Oil kept unwinding from the Saudi-pipeline spike — a secondary-sourced $92.41/bbl on Sep 25 versus last week's EIA-confirmed $107.02/bbl on Sep 15 — while the week's more durable story sat in residential storage: Sunrun and Tesla coordinated a record 580 MW distributed-battery dispatch to California's grid on a single heat-wave evening, the national solar-plus-storage attachment rate climbed to 46% even as new installations are set to fall, and CATL's planned gigawatt-hour-scale sodium-ion delivery start landed the same week the industry held its first dedicated sodium summit. The throughline: the home is becoming a genuine grid asset — coordinated by aggregators, priced by falling LFP costs, and now getting a second chemistry option — right as policy quietly widened the pool of homes eligible for the credit that helps pay for it.

Oil's unwind deepens to a ~14% pullback; gas and crude inventories both build
Secondary market-data aggregation places WTI around $92.41/bbl on Sep 25, down from the prior week's EIA-confirmed $107.02/bbl print on Sep 15 — a roughly 14% retreat over ten days that extends last week's "early unwind" read into a fuller normalization from the Saudi-pipeline spike (Trading Economics; Fortune market recap). Henry Hub told a similar story, trading near $2.88/MMBtu as of Sep 21 versus the prior week's EIA-confirmed $2.97/MMBtu, with the EIA's own August outlook already trimming its full-year 2026 forecast from $3.67 to $3.44/MMBtu.
Both gas storage and crude inventories posted builds inside the window: EIA's Weekly Natural Gas Storage Report (week ended Sep 18, released Sep 24) showed a +53 Bcf build to 3,351 Bcf — stronger than the prior week's +44 Bcf — while the Weekly Petroleum Status Report (same release date) showed commercial crude inventories building 3.0 million barrels to 426.4 million, about 2% above the five-year average. Neither figure suggests tightness; this is a market normalizing on both the price and physical-supply sides at once.
• WTI: ~$92.41/bbl on Sep 25 (secondary aggregation) vs. $107.02/bbl EIA-confirmed on Sep 15 — [NEED: source] for direct EIA-series confirmation.
• EIA gas storage: +53 Bcf build (week ended Sep 18) to 3,351 Bcf — 95 Bcf above the five-year average, 146 Bcf below year-ago levels.
• EIA crude inventories: +3.0 million barrels to 426.4 million (week ended Sep 18) — ~2% above the five-year average.
