Hi,

LEAP is giving me outputs for total electricity production that should not be possible with my input data. Between the base year and the first simulation year the theoretical maximum output from the technology increases by 30% but the calculated output increases by 1300%. It reduces to 700% if I alter the dispatch rules but such a high value still should not be possible.

Does anybody have any idea why this might be?

Thanks,
Tom

Hi Thomas,

You'll need to be more specific. LEAP dispatches electricity to meet the requirements that are placed on the electricity generation module, so my first question would be to ask what your electricity demand is, in both the base year and first scenario year. If demand increases significantly, then generation may also increase significantly, if there is sufficient available capacity.

Good luck,

Taylor

Thanks for the rapid reply!

The overall demand remains more or less flat, decreasing slightly between the base year and first scenario year. I have 13 different processes contributing to meet the demand. The problem is specifically with the Solar option. In the base year it is producing at maximum capacity (given the average capacity factor etc.) - the historical production matches the other relevant inputs. In the first scenario year it suddenly produces 13 times more, but the capacity has only slightly increased. If I calculate the theoretical maximum by hand it is only just more than in the base year. Is it possible that additional Solar capacity is being "imported"?

Hi Thomas,

No, solar capacity is not something that is specifically imported in LEAP.

What is the First Scenario Year for your solar process set to? Remember that before the first scenario year, generation is controlled by the Historical Production tab, but after, LEAP uses the Dispatch Rule variable to determine how much energy will be produced. You can read about dispatch rules here:

Hope this helps,
