Secha Capital — Why We Invested: Plentify
Secha Capital invested in Plentify because they’re quietly building one of the most important distributed energy assets of the next decade, possibly the missing piece in the global energy stack — and this company could only have been built in the unique energy conditions in South Africa.
So what are they building? A virtual battery hiding inside every ordinary home.
Plentify takes the flexible load in buildings and turns it into a virtual battery that can be orchestrated, not just switched on and off.
That simple idea unlocks a lot.
A new way to allocate energy: Use the appliances the world already owns as storage-like assets, and orchestrate them with AI-grade intelligence behind the meter.

The global energy landscape is undergoing a seismic shift. As we produce more variable renewable power, a universal problem emerges: demand does not align with supply. Every grid, from developed to emerging market, is grappling with midday solar peaks, evening demand spikes and the immense cost of building new plants.
This misalignment creates instability and drives up costs. The solution is not about building more plants or expensive grid-scale batteries. The solution is already inside hundreds of millions of homes.
Globally, there are ~300 million electric water heaters, representing 900 GW of instantaneous load globally and 2,850 GWH of energy storage.
This is a virtual battery equivalent to 75% of the entire US capacity already installed and paid for. Plentify is unlocking this overlooked asset to solve the core challenges of the energy transition.
2. Our solution: The Virtual Battery in Every Home
Every serious energy OEM and utility is converging on the same problem: controlling flexible load behind the meter. Very few companies can do this across hardware, software, and fleets.
Plentify turns the flexible load in homes into an intelligent energy asset. They built a virtual battery that can be orchestrated with precision, not just switched on and off. The solution began with the electric geyser (water heater) — and has since evolved.
Most homes already have a battery — it’s just full of water instead of lithium. By installing a low-cost device and installing it on the geyser and connecting it to Plentify’s AI-powered platform, Plentify transforms it into a controllable, storage-like asset. This allows them to shift energy demand to match solar generation and off-peak tariffs, improving grid reliability and lowering household bills, all without requiring any lifestyle change or new capital expenditure from the homeowner.
Because this intervention happens behind the meter, Plentify creates value for the entire energy ecosystem:
Developers & IPPs / PPA sponsors — reduce required battery size, boost solar self-consumption, and strengthen project returns and coverage ratios.EPCs and solar installers — sell smarter systems without oversizing storage, and manage fleets from a single dashboard.Landlords and estate owners — arbitrage time-of-use tariffs at a building or estate level, not just per unit.Homeowners and renters — pay less for electricity, with more predictable bills, without thinking about it.
Instead of asking people to buy more hardware, Plentify leverages the current infrastructure.
3. Why Plentify Wins: SA’s Competitive Advantage and Plentify’s Moat Trajectory
a. Forged in the toughest market
Plentify exists in its current form because South Africa forced it into existence.
South Africa combines conditions you rarely see together:
Chronic grid instability — load-shedding is a regular feature, not an edge case. Behind-the-meter resilience isn’t a nice-to-have; it’s survival.A subsidy-free energy transition — no generous feed-in tariffs cushioning the economics. Products must stand on their own cash flows for very price-sensitive customers.A perfect load to hack — electric geysers are ubiquitous, large, and timing-insensitive. Nobody cares when they run, only that there’s hot water. That’s an ideal flexibility lever.Harsh constraints on cost and reliability — high tariffs, voltage issues, diverse housing stock, low ability to absorb failure.
Those constraints forced a very different design:
Use existing appliances as the “battery” instead of relying on expensive new hardware.Focus on algorithms and orchestration, not just metal and lithium.Build systems that work without subsidies, under real grid stress.
Once you can solve for South Africa, rolling out into Portugal, Brazil, Australia or the UK — with time-of-use tariffs, better grids and more affluent consumers — is not an experiment; it’s a scale-up.
We’ve seen this movie before:
Mobile money born in Kenya, then exportedPay-as-you-go solar born in East Africa, then scaledSME fintech born in Brazil, then globalized
Plentify is that same exportable pattern — but for distributed flexibility and home energy management.
b. An intelligent, multi-layered platform
Plentify started with hardware because that was the fastest wedge into the home. But the real asset is the intelligence and orchestration on top:
Edge devices (Bots)
On geysers and increasingly on broader loads behind the meterBuilt to be low-cost, robust and easy to deploy at scale
Data & AI
Learns usage patterns, appliance behaviour and local grid conditionsOptimizes when to heat water, charge batteries, and pull from the grid or solar
Fleet orchestration
A platform that lets partners — solar companies, landlords, utilities — manage thousands of homes as a single, flexible resourceIn effect, a virtual power plant made up of flexible loads plus storage, not just big standalone batteries
c. A Virtual Power Plant (VPP), Distributed Energy Resource (DER) and Independent Distributed Power Producer (IDPP) thesis that doesn’t depend on US-specific infrastructure
By aggregating tens of thousands of flexible loads into a distributed “virtual battery,” Plentify provides grid services traditionally supplied by large generators. Unlike simple demand-side management, its controllable assets actively stabilize the grid — absorbing excess energy when frequency rises and releasing it when it falls — making Plentify a true virtual power plant.
This capability is increasingly critical. In April 2025, the Spanish-Portuguese grid collapsed after frequency and voltage swings pushed parts of the system out of sync, underscoring how renewable-heavy grids require fast, distributed frequency support to prevent cascading failures.
Plentify delivers that support by orchestrating geysers, heat pumps, and other flexible loads at utility scale. At the same time, its AI platform smooths peak demand and arbitrages time-of-use tariffs for multi-dwelling buildings, lowering infrastructure costs and stabilizing bills for residents — while giving utilities a scalable partner to keep the lights on.
From a US venture capital perspective, Plentify doesn’t look like standard climate deal flow:
Plentify combines elements of hardware, software, and project finance, making them infra-relevant enough for strategics but software-rich enough for venture returns.
Secha’s thesis doesn’t depend on high penetration of expensive home batteries or EVs; it works with the appliances that already exist globally.
This gives Plentify a defensible, capital-efficient, and globally relevant position that is difficult to replicate.
And that is why we invested in and are so proud to partner with Plentify.
