Shore Power

Flexible, effecient, and cost-effective shore power that allows ships at berth to plug into the electrical grid and turn off their auxiliary diesel engines.

Shore Power Benefits

  • No emissions
  • No noise
  • No vibration
  • Lower fuel consumption
  • Lower wear and tear
  • Easier maintenance

Also known as Onshore Power Supply (OPS), cold ironing, shore-to-ship power and shore-side electricity to name a few terms, PowerCon pioneered the shore power industry with a more innovative, modular approach to the technology. We think of shore power more as a product rather than an engineered solution that has to be built from scratch every time. By integrating our main components into standard shipping containers, we pioneered the “building block” approach to shore power, which allows us to put together the most suitable solution for any port.

The benefits of containerized shore power are many. Most importantly, the containers allow us to pre-manufacture, pre-assemble, and pre-test our solutions in our factory before we ship them on-site, where the containers also ensure easy and fast installation.

PowerCon’s industry independence allows us to use the best and latest technologies and materials in putting together the best possible shore power solutions, whereby you also avoid a “closed box” solution or a proprietary technology that will limit your future adaptability and scalability.

We build our systems according to the international standard for shore power (IEC/IEEE/ISO 80005). PowerCon supplies both high and low voltage shore power solutions and covers all vessel types, from the largest cruise ships to container ships to smaller fishing vessels and ferries, which some of our main references below also show.

Underlining PowerCon’s experience and capabilities within shore power, we are often chosen as turn-key supplier or prime contractor, undertaking the complete scope of a shore power project and implementing an end-to-end solution. These additional tasks can include grid connection upgrades, civil works, cabling, switching stations, connection boxes, cable management systems (CMS) as well as all related services like maintenance, daily operations, etc. For some of those tasks, PowerCon works with a number of trusted sub-suppliers to make sure that all parts of the project scope get the needed attention and level of quality.

This is especially true for the cable management system (CMS) which is the solution at the berth that feeds the cables from the quay to the ship. Although PowerCon has its own designs, several other companies specialize in these CMS solutions, offering variable degrees of flexibility and price points. Some of them are listed below and PowerCon has worked with all of them.


Low-cost and flexible onshore power supply for containerships and onboard battery charging


Containerships rely on the highly pollutant marine fuel to operate, contributing to 50-60% of all ship emissions. Onshore power supply (OPS) is the delivery of shore side electrical power to a ship at berth so its main and auxiliary engines can be turned off. In the cases where the electricity comes from renewables, OPS is a local mitigation measure that eliminates all CO2, air pollutants, noise, and vibration at the port terminal. However, with the possibility to charge onboard batteries, OPS can also have a significant global CO2 mitigation potential.

PowerCon pushing the boundaries
PowerCon has in the recent years been a part of the success of OPS systems for the cruise ships segment by adding significant savings to cruise ports, making it obvious to offer the same savings to the containership segment and expand the system capabilities to charge onboard batteries. Therefore, the main objective of this project is to advance the technological and market readiness of a competitive OPS solution – named OPS-Charger – to provide electricity to containerships when at berth to supply their consumers and charge onboard batteries. For 36 months, we will mature, test, and demonstrate OPS-Charger in a real case scenario.

The main outcome of the project is a market ready solution to offer for the first time a cost-competitive and flexible OPS solution for containership ports around the world, ensuring a reasonable payback period. The market adoption of our solution is expected to contribute to:

1) reduce greenhouse gas emissions, pollution, noise, and vibration from containerships at the port berth and sea, thereby contributing to the UN Sustainable Development Goals 3, 7, 9, 11, 13, and 14.
2) the circular economy.
3) the creation of high-value blue economy jobs.

Overall, the ambition of this project is to significantly impact the blue economy areas of “New facilities that support the diversification or energy efficiency of ports” and “Cleaner shipping”.
