Historically, every 4 quarters SO has increased dividends about $0.18 per share. According to this pattern, they should increasing to $0.491 this year. their annual pattern in the past few years has been $0.42 to 0.438 to 0.455 to 0.473.
Their new Coal Gassification plant in Kemper County, Mississippi is being financed with approved ADVANCE utility price increases so this capital expenditure should allow them to increase dividends again (my opinion)
Like any intel, it's never all in one place (and you wouldn't want it to be to keep from being tainted or biased and subject to manipulation). Also intel is like fishing.....no telling how often, how big the catch will be or its quality. Just make the best of what you can pick up. Being in SO's service area (Atlanta) I hear a good bit about rate changes and issues re: new nukes and conversion to/building gas fired plants. Right now my sense is that SO is a good place to be.
