The most important piece of energy infrastructure in a village without a grid is not a solar panel. It is a charged battery you can carry home. Jaza Energy has built its entire business on that simple, portable fact, and its customers have carried those batteries back and forth more than three million times [careers-page.com].
Founded in 2015, the Halifax-based company operates a last-mile solar utility in off-grid communities across Tanzania and Nigeria. Its model is a physical network: solar-powered energy hubs, built locally in Dar es Salaam, where portable lithium-ion battery packs are charged [Entrevestor.com]. Households rent these "Jaza Packs" for daily or weekly fees, using them to power lights, phones, and small appliances, before returning the depleted units for a fresh swap [Jaza Energy, retrieved 2024].
The Wedge is a Woman with a Shop
Jaza's primary innovation is distribution. Each hub is operated by a local micro-retailer, known internally as a "Jaza Star" [Jaza Energy, retrieved 2024]. These are overwhelmingly women entrepreneurs who run the hubs as their own businesses, handling customer relationships, swaps, and payments. The company provides the hardware, training, and backend software; the Star provides the trust and daily presence.
This model turns a capital-intensive infrastructure problem into a franchisable, income-generating opportunity. Each hub, according to project descriptions, can serve up to 300 households [EEP Africa].
A Decade of Quiet Traction
Jaza has been at this for nearly a decade. Its funding history is fragmented across impact investors and development funds, with total capital raised estimated between $5 million and $7.8 million [CB Insights] [PitchBook].

Traction is measured in swaps and people reached. The company reports over 3 million battery swaps since 2022 and says it provides approximately 225,000 people with access to clean energy [careers-page.com].
The Unit Economics of Displacement
The company states that every hour of light provided by a Jaza pack displaces kerosene or diesel [ecohubmap.com]. The business must compete on price and convenience. Its primary incumbent is the existing energy economy of the off-grid household: bottled gas, kerosene, disposable batteries, and cheap, polluting generators. Its bet is that a centralized, high-quality solar charging station, paired with durable, swappable batteries, can achieve that.
Where the Grid Isn't Coming
In Sub-Saharan Africa, over 500 million people still lack reliable electricity access. Companies like Zola Electric, M-KOPA, and Bboxx have built substantial businesses selling or financing solar home systems (SHS) to this market. Jaza's swap model offers a different wedge. It requires no large upfront payment or credit check from the customer, just a small rental fee. It also centralizes the most expensive hardware at the hub, rather than putting a panel on every roof.
The Next Twelve Months
The path forward involves more of the same. The company will need to prove it can replicate its hub-and-star model in new territories without sacrificing unit economics or service quality. Key things to watch will be any announcement of a Series B round to fund expansion, partnerships with larger distributors or telecoms to accelerate hub placement, and deeper data on customer retention and battery cycle life.
