Hiya,

I have a question concerning limitation on resources.

I'm trying to model a situation where there's an iron&steel factory that produces 9PJ worth of furnace gas. This gas is converted into electricity in a 350MW power plant. I've introduced other power plants, and an electricity demand.

I've introduced a 'Base Year Reserve' of 9PJ into the resources section, and selected 'Requirements stay unmet' for this particular fuel.

In the energy balance, I find there's 9PJ of this furnace gas is produced, which is as expected. But the electricity production out of this furnace gas is 14PJ, with an unmet requirement of 5PJ.

My question is: is it possible to model the power plant in some kind of way that it uses this 9PJ worth of furnace gas first (because this fuel cannot be imported), after which it switches to natural gas (because this can be imported)?

Thanks in advance,
Gerrit

Hi Gerrit,

Perhaps you could set up an electricity module in which you have two processes, both of which actually represent the same dual fuel plant. One runs on furnace gas and the other on natural gas. You would need to size the processes (ie set their capacity data) so that the plant using furnace gas never used more than 9 PJ of inputs (per year). You can set a merit order for each plant so that the furnace gas is dispatched first and the natural gas used second.

I haven't actually tried this but I think it should work. If you give it a try please let us know how you get on!

PS Not sure how you got a device on the demand-side (a furnace) to produce furnace gas. Normally demand-side devices only consume fuel, not produce it. Can you clarify?

I hope this helps,

Charlie
