Energy solutions provider Aggreko has finalised a landmark power purchase agreement (PPA) with international mining company Harmony Gold for the Eva copper mine project in northwest Queensland, Australia, paving the way for the development of that country’s largest offgrid renewable hybrid power facility. The PPA – with a minimum term of 15 years – will see Aggreko build, own and operate the renewable hybrid power facility, supplying safe, reliable and lower-carbon energy to support the construction and operation of Harmony’s new copper mine.
