Bring sizing, block diagrams, site planning, cable schedules and engineering deliverables together in one connected project workspace.
Changes in sizing feed the downstream views, so you spend less time moving numbers between disconnected spreadsheets and documents.
Enter energy, power, duration and block-level design choices.
Inspect sizing results and the electrical topology.
Explore layouts, feeder numbering and cable routes.
Check schedules, refine assumptions, prepare datasheets and procurement outputs.
Capture lessons with their source project for the next job.
Illustrative layout. Planners are engineering heuristics, not a global optimum.
Place equipment with several planners, edit the physical layout, add roads, and route cables. Compare cable lengths between feeder-numbering modes once you have run both.
Calculated from the design basis. An editable starting point, not a certified final design.
Topology follows the sizing inputs. Supports different tagging conventions.
| Cable | From → To | Length | Conductor | Check |
|---|---|---|---|---|
| F-01 | Block 01–08 → PEC 1 | 312 m | 3×1C 240 mm² Al | Pass |
| F-02 | Block 09–16 → PEC 1 | 388 m | 3×1C 300 mm² Al | Pass |
| F-03 | Block 17–24 → PEC 2 | 451 m | 3×1C 300 mm² Al | Review |
| AUX-1 | Aux. TR → LV panel | 96 m | 4C 95 mm² Cu | Pass |
Illustrative values. Per-row overrides stay editable; export to PDF or Excel.
| Characteristic | Example A | Example B | Example C |
|---|---|---|---|
| Energy per block (DC) | 3.72 MWh | 5.01 MWh | 6.14 MWh |
| Dimensions (L × W × H) | 6.06 × 2.44 × 2.90 m | 6.10 × 2.50 × 3.00 m | 6.10 × 2.44 × 2.90 m |
| Weight | 36 t | 40 t | 44 t |
| Clearances (front / sides) | 1.5 / 1.0 m | 1.2 / 0.8 m | 1.5 / 1.2 m |
| Auxiliary power (peak) | 18 kW | 24 kW | 27 kW |
| Energy per footprint | 0.25 MWh/m² | 0.33 MWh/m² | 0.41 MWh/m² |
| Blocks for 100 MWh | 27 | 20 | 17 |
| Site fit (2.0 ha) | Fits | Fits | Tight |
Example values for illustration only. In the application, the comparison is drawn from your shared product catalogue and its datasheets, so values are only as current as those entries.
Every output stays editable and exportable. These are working documents for engineering review, not a substitute for project approval or supplier verification.
Component documents you can review, edit and export.
Equipment list, RFQ packages, technical bid evaluation and a supplier database.
Compare two to five catalogue products with a simplified site-fit view.
Log the issue, root cause and mitigation, with area, severity, status and tags. Each lesson records its source project and stays searchable when another project is open.
A fast route from MW and MWh requirements to a coherent one-line concept and cable design basis.
Site and electrical information to build a scope of work and equipment list.
Design-linked equipment lists, RFQ packages and supplier offer review.
Visibility into assumptions, comparisons, checks and captured lessons.
Calculations depend on the project design basis and need qualified review plus vendor or study data.
AI-assisted design review, automated lesson matching, and company-level roles and approvals are planned directions, not current features.
Otoplan gives you an editable starting point for engineering review. The results follow from the design basis you enter, so sizing, cable ratings and layouts should be confirmed by a qualified engineer against project, vendor and study data before they are relied on.
The layout planners and cable routing apply engineering heuristics to give you a practical, reviewable proposal. They do not claim a mathematically optimal solution, and you can reposition equipment and re-run the routing as the design develops.
The comparator draws on the entries in your shared product catalogue and the datasheets behind them. We recommend confirming key values with the manufacturer before using them in a bid or a design decision.
Yes. The cable schedule exports to PDF or Excel, and datasheets and the EPC scope of work can be exported as editable documents for review and circulation.
Otoplan is currently shared within a single installation. Company-level accounts, roles and approval workflows are not yet available. If they matter for your team, please get in touch so we can understand your requirements.
Request a walkthrough and we will show how inputs become a reviewable electrical design.
