Current progress

Beyond the concept stage

The Riverbox prototype has been developed. We are now validating it through pilots and preparing to build the capacity needed for commercial deployment.

Current stage

Integration, testing & field validation

The Riverbox prototype has been developed. We are now completing system integration, testing and field validation of the first fully integrated pilot systems.

The current pilot-development phase is supported through an existing programme.

Pilot design

How each pilot site works

Site infrastructure

Small diversion weir, local penstock piping, a turbine house and a basic mini-grid distribution line to target clusters.

Anchor loads first

Priority for rural health posts, schools and milling equipment to raise capacity factor and stimulate local economic activity.

Community ownership

Ownership transitions to a village cooperative, with a modest monthly household tariff paid into a ring-fenced maintenance fund.

Short-term goals

Short-term goals

  • Complete and field-test the first fully integrated Riverbox pilot systems at varying capacities and operating conditions.
  • Validate mechanical, electrical and overall system performance under real field conditions.
  • Identify and prepare suitable sites for additional pilots and early commercial deployments.
  • Finalise the core engineering, fabrication and testing procedures required for repeatable production.

Installations — long-term goal

Reliable local power

Continuous electricity from small rivers, day and night, for communities beyond the grid.

Productive use

Power for agriculture, milling, cold storage, small enterprises and community services.

Local skills & jobs

Machinists, fabricators, welders, electrical technicians and installers trained in Zambia.

Clean energy

Displacing diesel and kerosene with renewable run-of-river hydropower — no large dam required.
