IPPData methodology

IPPData publishes a transparent, source-backed database of Independent Power Producers (IPPs), renewable platforms and clean energy developers. This page explains exactly what we count, how we count it, and how to read every number on the site.

What counts as an IPP

An IPP is any company or platform whose material activity consists of developing, owning, financing, operating or co-operating electric generation assets and selling that energy through PPAs, auctions, bilateral contracts, spot markets or combinations of these. We include private companies, listed groups, utility-affiliated platforms and state-controlled platforms when their competitive generation activity is material.

We do not include pure TSO/DSO operators or fully regulated utilities without material IPP activity. Equipment manufacturers without generation ownership are also excluded.

Capacity definitions

• Operational capacity (Op) — Plants currently producing power.
• Installed capacity — Often used interchangeably with operational; we follow the company's own wording.
• Gross capacity — Nameplate at 100% basis, not adjusted for ownership share.
• Net capacity — Capacity net of co-owned shares.
• Consolidated capacity — As reported under accounting consolidation.
• Equity / attributable / pro-rata capacity (Att) — Adjusted for the company's ownership share of each asset.
• Secured capacity (Sec) — Operational plus signed contracts and projects under construction.
• Pipeline / development pipeline — Projects in development but not yet RTB or under construction.
• RTB pipeline — Projects that have all permits and are ready to build.
• Portfolio size (Port) — Total of operational, under construction and disclosed development pipeline.

Basis codes

Every capacity metric on the site carries one of four basis codes:

• Op — Operational/installed capacity.
• Att — Attributable, equity or pro-rata capacity.
• Sec — Operational plus secured/under-construction or contracted assets.
• Port — Total portfolio including development pipeline.

Technology classification

• Solar PV and CSP (concentrated solar) are tracked separately.
• Onshore and offshore wind are tracked separately.
• Hydro and pumped storage are tracked separately. Mini-hydro is grouped with hydro unless the company discloses otherwise.
• BESS MW (power) and MWh (energy) are tracked separately and never mixed.
• Gas, coal and oil are tracked for context but never aggregated into "renewable capacity".

Ranking rules

• Renewable installed ranking uses operational or installed renewable capacity (Op/Att). Portfolio-only companies are excluded.
• Platform ranking allows Sec and Port figures but the basis is always shown.
• Storage ranking separates BESS from pumped storage.
• Solar ranking uses solar PV capacity in whatever basis the company discloses; basis is always labelled.

Confidence scoring

• High — Primary source with a clear date and a clear, comparable metric.
• Medium — Primary source but mixed perimeter or limited freshness, or recent secondary source corroborated by multiple references.
• Low — Partial data, single press article, older than 18 months, inferred figure or non-comparable perimeter.

Source hierarchy

1. Annual reports and quarterly results.
2. Investor presentations.
3. Regulatory filings.
4. Company press releases.
5. Reuters and credible financial press.
6. Secondary industry media.
7. Reference sites (Wikipedia) — used as secondary only.

Update cadence

Profiles are reviewed continuously. Quarterly results, annual reports and material corporate events trigger updates. The "Last updated" date on each profile reflects the latest manual review.

Reporting corrections

Every profile has a Report a data issue link. If you have access to a primary source that improves a figure on the site, please share it — we'll add it to the source list and update the metric with full attribution.

What we are not

IPPData is not a substitute for project-level project finance databases, league tables or transactional intelligence. The launch profiles are a foundation, not the full universe. The Top 100 watchlist is being normalised one company at a time; provisional rows are not published as ranked entries until they have been re-sourced inside the IPPData schema.
