Complete Electrical System Design

We understand designing a new vessel from start to finish, following an initial design brief to a fully detailed specification, takes time and attention to every detail. We have 20 years experience designing marine electrical systems, and the capability to provide high quality electrical design solutions to the latest standards.

Through our professionally qualified and experienced team, we offer design packages covering both the work and leisure sectors of the marine industry.  Operating the latest design software our in-house engineers can deliver systems tailored to meet the exact needs of your customers.

In addition we are able to manufacture panels and switchboards in our UK production facility and undertake programming and commissioning for clients.

Our design services include:

  • Single line schematics
  • Panel wiring diagrams
  • 2D and 3D layout diagrams of panels
  • Full boat interconnection wiring diagrams

Our engineering services include:

  • Panel & switchboard manufacture
  • Specification & supply of power units
  • PLC programming
  • Commissioning

Our engineers are used to working on international projects and are able to work to Lloyds, DNV and RINA standards as well as a full range of ISO standards.


We will carry out the entire electrical design including load analysis for your project. This will generate a detailed set of drawings, bills of materials, cable schedules and any custom system design that may be required.

We design and build AC and DC electrical panels. This can involve generator sets in parallel (isochronous or droop), load management and monitoring. If required we can build remote monitoring and control panels. 

We provide PLC Programming for alarms and other systems. Large systems have complex alarm, monitoring and control requirements, PLC control allows these needs to be met in a flexible and upgradable way.



Marine Helm Panels

We offer a range of electrical design and build services to the marine industry. Our bespoke panel building capabilities allow us to build to your exact requirements.




The integration of electrical & electronic systems into a common shell with the ability to distribute the information simultaneously to strategically located control / monitoring stations is becoming the standard rather than the exception.

E-Plex is the next-generation of multiplexing technology for boat builders.


ES LoadBank

Our ES LoadBanks combine a heater tank, switch gear and expansion tank all in the same enclosure, reducing the footprint required to install the LoadBank. The PLC allows direct interfacing with a ship's system for control and monitoring. There is also a remote touchscreen control and monitoring panel, both options give flexibility for new builds and retrofits.



Technicold - Custom Climate Solutions

Energy Solutions are the UK Distributor for Technicold - Northern Lights marine air conditioning and refrigeration division. The systems we are able to supply are specifically tailored to the larger yacht market, with outstanding performance for the mega yacht and superyacht markets.



Generators and Air Conditioning

Energy Solutions are the UK distributor for Northern Lights generators and Technicold air conditioning. The NL brand delivers an award winning level of reliability, durability and simplicity – which matches the demands of both leisure and commercial boat builders and owners.



Marine Isolation Tranformers

Our standard transformer range covers 10, 16, 32, 50, 63 & 100 amp single phase shore capacities at 230v. We offer custom units in single phase, three phase to three phase and three phase to single phase.

In addition to these fixed ratio transformers (normally 1:1) we supply voltage converting transformers. Smaller transformers are offered that will boost 115 volts to 230 volts or visa versa. These are available as manually configured or auto changing.


Iso-Boost transformers

For USA spec boats we offer a replacement for the Charles Industries Iso-Boost transformer. This has two input voltage ranges at 208 volt and 240 volt nominal to allow a boat to connect to 2 legs of a 208 volt three phase supply in the USA or to a 240 volt split phase supply. The transformer automatically selects the appropriate input. This can also be helpful if your 240 volt supply is weak (for instance if you are at the end of the dock).


ES DockPower - Dual shore cord isolation transformer

The demand for shore power means that larger motor yachts often have dual 32A or even dual 63A shore power sockets. This requires the boat’s internal AC circuitry to be split into two entirely separate groups - normally air conditioning and domestic. But if one circuit tries to pull more than the maximum rating there’s nothing to be done to stop the dockside load circuit breaker tripping, even if the other cord has plenty of capacity left.



ASEA Frequency Converter

Since 1999 we have been supplying ASEA frequency converters with a complete technical back up and commissioning service to UK customers. In 2019 that territory expanded to include Holland, Germany, Denmark, Finland, Norway and Sweden. Across all these countries we work with leading OEMS, ship yards, individual boat owners; providing them with a full service from initial enquiry to specification to supply and commissioning onboard.  

Over the years the ASEA range of products has grown to become one of the most comprehensive ranges of frequency converters in the world. Based in California, ASEA Power has a proud legacy of innovation and performance building their wide portfolio of products to exceed industry safety standards, making them a brand of choice for quality boat builders. The ASEA range brings the advantages of shore power conversion to vessels of all sizes. The ability to plug into any shore power supply across the globe whether they are a smaller yacht or a superyacht, has led to ASEA frequency converters being installed in superyachts and OEM ranges worldwide.



WaterWorld - the electric drive

Hybrid On-Board Power Systems

Powering on-board appliances, tools, media and amenities is a vital part of the design for boat builders whose customers are looking to run increasing technology, work equipment and mobile comfort even when their generators or engines are not running. Whether it is a recreational or commercial vessel, efficient and effective power solutions are a key element for owners looking to increase their available power with reduced generator runtime and lower emissions.


Why Lithium?

Lithium battery systems provide a significant improvement on existing power technologies in a number of ways.

  • The systems allow boat builders to provide more power from a smaller battery footprint meaning more space on-board  and longer periods of power use.
  • Lithium batteries offer much greater efficiency – the battery can be recharged to 90% in just one to three hours* so the system can be bought back to full power ready for work.
  • The batteries will last almost twice as long as a gel battery, so they will not need to be replaced as quickly, increasing the cost efficiency of the system.

We have developed a fully scalable lithium battery system for vessels – it delivers fast & efficient power whilst taking up the least amount of space and saving weight. The system offers truly independent power that can easily be recharged from the engine, generator or shore connection when needed.
