Building and maintaining Jemena’s electricity assets
Jemena owns and operates one of five licensed electricity distribution networks in Victoria, covering more than
950 square kilometres of north-west greater Melbourne. The network footprint incorporates a mix of major
industrial areas, residential growth areas, established inner suburbs and Melbourne International Airport.
Inspection and maintenance activities are crucial to ensuring the long-term safety, reliability and efficiency of
Jemena’s electricity network.
The Jemena Electricity Services Agreement (JESA) contract commenced in December 2018 and outlines the services
required from Zinfra to build and maintain Jemena’s electricity assets in Victoria. The JESA contract includes a
comprehensive Performance Framework, with both Key Performance Indicators (KPIs) and Performance Health
Indicators (PHIs) monitored monthly.
To date, Zinfra Power Services has consistently achieved 95% of the KPIs outlined under the JESA – a testament to
its energy industry expertise and capabilities, as well as its continued identification of opportunities to improve and
deliver the JESA program of works prudently, efficiently and safely.
Collaboration and communication key to overcoming challenges
Zinfra delivers a comprehensive range of engineering, project management, construction, operations and
maintenance services, and its partnership with Jemena highlights how it is using its industry expertise and technical
capabilities to make a positive contribution to Australia’s energy infrastructure.
The scope of work for the JESA contract consists of preventative maintenance – including changing cross arms and
replacing poles – operational fault response, customer-initiated network augmentation such as new connections
and supply upgrades, and the delivery of capital projects initiated by Jemena.
According to the JESA Operations Manager, Vincent Marziale, one of the initial challenges was transitioning over
250 employees from the Jemena network field services team to Zinfra. Given Zinfra’s market position as a leading
service delivery partner for the utility industry, the organisation is experienced at this type of workforce transition,
and worked closely with HR specialists and the Jemena senior management to ensure effective employee
engagement throughout the transition.
Managing costs is essential on any project, and Zinfra implemented a number of measures to achieve cost savings
for Jemena in the first year of the JESA contract.
Some of these cost savings were achieved through a review of the JESA structure, which was completed in June
2019 and resulted in a workforce reduction.
Zinfra embraces continuous improvement and is always looking to understand, improve and innovate in the areas
where it can add most value.
As part of its flexible approach to streamlining contract costs, Zinfra explored different ways to refine its delivery
processes, which included the rollout of new technologies such as Multi Resource Scheduling (MRS), Digital Work
Order Management (DWOM) and Digital Round Trip (DRT).
In addition to the efficiencies provided by these platforms, there has also been increased uptake of automated,
Zinfra also partnered with Jemena to implement their new outage planning system, working closely with Jemena’s
control room to ensure the least amount of customers possible would be impacted by outages into the future.
A proven track record in safety and quality
Zinfra sets itself up for success by making sure it has the processes and reporting in place to continually monitor
how it’s tracking against its targets and can make adjustments as required.
Effective communication is also key, in terms of ensuring everyone in the project team understands the client’s
expectations, their role and what they’re accountable for.
“I think the first-year results of the JESA contract speak volumes to Zinfra’s ability to meet its client’s needs and
quickly adapt to a changing environment,” Vincent Marziale said.
Safety is Zinfra’s number one priority, and moving into the second year of the JESA contract, the Total Recordable
Injury Frequency Rate (TRIFR) remains at zero.
This outstanding safety performance is the result of a safety-first culture that has been nurtured over many years,
along with a dedicated subcontractor management team that oversees compliance for both the internal and
Zinfra is committed to building genuine relationships with its clients and communities.
Zinfra is also the lead contractor for the electricity network upgrades required for two other major Victorian
infrastructure projects: West Gate Tunnel and North East Link and is always looking to understand, improve and
innovate in the areas where it can add most value.
Delivering results through effective partnerships
Zinfra is passionate about delivering real value to each project’s end user, and Vincent Marziale explained that
Zinfra treats Jemena’s customers as its own.
“Asset owners such as Jemena are not only held accountable by the various regulators, but also by how satisfied
their customers are,” Vincent Marziale said.
“We have a very customer-focused approach. We partner with our clients to invest in technology to ensure we get
the best outcomes for customers – the first year of the JESA contract included implementation of a customer
portal for Jemena customers to submit applications for new electricity connections, improving the customer
experience and interface into the business.”
Zinfra also demonstrates a strong focus on achieving the right outcomes for its clients, working heavily with
Jemena to develop its capital operating works plan, which outlines and supports Jemena’s investments.
“Zinfra and Jemena partner throughout the year to develop, maintain and implement the most prudent efficient
and innovative work programs.” Vincent Marziale said.
“It’s about working together to ensure that Jemena’s entire program is delivered successfully with the optimum
amount of resources and a constant focus on the customer’s experience.”
