Energynautics

What Energynautics does

Energynautics GmbH is a Darmstadt, Germany-based consultancy founded in 2000 that specializes in the grid integration of variable renewable energy, distributed energy resources, and electromobility. The firm serves transmission system operators, distribution system operators, municipal utilities, government ministries, and international development organizations across more than 60 countries, with 370+ completed projects spanning grid studies, distribution grid planning, smart grid consulting, power generating unit modelling, grid code development, power system optimization, measurement campaigns, electromobility advisory, and capacity building.

The company combines industry-standard simulation software (DIgSILENT PowerFactory, PSS®E, PLEXOS, HOMER) with two proprietary assets: ENAplan, an in-house grid optimization tool that co-optimizes generation dispatch, grid expansion, and storage using mixed-integer solvers, and the Prognos Tool, a web-based forecasting platform co-developed with enwarp gmbh and Thüga AG that delivers building-level load and generation projections for low-voltage grids. The firm is led by managing directors Dr. Thomas Ackermann and Dr. Eckehard Tröster and maintains around 35 employees.

Commercially, Energynautics operates a sales-led, project-based professional services model with custom-quoted engagements and recurring conference and conference-adjacent revenue streams. Its GTM motion relies on direct enterprise relationships with utilities and TSOs/DSOs, international tender wins channeled through development finance institutions such as GIZ, GET.transform, and IRENA, and an industry-defining portfolio of self-organized annual workshops (Wind & Solar Integration Workshop, E-Mobility Integration Symposium, Hybrid Power Plants & Systems Workshop) that function as both thought-leadership platforms and client acquisition channels. Pricing is not publicly disclosed and is determined per project by scope, duration, and complexity.
