Provenance Record

Clear, well-structured News piece (607 words, within the 400-1200 News range). Standard Overview / What We Know / What We Don't Know / Analysis format. Technical specifics (power/energy ratings, duration, financing structure) are precise and the 'What We Don't Know' section honestly flags undisclosed terms (cell supplier, contract price, round-trip efficiency, dispatch arrangement).

All three source snapshots read from disk and verified. source-0.html.gz (Energy-Storage.News, allowlisted, 200): confirms verbatim the 250MW/1,000MWh Pediment rating, Mesa / Elliot Road Technology Corridor location, June 16 announcement, Eolian 2024 acquisition, 'first of two contracted projects', $398M financing closed Dec 2024 led by Société Générale with ING Capital and Bank of America, the second 250MW/2,000MWh BESS due December 2028, and the SRP busy-June context (Flatland 200MW/800MWh with EDP Renewables on June 9; Energy Dome 19MW/190MWh in St. Johns on June 15). source-1.html.gz (PR Newswire, allowlisted, 200): confirms the $398M financing, 'Blackstone portfolio company' description, Société Générale/ING Capital/Bank of America arrangers, and the $16M direct economic impact / $14M property tax to Maricopa County over the first 20 years. source-2.html.gz (media.srpnet.com, NOT on allowlist, 200): confirms verbatim the 'up to 56,250 Valley homes for four hours' figure, the Bobby Olsen quote and his title (SRP Associate General Manager and Chief Power System Executive), the Moe Hajabed quote and his title (CEO, Aypa Power), and the decarbonization targets (82% carbon-intensity reduction from 2005 levels by 2035, net zero by 2050). No headline, summary, or Overview-lead claim rests solely on the non-allowlisted srpnet.com source — all lead-level claims trace to Energy-Storage.News.

All headline/summary/lead numbers, names, dates, and quotes trace to the source carrying them. ONE misattribution: the article writes 'Aypa said the project created over 200 construction jobs and is expected to deliver over $16 million in direct economic impact... according to the [financing announcement]' (source 1, PR Newswire). The '$16M / $14M / Maricopa / 20-year' portion IS in source 1, but the 'over 200 construction jobs' figure is NOT in source 1 — it appears in source 0 (Energy-Storage.News, attributed to SRP) and source 2 (the SRP release). The jobs figure is true and verifiable within the article's own cited sources; only the in-line citation points to the wrong outlet. This is a subordinate body claim, recoverable via a corrections note. Olsen's title is rendered with a trivial possessive ('SRP's' vs source 'SRP') — not a misattribution.

Accurate, neutral, well-sourced News piece. Every headline/summary/lead claim is backed by the allowlisted Energy-Storage.News source. One subordinate body claim (200 construction jobs) is cited to the wrong outlet within the article's own source array, and the srpnet.com primary source is off-allowlist; both are honestly covered by a single corrections record.
