Minimise total cost
ENERsim finds the configuration and dispatch strategy that minimises capital and operating costs across the system's entire lifetime.
ENERsim models complex energy systems and optimizes them for cost, CO₂ and resilience — from early design to commercial operation.
About ENERsim
ENERsim is a simulation platform for modern energy systems. Integrate any mix of energy sources, converters, storage units and consumers — then analyse performance, evaluate efficiency, and assess economic viability and environmental impact across every scenario.
Why ENERsim
Cost, emissions and resilience are optimized simultaneously — not in isolation.
ENERsim finds the configuration and dispatch strategy that minimises capital and operating costs across the system's entire lifetime.
Quantify and cut emissions by optimally sizing renewables, storage and converters around your real load profiles.
Design systems that ride through outages and demand peaks, balancing reliability against cost and emissions.
Services
An intuitive interface to build, simulate and optimise energy systems right in your browser.
Tailored models and solutions for the components and constraints unique to your system.
Hand us your data — we deliver the optimised system design and a clear analysis.
A REST API with SDKs to embed ENERsim in your own tools and control loops.
The platform
ENERsim turns a system definition into actionable results — costs, efficiency, emissions and autarchy — with transparent energy-flow and optimization analysis.
| Parameter | Value | Unit |
|---|---|---|
| Net annual costs | 0.000 | EUR |
| System efficiency | 100.000 | % |
| Annual CO₂ emissions | 0.000 | kg CO₂equ |
| Autarchy (weighted) | 100.000 | % |
Use Cases

Design self-sufficient grids that balance solar, wind, storage and demand — islanded or grid-connected.

Combine renewables, storage and conventional generation into one optimally dispatched plant.

Optimise on-board and shore-side energy for vessels and ports, including alternative fuels.

Size and schedule electrolysers and e-fuel plants against renewable supply and demand.
Partners
Together with HDC Solutions and the THORIUM initiative, ENERsim helps design energy systems that keep critical operations running — whatever the conditions.
Trusted by engineers
"ENERsim let us compare dozens of system designs in days, not months."
"Finally a tool that weighs cost, emissions and resilience in the same model."
"The API made it trivial to fold optimisation into our own workflow."
