Glossary
MaStR domain terms, as the CLI surfaces them. Field labels in the data are German; keep them verbatim.
| Term | In the CLI | What it is |
|---|---|---|
| MaStR | — | Marktstammdatenregister, the Bundesnetzagentur’s register of the German electricity & gas market: master data on ~9M generation/consumption units and market actors. |
| Einheit (unit) | a row | A single registered unit — a PV system, wind turbine, storage, CHP block, consumer, etc. Keyed by its MaStRNummer (e.g. SEE984033548619). |
| Stromerzeugung / Stromverbrauch | stromerzeugung / stromverbrauch |
Electricity generation / consumption units. |
| Gaserzeugung / Gasverbrauch | gaserzeugung / gasverbrauch |
Gas generation / consumption units. |
| Energieträger | EnergietraegerName / filter |
Energy carrier — Solare Strahlungsenergie (solar), Wind, Biomasse, … Filtered by a numeric code (e.g. 2495 = solar). |
| Bruttoleistung / Nettonennleistung | fields | Gross / net rated capacity, in kW. |
| Betriebs-Status | BetriebsStatusName / filter |
Operating status — In Betrieb (in operation), In Planung, Endgültig stillgelegt, … (filtered by code, e.g. 35 = In Betrieb). |
| Anlagenbetreiber / Netzbetreiber | AnlagenbetreiberName / NetzbetreiberNamen |
Plant operator / grid operator. Operator names are often anonymised (natürliche Person (ABR…)). |
| Total | total |
The full number of units matching the query, across all pages (respects the filter). Returned for free — use --total. |
| Filter / Sort | --filter / --sort |
Kendo-grid selection. Filter: FilterName~op~'value'~and~… (or ~or~), with the FilterNames from mastr filters and the operators eq, neq, sw, ct, nct, ew, null, nn, gt, lt (an unknown operator returns 0 rows). Sort: FieldKey-asc or FieldKey-desc, where FieldKey is a record field name such as Bruttoleistung, not a FilterName. |
/Date(ms)/ |
--iso-dates / parseMsDate |
A Microsoft-AJAX date (epoch-milliseconds, UTC). --iso-dates rewrites them to ISO-8601. |
Reading a record
- Capacities are in kW; divide by 1000 for MW. Gross (
Bruttoleistung) ≠ net (Nettonennleistung) — say which. - Dates are
/Date(ms)/— convert with--iso-datesbefore showing a human. - Coordinates (
Breitengrad/Laengengrad) may be null, and some location data is withheld for small (< 30 kW) units — by law, not a defect. - Rows are wide and vary by category — only read fields that are present.
