Another timeline from CNN:

(AP) -- A timeline from the joint U.S.-Canadian task force investigating the August 14 blackout. It uses information from the North American Electric Reliability Council (NERC), Independent System Operators, utility companies and regulatory agencies in the United States and Canada.

Generators shut down:

1:31 p.m. -- FirstEnergy's Eastlake power plant in northern Ohio.

Transmission lines disconnect between eastern and northern Ohio:

3:05 p.m. -- FirstEnergy's Harding-Chamberlain line goes out of service, reason unknown.

3:32 p.m. -- FirstEnergy's Hanna-Juniper line disconnects after contact with a tree.

3:41 p.m. -- Star-South Canton line, shared by AEP and FirstEnergy, disconnects.

Transmission lines into northwestern Ohio disconnect; generation interrupted in central Michigan:

4:08-4:09 p.m. -- AEP's Galion-Ohio Central-Muskingum and East Lima-Fostoria Central transmission lines disconnect.

4:09 p.m. -- Kinder Morgan's generating unit in Central Michigan.

Transmission lines disconnect across Michigan and northern Ohio; generation interrupted in northern Michigan and northern Ohio; northern Ohio separates from Pennsylvania:

4:10 p.m. -- Twenty generators along Lake Erie.

4:10 p.m. -- West-east Michigan lines.

4:10 p.m. -- Midland Cogeneration Venture.

4:10 p.m. -- Transmission system separates northwest of Detroit.

4:10 p.m. -- Perry-Ashtabula-Erie line.

Four transmission lines disconnect between Pennsylvania and New York:

4:10 p.m. -- Homer City-Watercure Road, Homer City-Stolle Road, South Ripley Dunkirk and East Towanda-Hillside lines disconnect within four seconds of each other.

4:10 p.m. -- Fostoria Central-Galion line disconnects.

4:10 p.m. -- FirstEnergy's Perry nuclear unit 1 on southern shore of Lake Erie and Avon Lake 9 unit near Cleveland.

4:10 p.m. -- Beaver-Davis Besse line disconnects.

Transmission paths disconnect in northern Ontario and New Jersey, isolating the northeast portion of the Eastern Interconnection:

4:10 p.m. -- Campbell unit 3.

4:10 p.m. -- Keith-Waterman line disconnects.

4:10 p.m. -- Ontario system separates when Wawa-Marathon line disconnects along northern shore of Lake Superior.

4:10 p.m. -- Branchburg-Ramapo line disconnects.

4:10 p.m. -- Over nine seconds, New York-New England transmission lines disconnect. New England (except southwestern Connecticut) and Canada's Maritime provinces -- Nova Scotia, New Brunswick and Prince Edward Island -- separate from New York and remain intact.

Ontario separates from New York west of Niagara Falls and west of St. Lawrence. Southwestern Connecticut separates from New York and blacks out:

4:10 p.m. -- Ontario system west of Niagara Falls and St. Lawrence separates from New York.

4:11 p.m. -- Most of Ontario blacks out.

4:11 p.m. -- Long Mountain-Plum Tree disconnects.

4:11 p.m. -- Remaining transmission lines between Ontario and eastern Michigan separate.

4:13 p.m. -- Cascading sequence essentially complete, with blackout stretching from eastern Michigan and southeast Canada to New York state, New Jersey and parts of New England.

Some time stamps are inaccurate because the computers that record the disconnects either got backlogged or the clocks weren't calibrated properly to the national time standard. Heads will no doubt roll because of this – it makes it harder to pin down the times and the events.

I suspected this from the beginning, but since all plants have backup power for their logging computers (otherwise heads should roll all the way to the top) it is an easy matter to note the time difference after the event and apply a correction to the logged times.

Unless complete idiots began screwing around with the clocks after the event, and before the official inquiry began. Those should be jailed for sabotage and criminal incompetence.
