there will always be new comers trying to buy 100 000 power at 0.18 each
If I need 100k of power (I use about 35mil per day) I will buy 100k of power from the market. I've been very busy lately but every now and then I walk past my computer and login to keep up with my finished expansion. I don't have time to chase 100k of power even if it's 18 caps a piece.
Call me a new comer if you like but I will never have enough power because I am still expanding. I only have 9 PoWeR StAtIoNs

so when I finish expanding (in a year or 2) I will still need power. Maybe by then I will have found someone who can send me a nice, big, fat and juicy contract for 100 mil of power per day, maybe this won't be enough.
Power is the least of my problems. It's still cheap compared to other products. Now wood is an interesting market. Nobody really knows what is a good price. There are a lot of small amounts on the market and Q0 wood is priced way over Q1-Q3. Still it is cheap compared to steel(NPC). We don't need that much of it compared to stone and steel.
I'm buying as much wood Q0-Q3 as I can while the market price is under the NPC price for wood. If someone starts selling higher Q cheaper I will expand with higher Q wood.
