Design hybrid generation plants.
Model the network that connects them.
Build a demand profile, select generation and storage, and compare a full year of operation. Study plant size, reliability and cost. Then design the LV/MV network and check its electrical performance, all in one desktop application that solves on your computer.

A real project in the plant workspace: site, demand, weather and design in one place, with the latest run’s cost of energy, renewable share and unserved energy read straight from the saved result. Example values describe the interface, not a verified plant.

01The design process
One project. A sequence of engineering decisions.
Each stage hands the next its inputs. The demand, the resource data and every assumption stay attached to the project as the design develops.
- 01
Understand demand
Start with a site, a consumer mix or measured demand. Keep the daily shape and the source of each assumption.
Site & load - 02
Build the plant
Combine solar PV, storage and diesel. Add resource data, equipment ratings and the operating rules.
Weather & design - 03
Simulate a year
Follow generation, storage and demand through the modeled year. Find fuel use, surplus energy and unmet demand.
Annual operation - 04
Compare the choices
Search sizes, test uncertain assumptions and examine project finance before selecting a design.
Sizing & finance - 05
Connect the customers
Design LV/MV routes and equipment. Then check the network with separate electrical studies.
Network checks
02 / Generation & storage
Give every component a job.
Solar supplies energy when the resource is available. Storage moves it through time. Diesel or a grid connection carries the load when renewable output is low. The design canvas puts each component's rating beside its unit, so a kilowatt of converter is never confused with a kilowatt-hour of battery.
- PV, battery, converter, diesel, micro-hydro and grid connection, each with declared ratings
- Fixed sizes or search ranges for the equipment you want to compare
- An hourly, single-bus energy balance over the whole modeled year
- Unmet demand and curtailed energy stay visible beside the generation totals
An example design canvas with generation, storage, conversion and demand. Equipment settings and operating assumptions determine each simulation.
03Design decisions
Choose a feasible design. Test what could change it.
Equipment size is one part of the decision. Demand, weather, fuel prices and financial assumptions can change which option makes sense.
Sizing & trade-offs
Compare component sizes against stated cost and reliability objectives. Keep the constraints visible when reviewing a Pareto front.
Sensitivity & weather
Vary a declared assumption or weather case. Find which inputs change the answer before treating one result as a design basis.
Project finance
Bring capital cost, replacements, operating cost and revenue into a cash-flow model. Treat cost of energy and customer tariff as separate quantities.
04 / Powerline modeling
The plant is the beginning of the network.
Plan LV/MV routes, poles, conductors, transformer zones and service connections on the same demand basis as the plant. Compare network options and cost, then verify voltage and loading with the electrical studies.
- Routes, poles, conductors and service drops drawn over the site
- Conductor alternatives with cost, voltage and thermal findings side by side
- Commit the design to the electrical model and run power flow, short circuit and protection
- Styled GIS export: QGIS bundle, GeoPackage, GeoJSON or KML
A saved distribution example with vector geometry, equipment, costing and design findings. A separate example from the plant screens, and not an approved construction design.

Design a generation plant
Explain what serves the load, what limits the design, and what each delivered kilowatt-hour costs.
Generation plant design
8 pagesDemand, solar, storage, dispatch and cost: the decisions that size a hybrid plant.
Compare plant designs
6 pagesReliability, Pareto fronts, renewable share, weather risk and the finance behind a tariff.
Plant and network
6 pagesWhere the energy model stops and the feeder, conductor and grid questions begin.
Fundamentals
8 pagesThe quantities that every study uses: phasors, three-phase power, impedance and per-unit values.
Power flow
8 pagesHow a solver finds the voltage at each bus, and how to read the result.
Faults & protection
13 pagesShort-circuit currents, symmetrical components, and the relay settings that clear a fault.
Power quality
8 pagesHarmonics, unbalance, resonance, and the voltage sag that a large motor causes.
Network topology
2 pagesIslands, radial feeders, rings and meshes — the shape of the network.
AI inside the workflow
An assistant with access to the engineering tools.
Ask the agent to inspect inputs, run a study or explain a result. Model changes go through the application’s command gate, so you can review and undo each one. Calculations run locally; AI requests send relevant context to your configured provider, and weather retrieval uses external services.
How the assistant worksElectrical analysis
The studies stay part of the work.
Power flow, IEC 60909 short circuit, protection coordination and harmonic studies read the same model. Each study has its own required inputs, method and limits, and each result is traceable to the elements that produced it.
Explore the electrical studiesStart with the demand. Build from there.
Follow the plant-design guide from inputs to simulation, then connect the design to the network checks it needs. One application, no server to set up.
