  https://drpep.sce.com/arcgis_server/rest/info?f=json + live probes of SCE status/deprecation surfaces
  (2026-07-27)
summary: >-
  SCE operates its API surfaces with no published lifecycle at all: no versioning policy, no deprecation
  policy, no Sunset/Deprecation header support, no API status page, no SLA and no changelog. What does exist
  is data-level vintage stamping inside the DRPEP layers themselves, plus the CPUC regulatory calendar that
  drives when the ICA/GNA/DDOR/LNBA datasets are refreshed.
versioning:
  scheme: server-product-version (exposed, not negotiable)
  current: '11.1'
  discovery: https://drpep.sce.com/arcgis_server/rest/info?f=json
  full_version: 11.1.0
  policy_url: null
  client_pinning: false
  note: >-
    There is no version segment in the path, no version header and no date pin. A consumer is always on
    whatever ArcGIS Enterprise version SCE last upgraded to, and an Esri major upgrade can change response
    details without notice.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  deprecated_operations: []
  note: >-
    No deprecation policy, no RFC 8594 Sunset support, no advance-notice commitment. Layer names carry their
    own dating instead - e.g. the service DRP_ScreenL_08202021 is stamped with a 2021 date in its own name,
    and superseded layers simply disappear from the Hosted catalog.
data_vintage:
  mechanism: in-band, per dataset
  sources:
  - table: ICA_Tables/0 (DRPEP_FGDB_DATE_TIME)
    meaning: Refresh timestamp of the ICA file geodatabase publication.
  - table: DDOR_Layer/3 (DDOR FGDB DATE TIME)
  - table: GNA_Layer/4 (GNA FGDB DATE TIME)
  - table: LNBA_Layer/4 (LNBA_FGDB_DATE_TIME)
  - field: ICA feature layers carry changed_date and changed_date_forecast per circuit segment.
  recommendation: >-
    Poll the FGDB DATE TIME tables to detect a data refresh; there is no webhook, feed or notification of any
    kind for these datasets.
release_cadence:
  driver: CPUC Distribution Resources Plan / Distribution Planning Advisory Group calendar
  note: >-
    ICA, GNA, DDOR and LNBA are regulatory deliverables under the CPUC DRP proceeding, so refresh cadence
    tracks the proceeding's filing calendar rather than any product release train. SCE publishes no
    machine-readable schedule.
status_page:
  url: null
  note: >-
    No API status page exists. status.sce.com does not resolve. https://www.sce.com/outage-center/check-outage-status
    and the SCE outage map are ELECTRICITY outage tools for customers - they report power outages, not API
    availability - so they are deliberately NOT recorded as a StatusPage pointer.
sla:
  url: null
  uptime_target: null
  note: >-
    No availability commitment is published for DRPEP or for Green Button Connect My Data. SCE's "service
    guarantee" pages concern electric service, not API uptime.
changelog:
  url: null
  note: >-
    No dated API changelog. Corporate news is published at https://newsroom.edison.com/ (Edison International)
    and is not an API changelog, so no ChangeLog pointer is emitted.
green_button:
  lifecycle_published: false
  regulatory_anchor:
    tariff: SCE Rule 26 - Release of Customer Data or Energy Usage Related Data to Third Parties
    advice_letter: 3087-E
    filed: '2014-07-30'
    effective: '2014-08-29'
    decision: CPUC D.14-05-016
    document: https://www.sce.com/sites/default/files/inline-files/Rule26.pdf
  note: >-
    The tariff is the only durable versioned artifact for the consumer-data interface. Rule 26 states that
    "technical eligibility criteria may change, from time to time, consistent with the NAESB ESPI Standard" -
    i.e. the interface can change with the standard, with no consumer-facing versioning contract.
