Defeat Winter Peak Tariffs and Protect Your Bottom Line

In the world of retail property, winter is harsh. You see it in the numbers: despite high occupancy and premium tenants, net yields are under pressure. It is not just inflation or maintenance—those are expected year-round costs. In winter, it is the staggering impact of peak electricity tariffs that does the most damage to your bottom line. For property companies and retail landlords, the 24/7 cooling requirements of food chains and anchor tenants draw a massive peak-time electricity bill that often outpaces rental growth. At Red Rocket, we don’t just generate and trade power; we are a family of energy rebels dedicated to helping retail businesses stay profitable by reclaiming control over winter peak grid costs.

The 5x Multiplier: The Financial Reality of Winter Cooling

Retail landlords with food-chain tenants face a unique challenge: the cooling baseload is non-negotiable. Unlike lighting or HVAC, which can be optimised or dimmed, industrial refrigeration must run 24/7 to protect stock and maintain cold-chain integrity. Under the Eskom Megaflex and municipal Time-of-Use (TOU) structures, the “High Demand” (Winter) period carries a heavy premium. During these peak hours, the tariff can be as much as five times higher than the standard off-peak rate. When a supermarket’s refrigeration draws its heaviest load during these windows, the landlord effectively subsidises the grid’s inefficiency. Without a strategic intervention, these seasonal spikes directly erode your net operating income (NOI). To illustrate, consider the winter peak tariffs for 24/7 cooling baseloads:

Season	TOU Period	Energy Charge (c/kWh)
Summer (Sep–May)	Peak	~220 – 260
	Standard	~90 – 120
	Off-peak	~40 – 60
Winter (Jun–Aug)	Peak	~600 – 750
	Standard	~120 – 180
	Off-peak	~50 – 80

Peak Shaving: A Strategic Solution to the Winter Blues

To combat these spikes, Red Rocket implements a technical strategy known as Peak Shaving. Peak Shaving is a power continuity solution that integrates a battery energy storage system (BESS) with long-term renewable energy. By using an energy storage system, a property can “charge” during off-peak hours (when electricity is cheapest) and “discharge” that stored energy during expensive winter peak windows. When combined with a renewable PPA, the system ensures that the 24/7 cooling load is met with clean, fixed-cost power, effectively “shaving off” the most expensive peak tariffs from your electricity bill.

Fearless Innovation for Property Funds

Red Rocket is more than an independent power producer; we are partners in your long-term viability. We believe that for a retail property owner, a commercial backup power system must do more than just keep the lights on—it must actively increase yield. Our commercial energy storage solutions are designed to integrate seamlessly into existing retail infrastructure. We provide:

Cost Stability: By bypassing winter peak rates, we turn a volatile operational expense into a predictable, manageable line item.
Sustainability at Scale: We help landlords transition to load-shedding solutions that are green, quiet, and aligned with international ESG mandates.
Revenue Protection: By lowering the total cost of occupation, you ensure your tenants remain viable and your rental yields remain protected.
