Replacing diesel-generated power with simple and affordable wave energy

ResenWaves provides solutions for replacing diesel generation with wave energy buoys in coastal areas or on islands. The return on investment is typically 2 to 4 years, depending on the average wave height and the diesel price. If you want to learn more about possible savings, please fill in the Questionnaire, and we will provide you with a business case which will prove it to be good business for you and environmentally sustainable.

Simple installation

A group of small 2 or 5 kW wave energy buoys are placed close to the shore in a minimum water depth of 10 meters.

From the group of buoys a cable is laid to the shore, where it is connected to a diesel generator grid with an inverter. This can be supplied as a package with local training in installation and service.

As soon as the wave electricity is fed into the grid, the diesel generator will throttle back and save fuel.

Return of Investment of 2-4 years

In order to produce 1 kWh, a small diesel generator will use ½ liter of diesel oil. Even though the price for diesel varies, the price for electricity will always be very costly. It can be as high as 1 - 1½ USD per kWh. The diesel savings alone will allow the buoys to be paid for in 2-4 years. Low electricity costs will thus be a reality in the 15 to 20-year life span of the buoys.

Highly scalable

Wave energy can advantageously replace diesel power generation starting from 2 kW to 200 kW or more. New customers can start with a few wave energy buoys and gradually increase the number. For each buoy added, the diesel generator will throttle back, until it idles and can be put on standby.


The wave energy buoys are available as standard products ready to be shipped all over the world. 9 x 2 kW buoys or 6 x 5 kW buoys can be shipped in one 40’ container.

Resen Energy has been selected by the Danish Export Council to participate in the Green Vitus program. The program is only offered to 12 Danish SME´s (small and medium enterprises) with a big international growth potential. The program starts in August 2013 and will run for 18 months. We are very proud to be part of this focused export program.
