    Hi, MrGriff 

    Please check the below picture and the formula for creating a new column.

     

     

    Power Used CC =
    VAR currentname = 'Table'[Name]
    VAR currentpower = 'Table'[Power]
    VAR nextpower =
    CALCULATE (
    MIN ( 'Table'[Power] ),
    FILTER ( 'Table', 'Table'[Name] = currentname && 'Table'[Power] > currentpower )
    )
    RETURN
    IF ( NOT ISBLANK ( nextpower ), nextpower - currentpower )

Sorry to re-open this again but I have seen that the calculation is wrong, If the current and next power are the calculation just looks a the next value that is higher in value... but really I if the value is the same the result should be 0..

 

If you can help that would be great
