South Africa’s renewable-energy landscape completed one of its most consequential transactions of the year when Cennergi Holdings, the green-energy subsidiary of Exxaro Resources, acquired ACCIONA Energía’s majority stakes in the 138 MW Gouda Wind Farm and 75 MW Sishen Solar Plant.
The R1.7–R1.8 billion ($95–$100 million) deal instantly elevates Cennergi’s operating footprint from 200 MW to 317 MW net, while adding 80% of the O&M business that services both sites.
With 180 MW already under construction, Cennergi is now tracking a 500 MW portfolio, enough to power roughly 400,000 homes and cut 500,000 tonnes of CO₂ annually.
Behind the scenes, Standard Bank Corporate & Investment Banking acted as exclusive financial adviser, steering a complex cross-border carve-out that blended Spanish sellers, South African energy regulators, BEE structures and community trusts into a single, fast-moving transaction.
For a country building more than R100 billion in renewables to end load-shedding, the deal shows how strategic brownfield acquisitions are speeding ahead of capacity auctions.
Cennergi, Exxaro’s wholly owned renewables arm, already sits among South Africa’s most experienced IPPs, with two wind farms online and a development pipeline exceeding 1 GW. Gouda and Sishen, both winners of the REIPPPP Bid Window 2 slot, fit neatly into that strategy.
Each carries a 20-year take-or-pay PPA with Eskom running to 2034/35, underwritten by the National Treasury, giving Cennergi inflation-linked cash flows in an era of rising rates.
Before the transaction, ACCIONA held 54.9% of each asset, with Royal Bafokeng Holdings (25.1%), Soul City (10%), and community trusts (10%) rounding out a deliberately inclusive ownership mix.
Cennergi retains that BEE architecture post-sale, a crucial condition for regulatory approval and community continuity.
Standard Bank’s CIB team, led by Thando Mbelu, brought deep credentials. Having advised on 5 GW-plus of South African IPPs since 2011, including Mainstream’s landmark R10 billion disposal, the bank’s familiarity with PPAs, regulatory hurdles and ESG-linked project structures allowed it to compress a typically year-long process into just six months.

How the Deal Was Engineered
Standard Bank’s advisory mandate spanned the full lifecycle of the transaction, from valuation to regulatory close. Its role is clearest in the structure it delivered:
| Phase | Standard Bank’s Role | Key Outcomes |
|---|---|---|
| Strategy & Valuation | Market scans; DCF valuation; scenario analysis | Enterprise value set at R1.7–1.8bn; PPAs priced at 10–12× EBITDA |
| Due Diligence | Technical audits; ESG and community reviews | Identified O&M efficiencies; safeguarded 200+ jobs; preserved BEE and community trusts |
| Structuring & Negotiation | Carve-out design; tax optimisation; PPA transfer frameworks | Secured 80% of O&M unit; maintained Soul City and community programmes |
| Closing | NERSA/DMRE approvals; transitional O&M handover; funding advisory | Smooth ownership transfer; freed Cennergi capex for 180 MW pipeline |
The acquisition is funded entirely from Exxaro’s balance sheet, strengthened by earlier coal asset disposals that left it with R10 billion in cash, meaning no acquisition debt and a clear path to 15%+ ROE on the renewables book.
While South Africa’s REIPPPP tenders remain central to climate commitments, the backlog around Bid Window 7 and connection constraints at Eskom have made seasoned brownfield assets extremely valuable.
Gouda and Sishen are proven performers: 98% availability, roughly 500 GWh combined annual output, and established local supply chains in the Western and Northern Cape.
For Cennergi, absorbing seasoned plants avoids the delays associated with permitting, grid studies and supply-chain bottlenecks. For South Africa, it adds reliable capacity immediately, supporting the drive to eliminate load-shedding and meet its 20 GW renewables target by 2030.
The Outcome
With Gouda and Sishen now anchored on its balance sheet, Cennergi jumps to 317 MW operating, 180 MW under construction, and a clear glidepath to 500 MW.
For Exxaro, the assets broaden green revenue by more than 20%, add predictable inflation-linked earnings out to 2035, and solidify its diversification away from coal.
For South Africa’s grid, the deal adds dependable renewable power without waiting for the next auction window.
For the market, it shows how Standard Bank’s advisory muscle sharpened over a decade of IPP transactions can accelerate renewable deployment faster than public tenders alone.
