The 80 Percent Energy Deficit Problem Solved

South Africa’s mining sector is at a crossroads. We’ve seen incredible leadership and vision as mines across the country roll out on-site solar PV systems. It’s a move that shows a commitment to the planet and a desire to break free from an unreliable grid. But the truth is that even with the best on-site solar setup, most mines still rely on Eskom for over 80% of their power. At Red Rocket, we call this the 80% Problem. On-site solar, while a great start, typically only covers 15% to 18% of a large mine’s total energy needs. That leaves a massive deficit – energy that still comes from a coal-fed, increasingly expensive grid. At Red Rocket, we enable South African mines to operate totally independent from Eskom.

The Shortcomings of On-site Solar

Large-scale mining operations are the heartbeat of our economy, and they never stop beating. They draw massive, constant energy loads for ventilation, processing and dewatering – 24 hours a day, 365 days a year. Unfortunately, two things hold back on-site solar:

The Footprint: Most mines simply don’t have the surface area to install the number of panels needed to power heavy-duty industrial machinery.
The Gap: Solar only generates during the day, but a mine’s demand runs through the night.

According to research published in the Journal of Energy in Southern Africa, electricity costs for South African mining corporations rose from 7% to 20% of total operational expenses between 2007 and 2016. And according to PowerOptimal, Eskom tariffs surged by an eye-watering 1,172% from 2007 to 2026. That is more than six times the rate of inflation over the same period. 2027 does not look any better, with a 9.19% increase already approved. For a CFO building a five- or ten-year financial model, remaining on the grid is no longer really a viable option.

The Red Rocket Solution: Off-Site Energy Wheeling

Off-Site Energy Wheeling is the real game-changer. Red Rocket develops utility-scale wind or solar facilities at the most energy-potent sites in South Africa. Generated electricity is “wheeled” or transported over Eskom’s grid to you, the customer. Because the electricity you consume is generated by Red Rocket, Eskom credits your bill and only charges you for the use of their grid infrastructure. A bilateral agreement is concluded directly between the mine and the IPP, and the wheeling arrangement is formalised through the relevant grid operator under the regulatory framework administered by NERSA. This structure makes geography irrelevant. We can harness the fierce winds of the Northern Cape to power a mine in the heart of Limpopo. As long as your mine is connected to a medium- or high-voltage network and operates under a time-of-use tariff, you are eligible to step into the future of energy.

Predictability: The Greatest Competitive Advantage

In an unpredictable world, the smartest thing a CFO could do is to curtail and fix the price of energy. When you enter a 15-year Power Purchase Agreement (PPA) with Red Rocket, you stop being a victim of the next NERSA price hike. Consider the following two large mining operations: Mine A stays on the standard tariff. They are currently facing approved increases of nearly 9% for the next two years—and that’s the minimum. They have no recourse and no protection. Mine B partners with Red Rocket Trading. They lock in a 15-year PPA with a predictable, contracted annual escalation (typically around 5%). Their energy bill is no longer a source of anxiety – it’s a structured, forecastable line item. This allows for smarter capital allocation, better equipment investment cycles, and long-term planning that competitors simply can’t match. For Mine B, the savings can run into hundreds of billions of rands over the life of a contract.

Why Red Rocket is Your Partner in This Revolution

Not every energy company is built for the scale of South African mining. We are. Red Rocket is a fully integrated African IPP and a NERSA-licensed electricity trader. We don’t just facilitate deals; we build, own, and operate the energy funnel from creation to delivery. With 15 years of experience and over 22,000 MW of renewable energy capacity in development across the continent, we have the infrastructure and the fearless spirit to back up our promises. Our active portfolio – spanning more than 6 MW – means we already have the generation capacity and contractual expertise to solve the “80% Problem” for you right now.

Start Your Journey to Energy Freedom

The transition to a PPA is smoother than most people imagine. From our first conversation to a signed term sheet, the process usually takes between eight and twelve weeks.

The Review: We start with a no-obligation energy review. We look at your bills, understand your energy requirements, and see where the gaps are.
The Proposal: Within two to three weeks, we provide a tailored PPA proposal designed specifically for your operational needs.
The Execution: We handle the bilateral agreements and formalize the wheeling arrangements with the grid operator.

The South African and global energy landscape is rapidly shifting. Don’t wait for the next tariff hike to force your hand. Reach out to the Red Rocket team today to ensure the long-term sustainability of your venture.
