1. Executive Summary
A new gold mine is proposed at Bird in Hand (BIH) near Woodside in the Adelaide Hills. Power for the
mine will be provided from the state distribution network. A new 11kV connection point will be located on
Pfeiffer Road near the site entrance. Onsite reticulation will be via underground high voltage cables and
ground mount electrical equipment.
Annual site electricity consumption during operation is estimated at 16GWh with a site maximum
demand of 2.8MVA (2.6MW).
The SA Power Networks 11kV overhear line along Pfeiffer Rd will require upgrade from Woodside-
Nairne Rd to just beyond the mine site (approximately 2.4kms). The method of upgrade will involve
either the installation of voltage regulation or restringing of the overhead line conductor pending a more
detailed investigation by SA Power Networks.
Work is currently underway as part of a Power System Options Study to investigate the feasibility of
onsite solar generation and conventional generation to supplement the grid electrical supply.
2. Electricity Grid Connection
The BIH Gold Mine underground and surface facilities will be supplied with a high voltage grid
connection to SA Power Networks (SAPN). Connection to the distribution network will be made at 11kV
with the point of connection located across the road from the site main entrance on Pfeiffer Road. The
Pfeiffer Road 11kV Overhead Line forms part of the Inverbrackie Feeder which originates at the
Woodside Substation located approximately 3.5km from mine site.
It is intended the new grid connection will be completed prior to major construction activities occurring
onsite. The major of construction energy requirements can then be suppled via the grid connection with
minor support via temporary diesel generation where required.
Due to the anticipated mine site electrical demand during operation, the 11kV Overhead Line between
Woodside-Nairne Road and the mine site will require upgrade By SAPN prior to full mining operations
commencing. Discussions regarding upgrade of the 11kV Pfeiffer Road Overhead Line are ongoing with
SA Power Networks, but it is envisaged any required upgrade works would occur parallel with mine site
surface facility construction.
The method of upgrade will involve either the installation of voltage regulation or restringing of the
overhead line conductor pending a more detailed investigation by SA Power Networks.

Augmentation costs must be paid by the project to SA Power Networks to facilitate any current or future
upgrade of the 11kV Overhead Line, Woodside Substation and associated grid infrastructure.
3. Onsite Electricity Supply Infrastructure
High voltage reticulation around the mine site will be via underground conductors and ground mount
high voltage switchgear feeding 11/0.4kV transformers strategically distributed across the site. It is
envisaged the majority of surface loads will be supplied at 400V. Underground loads with be supplied at
either 400V or 1000V via dedicated transformers as required. Further information can be obtained from
the Preliminary Single Line Diagram (17255-SK-002) and the Concept Electrical Equipment Layout Plan
(17255-SK-004). The following provides a brief overview of the main site electrical infrastructure:
1. Underground cabling from the connection point on Pfeiffer Road to the Electrical Metering
Switchboard located near the site main gate.
2. Underground cabling installed nominally along the site roadway from the main gate to the
Wheel Wash and Workshop/Admin Substation. Radial HV/LV underground feeder cables will
supply power to the various surface facilities distributed around the mine site.
3. A high voltage underground feeder cable will supply power from the Workshop/Admin
Substation to the Mining Substation which will be located close to the primary ventilation shaft.
HV/LV cabling from the Mining substation will provide power to the underground mining
operations via the primary ventilation shaft.
4. An emergency back-up diesel generator will be installed close to and connected to the
Workshop/Admin Substation. The generator will provide power to critical site loads in the event
power is not available from the grid.
Typical electrical reticulation equipment to be used will include:
1. High Voltage and Low Voltage Switchgear - including circuit breakers, Load-break switches and
earth switches.
2. Transformers – Converting 11kV to 1kV (for reticulation underground) and 11kV to 400V for
surface facilities.
3. Electrical Protection Relays – To ensure the safety of personnel and to protect electrical
equipment.
4. Soft Starters and Variable Speed Drives – Installed from large motor loads
5. Power Quality equipment – Including Power factor correction units and Harmonic filters (where
required).
6. Emergency Backup Generator – Diesel generator with sound attenuating canopy with a nominal
size of 700kVA.
Some images of outdoor typical electrical equipment can be found in section 10.
Equipment will be nominally grouped as per the provided concept electrical equipment location plan and
the preliminary single line diagram.

All electrical equipment will be procured, designed and constructed in accordance with Electricity Act
1996 (SA), and applicable Australian Standards.
As per Terramin Australia policy, equipment will meet or exceed or statutory compliance requirements,
be of a high quality, and sourced locally wherever possible. The visual impact of all electrical equipment
is to be reduced as far as practical.
4. Electricity Demand
The electricity demand has been estimated over the complete mine life as per the following high level
project timeline:
Figure 1: Mine Development Phases
The preliminary mine maximum demand for the purposes of infrastructure planning has been estimated
at 2.8 MVA during full operation. The mine is estimated to have an average real power load during the 5
year operational phase of between 1.8 and 2.6 MW.
Major loads include:
1. Mine Ventilation Systems
2. Underground and above ground pumps
3. Underground drilling machinery
The site maximum demand has been calculated conservatively as final duty and operation of equipment
is not yet known. Table 1 below provides an overview of estimated site connected and actual loads
during the 5 year mine operation period.

Printed: 06-Oct-2017 at 8:48
For the purpose of calculating annual electricity consumption a nominal load utilization factor of 0.7 has
been applied. Based on the maximum demand and the load utilization factor, annual consumption
during operation is estimated at 16GWh.
During the construction of the surface facilities prior to mining operations, the required energy demand
will be significantly lower. The construction phase energy consumption is estimated at 0.82GWh per
annum. This figure is based on the office, admin, workshop, security and amenities loads operating for
12 hours a day and 6 days a week.
When underground development commences, but prior to full ore production load will begin to ramp up
as additional mining, ventilation and pumping equipment is installed. The extra loads will require
~700kW of additional supply beyond that required for surface construction. This equates to an annual
consumption of
It is estimated that during the one year mine closure period once ore production has ceased power
consumption will be 1.1MW.
The following table summarizes estimated energy demand across the mine lifecycle:

Based on the estimated annual electricity consumption (table 2) and the 2016 National Greenhouse
Accounts Factors (Section 2.3 - Indirect Emissions from Electricity) green house gas emissions per year
are calculated as per the following table.

Printed: 06-Oct-2017 at 8:48
The total estimated green house gas emissions over the complete mine life is 49,660 tons of CO2-e.
6. Alternate Sources of Electricity
Work is currently underway as part of a Power System Options Study to investigate the feasibility of
onsite solar generation and conventional generation as supplementary sources of electricity.
The Admin and Workshop Buildings will have significant roof space available for installation of a solar
system. The proposed solar system would be used to reduce green house gas emissions and offset
demand from the electricity grid. Based on an estimate of half the roof space (~440m2) suitable for
installation of solar panels, a system of approximately 60kW could be installed. Further opportunities to
install additional solar capacity will exist in the event more of the workshop and Admin building roof can
be utilized or additional structures are required onsite.
In addition to onsite solar generation, options for the site Backup Generator to operate as a Non-export
Embedded Generator are being investigated. The fuel source for the generator is to be determined by
the Options Study, but would be either diesel or gas. The generator would operate during periods of
high mine site demand in parallel with the electricity grid. This scheme would provide load side demand
management to reduce mine site reliance on the local grid and the Woodside Substation.
Final feasibility of alternate power sources will depend on negotiation of the connection to the 11kV
Pfeiffer Road Overhead Line, and outcomes of the Power Supply Options Study.
7. Energy Efficiency and Power Quality
Endeavors to increase energy efficiency will be included in the mine site electrical design.
Some of these measures to be considered as part of electrical design include:
1. Installation of high efficiency equipment including motors and transformers. All equipment to
meet Minimum Energy Performance Standards (MEPS).
2. Utilization of variable speed drives to optimize energy use of electric motors where practicable.
3. Cable sizing for energy efficiency as well as current carrying capacity.
4. Site power factor correction equipment to minimize reactive power losses throughout the
reticulation network.
5. Harmonic filtering to minimize the effect of harmonics on the site power network.
In additional to electrical efficiency, power quality and associated impacts on the local grid will be
considered by the electrical design. The site will comply with power quality limits set by SA Power
Networks as outlined in their Service and Installation Rules and the grid connection agreement. Any
impact the mine site will have on grid power quality must have negligible impacts on other SAPN
customers. The electrical design will identify any potential non-compliance and make recommendations
regarding required mitigation measures.

8. Mine Closure
Once mining operations are complete, the majority of mine electrical infrastructure is to be removed.
Any upgrade of the regulated SAPN network will remain in place for the future benefit of the local
community. Discussions regarding use of the site by the local community beyond mining are to be
undertaken prior to removal of all electrical equipment. If required, the grid connection can be retained
and used by any new operators of the remediated mining site for the supply of electricity.

Efficiency is only used to calculate electrical input power when motor (shaft power) ratings are given in kW. When the FLC is specified instead, this value is ignored.
The sum of the connected loads takes into account power factor but not load factor.
For the columns: "Power Factor" and "Load Factor", if these load characteristics are not known, the user may write "default". By writing "default" into this cell, a typical valueThe user is only required to enter data into the white (non-shaded) cells. Refer to the legend adjacent for an explanation of the cell data.
Load Factor is the factor to which the load is designed to operate at. Eg. An electric motor may have a FLC of 10A, but the load only causes the motor to draw 7.5A, therefore 0.75 Load Factor. Load Factor can be
determined from the mechanical design or from actual measured data.
The Diversity Factors listed in the "Diversity Factor" column header are suggested. These values may be manipulated by the user to suit the specific installation.
