Mulilo, a leading Independent Power Producer (IPP), has been awarded four projects under Round 3 of South Africa’s Battery Energy Storage Independent Power Producers Procurement Programme (BESIPPPP). These projects will deliver a combined 493 MW / 1972 MWh of Battery Energy Storage Systems (BESS) installations under 15-year power purchase agreements with Eskom.

All awarded projects are located in the Free State, South Africa and will include:

Erfdeel BESS (123MW/ 492MWh)
Retreat BESS (123MW/ 492MWh)
Bloemhoek BESS (124MW/ 496MWh)
Vanilla BESS (123MW/ 492MWh)

This latest achievement follows Mulilo’s success in Round 2 of BESIPPPP, where the company secured five BESS projects. With this Round 3 win of four projects, Mulilo further solidifies its position as South Africa’s leading IPP in the deployment of BESS technology.

To date, Mulilo has successfully participated in 12 of the 18 projects awarded under BESIPPPP, whilst taking majority ownership and a lead role in 9 of the awarded projects. In total, this amounts to 1.134 GW/ 4.536 GWh in the BESS 1-3 Bid Windows, a total market share of 65%.

Mulilo’s continued success is underpinned by the South African government’s efforts to address a constrained electricity network, support the integration of renewable energy and reduce reliance on an ageing coal fired power generation fleet.

Mulilo’s CEO, Jan Fourie, commented: “BESS is a vital solution for South Africa’s energy sector. It provides grid stability, enhances dispatchability of renewables, reduces load shedding, and optimizes costs. Being named Preferred Bidder in BESIPPPP Round 3 underscores our leadership in BESS and our commitment to building a low-carbon, resilient energy future the country.”

Mulilo currently operates 420 MW of wind and solar projects, with 764 MW under construction and more than 1,500 MW targeted for Financial Close by December 2025.
