meldra checks smart meter telemetry the moment it arrives and keeps the proof attached. And it turns everyday spreadsheets into charts, P&Ls and slides in plain English. Two products, one standard: answers people can trust.

Built on open technology
Different jobs, different people. The Smart Meter Platform is for teams who have to prove a figure. Insight is for teams who have to present one.
Verifies telemetry at the ingestion boundary and writes the proof into your lakehouse, so a settlement figure arrives with its evidence attached.
CHAIN_GAPUpload Excel or CSV, ask a question in your own words, and get answers, charts, P&Ls and slides you can hand straight to leadership.
When a counterparty or regulator challenges a figure, substantiating it today means days of pulling readings and writing a narrative. Hand back the figure, the snapshot it came from and the checks behind it instead.
The question you get asked
“Your August settlement for feeder F‑4471 looks high. Prove it.”
Readings for each meter-day are chained in sequence. A broken link is flagged where it occurs, instead of quietly disappearing into an average.
CHAIN_GAP is a column you can query, not a log line.mpan, settlement_period, feeder_id, gsp_group.The question you get asked
“Why does meter …0577 only have 47 readings for the 14th?”
Data lands as Apache Iceberg on your own object storage. Masking is applied to the Arrow data before the query engine ever sees it, so aliases, CTEs and SELECT * can't recover a masked value.
The question you get asked
“What happens to our data if we stop using you?”
Upload the spreadsheet, say what you need, and get the chart, the P&L and the deck. No VLOOKUPs, no pivot tables, no IT ticket.
The question you get asked
“Can I have Q3 by region on a slide before the board meeting?”
Encryption and authentication at the meter are solved problems. What isn't solved is integrity that survives into the data lake. That's where meldra sits.
Each block carries a monotonic nonce and an ECDSA P‑256 signature.
Ingress routes rotate every 60 seconds. Stale routes go to a decoy.
Nonce compare-and-swap, hash recompute, signature verify.
Verification state lands in Iceberg next to the reading.
Results return with the snapshot ID and per-row status.
Re-measured on 6 October 2026: single thread, 1,000 signed blocks from a meter simulator, on a standard laptop, median of five runs. Not yet run on real meters.
Most energy businesses need both: engineers who can defend a figure, and leaders who need it on a slide by Friday.
The Smart Meter Platform checks every reading on arrival and keeps the proof with the data.
Query the figure you need. It comes back with its snapshot and verification status, ready to export.
Upload the result to Insight and ask for the chart, the report or the board slide in plain English.
Energy data ends up in front of regulators, auditors and counterparties. Our own claims meet the same standard.
Every published figure comes with the conditions it was measured under.
What isn't finished is listed publicly, before you have to find it.
Meter data on storage you control. Spreadsheets not retained by default.
Least-privilege access, and secrets kept out of code and logs.
