I get my power from Western Power Distribution and experience the
occasional 'blip' and power outage (it's not just my property either,
others in the area suffer at the same time). On looking at Western
Powers' web site I see no logs, so am curious if their is any onus on
the distributor to make any failures available to their customers,
online or otherwise?

How often have you been off, and for how long ?

Are you aiming towards getting a payment for the loss of supply per the
guaranteed standards of service ?

AFAIK at present, the customer themselves have to claim, giving dates
and times, although this flies in the face of the automatic payments
that are supposed to trigger for other failures due under the standards.
