Availability factor values

[Gary]

Hello,

I'm new to TIMES and have a basic question. I'm interested in US energy sector modeling, particularly electricity produced by coal-fired power plants. 
My question is how to provide specific availability factor values for coal-fired power plants for the forecast period? I mean, I want the solver to consider a specific availability factor value for each year, that I provide. I downloaded the 12 demo files and was working on them. In demo 8's B-Y templates, I changed the AFA under ELCCOA which I think represents power plants using coal as fuel. But I think this applies only to base year. Please help me in this regard.

Thanks for your assistance. 

Regards,
Chandra
