This short video provides background for the hydroelectric generator, wind generator, and Bicycle Generator videos.
The electricity distribution grid in New Zealand is run by a state-owned company called Transpower. Their web page can provide a lot of information for keen students, and electricity transmission grids here and elsewhere are based on a lot of good physics. The Cook Strait cable for example has a lot of interesting physics behind it.
