• Sensitive load broken into 2 categories
• Public health and safety
• PROPS Priority (1-3)
• Hospitals, water and sewage
pumping, fuel delivery systems
etc.
• Will not be allocated to an AUFLS
block
• Highly Sensitive Load

other categories (food production)
• Standard VoLL value applied
• Possible to allocate to an AUFLS
block
• User submitted VoLL
• Customers over 25GWh per year
• Customer class percentages must sum to
100%
BREAKOUT: INFORMATION
PROVISION
Introductions
• In small groups
• Identify any strengths/weaknesses of the
straw man proposal
– Write each on post-it note (one per note)
• Report back to group
– Discuss how each would impact on your organisation
– POLL: Are you likely to submit user submitted VoLL for your
demand units?
SLIDE 16
DISCUSSION: INFORMATION
PROVISION
Introductions
• As a large group
• Were there any specific challenges to meeting
the 60% compliance requirement?
– White board session
• Poll: Will the proposed straw man alleviate the
challenges?
– Follow up: If no, what issue remains?

How many (estimate)?
– How much time is required to prepare information?
• If the information was provided twice a year would it be onerous?
• Identify size of the impact (# effected/time/resources)
• POLL: Are the profile information requirements practical?
