Hydro
Energy sovereignty for the Kingdom of Eswatini.
PowerLink's first international development initiative is an early-stage project in Eswatini, designed to convert stranded canal flow, waste streams, and solar into reliable baseload — intended to anchor a domestic manufacturing and AI-compute economy.

The Eswatini supply gap
Eswatini's national peak demand runs at roughly 230–234 MW against approximately 71 MW of installed domestic capacity, including about 60 MW of hydro and 10 MW of solar. The balance is imported through the Southern African Power Pool [14]. A country importing the majority of its electricity is exposed to its neighbours' supply conditions, their tariffs, and their outages — and that exposure sets a ceiling on what can be built domestically.
Imported power is a constraint on industry
Manufacturing and data-center load require supply that is firm and priced predictably over a long horizon. Where a large share of supply is imported and subject to regional conditions, industrial investment is difficult to underwrite regardless of how attractive the labour or land economics look.
The demographic case
Youth unemployment is approximately 54% on World Bank / ILO-modelled 2024 data, with the IMF citing about 48.7% for 2023 [15]. Domestic generation does not close that gap by itself; the argument is that it is a prerequisite for the downstream industry that could.
The resource is already on the ground
Eswatini's existing irrigation canal network moves water continuously and was built for agriculture, not electricity. The flow is present, consistent, and unexploited for generation — stranded in the same sense as a gas well with no pipeline.
A sovereign-scale first phase
PowerLink's phase-one target is 100 MW of offtake, with a multi-stage power purchase agreement with the Eswatini Electricity Company in late-stage negotiation. The PPA is not executed, and no assurance exists that it will be executed or executed on the terms sought.
Canal hydro, and why it suits this site
This is not dam construction. In-canal generation places turbines in an existing engineered channel, taking energy from water that is already flowing to somewhere else for another reason. The design consequences run through the whole project.
Run-of-canal, not impoundment
There is no reservoir, no inundation, and no change to the water's destination — flow passes through the turbine and continues to its agricultural use. That removes the resettlement, sedimentation, and ecological questions that dominate conventional hydro development, and with them much of the permitting timeline.
Flow validated before hardware
Three canals have been profiled using acoustic Doppler current profiling, so the flow assumptions underpinning the design are measured rather than modelled. Measuring first is the difference between a standardized unit that fits its site and one that has to be re-engineered after delivery.
A standardized, drop-in turbine
Each unit is a single design intended to be installed without site-specific redesign. The first four turbines are staged in Phoenix and shipping to the first canal for field validation. Standardization is what converts each additional site from an engineering project into an installation.
Predictable output
Canal flow is managed for irrigation and is therefore steadier than run-of-river, which follows rainfall. Steadier input makes output easier to commit to under a PPA — though actual generation will depend on canal scheduling, seasonal water allocation, and operating availability.
What a canal turbine actually is
The unit is intentionally unremarkable. Every design decision trades peak efficiency for the ability to be built repeatedly, installed quickly, and maintained by a local crew — because at four units the engineering dominates, and at forty the logistics do.
Low head, moderate flow
A canal presents a very different resource to a dam: little vertical drop, but continuous and predictable volume. The machine is therefore sized around flow rather than head, which puts it in a class of turbine that is mechanically simpler and physically smaller than conventional hydro plant.
Installed into existing works
Units sit within a channel that already exists and already carries water to a defined destination. Civil work is limited to mounting, and there is no new impoundment, no diversion, and no change to downstream allocation — which is what keeps the environmental and consenting profile modest.
Serviceable in place
Long-term output on an asset like this is a maintenance question, not a design question. Units are intended to be inspected and serviced without dewatering the canal or specialist lifting equipment, so operations can be handled by trained local personnel rather than flown-in crews.
Interconnection at distribution voltage
Because each unit is small and sits near existing infrastructure, connection is intended at distribution rather than transmission voltage. Actual arrangements depend on the executed PPA and on the utility's technical requirements, neither of which is settled.
Solar and waste in the same loop
Canal hydro is the anchor, not the whole plan. The stated intent is to combine it with solar generation and with waste-stream conversion so the country's supply base broadens as each element is added, rather than concentrating on a single resource.
Complementary profiles
Solar peaks midday and disappears at night; canal flow is managed and steadier across the day. Paired, they cover more of a load curve than either does alone, which is what makes the combination worth engineering rather than simply co-locating.
Waste as a third input
PowerLink's digestion process is designed to take tire and plastic streams and produce recovered materials plus energy. Applied here, it addresses a domestic waste-handling problem and adds firm generation from the same facility — the same closed-loop pattern applied in a different jurisdiction.
Sequencing
Hydro comes first because the resource is measured, the hardware is built, and the counterparty conversation is advanced. Solar and waste follow as separate development decisions, each with its own financing, permitting, and offtake requirements, and none of them committed.
One development footprint
Site access, government relationships, permitting pathways, and logistics are largely shared across all three. Establishing them once for hydro is what makes the later additions incremental rather than starting over.
Beyond electricity: the downstream case
Generation is the enabling step, not the objective. The stated intent is that reliable, domestically produced baseload anchors manufacturing and AI-compute capacity inside the country, so that the value added from the power stays local rather than being exported as raw capacity. Waste streams and solar are intended to supplement canal hydro in the same closed-loop pattern PowerLink applies elsewhere, so the country's energy base broadens as each is added. This is a description of intent over a multi-year horizon. It depends on the PPA being executed, on financing, on the demonstration units performing as designed, and on conditions in a jurisdiction where PowerLink is an early-stage foreign developer. None of it is assured.
The next are deployment, not invention.
Each turbine is a standardized, drop-in design. The first four units enter field validation; once validated, scaling is replication, not R&D.
