Good Energy

Good Energy Customer Identity (OpenID Connect)

The OpenID Connect / OAuth 2.0 identity provider behind Good Energy's customer hub at account.goodenergy.co.uk. It is NOT a developer-facing API and Good Energy publishes no documentation for it — it is listed here only because its discovery metadata is served anonymously and machine-readably at https://login.goodenergy.co.uk/.well-known/openid-configuration (HTTP 200, application/json, fetched 2026-07-27), making it the only harvestable API contract the company exposes. The document advertises a Duende IdentityServer style surface with authorization, token, userinfo, introspection, revocation, device-authorization, CIBA and PAR endpoints, PKCE (S256), DPoP signing algorithms, and the scopes openid, profile, email, offline_access, customer_portal and customer_portal_tariff_switch. There is no registration_endpoint, so no third party can obtain a client; access is customer-account-required.
