Rare is the day I'll sell an electric power generation play. I'm reiterating my Buy rating for Northeast Utilities (NYSE: NU), first recommended on May 6, 2009 at a price of $21.48.

NU's business model is low-risk -- its electric unit primarily serves customers (1.9 million in all) in land-of-steady-habits Connecticut, Western Massachusetts, and New Hampshire, and offers above-average total return, with only a modest downside risk. In this investing environment, that's impressive.

Readers of this space know that one of the preferred sectors is the electric power generation sector.

And the sector is favored for a reason that may not be obvious to all. Electricity via wind, solar, and nuclear generation is likely to play a large role in energy as climate change reduction, then elimination, becomes a societal goal. Electricity also remains a potential propulsion source for cars, particularly once oil resumes its inevitable climb. And with the above in mind, electric power generator Northeast Utilities (NYSE: NU) is worth a review.
