Zinfra drives efficiencies on the Jemena electricity network

In 2019, Jemena distributed 4,229GWh of electricity to 354,452 customer sites across Victoria
via 6,600km of overhead and underground powerlines. Zinfra played a significant role in
Jemena’s network performance, commencing the delivery of the operations and maintenance
contract on the Jemena Electricity Network (JEN) at the end of 2018, which has reinforced
Zinfra’s position as Australia’s leading provider of field services to the electricity market.

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

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

In addition to the efficiencies provided by these platforms, there has also been increased uptake of automated, system-based reporting.

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 external workforce.

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.

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.”
