The Australian grid carbon intensity feed.

A wholesale, programmatic source of real-time and historical grid carbon intensity (tCO₂e/MWh) for every NEM region and WA. Built for sustainability SaaS platforms that need accurate Australian Scope 2 numbers without standing up an AEMO ingest pipeline themselves.

What you get

• Per-region intensity for NSW1, VIC1, QLD1, SA1, TAS1 and WA1 — refreshed every 30 minutes from AEMO SCADA + WEM.
• Up to 7 days of history per request, query window configurable in hours.
• GHG-Protocol-aligned methodology— derived from actual generation mix and DCCEEW emission factors, the same engine powering gridIQ’s ASRS-aligned Scope 2 product.
• Bearer-token auth using the standard Authorization: Bearer giq_... header.
• Attribution-required— display “Powered by gridIQ” near any visible derived value.

Pricing

Already on the Watt API? Carbon Intensity is included in every Watt API tier — your existing Bearer key already works.

Who buys this

Sustainability SaaS platforms (Watershed, Persefoni, Sweep, Greenly, Plan A, etc.) typically derive Scope 2 emissions for their customers using country-level grid factors. Australian customers get a more accurate, time-matched answer when the platform consumes a live per-region feed — and Australian audit committees increasingly expect it.

Embedding gridIQ’s Carbon Intensity API gives every Australian customer of your platform an accurate, AEMO-derived intensity value without you needing to build (and maintain) the ingest pipeline.
