Who We Are


Energen is a Stockholm based company concentrating on intelligent solutions for the storage of high volumes of electricity as well as Virtual Power Plant systems. Its IntelliStore product line is geared towards TSO’s, alternative energy producers and other industrial clients. With its high capacity bi-directional inverters the products’ main focus is network and grid operations – but they are equally suitable for purposes of arbitrage, ramping, UPS or island operational mode.

How We Work



We know that electricity storage is more than just storing: it all comes down to security, phasing, ramping, quality and bridge times. Hence Energen is proud to provide individual service and support – and able to manufacture according to individual specifications of electricity generators, alternative producers, grid operators, industrial clients, utilities and many more.

Let us calculate and plan for you.


News & Publications


Energen's IntelliStore 1000 has been connected to a gas-fired electricity generator plant. With its 900 MW installed generator capacity the plant is an ideal site to use the storage device for ramping and phasing services. If idle, the plant's own electricity usage is optimized - no peak prices need to be paid.


Energen's IntelliStore 1000 solution - as connected to the gas-fired electricity generator plant - has been uploaded to the U.S. Department of Energy's DOE Global Eneregy Storage Database.


Energen's brand new 500 kW bi-directional inverter system is ready to use. The 2DI-500 will support larger storage projects.
