power vs. supply

Taking a test, I had to choose from "supply" and "power" to end the followin sentence: The farmhouse was so isolated that they had to generate their own electricity supply / power. My option was supply and it turned out to be the correct one, but I only choosed it becaused it sounded OK to me and not because I have a basic knouledge when to use these words. Could you explain to me why "supply" is the correct answer and not "power" ?

Good question. It is simply that we use the noun ('electricity') with 'supply', but not with 'power', where we use the adjective ('electric'). Hence, these are accepted: electric power electricity supply I am not sure that a general rule can be extrapolated, but you can probably notice that we use 'supply of electricity' but not 'power of electricity'.
