I am all for championing going green in industries and across the board, with that consideration, I am watchful of South Africa’s energy story which has long been defined by scarcity, uncertainty, and the hum of diesel generators. But, beneath the noise, a quieter and more deliberate shift has been taking shape, one led not by politicians, but by boardrooms and building managers who have decided that waiting for the grid to recover is no longer a strategy.

Growthpoint Properties’ acquisition of a 30% stake in the R390 million Boston Hydroelectric Plant marks a new chapter in this silent revolution. This while many my think this is about a real estate company buying into clean power, we put it to you that It’s about what corporate leadership looks like when sustainability becomes a form of self-preservation, and strategy.

Situated within the Lesotho Highlands Water Scheme near Clarens, the Boston Hydro plant is now generating 24/7 renewable energy, feeding electricity into the national grid and directly powering 23 of Growthpoint’s flagship properties, from Sandton Central to Cape Town’s Foreshore. Through a partnership with Etana Energy and Serengeti Energy, the initiative reimagines how commercial buildings can source electricity, wheeling clean energy across the grid instead of waiting for rooftop space or policy reform.

Growthpoint’s e-co₂ initiative (pronounced “eco-two”) takes this a step further. It allows tenants and  thousands of businesses across sectors, to plug directly into zero-carbon electricity and verifiably reduce their Scope 2 emissions. Our country is still wrestling with unreliable power and slow public-sector reform, this corporate-led model is nothing short of revolutionary. It shows how environmental consciousness can merge with financial pragmatism, saving costs, ensuring supply, and advancing climate accountability.

Over the past decade, Growthpoint has quietly built one of South Africa’s largest private renewable energy portfolios, investing over R1 billion into solar, now blending that with hydro and soon wind. Nearly 40% of its total electricity demand will soon come from renewables. But beyond the impressive statistics lies something more symbolic, a pivot in how the property sector defines value.

Where once “location, location, location” was the mantra, the new premium is “energy, efficiency, and ethics.” Buildings should no longer just be spaces; they must be nodes of sustainability, and tenants should no longer just be renters; they must be participants in a cleaner economy.

The Growthpoint–Etana–Serengeti partnership, underpinned by blockchain-certified renewable tracking (I-RECs), represents a collaborative ecosystem that may well set the tone for corporate South Africa’s next era, one that combines transparency, environmental stewardship, and private-sector innovation in ways that government policy often struggles to match.

While “going green” is still treated by some as PR language, Growthpoint’s approach shows what happens when the rhetoric matures into infrastructure. Hydropower flowing through office corridors might once have sounded poetic; today, it’s just good business.
