How do I show a card value based off a slicer from a different table?

[Anonymous]

In the attached image, the visual I am having trouble with is the card at the bottom.
This card is meant to show the month with the highest energy consumption. I have disabled the month slicer's (at the top) interaction with the card. The only thing affecting the card should be the year slicer (at the top left). So for 2020, It should show January instead of April. 

The Month data is from the energy_consumption table, and the year slicer is from the contracted_capacity table. 

Any suggestions? Thanks

Hi @Anonymous 

You can create a measure, and put the measure to the card

Measure = var a=ADDCOLUMNS(ALL(energy_consumption),"month",energy_consumption[Date].[Month])
var b=SUMMARIZE(a,[Year],[month],"sum",SUM(energy_consumption[energy_consumption]))
var c=MAXX(FILTER(b,[Year] in VALUES(contracted_capacity[Year])),[sum])
return MAXX(FILTER(b,[Year] in VALUES(contracted_capacity[Year])&&[sum]=c),[month])

Output
