Tools & Instruments

Interactive diagnostics, data instruments, and design prototypes. These tools operationalise ACI analytical frameworks against live or reference data. They are not publications — they are instruments.

Note on tool status
Live data tools require a Fingrid Open Data API key, available free at data.fingrid.fi. Dataset IDs should be verified before deployment as Fingrid has changed identifiers historically. Design prototypes are not functional and are provided for reference only. Tools in this section are experimental and subject to change independently of the publication versioning cycle.
