Search power generation units (Stromerzeugung) — no auth required.

The primary tool for finding wind turbines, solar panels, biomass plants, hydro, storage, gas turbines, nuclear plants, etc. in the MaStR register. Supports all 20 energy carriers with 27 filter keys and 10 operators.

Use this as the default search tool for power generation questions. For full unit details after finding a MaStR number, use get_unit (SOAP).

Search market actors (Marktakteure) — no auth required.

Find energy market participants: DSOs (Netzbetreiber), generators, suppliers, traders, and more. 23 filter keys for name, function, role, location, status, and DSO flags (large DSO, closed distribution network).

NOTE: MaStR stores '&' as fullwidth U+FF06 in company names. Use 'name%' with a substring without '&' for reliable company name searches.

Search power consumption units (Stromverbrauch) — no auth required.

Find large electricity consumers registered in MaStR. 29 filter keys covering identification, location, dates, voltage level, and DSO checks.

Use this when searching for electricity consumers (not generators).

Search gas production and storage units (Gaserzeugung) — no auth required.

Find biogas plants, Power-to-Gas (hydrogen/methane), LNG terminals, fossil gas producers, and gas storage units. 30 filter keys including gas technology and unit type (producer vs. storage).

Search gas consumption units (Gasverbrauch) — no auth required.

Find registered gas consumers. 30 filter keys covering identification, location, dates, gas quality (H-Gas/L-Gas), maximum capacity, and whether the gas is used for power generation (gas_for_power flag).

Search grid connection points and locations (Netzanschlusspunkte) — no auth required.

Find where units connect to the grid. Returns location data, grid connection points, linked units, DSO info, and network parameters. Supports 4 connection types: power generation/consumption and gas production/consumption. Power types include voltage level, control area, and balancing area. Gas types include gas quality and market area.

For grid connection details of a specific unit, use get_grid_connection (SOAP).

Connection test — returns current server time if MaStR SOAP service is reachable.

No authentication required. Use this to verify network connectivity.
