Placable BGAs

Post by bossmanslim »

I did the math on these and it seems like they will take about 100 years to pay back due to low through put. They appear to be a roughly a
2x multiplier on the inputs. The small BGA uses 2400 units of cut beets per month, producing an extra $354 meaning it will take 102 years to pay off the $435k the plant costs. If all production lines can be run in parallel at max production, that would take 25 years not counting production costs.

Anyone used these, they seem like a waste of money currently? I'd like to see some opinions before I edit the xml. I'd probably do a 10x increase on inputs, outputs and storage while doubling the cycles, which should put it at a 5 years payback. Other production chains payback in about 1 year if they can be kept fed.

Seems like Giants missed some zeroes when adjusting the BGA numbers.

Consider it an investment in your great grandchildren's future.
Or, edit the XML like you said *thumbsup*

They are much more efficient when feeding them Silage. I paid off my £840k BGA plant in under 2 years. Kept it fed and make sure it runs 24/7, I did this by dumping silage bales infront for the hopper so it constantly fills.

I assume this is the medium plant, 250kw. All numbers are from the xml file

Payoff = cost /(products revenue - silage revenue if sold)

Cost is 875000
Silage revenue is 0.171 per liter
Product revenue is 0.35 per liter of electricity, 0.45 per liter of methane, 0.033 per liter of digestate
1 cycle of is 2120 silage = 1909 electricity, 1 methane, 636 digestate
24 cycles per month
12 months per year

Hard = 94196 profit = 12*24*((1909*0.35+1*0.45+636*0.033)-2120*0.171)
Normal = 169552 (1.8x multiplier for normal)
Easy = 282587 (3x multiplier)

Payback

Hard = 9.3 years
Normal = 5.2 years
Easy = 3.1 years

The only way to get a less than 2 year payback in the base game is to not consider the cost of the silage fed into the system and to be playing on easy.

I did some trials with the smaller Biogas plants, their capacities are so small it seemed to me to not be worth the trouble. One small grass field would fill the medium to capacity and keep it busy for longer than it takes the grass to regrow.
