Hello !
I am looking for (low speed) power line modems that can be
used to transmit / receive data between transformer
substations and homes using the 230 VAC underground power cables.

Requirements are approximately:

Moderate data rate (say 1200 to 9600 baud).
Operating range up to 500 meters.
Carrier frequency probably around 100 kHz.
Confirm to European standards regarding RF emission, etc.

Any ideas?

Best regards

Agust, you might want to try a company called DataLinc located in Redmond,
Washington. They have a WEB site at http://www.data-linc.com and have modems
that do what you are asking for.

Good luck!
