Public Safety Power Shutoffs (PSPS) on Oʻahu

---

The Hawaiian Electric Company’s (HECO) Public Safety Power Shutoff (PSPS) program is a method of wildfire prevention that involves temporarily turning off the power to certain high-risk areas during extreme and potentially dangerous weather conditions. Typically, those weather conditions involve strong winds, low humidity and very dry vegetation — all of which can elevate the risk of wildfire.

In extreme weather conditions, HECO’s power lines are more susceptible to damage from wind and debris, and damaged lines can spark wildfires when humidity is low and vegetation is dry. By turning off the power in high-risk areas during extreme conditions, HECO is reducing the likelihood that a damaged power line will cause a wildfire.

The decision to implement a PSPS is made by HECO, not by the City and County of Honolulu, and will only be made “as a last line of defense to help protect communities,” according to the utility.

Which neighborhoods are affected by a PSPS?

HECO has identified specific areas that have high wildfire risk that may be subject to a public safety power shutoff. In any of the areas in orange seen on the map below, HECO may decide to preemptively turn off the power during periods where severe weather conditions, including strong winds and dry vegetation, result in an increased risk for wildfires. A PSPS could impact the entire area or only selected segments depending on conditions.

How does a PSPS impact me?

HECO’s decision to implement a public safety power shutoff will result in the electricity being turned off for residents and businesses within certain geographic areas determined to be most at-risk. Depending on how long the dangerous weather conditions persist, these power outages could last anywhere between several hours and several days.

How does a PSPS impact the Board of Water Supply (BWS)?

BWS operations – pumping and transporting water – rely on the commercial power delivered by HECO. If and when activated, a PSPS will affect BWS operations on the Leeward Coast. Back-up power plans are in place to maintain potable water supply to the affected water system as long as possible during a PSPS event. We ask all customers to practice water conservation to ensure sufficient water supply for drinking, sanitation, and emergency purposes.

How will I know a PSPS is happening?

HECO customers will receive PSPS notifications via emails, phone calls, texts, social media updates, mobile app notifications, and news releases. Local media outlets, including television and radio stations and newspapers, will also disseminate information after it has been released by HECO. Once HECO has made the decision to implement a PSPS, the City and County of Honolulu will utilize the HNL.info alert system and social media updates to notify residents.

How can I prepare for a PSPS?

The decision to implement a PSPS could happen quickly, with little or no notice, depending on the severity of weather conditions. Residents and business owners within the PSPS area should stay prepared by:

• Make and update your emergency plan, so that everyone in your household knows what to do in the event of a PSPS outage. Having an up-to-date emergency plan is especially important for anyone with urgent medical needs, including medical devices that require electricity to operate.
• Build an emergency kit – like you would for a hurricane or tsunami – that has enough non-perishable food, water and medication to last through an extended outage. Since gathering your belongings would be more difficult when the power is out, also make sure you have an evacuation go bag prepared in the event there is an emergency evacuation.
• Contact your doctor or pharmacist on how to handle emergencies and power outages if you or someone in your care has a condition that requires medication pumps or life support systems, or if your medications require refrigeration. Fill out HECO’s medical needs communications form to make sure the utility knows if anyone in your household is on life support or requires immediate care in the event of a power outage.
• Monitor weather conditions and be responsive to emergency notifications from HECO, the City and County of Honolulu and other emergency responders. Download the HNL.info and/or HECO mobile apps and sign up for updates.
