Simply Energy is the former brand of the Australian electricity and gas retailer that now trades as ENGIE, operated by IPower Pty Ltd (ACN 111 267 228) and IPower 2 Pty Ltd (ABN 24 070 374 293) trading as ENGIE (ABN 67 269 241 237), together with Simply Energy Solutions Pty Ltd. The business carried the Simply Energy name for seventeen years before rebranding to ENGIE in April 2024, and supplies more than 700,000 residential and business accounts across Victoria, South Australia, New South Wales, Queensland and Western Australia. It sits on the retail tier of the National Electricity Market value chain, buying wholesale energy and billing end customers, rather than in generation, transmission or distribution. Its API posture is entirely a product of statutory mandate, and in this case the mandate is genuinely implemented rather than merely claimed. The company is a designated Consumer Data Right energy data holder (data holder provider number DH002028) and is listed on the live CDR Register under the ENGIE brand. Its unauthenticated CDR Generic Plans endpoint, hosted for it by the Australian Energy Regulator's Energy Made Easy service, returns 2,452 real ENGIE tariff plans conforming to the Consumer Data Standards energy schemas, and its own registered public base URI serves the Consumer Data Standards discovery endpoints with correct x-v version negotiation. Everything else is closed. Customer usage, billing, service point and DER data are available only to ACCC accredited data recipients with explicit consumer consent, there is no developer portal, no self-serve API keys, no published OpenID Connect discovery document, and no open grid, market or system data of any kind.
Simply Energy publishes 3 APIs on the APIs.io network: (ENGIE) CDR Energy Generic Plans API, (ENGIE) CDR Discovery API, and (ENGIE) CDR Energy Consumer Data API. Tagged areas include Energy, Australia, Utilities, Electricity, and Gas.
Simply Energy’s developer surface includes documentation, API reference, engineering blog, authentication, changelog, and 26 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

description: The Consumer Data Standards Common Discovery API served from the brand's own registered CDR Public Base URI.
Confirmed live on 2026-07-27. GET /discovery/status returns HTTP 200 at x-v 1 with status OK, and GET /discovery/outages
returns HTTP 200 at x-v 1 with an empty outages array. Both correctly reject x-v 2 and above with urn:au-cds:error:cds-all:Header/UnsupportedVersion.
This host does NOT serve /energy/plans, it returns an nginx HTTP 404, which matches the behaviour of AGL, Alinta and Origin
Energy and reflects the CDR energy design in which generic tariff data is centralised at the Australian Energy Regulator
rather than held by each retailer.

to the shared Consumer Data Standards energy contract. NOT anonymously verifiable and deliberately listed without a base
URL. The CDR InfoSec and resource base URIs for a data holder are published only through the authenticated portion of
the CDR Register and are reachable only by an ACCC accredited data recipient presenting a client certificate. Access requires
ACCC accreditation, OAuth2 / OpenID Connect under the CDR FAPI profile, mutual TLS, and explicit consumer consent. Recorded
here as designated and documented, not as an endpoint confirmed by API Evangelist.
