How does the REIPPP program work?

This regulatory mechanism was designed to accelerate the deployment of renewable energy infrastructure by leveraging private capital and reducing the financial burden on the state-owned utility, Eskom. The programme functions as a competitive auction process that selects independent power producers (IPPs) based on a combination of price and non-price criteria, ensuring both economic efficiency and strategic national benefits.

Procurement and Auction Mechanism

Under the REIPPP framework, the Department of Renewable Energy issues requests for proposals (RFPs) for specific renewable energy technologies, including solar photovoltaic and concentrated solar power. Private developers, such as the Zeerust Power Company, submit bids that detail the proposed project’s technical specifications, financial structure, and projected levelized cost of energy. The selection process evaluates these bids through a rigorous scoring system. While the price per kilowatt-hour is a primary factor, the programme also awards points for local content and socio-economic development initiatives. This dual-criteria approach encourages investors to integrate local supply chains and create employment opportunities within the host communities, thereby maximizing the broader economic impact of the energy infrastructure.

Financial Structuring and Risk Allocation

A critical component of the REIPPP model is the financial structuring of the projects, which are typically privately owned and privately funded. This structure reduces direct fiscal exposure for the government while attracting foreign direct investment. The programme mitigates investment risk through long-term Power Purchase Agreements (PPAs) signed between the selected IPPs and the off-taker, usually Eskom. These contracts guarantee a stable revenue stream for the duration of the concession period, providing the financial certainty required to secure debt financing for capital-intensive solar installations. The regulatory framework also defines the allocation of risks, such as currency fluctuations and feed-in tariff adjustments, ensuring that the financial viability of projects like the 75 MW Zeerust facility is maintained over their operational lifespans.
