Energex Integrating Batteries a Network Perspective Thursday 26 November 2015
2015
2020
2030
Network of the future • Home automation
• electric vehicles/batteries
• renewable generation
Connected network • Complex power sources and flows
Traditional network • Centralised
• Emergence of two-way power
flows
Direction is clear
Energex is establishing clear deliverables for
the period 2015 to 2020 to underpin a long term
sustainable business and enable customer
choice for their energy needs
~1000MW on installed domestic PV capacity
in a ~5000MW network. In some postcodes
>60% of customers have PV. Total energy
delivered is ~ 7% (1464GWh) of total
Energex has high Levels of Domestic PV
Where were you on 8th August 2015 ?
Minimum Load was 1663 MW @ 12:30 pm
Response to the Challenge
Normal Load Control
Program
‘Solar Sponge’ Load
Control Program
24 MWh of energy moved
to fill in the trough – from the use of hot water system loads
Being used during the period of solar production
Energex continues its transition to a smart grid
Drivers for battery pilots and trials
o Support customer energy needs
o Promote connected services
o Reduce network impacts due to PV
(e.g voltage rise and unbalance)
o Enable higher penetration of PV

How does Energex
reduce costs or
generate revenue in a
market where our LV
network has a high
penetration of batteries?
Battery pilots
Market driven battery storage pilot
• Target sections of the network that would be likely to benefit from the
installation of batteries
• Run in cooperation with businesses selling batteries
• Offer incentives to customers who install batteries and provide
Energex with monitoring and control
• Metering installed to enable cost reflective pricing (TOU tariff, or TOU
demand tariff when available)
• Metering will also enable collection of engineering and power quality
data
Targeted areas of the network
Monitoring and control
• Incentives will only be paid to customers who install batteries and
provide control and monitoring
• Customer control system that prioritises solar charging and peak
discharging
• Controlled by an Energex approved interface:
AFLC DRED
Control system integrated with Poweron DMS
• Metering that provides engineering and power quality data into Energex’s
Distribution Monitoring Analytics (DMA) platform
Run in cooperation with businesses
selling batteries
Promotion of the incentive will be via businesses selling batteries
to customers, with the incentive paid directly to customers
following installation of the battery. The trial areas, conditions and
incentive value will be published on the Energex website.
10 kWh < $10K 19.2 kWh < $20K
What is out there now in
SEQ?
• 3 - 20 kWh systems
• $5K to $20K
• Shift to Lithium Iron but
still lead acid, flow and
gel systems
• Over 20 vendors
• Disparate array of
control systems
