EWK Monitoring (BNetzA)

Connection waiting times (Anschlussdauer) per VNB – median weeks per voltage level and installation type

Query BNetzA EWK connection-duration data for German distribution grid operators (VNBs).

Data source: vnb-transparenz.de/EWK-Monitoring-BNetzA — self-reported annual data from ~820 VNBs.

BNetzA indicators covered:

IndicatorDescription
4.3.1 / 4.3.2EE-Anlagen NS – Phase 1 (offer) / Phase 2 (commissioning)
4.3.3 / 4.3.4EE-Anlagen MS
4.3.5 / 4.3.6EE-Anlagen HS
5.3.1 / 5.3.2Verbrauchsanlagen NS (wallboxes, heat pumps, storage)
5.3.3 / 5.3.4Verbrauchsanlagen MS
5.3.5 / 5.3.6Verbrauchsanlagen HS

Use cases:

  • Identify slow-connecting VNBs as consulting/software-sales targets
  • §14a EnWG analysis: how quickly does a VNB connect controllable loads?
  • §11 EnWG NEST compliance: benchmark a VNB against the national median
  • Regulatory reporting: connection-time comparison for BNetzA submissions

Query parameters

tokenstring

Optional Cernion MCP token as URL query parameter. If provided, it overrides CERNION_TOKEN for this request. Prefer Authorization Bearer header in production to reduce token exposure in URLs/logs.

Request body

vnbNamestring

Partial VNB name search (case-insensitive, e.g. "Netze BW", "STROMDAO Netze")

bnrstring

BNetzA operator number for exact lookup

voltageLevel'NS' | 'MS' | 'HS' | 'all'

Voltage level filter: NS = low voltage, MS = medium voltage, HS = high voltage, all = no filter

installationType'EE' | 'Verbrauch' | 'all'

Installation type: EE = renewable generation, Verbrauch = consumption (wallboxes, heat pumps, storage), all = no filter

sortBy'name' | 'anschlussdauer_asc' | 'anschlussdauer_desc'

Sort order: anschlussdauer_asc = fastest first, anschlussdauer_desc = slowest first

limitinteger

Maximum number of VNBs to return

offsetinteger

Pagination offset

includeRankingboolean

Include national ranking (e.g. "42 / 739")

format'json' | 'csv' | 'xlsx' | 'xls'

Output format. "csv" and "xls"/"xlsx" trigger a file download.

tokenstring

Optional Cernion MCP token for this request. Overrides CERNION_TOKEN when provided.
