Conesville Unit, central Ohio (375MW) A generator trip happened at 12.05 Greenwood Unit, north of Detroit Generator trip at 1:14 Eastlake Unit (597MW), Northern Ohio Generator trip 1:31 Stuart Atlanta (345kV) Transmission disconnect at 2PM, because a brush fire shorted the conductors Harding Chamberlain Transmission line disconnect at 3PM Hanna Juniper Transmission line disconnect at 3.30PM The Hanna Juniper line hit a tree, and that caused a short circuit to ground and the line disconnected. An acorn fell of the tree, hit Chicken Little on the head, and she went off to tell the rest of her mob that the "sky was falling down" as Adamson Rust puts it in his rather non technical description. Star South Canton Transmission line disconnect at 3.40PM Canton Central Tidd Disconnect at 3.45 Samnis Star Disconnect at 4PM Galion Ohio Central Muskingum Disconnect at 4.08PM East Lima Fostoria Central Disconnect at 4.10 Kinder Morgan Disconnect at 4.10 At this point, says Marty, power flows from Indiana and over the west-east Michigan transmission loads started to feel the strain, while at around ten past four, the Eastern Interconnection frequency showed a demand loss of between 700 to 950MW. The following sequences happened almost at the same times. Harding Fox Disconnect 4.10 Lake Erie Twenty generators stop at 4.10PM West-East Michigan Disconnect Midland Cogeneration Venture Disconnect Detroit Transmission system northwest of Detroit goes down Perry Ashtabula Erie West 4.10PM, transmission line cuts northern Ohio off from Pennsylvania The investigators at this point reckon that when the lines along the south of Lake Eyrie fell, the power reversed direction and started going in a counterclockwise loop heading from Pennsylvania to NY, to Ontario and into Michigan. Homer City to Watercure Road 4.10PM a disconnect Homer City to Stalle Road 4.10PM a disconnect South Ripley to Dunkirk 4.10PM a disconnect East Towanda to Hillside 4.10PM a disconnect Exceedingly heavy power flows heading towards the New York and New Jersey lines. Fostoria Central Galion Down at 4.10PM Perry I Nuclear unit This 1252MW unit disconnected off at 4.10PM Avon Lake 9 Off line Beaver-David Besse Cleveland load auto disconnected Campbell Unit Three Disconnect Keith Waterman Disconnect 4.10PM Wawa Marathon Disconnect 4.10PM Branchburg Ramapo Down 4.10PM The Eastern Interconnect was divided into two sections. New York split east west 4.10 Transmission lines disconnect. New England becomes an electricity island for a while New York split continued 4.10PM. Northern New Jersey and south west Connecticut stay attached to New York system east. Ontario, east Michigan stays connected to New York West Ontario, New York separate at Niagara Falls 4.10PM Long Mountain, Plum Tree disconnect 4.11PM Ontario, east Michigan Separation 4.12PM Eastern New York blacks out with small pockets of power left. Western New York manages to support 50% of load.
