largely untapped.

Zambia's energy deficit is a structural opportunity. Our EaaS model is built to capture it at scale — validated bottom-up from real customer data.

TAM

$2.1B

Total Addressable Market

All Zambian households and SMEs — the full energy market opportunity across the country.

SAM

$480M

Serviceable Addressable Market

Urban households and SMEs addressable by our EaaS model. Based on 1.6M urban households at $100/month + SMEs at $200/month.

SOM

$38M

Serviceable Obtainable Market

Our 5-year capture target at 8–10% penetration of the urban market — a conservative, bottom-up validated figure.

What we do

Powering communities.
Building the grid of tomorrow.

We design, install, and finance clean energy systems — and are building the subscription infrastructure to make energy access permanent across Sub-Saharan Africa.

Solar Energy Systems

Turnkey solar and battery installations for residential and commercial customers. Designed, installed, and supported end-to-end by our team in Zambia.

Battery Recycling & Upcycling

Recovering and repurposing lithium batteries from the regional market — reducing waste, lowering costs, and closing the loop on clean energy infrastructure.

Energy-as-a-Service

Our next frontier: a subscription model that removes the upfront barrier entirely. Customers pay monthly for clean energy — we own and maintain the system.
