HelioWave
Project Overview
HelioWave pairs floating solar on a disused reservoir with shoreline storage, supplying a coastal desalination and water treatment facility that had been running on imported grid power.
What we provide:
- Floating array design and anchoring
- Water quality and ecology assessment
- Storage sizing for process load
- Private wire design
- Marine and environmental permitting
- Operations and access planning



Our Approach
Our platform and services are designed to make eco-conscious transformation simple, scalable, and transparent.
Anchoring was the governing constraint: the reservoir has a variable draw-down of nearly four metres, so the mooring system had to accommodate the range without loading the bank. Ecological survey drove the coverage limit, which was set at 45% of surface area to preserve light penetration and oxygenation.

Technology Used
HelioWave supplies the majority of the treatment facility's annual demand behind a private wire, and the array's operating temperature benefits measurably from the water beneath it.
- 34 MW floating generation with 40 MWh shoreline storage
- 68% of facility demand supplied behind the meter
- Surface coverage capped at 45% on ecological advice
- Reduced reservoir evaporation across the covered area
