MaStR Scraper: German Solar, Battery & Wind Register

Scrape the Marktstammdatenregister (MaStR) — the official federal register of every energy installation in Germany, run by the Bundesnetzagentur — and get a lead list of the companies operating them, in the same run.

• ~9.7 million installations: solar parks, rooftop PV, battery storage, wind turbines, biomass, hydro and more — the single most complete dataset of the German energy transition
• Operator lead list included: the register publishes every operating company's address, email, phone, website, legal form and commercial register number
• Fast: official public data endpoint — no browser, no CAPTCHAs, hundreds of installations per minute
• Cheap: $1 per 1,000 installations, $8 per 1,000 operator profiles

Two datasets per run

Installations — one item per unit: capacity (kW), commissioning & shutdown dates, address with coordinates, voltage level, technology details (module count & orientation for solar, manufacturer/model/hub height for wind, storage capacity for batteries), operator name + MaStR ID.

Operators — one row per company:

{
    "name": "Photovoltaikkraftwerk Tramm GmbH & Co. KG",
    "street": "Poststraße 15",
    "postalCode": "20354",
    "city": "Hamburg",
    "email": "info@example.de",
    "phone": "040...",
    "website": "www.example.de",
    "registerCourt": "Amtsgericht Hamburg",
    "registerNumber": "HRA126655",
    "vatId": "DE267151615",
    "isSme": true,
    "totalCapacityKwInRun": 171604.68,
    "installationsInRun": 2
}

Use cases

• Solar installers & O&M: installations above X kW in your region, with the operating company behind each one
• Battery retrofit & repowering sales: plants commissioned before 2010 or 2015 — aging systems ready for upgrades
• Energy market research: new capacity by state/district/month, technology mix, operator consolidation
• B2B lead-gen: every company owning grid-scale assets, with direct contact details
• Grid / network analysts: capacity, voltage level and grid operator per location

Input

Field	Description
energyType	Solar/PV, battery storage, wind, biomass, hydro, natural gas — or all
minCapacityKw / maxCapacityKw	Capacity range (100+ kW skips home rooftops → commercial/utility scale)
state	Any Bundesland or all of Germany
postalCodePrefix, city	Location filters
commissionedAfter / commissionedBefore	Commissioning date range — new systems or old plants
status	In operation / planned / any
onlyOrganizations	Skip private rooftops, keep company-owned only (default on — private owners are anonymised anyway)
operatorNameContains	e.g. "Stadtwerke" or "Solarpark"
sortBy	Largest first / newest first
maxItems	How many installations
includeOperatorContacts	Emit the operator lead list

Examples

Solar parks > 1 MW in Bavaria:

{ "energyType": "2495", "minCapacityKw": 1000, "state": "1403" }

All battery storage commissioned in the last 90 days:

{ "energyType": "2496", "commissionedAfter": "2026-08-10", "sortBy": "InbetriebnahmeDatum-desc" }

Old PV plants (>100 kW) due for repowering in NRW:

{ "energyType": "2495", "minCapacityKw": 100, "state": "1409", "commissionedBefore": "2011-01-01" }
