South African independent power producer Mulilo has successfully reached financial close on the Hartebeesfontein battery energy storage system (BESS) project, a 77 MW/308 MWh facility located near Klerksdorp, in the North West.
This is Mulilo’s second renewable-energy project to be executed within the Matlosana local municipality, which is strategically located near State-owned Eskom’s Hermes main transmission substation.
The Hartebeesfontein BESS project was awarded under Bid Window 2 of the Battery Energy Storage Independent Power Producer Procurement Programme, through which Mulilo secured five of the eight projects awarded.
The project is designed to provide system support through its 308 MWh storage capacity and will supply ancillary services to the National Transmission Company South Africa (NTCSA) under a 15-year power purchase agreement.
Mulilo says the successful financial close of the Hartebeesfontein BESS project was made possible through collaboration between both the public and private sectors, supported by key partners, including the Department of Electricity and Energy, the Independent Power Producers Office, NTCSA and Eskom, along with Mulilo’s shareholders, Copenhagen Infrastructure Partners (CIP) and Norfund.
