Sudden Jefferson Parish Blackout: 9,300+ Entergy Customers Left in Dark as Cause Remains Unknown

25 October 2025

Outage Scope: More than 9,300 Entergy customers in Jefferson Parish lost power Friday night, Oct. 24. The outages hit communities on the West Bank (Jean Lafitte, Estelle, Barataria) and parts of Kenner ^[1] ^[2]. Entergy’s live outage map showed 9,369 customers affected (with 9,353 in the Jean Lafitte area) ^[3] ^[4].
Restoration Efforts: Crews worked through the night. Entergy estimated full restoration by ≈11:00 PM Friday ^[5]. Updates directed customers to Entergy’s outage portal for progress. No injuries or damage reports have been announced.
Unknown Cause: Entergy has not yet identified a specific cause. Company spokesman simply said crews are “working to make repairs as quickly and safely as possible” ^[6]. Weather was calm locally at the time, and no severe storms were reported, leaving the trigger unclear.
Regulatory Scrutiny: Louisiana’s grid reliability has been under intense review. A recent legislative audit warned that Louisiana has “one of the least reliable electric grids in the country,” with outage frequency up 14% and duration up 50% over the past decade (excluding big storm events) ^[7] ^[8]. Local leaders note this outage comes on the heels of other regional blackouts (e.g. a May 2025 event that darkened ~100,000 customers in New Orleans/BR) and have demanded answers ^[9] ^[10].
Expert Comments: Entergy and state officials blame geography and infrastructure. An Entergy spokesman noted “Louisiana is exposed to many natural risks… [with] poles set in marshes… Louisiana also has frequent and intense lightning and severe thunderstorms” ^[11], saying those factors “consistently challenge electric reliability.” Public Service Commissioner Davante Lewis added bluntly, “we haven’t diversified power sources to generate electricity in Louisiana” ^[12], highlighting the state’s heavy reliance on natural gas.
Financial Impact: Entergy Corporation (NYSE: ETR) – the parent utility – actually trades near $96 per share amid this news ^[13]. Analysts remain bullish: Wall Street consensus is a “Moderate Buy” with price targets in the high-$90s ^[14]. Notably, JPMorgan recently lifted its Entergy target to $103, reflecting confidence that grid investments and monopoly status will support long-term earnings ^[15].

With that, crews continued working through Saturday. Entergy and regulators say the outage underscores the urgency of grid upgrades. Federal infrastructure grants (Louisiana is slated to receive ~$1.2 billion for power grid modernization by 2030 ^[16]) and Entergy’s own investments (about $2 billion in hardening since 2020 ^[17]) are cited as key to preventing future blackouts. Customers are advised to watch Entergy’s official outage map and local news for the latest restoration updates.

Is Enbridge Stock a Buy After Its 2025 Results? Key Takeaways on Risks and Dividend Outlook
December 25, 2025, 8:29 PM EST. Enbridge (TSX:ENB) reported solid 2025 results and reaffirmed 2026 guidance of about 3% growth in DCF and 4-6% growth in EPS, yet the stock slipped roughly 3% as geopolitical tensions and oil-price moves kept investors on edge. If Russia-Ukraine peace talks ease sanctions, oil could glut, pressuring prices and Enbridge's export-driven margins. Tariffs on Canadian oil earlier in 2025 shaved volumes to the U.S., though Enbridge navigated the hit by relying on long-term contracts and tolls. The core positives remain: protected cash flow, a dividend with a sustainable payout ratio of roughly 60-75% of DCF, and ongoing capital expenditure to grow LNG export capacity. In the short term, volatility will ride on geopolitics; in the long term, Enbridge's cash flow and dividend outlook appear resilient, albeit with tempered growth.
