- Using the $0.05/kwh quoted rate, a 1000 MWE plant produces $50,000 worth
- of electricity an hour. At the retail rate around here (0.114/kwh in
- the summer) that works out to $114,00 per hour or $1900 per minute
- or about a buck a revolution on the turbine (1800 rpm typ). When
- the plant is not operating, not only is the utility not earning that
- revenue, it is buying the electricity from elsewhere. Or assuming
- the utility base loads its least cost capacity, generating it from
- more expensive sources.

- Someone saying that availability does not seriously affect costs is
- about like a person who has never seen a gun picking the thing up
- and peering down the barrel while pulling the trigger. In other words,
- somewhat uninformed.
