Dear ,


The development in hybrid powers systems is advancing rapidly, thus it is crucial for those involved in the subject to exchange experiences, discuss common problems as well as possible solutions.

Energynautics offers a platform for discussion and sharing ideas: the 4th International Hybrid Power Systems Workshop from 22-23 May 2019 in Crete, Greece.


As an expert in isolated power systems with a high share of renewable energies, Energynautics also offers consulting services for all projects concerning island power systems and micro-grids.

In this newsletter, we would like to showcase some of our most interesting ongoing and recently concluded projects with a focus on this area of expertise.

The Call for Papers for the 4th International Hybrid Power Systems Workshop has started.

Submit an abstract until 15 January and join us in Crete, Greece!



Best regards,

Renewable Energy Integration in Island Grids


Several thousand inhabited remote islands worldwide are supplied with electricity by small distribution grids, mainly powered by diesel generators of various types and sizes. Compared to larger power systems, generation cost in such systems is very high, as expensive diesel fuel has to be shipped in continuously. Hence, these islands can greatly profit from the falling costs of renewable energy, relieving local pollution issues at the same time.

From 2014 on, Energynautics has been active in island grid studies, starting out with a wind and PV impact study on the Seychelles and the development of grid code documents for the Seychelles and Barbados.

In November 2017, Energynautics signed a multi-year contract with Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ)/German Corporation for International Cooperation, for the Renewable Energy Electrification Program REEP 1000 Islands in Indonesia. This program intends to assist Indonesian utility PLN in integrating wind, PV and biogas resources in their more than 600 island grid systems, with the goal of driving down electricity cost and local emissions. Energynautics engineers already visited two remote islands and conducted pilot grid studies, and the project will continue with studies and actual project implementations until 2020.

Small diesel based systems present a set of unique challenges and opportunities for renewable energy integration, the in-depth study of which is currently a hot issue in the power systems community. This topic is discussed with international experts, stakeholders and manufacturers at Energynautics’ annual Hybrid Power Systems Workshop.

Selected Energynautics Island Grid Projects


[Clients: World Bank & Utility Seychelles]


Grid Absorption Study Seychelles: In 2014 Energynautics was commissioned by the World Bank and the Government of the Seychelles, along with our project partners Meister Consultants Group, to investigate the technical and economic barriers to reaching higher renewables penetration. More



[Client: Barbados Light & Power Company, Barbados]






Barbados Grid Code Review: The Barbados Light & Power Company (BLPC) has commissioned Energynautics to review and expand its grid code, which regulates the technical requirements for distributed generators to connect to the utility’s grid. More



[Client: Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), Germany]



REEP 1000 Islands: GIZ has commissioned Energynautics to conduct pilot studies for renewable integration on two Indonesian islands. The Indonesian government has set a national target of 23% electricity from renewable sources by 2025. Hybrid systems on the more than 17,000 small Indonesian islands can contribute significantly to reaching this goal. More

Selected Energynautics Projects 2018


[Clients: World Bank & NDC Mongolia]


Grid Code Revision for Mongolia: The World Bank has commissioned Energynautics to assist the National Dispatch Center (NDC) with a revision of the Mongolian grid code with special focus on renewable energy integration until the end of 2018. A training workshop in Ulaanbaatar has already been held by Energynautics CEO Dr. Thomas Ackermann. More



[Client: IFW Kiel Institute for World Economics, Germany]





Electricity Market Simulations for ETS Plus Emission Trading Project: Energynautics used a stripped down version of their dispatch simulation and grid optimization tool ENAplan to conduct simulations of the European wholesale electricity market in 2030 under various emission and fuel prices. More



[Client: Consortium of several NGOs, Czech Republic]



Transmission System Study Czech Republic published: Energynautics was commissioned by a consortium of NGOs to conduct a high level transmission system study to investigate the impact of a large scale coal exit in the Czech Republic by 2030. Study results were published on May 22nd and presented at a press conference and expert workshop in Prague. More



[Client: Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), Germany]



Successful Acceptance Test of in-house development PV Port: Energynautics and PA-ID successfully presented the PV Port prototype to the German development agency GIZ. The snoopiXcontroller, a control box developed by Energynautics, ensures that the PV-battery plug & play system increases the own-consumption and that no power is exported to the grid. More

Conferences organized by Energynautics

3rd International Hybrid Power Systems Workshop from 8 - 9 May 2018 in Tenerife, Spain


The third edition of the International Hybrid Power Systems Workshop that took place from 8-9 May 2018 exceeded all expectations with its 129 participants from 30 countries.


The workshop participants made good use of this unique opportunity to discuss the challenges that arise when high shares of renewables (wind, solar, hydro) are integrated into island power systems/micro-grids, in combination with conventional power generators and optionally batteries/flywheels.



With a total of 14 sessions and more than 50 presentations the spectrum of topics included in the Workshop ranged from hybrid system technologies and system modelling/simulation to intelligent control and grid stabilization as well as Mini-/Micro-Grid system design. Storage issues were covered as well as economic issues.
