Britwind

What Britwind does

Britwind Limited designs, manufactures, and supplies small-scale horizontal-axis wind turbines from 1kW to 15kW, alongside battery storage and hybrid inverter systems. Founded in 1999 as Iskra and later rebranded through Evance before its 2014 acquisition by Ecotricity, the company operates a production facility in Stroud, UK with in-house composites blade manufacturing. Core technology centres on direct-drive brushless permanent magnet generators — eliminating the gearbox and reducing wearing parts — together with two registered patents, Reactive Pitch™ and ElectroBrake™, which adjust blade angle and provide braking with no moving parts. The current product line consists of four turbines (H1, H5, H11, H15) plus 5.2kW and 9.5kW battery storage units; legacy Iskra AT5, Evance R9000, and Britwind R9000 units remain supported through spares and refurbishment services.

Revenue is generated primarily from one-time hardware sales of turbines and battery systems, supplemented by installation services and an aftermarket spares/refurbishment stream. Pricing on a per-unit basis ranges from £3,195 ex-VAT for the H1 controller-only package through £35,000–£40,000 fully installed for the H5 and up to £170,000–£190,000 fully installed for the H11/H15. Distribution combines direct-to-customer sales (website and contact centre) with a global network of approved resellers, service providers, and installers. Customers span four primary segments — residential, agricultural, commercial/business, and industrial/micro-grid — with over 2,500 installations recorded globally across the UK, Japan, and other markets. Certificated to UKAS ISO 9001 and Nippon Kaiji Kyokai standards, Britwind operates as a subsidiary within the Green Britain Group led by Dale Vince.

Core offering

Britwind designs, manufactures and sells small-scale horizontal axis wind turbines (1kW to 15kW: H1, H5, H11 and H15 models) for residential, agricultural, commercial and off-grid/microgrid customers seeking on-site renewable generation. The portfolio is supported by battery storage systems (5.2kW and 9.5kW options), a full installation service, and a spares/refurbishment offering for the installed base. Design and manufacturing, including blade production, are carried out in the UK at the Stroud facility.

Product overview

Britwind offers a portfolio of small-scale wind turbines ranging from 1kW to 15kW, designed and manufactured in the UK. The current product lineup consists of four core horizontal-axis wind turbines: the H1 (1kW) for domestic micro-generation, the H5 (5kW) as the flagship market-leading model, the H11 (11kW) optimized for lower wind speed sites, and the H15 (15kW) for high-wind locations. All turbines feature direct-drive brushless permanent magnet generators with no gearbox, patented control systems (Reactive Pitch and ElectroBrake), and are designed for 20+ year operational life with minimal maintenance. The portfolio is complemented by battery storage solutions (5.2kW and 9.5kW options) that enable energy storage for use during peak hours or when generation is low. Legacy products including the Iskra AT5 and Evance R9000 remain supported with spare parts and service. With over 2,500 installations globally across homes, farms, and businesses, Britwind's turbines can be deployed as grid-tied or off-grid systems, often paired with solar PV for hybrid renewable solutions.

• Eocycle: Canadian manufacturer of distributed wind turbines in the 10–25kW range with direct-drive permanent-magnet generators targeting commercial and agricultural customers. Closely comparable technology stack and go-to-market focus to Britwind's H11/H15 line.
• Vergnet: French manufacturer known for medium and small wind turbines (including 6m and 12m blades, 10kW–275kW) and hybrid solar-wind systems for islands and remote grids. Overlaps with Britwind on micro-grid/off-grid use cases and European customer base.
• XZERES Wind: US small-wind turbine OEM offering 2.5kW–10kW units for residential, agricultural, and remote applications with global dealer distribution. Direct competitor in the same small-wind segment with similar hardware-sales revenue model.
• Aeolos Wind Turbine: Chinese manufacturer of small horizontal axis wind turbines (1kW–50kW) exported globally for residential and commercial use. Competes with Britwind on price in the small-wind segment, particularly in emerging markets.
• Gaia-Wind: Scottish manufacturer of 11kW and 20kW small wind turbines for farms and commercial sites. Closely comparable UK/European small-wind competitor targeting the same agricultural and rural customer segments as Britwind.
• Northern Power Systems: Manufacturer of small to mid-size wind turbines (including the legacy 60kW and 100kW platforms) with permanent-magnet direct-drive generators. Overlaps directly with Britwind on technology architecture and distributed wind customer base.
• Wind Energy Solutions (WES): Dutch manufacturer of small to medium wind turbines (5kW–250kW) including the Tulip and earlier 5kW/10kW platforms sold across Europe. Comparable European small-wind OEM competing for similar agricultural and commercial customer base.

Broad incumbents

• Vestas: World's largest wind turbine OEM (utility-scale 2MW–15MW platforms). Not a direct small-wind competitor but a broad incumbent in the wind energy category whose technology and cost trends shape the entire industry's supply chain and customer expectations.

Emerging players

• Tesla Energy: Adjacent competitor in distributed home energy via Powerwall battery storage and solar roof offerings. Increasingly bundled with solar as the default 'home energy independence' solution, displacing small-wind value proposition at the residential level.
