Hi everyone,

I have different results when it comes to using running cost and also optimization (osemosys). I didn't include any external cost/emission cap and all other costs assumption remain the same.

The running cost dispatches and build the cheapest plant and i think osemosys also do the same but why did it show different result? I observe that osemosys's capacity mix are more diversified than using the running cost feature.

Any feedback is most welcome.

Thank you

Hi Mohd,

Actually, the RunningCost dispatch rule does not instruct LEAP to construct new capacity - it is used for process dispatch only. Capacity expansion is handled by the processes which you enter in the Endogenous Capacity variable:

With OSeMOSYS, you can allow LEAP to conduct a module-wide least-cost optimization for both process dispatch *and* capacity expansion, finding the lowest net present value of all future capacity and running costs for the transformation module.

Hope this helps,
Taylor
