Utilities sector

[Roadmap2Retire]

My only exposure to utilities was via an ETF, which I ended up selling yesterday. Looking to initiate a position in one or more of the following stocks instead of using an ETF.

• Diversified Utilities
  - Algonquin Power & Utilities Corp (AQN.TO)
  - Atco Ltd (ACO.X.TO) / Canadian Utilities (CU.TO)
  - Brookfield Infrastructure Partners LP (BIP.UN.TO) (BIP)
  - Brookfield Renewable Energy Partners LP (BEP.UN.TO)
  - Duke Energy Corp (DUK)
  
• Electric Utilities
  - Consolidated Edison Inc (ED)
  - Fortis Inc (FTS.TO)
  - The Southern Company (SO)
  
• Water Utilities
  - American Water Works (AWK)
  - Aqua America (WTR)
  
• Gas Utilities
  - ONEOK Inc (OKE)
  

Any other recommendations for companies I should be looking at?
