Jundee

Northern Star Resources’ Jundee mine is an underground mining operation located in the Northern Goldfields region of Western Australia approximately 45 kms north-east of Wiluna and approximately 520 kms north of Kalgoorlie.

Project Background

Northern Star Resources’ Jundee mine is an underground mining operation located in the Northern Goldfields region of Western Australia approximately 45 kms north-east of Wiluna and approximately 520 kms north of Kalgoorlie.


Zenith commenced work on the power station in 2016.

Renewable Integration

Zenith subsequently introduced a renewable energy retrofit to the existing power system, integrating 24 MW of wind, 17 MWp of solar PV and a 12 MW / 12 MWh BESS alongside the existing gas generation.

The integrated system is designed to provide approximately 55% of the mine site’s power from renewable sources, significantly reducing reliance on fossil-fuel generation.

How Zenith is Leading the Sector

Zenith Energy’s renewable energy Power Purchase Agreement (PPA) with Northern Star Resources at Jundee supports the transition to a lower-carbon energy system. Zenith’s innovative renewable energy retrofit has positioned the company as a key player in reducing carbon intensity across the mining sector, further advancing their net-zero milestones.

Installed capacity

  • Gas: 34.2 MW
  • Diesel: 2 MW
  • Solar:17 MW
  • Wind: 24MW, Consisting of 4 x 6MW Goldwind Turbines with a rotor Diameter of 165M, and a total height of 212M.
  • BESS: 12 MW/12 MWh Battery Energy Storage System
  • Synchronous condensers: No Syncons Installed
  • Renewable energy fraction: The goal is for approximately 55% of the project’s energy needs to be met by renewable energy.

Commercial operation date (COD)

The Original Jundee power station began operations in 2016, with the first hybrid components commissioned in early 2024.

Contract term

Long-term Power Purchase Agreement (PPA) under a Build, Own, operate (BOO) model, recently extended until 2039.

Client’s decarbonisation objective

Northern Star Resources aims to significantly reduce its carbon emissions by incorporating renewable energy sources into the Jundee mine operation. With the addition of wind, solar, and battery storage, the Jundee site will cover 55% of its energy needs with renewable sources. This aligns with Zenith Energy’s goal to reduce its carbon intensity by 20% by 2025, from a 2020 baseline, which includes scope 1, 2, and 3 emissions.

Additional information

Zenith Energy has signed a renewable energy Power Purchase Agreement with Northern Star Resources for the Jundee operation. This PPA will support Zenith Energy’s interim net zero milestones and strengthen its relationship with Northern Star, with the renewable energy retrofit expected to significantly cut carbon emissions and increase the use of renewables at the mine.

Warrawoona

Warrawoona

Calidus Resources is an ASX listed gold company that is developing the 1.5Moz Warrawoona Gold Project in the East Pilbara district of Western Australia.

Project Background

Warrawoona Gold Project is in the East Pilbara district of Western Australia.

Power station comprises;

  • LNG Storage Facility
  • 8 x KTA50s, each with a capacity of 1.02MW
  • 4 x Jenbacher 616 each with a capacity of 2.68MW

Renewable Integration

After finalising the PPA, Zenith Energy was engaged by Calidus Resources to assess the viability of deploying a solar solution to offset emissions

The renewable solution that Zenith Energy developed included the installation of a:

  • 4.1MW DC Solar Farm and,
  • A 3.5MW/3MWh AC Battery Energy Storage System (BESS)

The solar farm will utilise modular technology, adding to Zenith Energy’s fleet of relocatable renewables.

The hybrid power station configuration will result in a reduction in gas use, which in turn results in a reduction in emissions, around 13 percent less than the initially contracted gas only station.

“Calidus is committed to carbon reduction as part of its ESG policy. This renewable micro grid is a cornerstone to our carbon reduction plan which includes the use of LNG not diesel and the ability of the LNG gensets to use up to 25% hydrogen. We are pleased to extend the relationship with Zenith to incorporate this renewables project, and look forward to its construction in the second half of this year”

Plutonic – Project previously under Zenith Energy contract

Plutonic – Project previously under Zenith Energy contract – Project previously under Zenith Energy contract

Superior Gold’s Plutonic Gold mine (the producing underground operation) is 800km north-east of Perth. It is one of the largest gold mines in Western Australia in terms of cumulative production, with both open pit and underground production.

Project Background

Superior Gold’s Plutonic gold mine (the producing underground operation) is 800km north-east of Perth. It is one of the largest gold mines in Western Australia in terms of cumulative production, with both open pit and underground production.

Superior Gold is listed under the TSX Venture exchange with 100% ownership and operation of the Plutonic Gold Operations that includes the Plutonic Gold mine.

Zenith is providing 16MW of power generation solution through the use of our gas generation sets.

The Plutonic Operation commenced production in 1990 and currently sources ore from the existing underground and open pit resources

Nova

Nova

The Nova Nickel Mine is located in the Fraser Range, 380 km from the Port of Esperance and was commenced in 2015

Project Background

The Nova Nickel Mine is located in the Fraser Range, 380 km from the Port of Esperance and was commenced in 2015

The operation is 100% owned by IGO, an ASX listed mining and exploration company that produces gold, nickel, and copper operations

Zeniths initial power generation solution at Nova was a 19MW diesel station which included:

  • 5 x 3MW Medium Speed Diesel Generating Sets
  • 3x 1.7 MW High Speed Diesel Generating Sets

How Zenith is Leading the Sector

Zenith and IGO are continuing their efforts to reduce emissions at the Nova operation by optimising the system to enable “Engine Off”.

This innovation will allow for diesel generation to be turned off and replaced with either stored or generated renewable capacity for significant periods during daylight hours. This is an industry first.

To achieve Engine Off, Zenith will install the following:

  • Additional 10.2MW of relocatable solar to enable renewable generation in excess of 100% of site demand
  • BESS system to provide smoothing during clouding events and capture additional solar spill where possible
  • Synchronous Condensers to provide grid forming and reactive support

Installed capacity

  • Thermal: 20.2 MW via diesel generation
  • Solar: 16.3 MW
  • BESS: Battery Energy Storage System of 12MW/12 MWh
  • Synchronous condensers: 2 x 2.8MVAr Syncron.
  • ‘Engine Off’ enabled – the ability to operate on 100% renewable energy when conditions allow.

Commercial operation date (COD)

The Original Nova power station began operations in 2015, with the first hybrid components commissioned in 2019.

Contract term

10 Years.

Client’s decarbonisation objective

IGO’s Nova Project aims to reduce its carbon emissions by maximising the use of renewable energy. The hybrid power plant, which enables 100% renewable operation during specific periods, is part of IGO’s broader commitment to sustainability and lowering its environmental impact. This hybrid solution allows the mine to minimise reliance on fossil fuels while enhancing operational efficiency through renewable integration.

“It’s an important next step on the journey to Net Zero. It will set a new industry benchmark in terms of renewable energy integration, and reduction of emissions at mine sites. It sends a message to the industry that powering an entire site 100% with renewables is possible today.”

Mt Morgans

Mt Morgans

Dacian Gold’s Mt Morgans operation is located 20km west of Laverton, being approximately 750km northeast of Perth in Western Australia. The operation is amongst a very highly endowed gold field project with multi-million ounce deposits(Dacian Gold, 2022).

Project Background

Dacian Gold’s Mt Morgans operation is located 20km west of Laverton, and approximately 750km north-east of Perth in Western Australia. The operation is amongst a very highly endowed gold field project with multi-million ounce deposits (Dacian Gold, 2022).

Dacian Gold is an ASX listed company and is a mid-tier gold producer, with its main production coming from Mt Morgan, and is pursuing multiple growth options to extend the operation’s mine life along with the production of gold.

Zenith Energy is providing 19.8MW of power generation solution through the use of our gas generation sets.

The power supply commenced since 2017.
