How to convert cable thermal losses [Watts] into enthalpy?

Hello fellow engineers

I have a certain thermal loss from my power cables, it's about 15Watts loss, and I somehow have to convert that into a enthalpy so I can calculate how much more my cooling unit has to work.

The cable is a 4G4 powerflex copper cable. 

the ambient temperature of the room is 40 degrees celcius.

What do I do?

    1 kwhr = 860 kcals 

    15 watts adds 13 kcals of heat in an hour. That much extra has to be removed by the cooling system.
