The question your lender, your auditor, and your plant head all ask the same way: "of the electrons the incomer brought in, where did they go — and does it add up?" Your SCADA tag list does not know what an incomer is. It knows a tag called RMU_01_P. Excel can't fix that.
The competition isn't another EMS vendor — it's the quiet cost of stitching five tools and one engineer together every month. And even the vendors who do sell you an EMS don't put all five capabilities in one layer.
| Capability | SCADA + Glue Code (what you have) | Other EMS Vendors (what the market sells) | twinos |
|---|---|---|---|
| Dual-protocol native (Modbus + IEC 61850) | Custom tag-mapping glue | Usually pick one | ✔ Native · one service |
| Topology-aware rollups (bus balance) | Excel approximation · brittle | Flat meter list | ✔ First-class data model |
| Shift as a dimension | CASE WHEN · breaks on DST | Calendar-only reports | ✔ Timezone-aware · overnight-safe |
| Power quality + cost in one record | Two pipelines · never in sync | PQ sold as separate module | ✔ Unified sample stream |
| Reports as versioned JSON templates | Bespoke Excel every month | Closed report-builder or HMI | ✔ Diff-able · reproducible |
| Auditor · lender · BRSR-grade evidence | Unreproducible | Disclosure-grade at best | ✔ Covenant-grade |
