A cyberattack on the U.S. energy grid has just come to light, so to speak, which disrupted plant visibility at Utah-based sPower back in March.
sPower, a Utah-based wind and solar provider, began experiencing a series of lost connections between its main control center and remote power-generation sites. The brief, intermittent periods of downtime were determined to be the result of a denial-of-service (DoS) attack, according to documents obtained via the Freedom of Information Act (FOIA) by E&E News, a utility-industry trade publication. That operational disruption makes the attack the first of its kind in the country.
