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.
We offer services for
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?
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 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.
We are "elena international GmbH", an interdisciplinary team of young visionaries and practitioners working towards the energy transition. We are scholars of the EXIST entrepreneurial scholarship from Humboldt-University and winners of the Leibniz transfer competition 2019 as well as the Leibniz Gründerpreis 2019. We are former project leaders in a Climate-KIC program, the EU's main climate innovation initiative.

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.

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!
