Peel

The Peel Microgrid is the first renewable industrial microgrid in Western Australia integrated across and servicing multiple green titled lots, and consists of 22kV embedded electricity distribution network, a connection to the South West Interconnected System grid and onsite renewable generation and battery storage assets.

Project Background

Peel Renewable Energy, a subsidiary of Zenith Energy, owns and operates the renewable electricity microgrid (Peel Microgrid). This supplies power to all customers at Nambeelup Kaadadjan, a large industrial and agri-business precinct located near Nambeelup, approximately 70km south of Perth and 7km north-west of the City of Mandurah, Western Australia.

The first stage of the 1,000 ha of Nambeelup Kaadadjan is being developed by Development WA’s Industrial Lands Authority and is a core element of the Western Australian State Government’s Transform Peel initiative.

Renewable Integration

The Peel Microgrid is the first renewable industrial microgrid in Western Australia integrated across and servicing multiple green titled lots, and consists of a 22kV embedded electricity distribution network, a connection to the South West Interconnected System grid and onsite renewable generation and battery storage assets.

Initially utilising a 1.2MW solar array and 2.5MWh Battery Energy Storage System (BESS), the microgrid’s onsite generation is anticipated to grow towards 30MW solar and 58MWh BESS over approximately the next decade. The Peel Microgrid provides Nambeelup Kaadadjan’s tenants safe and reliable electricity at cost savings of up to 30 per cent on relevant regulated tariffs, whilst at the same time delivering a minimum 50% renewable energy content to all customers.

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

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.

The Zenith Energy solution for this project was the construction of a 19MW power station, with primary power provided by a 10MW gas station with full diesel redundancy.

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:

  • 4MW DC Solar Farm and,
  • A 3MW/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”

Tanami

Newmont’s Tamami Gold Mine is an underground mine located 540 km north-west of Alice Springs, Northern Territory, Australia.

Project Background

Newmont’s Tanami Gold Mine is an underground mine located 540 km north-west of Alice Springs, Northern Territory, Australia.

Zenith currently operates two power stations at the Newmont Tanami site; the Dead Bullock Soak (DBS) station and the Granites Power Station (GTS).

The two stations are located 42km apart and are joined by 66kV overhead powerlines.

The two power stations combined to have a capacity of 101.5MW and were commenced in 2018.

Renewable Integration

In 2020 Zenith begun the “T2 Expansion” at Tanami. This expansion includes the installation of a Battery Energy Storage System (BESS) and additional gas generating units.

Once the expansion has been completed, the total Tanami project will comprise of the following:

  • 3 x Wartsila 8.7MW 20V34 Dual Fuel Generating Sets
  • 2x Wartsila 9.8MW 30V34 Gas Generating Sets
  • 4x 2.4MW Diesel Generating Sets
  • 11x 3.4MW Gas Generating Sets
  • 1 x 9.2MW / 9MWh Wartsila BESS

The BESS system will address a cyclic load demand and operate in parallel with the existing gas power station, and further reduce its carbon footprint.

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

Renewable Integration

In 2019 Zenith commissioned a 5.5MW PV solar power station to operate in parallel with the existing 19MW diesel fueled power station at Nova.

The solar power was designed to seamlessly integrate with the existing power station, using a control system designed to maximise the use of renewable energy while providing reliable and consistent power – a testament to the innovation and control systems capability of Zenith Energy’s engineers.

The system uses Zenith’s state-of-the-art cloud prediction and integration technology in order to predict cloud cover events. When large cloud coverage is predicted, the thermal generation is increased to offset the decrease in solar irradiation.

The numbers behind this system:

  • 11GWh per year in the first 3 years of operation
  • 3 million litres less diesel per year
  • 8,100 tonnes per year fewer CO2emissions per annum

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

“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.”

IGO Chief Operating Officer, Matt Dusci
