Unit lists, operators and grid operators cover units over 100 kW gross capacity; units operated by private individuals are shown without name, operator or coordinates. Capacity is gross capacity (Bruttoleistung) as registered; planned units are those registered as 'In Planung'. District (Landkreis) is the register's own assignment. Source record.
Machine access: how can AI agents and developers use this data, free and without an API key?
Every figure shown here about How many storage units are registered in Westerwaldkreis (Rheinland-Pfalz), and how large can also be queried live: FACTANKER runs an MCP server at https://factanker.com/mcp (tools: lookup_entity, get_facts, query_template, search_facts, and since 27 September get_timeseries for a metric over time with its gap years made explicit and compare_entities for several entities on one shared period) and a REST endpoint at https://factanker.com/api/get_facts. Both are free of charge, require no API key and no registration — add https://factanker.com/mcp as a connector in Claude, ChatGPT or Copilot. Every answer carries its source document and a citation reference. Setup: /quickstart.
