HONOLULU (AP) - Hawaii is exploring ways to improve the security and resiliency of Oahu's electrical grid.
The state Department of Defense on Friday said it's working with Hawaiian Electric, IBM, U.S. Pacific Command and other entities on a study that will come out in May.
Researchers will analyze weather pattern data to better understand how cloudy days and lack of wind will affect the power supply. This is becoming more important as the island generates more electricity with solar panels and wind turbines.
They'll also strive to understand how to better protect the grid from attacks like one that hit Silicon Valley last April.
In that incident, unidentified individuals fired shots into a power plant substation, causing outages. They also snipped fiber-optic lines to knock out phone and 911 services.
