Policy review and driver of peak demand
Network planning and DSP
Network regulation and DSP
Network pricing and metering
Introduction
Period of major policy review
how the market can
better support efficient demand-side participation (DSP):
• Australian Energy Markets Commission (AEMC) - Power of
Choice review of DSP
• Productivity Commission review network regulation frameworks
• The Senate Inquiry into electricity prices
• Commonwealth Government Energy White Paper
Key policy goals:
• Improved incentives for distributors to engage in DSP
• Efficient price signals - cost reflective/time varying network
tariffs
• Rolling out interval meters
The peak demand context

The peak demand context (cont.)
Regulatory role
Managing peak demand
(oversight, allowances,
incentives for
regulated firms):
Network solution
Build more demand
driven capital
infrastructure
Demand-side
Use distributed
generation to
negate need for
more network
infrastructure
Reduce/alter
timing &
magnitude of
consumption
• encourage efficient
combination of
investments
(network & demandside)
• encourage efficient
pricing structures
Long term & significant network planning
Nationally consistent regulatory requirements to
encourage consistency, transparency and efficiency
in network planning outcomes:
• Regulatory investment test for distribution
(RIT-D)
• Annual planning review and reports (including
detailed forecasts of demand/capacity)
• Demand-side engagement strategy (for
considering non-network options and engaging with
non-network providers
Long term & significant network planning (cont.)
RIT-D &
non-network
options
Identify need & if project
eligible for RIT-D
Screen for potentially
credible non-network
options
Final project
assessment report
Consultation
If credible non-network
options exist – publish
non-network options
report.

Regulatory determinations
NER requirement for distributors in proposing
forecast expenditures:
• Demonstrate consideration and provisioning of
efficient non-network alternatives
AER classification of distributor services:
Direct control
Negotiated
Unclassified
Regulated monopoly
services
Potentially contestable or
customer specific services
Unregulated
competitive services
?
?
Demand-side services
?
Regulatory determinations (cont.)
Funding demand-side investments by distributors:
1. Regulatory allowances for operating (opex) and
capital expenditure (capex)
2. Retainment of capex savings from successful
demand-side projects:
– Possible reforms to savings retainment period
3. Demand management incentive scheme:
– Possible reforms to design and power of scheme,
allowing capture of broader market benefits
Regulatory determinations (cont.)
Form of control during regulatory period:
• Cap on maximum recoverable revenues
• Cap on maximum price chargeable

Other (solar, energy
efficiency schemes, carbon)

Consumer retail
electricity bill
Data Source:
AEMC, Nov 2011.
Majority of residential network tariffs are flat and don’t vary by time
no signal of peak costs
Efficient, cost reflective / time-varying network tariffs = DSP
reductions in peak usage are reflected in bills
Network pricing
Key proposed reform
Gradual introduction of
cost-reflective, time varying network tariffs
• Segment consumers into size categories:
• Mandate such tariffs for large residential/small business
• Medium-large consumers transitioned to such tariffs but
allowed to opt-out
• Small consumers maintain flat tariff but allowed to opt-in
Accompanying reforms:
• Reform/tighten pricing principles in NER
• Improved consultation procedures – distributors with
retailers and consumers
Technological enablers - Metering
• Interval meters
enable efficient price signals
• Interval meters with additional communication / smart
features
energy management possibilities for
consumers
• Key proposed reform
phased roll out of interval
meters with defined standard technology specifications
• Require for all large consumers
• Require for all new meter connections,
refurbishments/replacements
• Roll out model
Contestable
Concluding comments
• Significant phase of regulatory and market
evolution re how networks engage in/with DSP:
