We enable our clients to build renewable power grids.

We develop customized solutions for various stages of power system planning: From investment planning to operational strategies and grid stability improvement. We offer our modeling expertise to microgrid developers, operators of islanded power systems and distribution grid operators. In all phases we ensure power systems which are reliable as well as economical providing high shares of renewable power.


Our Services

We offer services for

Microgrid Developers

Especially in small grids, grid stability is a concern leading to the limitation of renewables. At the same time renewable power can be cheaper and more resilient, especially in remote areas. What if all goals could be met: a high share of renewables, cost efficiency and a reliable grid operation?


Microgrid Operators

Blackouts and poor power quality harm or decrease the lifetime of infrastructure and appliances. What if you could plan your grid for different scenarios of load development and renewable energy expansion in advance so that your grid stays stable and operation is made easy?

Distribution Grid Operators

The requirements and regulations for distribution grid operators are changing. Distributed energy resources and electric mobility are making it difficult to operate the grid. Further challenges are  to handle big data and forecast the development of loads and generation. What if an analysis could give you a stable basis to build your decisions on?

Our Innovation

Our solutions for you:

Our novel modeling techniques can represent all frequency and voltage dynamics of a renewable power grid from subseconds to hours. So you can be sure your grid stays secure while increasing your share of renewables up to 100%.

Our analysis will show you the most cost-efficient and grid-secure way to transition to 100%. By suggesting optimal placement and usage of grid-stabilizing infrastructure such as flywheels or batteries, we reduce the cost of your energy transition drastically.

With our analysis tools you can increase the power quality in your grid and avoid blackouts. Hence, you can feel at ease when inviting more customers with high power and power quality demands to your location.

The computation will be done on our servers, so there is no need for any computational hardware while guaranteeing maximum data security.

Top 50 Start-ups 2019 Siegel.png

elena international belongs to Germany's top 50 startups

We are proud to announce that we have officially been selected as one of Germany's Top 50 Startups. Out of 741 startups we made it on place 22. For more information please visit the website of "Für Gründer"

Erigrid visit for software development

We spent two weeks at the smart grid laboratory at Tecnalia Research and Innovation in Bilbao. With scientists from Tecnalia and the Potsdam-Institute for Climate Impact Research, we pushed the development of our open-source library „PowerDynamics.jl“ for power system modeling.


elena international wins Leibniz Gründerpreis

More than 50 startup projects from the Leibniz Society competed at the Leibniz Gründerpreis which is endowed with 50,000 €. The winners were selected by a top-level jury and their choice was based on a submitted business plan. We feel very honored to be winners of this prize which we received at  the Leibniz spring reception in Berlin on March 22. The minister of science Dr. Martina Münch of Brandenburg congratulated us.

Windkraftanlagen in den Bergen

elena international at the Hybrid Power Systems Workshop

Elena international will take part in the Hybrid Power Systems Workshop from May 2019 in Crete. Sabine Auer will give a talk on off-grid power system planning and which Open-Source frameworks are suitable for such purposes. More than 80 international experts will present their projects and lessons learnt. Hence, the workshop is a great opportunity to exchange experience and meet stakeholders. For more information please visit http://hybridpowersystems.org/. We are looking forward to meet you there!
