Tom,
I believe the 24" rule applies to "wall countertop space" and not the peninsula you show in your drawing. Since you have more than 12" behind your sink, I believe your peninsula countertop should be considered one space and would satisfy code with one receptacle in the end cabinet. I would run it by your Code Enforcement Officer though.

E3901.4.3 Peninsular Countertop Space

E3901.4.4 Separate Spaces
Countertop spaces separated by range tops, refrigerators, or sinks shall be considered as separate countertop spaces in applying the requirements of Sections E3901.4.1, E3901.4.2 and E3901.4.3. Where a range, counter-mounted cooking unit, or sink is installed in an island or peninsular countertop and the depth of the countertop behind the range, counter-mounted cooking unit, or sink is less than 12 inches (305 mm), the range, counter-mounted cooking unit, or sink has divided the countertop space into two separate countertop spaces as defined in Section E3901.4.4. Each separate countertop space shall comply with the applicable requirements of this section. [210.52©(4)]
