  Southwest Power Pool publishes no client library in any registry. npm, PyPI and
  GitHub were searched for SPP-authored packages and none exist; SPP has no
  GitHub organization (github.com/SouthwestPowerPool returns 404). The community
  has filled the gap: SPP's public market data is one of the ISO/RTO feeds
  supported by the third-party gridstatus Python library, and an older Java
  client for SPP's CSV reports exists on GitHub. Both are recorded with
  official:false — they are not SPP software and carry no SPP support.

registries_searched:
- {registry: npm, query: 'southwest power pool / trolie', result: no first-party or SPP-specific package}
- {registry: pypi, queries: [spp-api, sppdata, trolie, trolie-client], result: all 404}
- {registry: github, query: southwest power pool, result: community repositories only; no SPP organization}
- {registry: maven-central, result: not searched — no evidence of any JVM client published by SPP}
gaps:
- SPP ships no SDK, no client library and no code samples for any interface
- the member-facing SOAP services are consumed from WSDL/XSD distributed inside the Change User Forum,
  with no generated-client distribution
