ENTERPRISE API · CARBON ACCOUNTING
15-minute, state-level grid carbon intensity for India — and the hourly-matching engine that uses it.
India's grid carbon factors have been poorly characterised at granular spatial and temporal resolution. There is no equivalent of Electricity Maps for India — no 15-minute, state-level, audit-grade carbon intensity API. Annual paper-matching for corporate RE claims hides the truth: a company with a daytime solar PPA can still consume coal-heavy power in evening peaks. The Time-Block Carbon API publishes two strictly separated signals — a location-based average for Scope 2 reporting and an operational marginal signal for load shifting — with a full audit trail back to the underlying RLDC, NLDC, IEX, and CEA snapshots.
WHAT IT DOES
Three jobs, one contract
Two signals, never mixed
Average and location-based for Scope 2 disclosure. Operational and marginal for load-shift dispatch and battery operation. Each value is tagged with its signal type at the schema level so a client cannot accidentally report a marginal value as a Scope 2 number.
24/7 hourly matching for any load and any RE contract
Send a 15-minute load profile and a contracted RE generation profile. Receive the time-matched clean-power percentage, an unmatched-block ledger with the carbon impact of each unmatched 15-minute block, and recommended load-shift windows that maximise carbon savings without breaking demand.
Audit-ready by design
Every response is replayable from the stored grid-mix snapshot for that block. Historical restatements carry a restated_from block. Source citations on every value. The artefact a BRSR reviewer or a CBAM auditor needs.
WHY NOW
The window
BRSR is mandatory for the top 1,000 listed Indian companies. CBAM exposure is real for steel, aluminium, cement, and fertiliser exporters. Hyperscaler 24/7 commitments now apply to their India operations. The Green Hydrogen Mission requires hourly RE matching for certified green hydrogen. ESG platforms — Sweep, Watershed, Persefoni, IBM Envizi — need an India data spine, and currently have none.
SAMPLE
See the call
A hyperscale data centre in Hyderabad, asking for the 24/7 match against its 200 MW load profile and a contracted 350 MW Andhra Pradesh solar PPA, returning a 47 percent hourly match with a recommended evening load-shift window of 18:00–21:00.
