There are many ways to enrich Uranium to the 3% to 5% typically used in power plant reactors and gas centrifuges are one of the most efficient and economical way to do this at this time. The real issue is not if they need them, but if they are stopping at that level of enrichment or are their plants designed instead to go all the way to weapons grade enrichment levels: e.g. 80% to 95%.

Because the power plant is the source of electricity
An electrical power plant was built just outside the city.
It is legal to build a nuclear power plant in the U. S., provided the licenses and permits are granted.
Centrifuges are used for enriching ura nium in the U-235 isotope. They work with gaseous uranium hexafluoride, if you have a long line of hundreds of centrifuges and pass the gas through them, you can gradually spin off some of the heavier U-238 resulting in a main stream with a greater percentage of U-235. This method has been used in Europe for many years and uses much less power than the older gaseous diffusion method which has been continued in the US, but I think that is now changing to centrifuges. This is what the State Dept is so concerned about happening in Iran. If you have enough centrifuges you can get nearly pure U-235 out which of course can be used in weapons.

A power plant generator
The average cost of building a hydro power plant on the Columbia river is 559,220,000.
electrical power from the power plant to consumer goes through the transmission & distribution system, first we transmit the high voltage power from the power plant to sub station in sub station we step down the voltage according to need & distribute it to the demand.
Coal Power plants are cheaper to build.
