South Carolina Electric & Gas (SCE&G) and Berkeley Electric Coop collectively serve areas East of the Cooper (Daniel Island, Mt Pleasant, Awendaw, Isle of Palms, Sullivans Island). I have used either or both in homes I have lived in over the past several years, and recommend either. At present I have SCE&G for my natural gas and Berkeley for my electric. I'm in Carolina Park. My view, looks like Berkeley Electric is a bit less costly, but the cost differences are not that dramatic. Most folks would probably tell you, and my personal experience is, that SCE&G delivered a bit more consistent electric power with a few less outages. Could just have been my experiences based on the specific neighborhoods. Again, not a major issue either way. I would not rule out living in any area of the Greater Charleston Tri-County based on the electric supplier. There are going to be several other more basic factors of greater import, such as location/relationship to work or play, price range, school system prioities, those sorts of things.
