Raphson is AI-native grid software that runs the DSO's planning, operation and settlement on one physics-validated digital twin: observe, plan, connect, operate, maintain and settle.
One Platform
The whole grid lifecycle.
One canonical, physics-validated digital twin sits under every function, so the platform is a true source of truth rather than a set of synchronized silos.
A single physics-validated digital twin gets fully integrated with all different data sources and silos.
Model
The data backbone every other pillar runs on: one physics-validated, executable digital twin of the distribution grid, built from the DSO's own GIS, asset and metering data and versioned like code.

Reconcile LV phasing & connectivity, Floridsdorf
Agents write to planning branches only. Baseline changes are governed and re-validated.
Built & quality-scored
Assembled from GIS, asset registers and schematics, then auto-cleaned, reconciled and scored record by record.
Validated & inferred
Physics-and-topology checks catch bad data; gaps in LV connectivity and phasing are inferred and confidence-scored.
Versioned like code
Named versions, scheduled snapshots, diff, branch, rollback and full change lineage across the whole grid.
One integration hub
Connectors to GIS, ERP, AMI and SCADA (read-only); OT data arrives one-way through the DSO-side edge connector.
What the grid is doing now
Observe turns the telemetry and smart-meter data a DSO already has into a current, analytical picture of the as-operated grid: read-only, on the same physics-verified model.

- 12mSuspected switching, F12 tietopology drift
- 1hLoss signature, MV-08−6% delivered
Distribution state estimation
The full network state from sparse measurements plus pseudo-measurements, unbalanced at LV and confidence-scored where coverage is thin.
Read-only ingestion
SCADA telemetry and AMI interval values flow in (IEC 60870-5-104, DLMS/COSEM); no command or set-point ever flows out.
Drift & anomaly detection
Flags divergence between the as-operated state and the model: bad data, suspected switching, possible non-technical-loss signatures.
Power quality & congestion
Tracks loading and voltage against limits and EN 50160, surfacing the binding constraint and its headroom as congestion emerges.
Plan and justify investment on evidence
Plan reinforces the grid against scenarios and the regulatory network development plan, co-optimizing wires and non-wires on a TOTEX basis and calibrated against the grid's measured behaviour rather than static worst-case assumptions.
Scenario-driven planning
Generates EV, heat-pump, PV and electrification scenarios, then plans least-cost against each.
Wires vs non-wires
Co-optimizes reinforcement, storage (BESS) siting and flexibility on a TOTEX basis against the regulatory revenue cap.
Automated NDPs
Compiles the statutory distribution Network Development Plan under EU Directive 2019/944 Art. 32, consultation-ready and versioned.
Calibrated to measured state
Uses Observe's measured loading history and estimated headroom in place of static assumptions where data supports it.
Connect faster, on a defensible basis
Connect is the system of record for every connection request, from intake to offer, screening each against the live model and the planned grid, with hosting capacity surfaced and every determination engineer-signed.
| Ref | Request | Feeder | Hosting | Status |
|---|---|---|---|---|
| C-2291 | PV· 250 kW | F12 | headroom | Offer ready |
| C-2288 | EV hub· 1.2 MW | F07 | limited | Flexible offer |
| C-2284 | Load· 1 MW | F07 | full | Reinforce |
| C-2280 | PV· 90 kW | F03 | headroom | Eng. review |
| C-2277 | Storage· 800 kW | F12 | limited | Offer ready |
Single system of record
Intake to offer on one auditable record: assessment, capacity allocation, queue management, agreements and status.
Hosting-capacity screening
Load-flow, short-circuit and hosting-capacity checks across HV, MV and LV against measured loading, not static assumptions.
Flexible connections
Static or time-varying connection limits tied to the reinforcement timeline, where the grid is not yet reinforced.
Customer & community portals
Prosumer, PV and EV registration, metering-data access, GDPR requests and energy-community workflows.
Decisions up to, never including, control
Operate converts Observe's picture of the as-operated network into decisions: contingencies, congestion actions, switching drafts, flexibility and restoration support, executed by the operator in the certified control system and never by Raphson.

Contingency & congestion
N-1 and N-k screening on the operational network identifies the binding constraint; congestion is managed against it.
Operating envelopes
Computes time-varying connection limits and Volt/VAR set-point recommendations; the certified system enforces them.
Flexibility & curtailment
Drafts flexibility instructions and computes peak-shaving within statutory caps; the DSO applies them through its OT path.
Outage & restoration
Advisory restoration support and SAIDI/SAIFI reliability on versioned definitions, plus emergency coordination and reporting.
Keep the grid healthy and the crews working
Maintain manages the physical grid over its lifecycle: asset health and risk, predictive maintenance, protection coordination, and the field and construction work that keeps the model and the network in sync.

|---|---|---|
| T-12Transformer | 41 | High |

| T-08Transformer | 88 | Low |
| T-19Transformer | 92 | Low |
Transformer · thermal age + loading
Asset health & risk
Register, condition, criticality and aging models, fed by the loading and thermal history Observe accumulates.
Predictive maintenance
Condition- and risk-based scheduling drafts prioritized work orders into the CMMS/ERP, for approval and never auto-dispatch.
Protection coordination
Relay, recloser and fuse settings with short-circuit and arc-flash analysis; a protection engineer reviews and applies, never pushed to relays.
Field & construction
Work orders, inspections, as-built capture and capital-project management, with offline field apps feeding as-builts back to the model.
Meter to cash, on the network side
Settle is the DSO's regulated commercial backbone: the software layer between the AMI head-ends and the DSO's finance systems, covering validated metering, network-charge settlement, market communication and regulatory reporting. Never retail.

MDM / VEE at scale
Validation, estimation and editing of metering data, head-end-agnostic, so one validated source feeds settlement and Observe's state estimation.
Market communication
Jurisdiction-templated message sets (EDIFACT/AS4, IEC 62325/ebIX) and central data-hub exchange where a member state operates one.
Network tariffs & settlement
Netzentgelte design, dynamic and time-of-use tariffs, tariff-impact simulation, and energy-community allocation and settlement.
Regulatory reporting
Evidence packs, rate cases and incentive-regulation reporting; fraud and non-technical-loss cases originate as Observe's anomaly signals.
Why Raphson

Origin
Emerging from award-winning grid research at AIT
Raphson is emerging from a decade of distribution-grid research at AIT Austrian Institute of Technology in Vienna, work recognised with Austria's Houska Prize 2026. It is built and led by people who have both run real grids and scaled real software companies.
