I'm including electricity from diesel generators within my demand tree. Outside of LEAP, I've calculated the required litres of diesel as follows:

Total GWh / (kwh per litre of diesel * generator efficiency)

However, LEAP appears to be assuming that 100% of the diesel is being converted, providing output GWh of twice the expected value.

I'm sure that I'm not approaching this the right way, could you please advise if there is another way to model diesel generators?

Cheers,

Matt

Sorry for the delay in responding. I am not completely certain of how you are modeling the diesel generator, but if you could provide more detail such as the type of demand technology branch you are using to represent the generator (total energy vs. energy intensity) and the expressions you are inputting into the branch variables, that would be helpful in determining the issue.

If you are modeling the diesel generator on the demand side, you can't really show the conversion from one fuel to another (i.e. from diesel to electricity) so if you are interested in fuel costs and fuel imports, it may be better to model it as a transformation module. If you want to keep this process separate from the electricity generation module, I suggest creating a new transformation module, and moving this module on top of the other modules using the blue up arrow above the tree. LEAP transformation calculations start from top of the tree to the bottom, so ordering the modules in this manner means that electricity demands will first be met by the diesel generator, and any remaining electricity requirements will be passed down to the electricity generation module or imports.

In terms of module properties, I suggest including capacity data, at a minimum. If you are only modeling one unit, use the PercentShare dispatch rule, and ensure the Process Share is set to 100%.

Hope this helps! If you have any questions, please let me know.

Thanks,

Much appreciated,
