I would check math and make sure it's 1 cent/KWH as that is very very cheap. Make sure all taxes/fees are included in it. But if you have 1 cent/KWH you should be able to mine with even a S7 for quite a long time. You would not need the newest efficiency miner at that price.
But again make sure your math is correct. Also check how much electricity you have as not sure if very limited amount. But if you have a decent amount of electricity at that price, and can handle heat/sound you have a very good investment opportunity obviously.
I would reiterate this again, Check your math!! Check your Math!! Check Your Math!!
If you really have .01 electricity you could mine with anything 1 generation old, IE S7, and make a profit.
The single largest cost for mining is electricity, after all mining is turning electricity into hashes, and you have close to the best cost possible.
But beware there is a lot to learn (Wallet, miner hardware, mining software, settings, pools, etc)
Start slow and make sure you have the basics down to you can make the most coin possible before you go all in.
I also agree the S9's are still a little expensive, an S7 will cost a lot less and give you something to work with.
As another thought, you may also want to look at alt coin mining. With .01 electricity and a good GPU rig there is also profit to be had.
