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.
