The installation shifted about 2m within the base of the 180m high earth and rock fill gravity dam wall of the 3,906GL reservoir. After initial consternation regarding the integrity of the wall (declared safe after lengthy assessment), the hydro installation was repaired/replaced but was off-line for several years.
Toronto during the Northeast blackout of 2003, which required black-starting of generating stations.. A black start is the process of restoring an electric power station, a part of an electric grid or an industrial plant, to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.
4:12:03 p.m. Windsor, Ontario, and surrounding areas drop off the grid. 4:12:58 p.m. Northern New Jersey separates its power-grids from New York and the Philadelphia area, causing a cascade of failing secondary generator plants along the New Jersey coast and throughout the inland regions west.

[3] Reactor 2 was already shut down for refueling at the time of the incident.
The sudden release sent a 20-foot (6 m) crest of water northwest of the reservoir about 1.75 mi (3 km) down the ridge to the East Fork of the Black River inside the north upstream side of Johnson's Shut-Ins State Park. The river at the park is normally very shallow with rapids running over granite boulders.
As an example, consider the use of a 10 hp, 1760 r/min, 440 V, three-phase induction motor (a.k.a. induction electrical machine in an asynchronous generator regime) as asynchronous generator. The full-load current of the motor is 10 A and the full-load power factor is 0.8.
The A. B. Brown Station ash management impoundment was formed by building a dam to block off the outlet of a natural ravine about 0.5 miles (0.8 km) from the Ohio river. The ash pond consists of two dams. The Lower dam (built in 1978) has been classified by the Indiana DNR as a Significant Hazard (State ID#65-7, permit #D-4405, rev 1). The ...
