KOEnergy is the flagship vertical-axis wind turbine range from KOVentures Ltd — quietly delivering reliable, low-maintenance clean power to homes, estates, schools, and infrastructure across the United Kingdom.
KOVentures Ltd is a UK-based provider of advanced renewable energy systems, specialising in high-performance vertical axis wind turbines (VAWTs) engineered for the United Kingdom's diverse and often turbulent wind environment.
The KOEnergy range is built on European engineering principles, incorporating high-quality materials, robust mechanical design and performance characteristics validated across global wind conditions — particularly suited to the UK's inland and semi-urban wind profiles.
Operates independently of wind direction — no yaw mechanism required.
Starts generating from approximately 1–2 m/s wind speed.
Low-vibration design ideal for urban and residential sites.
Survival wind speeds up to 40–50 m/s with reinforced construction.
Operating range from –40°C to +70°C across all UK conditions.
Simple mechanical design with no friction devices or overhauls.
On-grid, off-grid and hybrid configurations — SEG-ready.
Aluminium-alloy blades, fully recyclable lifecycle.
Two product families spanning 100W to 50kW — every configuration uses the same H-type vertical-axis architecture with a permanent magnet generator.

Direct grid-tie configuration with two-directional smart metering. Surplus energy is exported under the Smart Export Guarantee — the lowest-cost route to renewable generation.
Complete autonomy from the national grid. Battery storage captures every kilowatt-hour generated — ideal for rural, recreational and remote infrastructure.
The best of both worlds. Hybrid inverter intelligently routes power between batteries, grid and load — supports peak-shaving and load-shifting for public-sector buildings.
Manufactured from high-strength concrete poured into rotating conical moulds. Long service life, corrosion-resistant, and the most cost-effective option at height.
Combined thin-wall tubes with cable stays anchored to concrete blocks. Lightweight and transportable — disassembles into short sections for easy installation.
Lattice structure with wide leg span and vibration-damping connectors. Designed to sit no higher than three metres above the roofline.
Typical annual energy yield and CO₂ savings for a 5kW KOEnergy turbine at 15m hub height.
