Following a performance audit conducted between September 2019 and March 2021, GAO has discovered that the electricity grid’s distribution systems are increasingly vulnerable to cyber-attacks and that the potential impact of such attacks is not yet clear.
According to GAO, the Department of Energy (DOE), the lead agency for the energy sector, hasn’t included in its plans for the grid’s cyber-security the necessary measures to fully address risks to distribution systems. DOE has updated its plans following a 2019 GAO report on grid cyber-security issues.
