Track the power equipment, permits and dated evidence behind data centers. See what each record establishes, and what remains unknown.
A third-party inventory of proposed behind-the-meter gas plants—not BTW-verified operating capacity. We publish it as a comparison layer so the gap is inspectable rather than rhetorical.
Reported means a source lists a project and capacity. It does not mean financed, permitted, built, or operating.
Capacity bases differ by disclosure, and 4 projects have no published capacity. The total must not be added to the verified fleet.

Document events use the document date. A record review is dated when BTW checked the source and describes only the scope reviewed.
Every dot is a published operating facility. Position and capacity come from the same permit and evidence trail as the fleet table.
Projects under research do not appear here until their coordinates, capacity and status have passed review.
3 published facilities. MW describe the equipment cohorts supported by the linked records. Permit ratings and historical observations do not establish current delivered power or complete site capacity.

A permit date, a campus opening and the first delivery from a particular power plant are different milestones. We publish an interval only when both endpoint fields carry receipts.
Legacy dates remain available in the dataset for traceability. Missing endpoint receipts keep them out of this calculation.
Fuel by heat rate, capex annualized over 15 years at 10%, O&M — against your grid tariff, and against the value of connecting earlier. Use illustrative scenarios or set your own assumptions.
All presets are illustrative assumptions, not measured facility economics or live market prices. The Abilene permit provides equipment context; it does not establish every slider value. Gas and grid inputs can be checked against EIA gas data and state industrial averages. Earlier-operation value uses revenue × your incremental contribution margin. Include all costs other than the separately modeled power premium in that margin to avoid double counting. Results exclude discounting, taxes and any costs you have not included.
Link to this scenario · Bookmark or copy the link to revisit these assumptions.
Inspect the named developers, offtakers and equipment in published records. Missing participants remain unknown.
Follow equipment and permit changes in your target projects. A filing can identify participants; it does not establish that a supply contract is still available.
Inspect source documents, compare documented equipment and explore power-cost assumptions. Exact operating dates and project economics require their own evidence.
Numbers you can print, with the government document one click away on every row. CC BY 4.0 — quote freely, chart freely, just credit the source.
Every row links to the government document it came from. Here's the pipeline — and what a source actually looks like.
A successful source sweep is a retrieval check, not a new verification of every facility fact. Registry snapshots and complete permit documents have different coverage.

Every number on this site comes from public records — air permits, siting dockets, court filings. Your taxes funded their creation. The data was just scattered across fifty agencies in formats nobody could read.
We collect it, verify it, and structure it. The dataset is free to download and always will be — CSV, JSON, API, no signup wall. Use it in your research, your models, your reporting. All we ask is attribution.
One day we may build paid services on top. The underlying data stays open. That's the deal, in writing.
Project records, equipment evidence and a transparent cost model for your next research question.
Dated project milestones, an Abilene before-and-after example and the next records to check.
Abilene's source-linked power record and a clearly dated Texas announcement inventory.
Read the Abilene permit: unit counts, site ratings, changes and limits of the evidence.
Compare gas generation with a grid tariff. Change assumptions and share a reproducible scenario.
Reconcile announced, permitted, installed and delivered MW using real project records.
Agree the projects, sources and fixed fee before four weeks of focused research begin.
A dated sample showing what changed, what is confirmed, what is unknown and what to check next.
Published updates on new filings, documented equipment and what they mean. The data is free for everyone. The interpretation arrives by email first.
