Construction begins on mining giant BHP's initial off-grid solar-storage project

• Construction has started on BHP's "first off-grid large-scale renewable resource project", completing 38 MW of solar energy and a 10.1 MW/5.4 MWh battery energy storage system (BESS), at 2 nickel mines in Western Australia which supply Tesla for usage in electrical lorry (EV) batteries.

The Northern Goldfields Solar Project will certainly consist of a 27.4 MW solar farm at Mt Keith and a 10.7 MW solar farm with the BESS at close-by Leinster. It will certainly assist replace power currently supplied by diesel and gas and reduce scope 2 exhausts at both mines by 12%, or 54,000 tonnes of CO2e, and will certainly begin creating solar power in November.

This will certainly bolster BHP's trip to ending up being net no but additionally shore up the energy-intensive mines' energy supply and reduce expenses for transporting and burning diesel, and the group is just one of lots of mining companies launching such projects in Australia and in other places.

BHP is investing AU$ 73m (US$ 52m) in the project which is being developed and run by worldwide renewables group TransAlta Renewables, which has acquired German company Juwi for engineering, procurement and construction (EPC) tasks.

The sites will supply electrical energy to BHP's mines under a power purchase agreement (PPA) with TransAlta which runs to 2038, and the two parties have actually consented to determine potential sites for 40-50 MW of wind generation which would further reduce scope 2 emissions at the mines by 30%.

BHP Nickel West Asset President Jessica Farrell kept in mind that it is BHP's "initial off-grid large-scale renewable energy project across our worldwide procedures," and it likewise marks TransAlta's initial renewable resource project in Australia.

Energy firm EDL claims there has to do with 2 GW of off-grid energy need in Australia, and that around $2.5 bn of financial investment will certainly be needed to fulfill half of this with renewables.

The nation has been a hotbed of such projects just recently.

Last week IGO Limited announced that solar-plus-storage would be set up at its Nova copper-cobalt-nickel mine at Fraser Range allowing the site to briefly operate 100% renewable energy. Rio Tinto revealed plans to set up a 4MW solar and 4MWh BESS at its Weipa bauxite mine in September, with construction anticipated to start later this year.

The group's solar solar-wind-storage system completing 28.25 MW, of which 8.25 MW is storage, at its QMM ilmenite mine in Madagascar is even more along with solar procedures expected to begin in Q2 2022 and wind by the end of the year. It needs to eventually offer 60% of the mine's power.

Somewhere else in Africa, tools maker Caterpillar lately provided 7.5 MW of battery storage to the microgrid powering the Kibali gold mine in the Democratic Republic of the Congo (DRC).

In April last year, an off-grid hybrid energy system at gold mine Fekola, Mali, went on the internet with 30MW of solar PV and a 17MW/15.4 MWh BESS. Across the Atlantic, Energy-Storage. news reported recently that technology group Wärtsilä had actually won a contract to offer the South American nation Suriname's first-ever utility-scale energy storage system, a 7.8 MW/7.8 MWh BESS to an unrevealed cash cow.
