you didn't give enough info.
1000 people and business plus mine isn't specific.
what kind of people? treehuggers? hippies? or the typical super-wasteful American stereotype?
what kind of business? small things like the mom-n-pop stores? small-town restaurants? or a giant general motors automobile plant? or what about a server farm (which requires lots and lots of power)?
for a mine, again, it depends of what kind of mine. how big is the operation? how updated is its facilities? is it a pit/strip mine? a tunnel mine into the side of a mountain? or a deep mine that goes way into the earth?
then you have the climate. Alaska narrows it down some. its cold there. but you forgot to say how is the town heated. Oil? gas? electric? solar? geo-thermal?
no matter the answer, I can tell you unless the town has tiny mom-n-pop businesses, tree huggers and hippies and an obsolete open pit mine, you'll need a lot more than a diesel generator. you can try something green- like geo thermal, wind, tidal power. if you embrace the power of the future, nuclear power is the way to go. you can have an oil-fired or coal fired plant. it can run on natural gas or methane from composting waste. you can even have one burning trash to make power.
how much kW of power?
if each house had 4 people, then it would be about 250 households. each household would consume about 15 kW a day of electricity.
so for homes you have 15x250 = 3,750 kW
business, say you got small ones and one Costco store.
say 10kW electricity for 12 small businesses and 40kW for the Costco (they have lots of lights and fridges).
so business you have 12x10+40 = 160 kW
say you got the average open strip mine. a small operation that employs 350 people. Its not high-tech. it processes gypsum (different types of mines uses different amounts of electricity) for another plant in nearby Anchorage. That stuff is shipped by rail. I'd estimate 2000kW energy.
homes: 3,750 kW
Stores: 160 kW
mine: 2000 kW
you need to generate at least 5,910 kW a day or you'll have power issues. if all the homes are electric heated and not gas or oil, add another 1000kW a day.
in all, you needs at least 6,910 kW a day, but not more than 9,000 kW. the 2,000 kW a day difference allows some flex and deals with expansion of the town or unexpected high power consumption.
remote Alaskan towns should not rely on diesel, or anything that needs to be shipped in. if the shipment is late or not coming, everyone could freeze to death. You'd want something that comes out of the earth reliably. like geothermal. The earth won't die for a very long time. if you place the plant near a volcano or place with thermal activity, you'll get good, reliable high power output for the next couple thousand years or so.
the rest of the world sees Americans as super wasteful- with excessive packaging, waste of food and resources, low gas economy, naturally it leads to some degree of massive electrical waste. some American families leave TVs on all day and all night. some people forget to turn off their lights. these people are the kind that receives massive electric bills and complain about it. maybe you know some people like that.
treehugger's (people who care about the environment in general) household of 4 people electrical needs: on average 3.5 kW a day.
Average American household of 4 people needs: 14-17 kW a day.
The average wasteful American 4 people family: 32 to 60 kW a day.
see, if you don't know the type of people in the town, it can make a major difference in power consumption.
