Pacific Gas and Electric Company (PG&E) is actively monitoring a potential high wind event forecasted to impact several regions within its service area starting Wednesday, July 15, 2026. The utility is preparing for a Public Safety Power Shutoff (PSPS) across portions of 10 counties to mitigate wildfire risks driven by high winds, low relative humidity, and dry fuel loads. This planned de-energization represents the third PSPS event of the 2026 calendar year. For energy executives and grid operators, this event highlights the ongoing operational challenges of managing infrastructure during volatile weather patterns and the critical role of proactive de-energization in wildfire prevention and grid resilience.
High Wind Forecast and Targeted County Impacts
The weather event is expected to reach targeted service areas at approximately 1 p.m. on Wednesday, July 15. PG&E is tracking conditions that span the North Bay, South Bay, East Bay, Salinas Valley, San Joaquin Valley, and the Central Coast. The utility has already activated its Emergency Operations Center (EOC) and initiated advanced notifications to customers in high-risk zones as of Tuesday, July 14.
The anticipated PSPS is expected to affect approximately 7,800 customers across 10 specific counties. The distribution of affected customers is concentrated in Monterey (3,083), Marin (2,017), and San Luis Obispo (1,978). Other impacted areas include Santa Barbara (287), San Benito (154), Alameda (75), Contra Costa (70), Merced (77), San Joaquin (33), and Fresno (17).
PG&E notes that the scope of these outages remains fluid; de-energizations may be delayed, cancelled, or expanded based on real-time weather developments and field conditions. The duration of any resulting outages will depend on weather stability and the time required for patrols and inspections to identify and repair wind-related damage. This proactive stance is necessitated by the fact that powerlines often traverse high-risk regions with extreme wind and low humidity, even if local neighborhood weather appears relatively mild.
Wildfire Mitigation and PSPS Program Evolution
This upcoming event follows a trend of early fuel drying in parts of the service area, driven by very dry weather observed in March. PG&E utilizes PSPS as a "tool of last resort" to prevent catastrophic wildfire spread. The utility cited a Technosylva fire spread simulation regarding a previous event in May 2026, which suggested that failing to initiate a PSPS could have resulted in up to 270,000 acres being impacted by wildfires.
To minimize the economic and social disruption caused by these shutoffs, PG&E has implemented several infrastructure and technological improvements. These include the deployment of energy storage systems to maintain critical services, new technologies designed to reduce the number of customers affected, and ongoing system upgrades such as undergrounding lines.
The efficacy of these mitigation strategies is reflected in historical data. In 2019, PSPS events affected more than 2 million total customers. By 2025, the utility reported that the number of customers impacted by such events had dropped significantly to approximately 18,000. These improvements, alongside expanded Community Resource Centers (CRCs) and automated notification systems, aim to balance public safety with grid reliability.
Key Takeaways
- PG&E expects to affect approximately 7,800 customers across 10 counties starting July 15, 2026, due to high winds and low humidity.
- The utility has activated its Emergency Operations Center and is utilizing advanced notifications to prepare for the third PSPS event of 2026.
- Historical data shows a significant reduction in PSPS impact, dropping from over 2 million customers in 2019 to approximately 18,000 in 2025.
EnergyInsyte's Take
In our view, this upcoming PSPS event underscores the persistent volatility of the California grid and the necessity of sophisticated, data-driven de-energization protocols. While the scale of this specific event—affecting 7,800 customers—is relatively small compared to historical peaks, the fact that this is already the third PSPS of 2026 signals an early and aggressive fire season driven by March's dry conditions.
This signals that the utility's shift toward targeted, technology-led mitigation is working; the massive reduction in customer impact from 2019 to 2025 demonstrates that capital deployment into energy storage and system undergrounding is yielding measurable reliability benefits. For grid operators and investors, the takeaway is clear: wildfire risk management is no longer just about reactive repairs, but about the precision of predictive modeling and the ability to execute localized, proactive shutdowns to protect long-term infrastructure assets.
