My GC says we can just put them in the wooden trim between the windows. Hasn't happened yet, so no pictures or confirmation that this will work.

What is the total width of your bank of windows?

Within 24" of the sink or at least 24" from the sink? Edge of sink or center of sink? Makes a difference.

I would not want an outlet that close to my sink, but then general electrical code requires receptacles no more than 12 feet apart on wall runs.

Within 24" of the edge of the sink.

National Electrical Code

This is throwing is a curveball too I wanted all under cab plug old and go outlets in backsplash I have a very wide window above kitchen sink and the uppers are more than 24" from edge of sink. Not sure what we are going to do. Perhaps I should have gone w a very large sink. Will be following the answers you get

There are pop up outlets that can go in the countertop My hubby didn't want these in the marble, so he vetoed that potential solution

Huango, thanks for the picture! That's what I was trying to describe.

The way I read the code, this only applies to countertops on islands or peninsulas.

What only applies to islands??

(1) Wall Countertop Spaces. A receptacle outlet shall be installed at each wall countertop space that is 300 mm (12 in.) or wider. Receptacle outlets shall be installed so that no point along the wall line is more than 600 mm (24 in.) measured horizontally from a receptacle outlet in that space.

Exception: Receptacle outlets shall not be required on a wall directly behind a range, counter-mounted cooking unit, or sink in the installation described in Figure 210.52(C)(1)

Most pop up receptacles will not meet code for the required receptacle for several reasons. Most are only listed for temporary use. The only one I have found that is listed for such use is not in production the last I heard.

In any case, ANY receptacle device installed IN countertops MUST be "LISTED for the application" That means that an independent government approved testing laboratory has tested the device to ensure certain standards have been met for outlets designed to go IN countertops, and that the installation instructions show the proper requirements for installing it in the countertop to meet the standards. This includes that the device's 'faceplate' seals well enough when closed to keep water out of the junction box, not a characteristic that a "wall" receptacle would normally poses.

210.52(C)

(5) Receptacle Outlet Location.

Receptacle outlets shall be located ON or ABOVE, but not more than 500 mm (20 in.) above, the countertop. Receptacle outlet assemblies LISTED for the application shall be permitted to be installed IN countertops. Receptacle outlets rendered not readily accessible by appliances fastened in place, appliance garages, sinks, or rangetops as covered in 210.52(C)(1), Exception, or appliances occupying dedicated space shall not be considered as these required outlets.

Informational Note: See 406.5(E) for requirements for installation of receptacles in countertops.

406.5

(E) Receptacles in Countertops and Similar Work Surfaces in Dwelling Units. Receptacles shall not be installed in a face-up position in countertops or similar work surfaces.

Thank you for all of the feedback. My contractor is a bit nervous about coordinating a counter height window I think. I had clipped this picture a while back and like this as an option too. I'm not sure whose kitchen it is, so sorry for not giving a shout out. It's really nice though.

Yes, my contractor got the height wrong. Contractor had to hand-dig out about 0.5 inch out of the wooden sills, so that my marble sills can sit on top.

So I chose to put in matching marble window sills, to make up for that 1" delta. But it made marble countertop templating easier (the whole thing was difficult enough - should see my post about my marble 1-piece backsplash install: ugh).

And I love my marble sills.

See my thread about my ordeal:
