Editor Notes

Content Quality:

The rewritten article is well-structured and informative. All key statistics are clearly presented with appropriate context. The 564-word count falls comfortably within the News category range (400-1200 words). The article covers a genuinely newsworthy EIA forecast with appropriate specificity across solar, storage, wind, and gas capacity additions.

Source Verification:

All three sources were reachable and verified by the automated pipeline. EIA (eia.gov) is a U.S. federal government agency and the definitive primary source for U.S. energy data — its absence from the allowlist is a gap in the allowlist configuration, not a credibility concern. PV Magazine USA is a widely-cited industry trade publication. Enerdata is a specialized energy data analytics firm. The sources are appropriate for this topic. Recommend adding eia.gov to config/source_allowlist.txt.

Factual Accuracy:

The required correction from the first review was applied correctly. The previous submission erroneously described 2025 as a record year for utility-scale solar ('itself a record at the time') and characterized 2024 and 2025 as 'back-to-back records.' Both errors have been removed. The rewritten text now accurately states '2025's 27.2 GW — well above the prior record of 30.8 GW set in 2024,' which correctly reflects the EIA primary source. The section heading was also corrected from 'Solar Leads for a Third Consecutive Record Year' to 'Solar Surges Past the 2024 Record.' All numerical claims (86 GW total, 43.4 GW solar, 24.3 GW storage, 11.8 GW wind, 6.3 GW gas, 53 GW in 2025, geographic percentages, named project capacities) are consistent with the cited sources. The interconnection backlog framing is accurate and appropriately qualified.

Overall Assessment:

APPROVE. This is a clean, well-reported News article based on a primary government source. The rewrite successfully addressed the single required correction. All automated checks pass. The article is ready for publication.

ERROR Factual Accuracy

Inaccurate claim that 2025 was a solar record year

The article states '2025's 27.2 GW — itself a record at the time' and describes '2024's 30.8 GW and 2025's 27.2 GW as back-to-back records.' However, the EIA primary source (https://www.eia.gov/todayinenergy/detail.php?id=67205) shows 2024 (30.8 GW) exceeded 2025 (27.2 GW). Therefore, 2025 was NOT a record year for utility-scale solar — 2024 was the record year, and 2025 saw a decline. The framing of 'back-to-back records' and '2025 a record at the time' is factually incorrect. The pv-magazine source describes 2025 as record-setting but does not provide 2024 data to support this; the EIA primary source contradicts it. The article must not repeat a secondary source's framing that conflicts with the authoritative primary source.

Editor Notes

Content Quality:

Well-structured and clearly written. Good use of specific statistics, geographic breakdowns, and named projects. Word count (560 words) is appropriate for a News article. The grid interconnection section adds important analytical context.

Source Verification:

All three sources verified as reachable. The EIA primary source (eia.gov) is a U.S. federal government agency and highly authoritative. The pv-magazine USA and Enerdata sources are specialized energy publications. None are in the current allowlist, but eia.gov is a .gov domain and should be added. The sources are correctly cited throughout the article, though one attribution detail is noted below.

Factual Accuracy:

Critical issue found: The article states '2025's 27.2 GW — itself a record at the time' and describes '2024's 30.8 GW and 2025's 27.2 GW as back-to-back records.' The EIA primary source explicitly shows 2024 at 30.8 GW exceeded 2025 at 27.2 GW — meaning 2025 was NOT a record year for utility-scale solar additions. The pv-magazine secondary source misleadingly describes 2025 as record-setting (possibly combining utility-scale and distributed solar, or in error), but the bot relied on this framing without cross-checking against the EIA primary source which it also cites. Other statistics (86 GW total, 43.4 GW solar, 24.3 GW storage, 11.8 GW wind, 6.3 GW gas, Texas 40% solar, 53% storage) verified as accurate from the EIA source. The Arizona/California 6% solar stat is correctly from EIA (not Enerdata as implied by attribution order) but the data itself is accurate. Wind project capacities (SunZia 3,650 MW, Vineyard Wind 800 MW, Revolution Wind 715 MW) confirmed in EIA.

Overall Assessment:

Strong, well-reported article with accurate core statistics and excellent source usage. One factual error regarding the 2025 solar record claim must be corrected before publication. The error is specific and fixable in a targeted rewrite.
