After I saw this on James Hamilton's blog the other day I did a quick check of BD-R versus 4TB HDDs cost per GB. Using whatever I could find after about 5 minutes of looking around, I came up with $0.05/GB for both types of media. If anyone can provide a link to BD media for sale at a price that make this economical I'd be interested to know.

The saving is in power consumption for cold storage.

  Exactly. This is low power consumption for infrequently accessed data.

  Are modern hard drives not rated to survive very long in spun-down, powered-down condition?

I would think the media's longevity factors into the lifetime cost. If the optical media is certified for 50+ years, that essentially means they won't have a need to recopy data if for some reason they want to preserve it.. for a long time.. I don't know how long magnetic tape lasts, but I would imagine it would be a huge pain to need to keep backing up old tapes to new tapes every X years.
