Seriti Green

What Seriti Green does

Seriti Green is a South African black-owned Independent Power Producer (IPP) founded in 2022 through Seriti Resources' R900 million acquisition of Windlab SA. The company develops, constructs, and operates utility-scale wind and solar renewable energy projects, with a portfolio of 23 projects representing more than 4GW of capacity across South Africa and East Africa. Operational assets include Amakhala Emoyeni (134MW, Eastern Cape), West Coast One (94MW, Western Cape), Msenge Emoyeni (69MW, Eastern Cape, exporting since October 2024), and Iziduli Emoyeni (84MW contracted). The flagship Ummbila Emoyeni in Mpumalanga is a ~900MW hybrid renewable facility, the largest of its kind in South Africa, with Phase 1 (~155MW) under construction and full commissioning targeted for 2027. An adjacent Phefumula Emoyeni project (1.3GW) is in early development. East African operations are conducted through a 75%-owned subsidiary, Hewani Energy (with Japan's Eurus Energy holding 25%), covering a 620MW pipeline: Emarti Hewani (100MW, Kenya), Miombo Hewani (300MW, Tanzania), and the Meru County Energy Park (220MW hybrid, Kenya).

The company's core technology is built around proprietary atmospheric wind modelling and energy analysis tools, inherited via Windlab SA, used to identify premium greenfield wind sites and optimise project feasibility and performance. Ownership is structured as a consortium: Seriti Power (54.19%), VennEnergy (15%), RMB (15.41%), and Standard Bank (15.41%). Seriti Power — part of Seriti Resources, a major South African coal miner — is the controlling shareholder, with CEO Peter Venn (formerly of Windlab Africa) leading operations. Standard Bank and RMB serve as both shareholders and project financiers, with Standard Bank having funded the 465MW Ummbila Emoyeni portfolio in 2025 as part of a R47.1 billion green finance mobilisation.

Seriti Green monetises primarily through long-term Power Purchase Agreements secured via South Africa's REIPPPP procurement programme and direct corporate offtake contracts with industrial users. The first phase of Ummbila Emoyeni is contracted to supply 75% of Seriti's own coal mining power requirements via Eskom grid wheeling. Additional revenue comes from selling development-stage projects to third parties (e.g., Msenge, West Coast One, Amakhala via partnerships with ACED, Cennergi, and ENGIE). The primary customer segments are national power utilities (Eskom), mining and heavy industry, and regional East African county governments seeking to meet clean energy targets.

Revenue model

1. Power Purchase Agreements (PPAs): Long-term power purchase agreements with offtakers including Seriti's own coal mining operations, with energy wheeled through the Eskom grid. The first phase of Ummbila Emoyeni (~155MW) will supply 75% of Seriti's coal mining power requirements.
2. REIPPPP Bidding: Projects bid into South Africa's Renewable Energy Independent Power Producer Procurement Programme, securing government-backed offtake agreements that provide revenue certainty for large-scale renewable projects.
3. Project Sales: Some developed projects are sold to third parties including Iziduli Emoyeni, Umsinde Emoyeni, Khangela Emoyeni, Ishwati Emoyeni, Msenge Emoyeni (partnership with ACED), West Coast One, and Amakhala Emoyeni (partnership with Cennergi).
