Rodman introduces the concept of a common mode failure, the nightmare scenario in which identical components from the same manufacturer fail simultaneously across multiple regions, defeating the grid's built-in sector isolation. He reveals that NERC's official plan calls for operating the grid in a precautionary mode during a critical transition period around the year 2000 rollover, reducing power transfers between utilities and bringing older generation equipment online as backup.
Art presses Rodman on whether January 1, 2000 will be a good day or a bad day. Rodman answers that it depends on where you live, noting that midwinter weather emergencies could compound any technical failures. Callers share early Y2K glitches already surfacing, including Social Security phone outages and taxi meter failures in Singapore.
Key Moments
NERC's report admits the grid has caught a bug: Rodman walks through the North American Electric Reliability Council's published assessment. NERC frames Y2K as a unique threat, and Rodman concedes the grid has, in his phrase, contracted a bug. He warns the bitter medicine plan to find vulnerable date-sensitive parts is necessary because Y2K is, very definitely, a real problem in the power grid.
Common-mode failure: the continent-wide blackout scenario: Rodman explains the worst-case Y2K mechanism in the North American grid. Because 200 bulk energy providers buy electronic relay components from the same small pool of vendors, a single date-sensitive part embedded across Nevada, Texas, Florida, and Quebec could fail simultaneously, defeat the regional fail-safe boundaries, and produce a full continent-wide blackout.
