the asia miner • volume 16 • issue 1 35 AROUND THE REGION Silkroad Nickel's subsidiary, PT Teknik Alum Service has entered into a new long-term mining exploraঞon agreement with Sinohydro Corporaঞon Limited and PT. Sepco II Indo. The contract value, based on the fixed price per tonne agreed under the agreement and the 6 million tonnes of nickel ore to be produced by Sinohydro Corporaঞon and PT. Sepco II, is esঞmated to be in excess of AU$90 million. Under the terms of the contract, Silkroad Nickel is responsible for compleঞng all land acquisiঞon related maers, applying and obtaining all necessary licenses and permits, and providing Sinohydro Corporaঞon Limited and PT. Sepco II Indo with the necessary data of the mining area. Both Sinohydro Corporaঞon and PT. Sepco II are responsible for excavaঞng and transporঞng the overburden, providing mining equipment, technical assistance, personnel and support needed to produce the nickel ore, maintaining the roads to be used for transporঞng the nickel ore and transporঞng the nickel ore. Mr Hong Kah Ing, Execuঞve Director and Chief Execuঞve Officer of Silkroad Nickel was pleased to strike the agreement with PowerChina. "PowerChina is amongst the world's top five largest contractors and engineering companies," says Mr Hong Kah Ing. "This Agreement gives us the impetus required to ramp up our producঞon levels to fulfil the requirements of our o\ake contracts and start the exploraঞon of new areas within our concession." Sinohydro is owned by Power Construcঞon Corporaঞon of China (PowerChina), a wholly state-owned company of the People's Republic of China. PowerChina is an integrated construcঞon group and its principal businesses include energy, power, construcঞon equipment and engineering and operaঞon management. PT. Sepco is a company in Indonesia, owned by PowerChina. Silkroad Nickel signs mining exploration agreement with Sinohydro Gold Fields' Granny Smith gold mine is set to install one of the world's largest renewable energy microgrids powered by more than 20,000 solar panels and backed up by a 2MW/1MWh baery system. The mining company has contracted mobile and modular power company Aggreko to design, build and operate the 8MW solar power generaঞon system along with the baery system at Granny Smith, which is located east of Laverton in Western Australia's Goldfields region. Gold Fields Execuঞve Vice President Australasia, Stuart Mathews, said the renewable energy microgrid is part of Gold Fields' vision of leadership in sustainable gold mining. "We are thrilled to reach an agreement with Aggreko for the design, installaঞon and operaঞon of this innovaঞve source of renewable energy which will generate nearly enough power to run the mine's processing operaঞons," Mathews said. The renewable power microgrid is expected to be operaঞonal by Q4 2019, and is seen as a welcome addiঞon to the company's suite of on-site energy soluঞons across other operaঞons working towards the reducঞon of the company's carbon footprint. Construcঞon of the renewable energy system is planned to commence in May and, when completed, will be one of the world's largest hybrid off-grid microgrids and integrated with Aggreko's exisঞng 24.2MW natural gas generaঞon. Aggreko AusPac Managing Director, George Whyte, said the solar, thermal and baery storage assets will be seamlessly integrated and managed by Aggreko's control so[ware plaorm – maintaining full system availability and opঞmising the lifeঞme of exisঞng thermal assets. "The solar-plus-baery system is projected to reduce fuel consumpঞon by 10-13 per cent and produce about 18 GWh of clean energy per year," Whyte said. "Gold Fields understands the performance, cost and environmental advantages for their operaঞon, as well as the need to integrate this resource into their system without compromising power supply reliability or mining producঞvity," he said. While the solar PV will reduce the need to run thermal generators, the baery plant will provide essenঞal services such as spinning reserve displacement, PV ramp rate control and transient voltage/frequency support. The current Granny Smith power staঞon was designed and installed by Aggreko in 2016 and the new hybrid power system, combined with a thermal staঞon expansion will meet the increased daily power needs of 24.2MW, with 12.2MW allocated to the Wallaby underground mine and the remaining 12 MW to the processing plant, associated faciliঞes and mining camp.
