Cogeneration for Dummies

Hi, Antti,
as you said, the CHP I am trying to model is a CCGN+HRGS. The installed capacity is only electrical capacity, so when I model it as backpressure, the model (naturally) invests in new capacity. The HRGS is 210 MW, how do I add that capacity to the electrical (120 MW)?
As I said, my data is not complete because it's confidential. But I am hoping the CHP generates 625 tonnes/hour of steam for the alumina refinery. To convert the thermal capacity I was using=
 tonnes/hr steam approximate heat value is 2000kJ/kg,
1tonne steam / hr = (1000kg/t)/(3600sec/hr)x(2000kJ/kg) = 555kW
But, if i'm not wrong, the CHP only gets to generate 378 tonnes/hour of steam with those conversion factors. So I may be miscalculating something (very possible, as I'm not an engineer).
Thanks,
Sara
