[Greenbuilding] Low powered (wattage) water heaters availablethrough Hydro Quebec

[Peter Kidd]

A TOU tariff is only an incentive.  To the extent it is successful, and 
success may just mean fewer distribution system failures, it is a 
benefit to the utility, but it does not actually change a utility's 
liability for a peak that is still possible, when people can sip their 
$4 latte, er, still use "peak" hot water.

Utility controlled load shedding (intentional), turning off customers' 
hot water tanks for example, is an alternative utility strategy.  Many 
of the people on this list are probably already doing things a utility 
might encourage people to do, where the utility shares common interest.
