Does a 16"W x 13" deep counter space need an electrical outlet?
210.52(C)(3) Peninsular Counter Spaces. At least one receptacle outlet shall be
  installed at each peninsular counter space with a long dimension of 600 mm (24 in.) or greater and a short dimension of 300 mm (12in.) or greater.


So yes according to the NEC you do need an outlet.  But it is really really close to not meeting the specifications, meaning it might be easier calling your inspector than it is debating with us.
