containerships with a trial docking, according to The Maritime Executive (October 2026) ([The Maritime Executive](https://maritime-executive.com/article/aarhus-tests-denmark-s-first-shore-power-for-containerships)). [Battery-electric tonnage is entering service](https://vesselreach.si/blog/battery-powered-ships-port-call-work-from-norways-grants), which creates repeat callers with a predictable charging need. The world's largest battery-electric ship, the China Zorrilla, began commercial service on the River Plate for Buquebus, gCaptain reported in October 2026 ([gCaptain](https://gcaptain.com/worlds-largest-battery-electric-ship-begins-commercial-service-in-south-america/)). The Maritime Executive described the same vessel as the world's biggest battery-electric ferry entering commercial service ([The Maritime Executive](https://maritime-executive.com/article/world-s-biggest-battery-electric-ferry-enters-commercial-service)). Government money is behind the trend. Norway awarded USD 44 million in grants to advance battery-powered ships, The Maritime Executive reported in November 2026 ([The Maritime Executive](https://maritime-executive.com/article/norway-awards-44m-in-grants-to-advance-battery-powered-ships)). The Maritime and Port Authority of Singapore, the Research Council of Norway and the Singapore Maritime Institute have launched a joint research grant call on greener shipping, MarineLink reported in November 2026 ([MarineLink](https://www.marinelink.com/news/singapore-norway-launch-call-green-544177)). The grid side is changing too. A 2022 paper in Energies presents a bidirectional modular converter that can harvest renewable energy, control power flow and support shore power systems at ports ([Energies](https://doi.org/10.3390/en16010274)). A 2026 review in EcoEnergy examines vessel-to-grid charging and identifies infrastructure requirements and grid compatibility among the key challenges ([EcoEnergy](https://doi.org/10.1002/ece2.70068)). ## The supplier work that follows Shore power creates several distinct sales conversations, and they rarely sit with the same buyer. 1. **Connection hardware and adaptors.** Plugs and interconnectors differ between ships, so a chandler stocking adaptors needs to know which systems call at its berths. 2. **Cable management.** The 2024 standardisation study links cable management systems at busy terminals to faster deployment ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2024.3473334)). 3. **Testing and commissioning support.** New installations need technicians, tools and consumables during commissioning. 4. **Maintenance and spares.** Converters, switchboards and connectors need service through the life of the berth. 5. **Husbandry around the call.** A charging window changes the PDA (port disbursement account, the pro-forma of port costs) and the agent's schedule. The 2015 Proceedings of the IEEE tutorial also raises bonding, cathodic protection interaction and electrical safety in port facilities ([Proceedings of the IEEE](https://doi.org/10.1109/jproc.2015.2491647)). Those are technical questions a supplier can use to open a conversation with a technical superintendent rather than a purchasing clerk. ## Who to contact, and when Timing decides whether a supplier wins the call or reads about it later. Reach the decision-maker while the vessel is still at sea, not after it is alongside and the electrician has already been booked. - Start with the company behind the vessel: owner, manager or technical manager. - Then the role that owns the budget: technical superintendent for compatibility, purchasing superintendent for the order. - Then the terminal or port engineer for quay-side equipment. For a wider view of how early contact changes outcomes, see [vessel arrival timing and why days before port matter](https://vesselreach.si/blog/vessel-arrival-timing-why-days-before-port-matter). ## How VesselReach helps Shore power work starts with knowing which ships are coming and who decides. VesselReach, built by CatalystIQ, detects vessels near your selected ports and those scheduled or expected to arrive, so you can act before the ETA. - **AI company targeting** identifies the owner, manager or operator behind each vessel, which means you approach the right company rather than a generic inbox. - **Decision-maker discovery** finds technical superintendents, purchasing superintendents and port operations roles, which means your shore power pitch reaches the person who owns the question. - **Multichannel outreach** runs staged email, WhatsApp and phone contact with automated follow-ups, which means no lead goes cold while the vessel is still at sea. Book a VesselReach demo to see which vessels are heading for your berths and who to contact first. ## Key facts - According to a 2024 study in IEEE Electrification Magazine, bulk carriers needing a high-voltage shore connection account for up to 68% of greenhouse gas emissions in the bulk carrier and general cargo ship group.

Shore power is grid electricity a ship draws at berth through a cable instead of running its own auxiliary engines. A 2020 review in IEEE Electrification Magazine describes the connection path as power electronics converters, transformers, plugs and interconnectors, plus a charging energy management system. ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2020.3005699)) ### What is a high-voltage shore connection (HVSC)? A high-voltage shore connection is a high-voltage link between quay and ship. A 2015 tutorial in Proceedings of the IEEE sets out the HVSC chain: shore transformers and converters, onboard cubicles and shore switchboards, plus the operating sequence for connecting and disconnecting. ([Proceedings of the IEEE (Institute of Electrical and Electronics Engineers)](https://doi.org/10.1109/jproc.2015.2491647)) ### Which ships need high-voltage shore connections? Bulk carriers are the next target. A 2024 study in IEEE Electrification Magazine found that bulk carriers needing a high-voltage connection account for up to 68% of greenhouse gas emissions in the bulk and general cargo group, which is why standardisation work is focused there. ([IEEE Electrification Magazine](https://doi.org/10.1109/mele.2024.3473334)) ### Are ports outside Europe installing shore power? Yes. The Port of Aarhus completed tests on Denmark's first shore power for containerships, The Maritime Executive reported in October 2026, and the battery-electric ship China Zorrilla began commercial service on the River Plate for Buquebus, gCaptain reported in October 2026. ([The Maritime Executive](https://maritime-executive.com/article/aarhus-tests-denmark-s-first-shore-power-for-containerships)) ### What shore power work can a ship chandler sell? A ship chandler can sell connection hardware and adaptors, cable management equipment, testing and commissioning support, and maintenance and spares for converters, switchboards and connectors. Plugs and interconnectors differ between ships, so a chandler needs to know which systems call at its berths. ### How can a port supplier find ships that will need shore power? Track vessels scheduled or expected to arrive at the ports you serve, identify the owner or manager behind each vessel, and contact the technical or purchasing superintendent before the vessel berths. VesselReach, built by CatalystIQ, runs this in one workflow. ## Sources 1.

A 2020 review in IEEE Electrification Magazine sets out the equipment chain, and a 2024 study found bulk carriers needing high-voltage connections account for up to 68% of emissions in that group. Norway's USD 44 million in battery-ship grants and the Port of Aarhus containership tests show the work spreading. The practical step is to identify vessels due at your berths and contact the technical or purchasing superintendent before the ETA. Who buys shore power equipment at a port? Port engineers and terminal operators buy the quay-side hardware, technical superintendents own ship-side compatibility, and purchasing superintendents at the DOC holder hold the budget line. When should a supplier make contact? While the vessel is still at sea, before the electrician is booked; start with the owner, manager or technical manager behind the ship. What does a charging window change for a port agent? It changes the schedule and the port disbursement account, so the call is planned around the connection sequence. Shore power is a chain of equipment, not a single plug, so a supplier quoting a cable without knowing the ship's system is quoting half a job. The first serious purchasing conversations will happen at the busiest bulk terminals, where a 2024 study in IEEE Electrification Magazine found high-voltage bulk carriers account for up to 68% of emissions in that group. Timing decides the call: reach the technical or purchasing superintendent while the vessel is still at sea, before the electrician is booked. Shore power turns a berth into a purchasing decision, and the buyers sit in different places. Technical superintendents at the ship manager judge whether a high-voltage shore connection fits the vessel, purchasing superintendents at the DOC holder release the budget, and port engineers or terminal operators buy the quay-side cable management. Bulk carriers are moving toward standardisation, so the busiest dry bulk terminals are where adaptors, converters and commissioning support will be ordered first.
