India's data-centre boom is no longer about announcements. It's about which substation will actually give you power, when, and at what landed cost. Gridvik compiles 62 projects (facilities, programmes & financing) into one source-linked dataset — every row with exact URL, announcement date and confidence 1–3 — and adds the Power & Approvals Layer you can't scrape.
Press says 130 MW. The 220kV feeder has 45 MW headroom and a 60 MW sanctioned grant dated 14 Aug 2026. That’s the decision. We track it weekly.
Below is the Power & Approvals field list. Every field is delivered as: value | source URL | last-checked | confidence 1–3 | change date. Derived fields (TTP, landed cost) are proprietary — inputs are public, logic is ours.
Helps: funds avoid $30-100M mis-allocation; operators pick district — not just state.
Helps: funds underwrite incentive NPV — not hope; operators time their MoU → land → power sequence.
Helps: vendors time the 24-mo calendar — the column that pays for the subscription.
Needs reading CTUIL grant registers, SLDC filings, DISCOM ARR + tariff orders, state G.O.s and single-window portals — manual work that is hard to automate reliably. This level of India-specific, project-level power detail is rare in global trackers. The longitudinal diff compounds — early data matters — the archive compounds over time.
Below is a real-structured sample (not a mock) — same schema ships Monday. Source URL + last-checked on every field.

Decision: commit $30-100M to this site vs its 3 alternatives?
Needs: TTP + sanctioned + ISTS exposure + incentive NPV (disbursed, not promised).
Buys: Team $18K + Diligence $20-40K.
Decision: Siruseri vs Ambattur vs OMR?
Needs: headroom by feeder + STU queue + OA landed cost.
Buys: Team $18K + State Pack $3.5K (TN).
Decision: which 10 projects to chase next 4Q?
Needs: procurement window + decision-maker + grant awarded alert.
Buys: Vendor Pipeline $15-30K/yr.
