What Sonaura does
Sonaura Limited is a privately-held UK renewable energy company, founded in 2024 and headquartered in London, that develops private wire solar, wind, and battery storage projects for large industrial power users across the UK and Germany. Its core technology consists of bespoke private wire systems that deliver electricity via dedicated underground cabling connected behind the customer's import meter, completely bypassing the public grid and the associated network charges and taxes that typically represent up to 60% of industrial electricity costs. The company operates from offices in London and Berlin, with a German entity trading as Sonaura Energy.
Sonaura offers two primary commercial models: the Private Wire Power Purchase Agreement (PWPPA), under which Sonaura funds 100% of development, construction, and operations, retains asset ownership, and sells power under long-term 15-40 year fixed-price contracts; and the Development Services Agreement (DSA), where the customer funds development and retains ownership in exchange for a per-MW development fee. Supporting revenue comes from index-linked land lease payments to landowners (typically £1,000/acre in the UK and €1,000-€2,000/acre in mainland Europe, annual, over 30-40 years). Go-to-market is exclusively direct enterprise sales via a client solutions team split across London and Berlin, with target customers being industrial power users in verticals such as automotive manufacturing and consumer packaging.
The company is wholly backed by Eurazeo, a European investment group with over €35bn in assets under management that has invested twice since 2024 and is supporting preparation for a larger Q3 2026 construction-funding round. As of mid-2026, Sonaura had signed PPAs with Bentley Motors (7 MW solar project for Crewe HQ) and Albéa (4.2 MWp solar for the Scheßlitz, Germany factory), and disclosed a project pipeline that had grown from 1 GWp to over 3 GWp.

Revenue model
- Private Wire Power Purchase Agreement (PWPPA): Sonaura funds 100% of project development, design, build, installation, operation and maintenance. Retains ownership of the project and sells power generated to power users under long-term private wire PPA. Power users pay for electricity supplied with no upfront capital investment required.
- Development Services Agreement (DSA): Power user funds 100% of development costs until project reaches 'ready to build status'. Power user retains ownership of project and pays Sonaura a development fee based on total installed capacity upon milestone achievement.
- Land Lease Payments: Index-linked competitive rents from £1,000/acre in UK to €1,000-€2,000/acre in mainland Europe for land used for renewable energy projects over 30-40 year lease terms

Sonaura product offering
Product offeringCore offering
Sonaura designs, funds, builds, owns and operates private wire renewable energy systems (solar PV, onshore wind, and battery storage) that supply electricity directly to industrial customers via dedicated underground cabling, bypassing the public grid. The company sells power to industrial users under long-term Private Wire Power Purchase Agreements (PWPPA), typically 15–40 years, or delivers projects under Development Services Agreements (DSA) where the customer funds and owns the asset. Each project is bespoke, technology-agnostic, and tailored to the customer's site, demand profile and credit profile.
Product overview
Sonaura is a renewable energy company specializing in off-site private wire renewable energy solutions for industrial power users across Europe. The company offers two primary commercial models: the Private Wire Power Purchase Agreement (PWPPA), where Sonaura funds, owns, and operates the renewable project, and the Development Services Agreement (DSA), where the power user funds development and retains ownership. The core technology portfolio includes solar PV, wind, and battery storage projects that are connected via private wire directly to industrial facilities, bypassing the grid. Projects are delivered through a five-stage process: site assessment, commercial and technical proposal, site development, construction and commissioning, and long-term operation. Sonaura also provides land lease services for landowners, managing the entire project lifecycle from land assessment through decommissioning. The company is backed by Eurazeo and operates offices in London and Berlin.

Products and services
- Private Wire Power Purchase Agreement (PWPPA) A fully funded commercial model in which Sonaura funds 100% of project development, design, build, installation, operation and maintenance. Sonaura retains ownership of the renewable asset and sells the electricity generated directly to the power user under a long-term private wire PPA (15–40 years), with no upfront capital required from the customer. Intended for large industrial power users across the UK and Germany seeking predictable renewable energy supply.
- Development Services Agreement (DSA) Alternative commercial structure where the power user funds 100% of development costs until the project reaches 'ready to build' status. The power user retains ownership of the project and pays Sonaura a development fee based on total installed capacity (MW) upon milestone achievement. For industrial customers who want to own their private wire renewable asset while outsourcing development expertise.
- Private Wire Solar PV Projects Bespoke private wire solar photovoltaic projects that generate renewable electricity and supply it directly to a business's site via a dedicated cable behind the import meter, bypassing the public grid. A solar-only solution typically supplies 20–30% of a site's annual power demand. For industrial power users with available adjacent land suitable for solar generation.
- Onshore Wind Power Projects Onshore wind power projects deployed via private wire, typically used when the power user has 24/7 demand and the site profile suits wind generation. Wind offers a flatter generation profile than solar, with higher output in winter and at night. Combined with solar, it supports balanced near 24/7 generation for industrial demand patterns.
- Battery Energy Storage Projects Behind-the-meter energy storage systems integrated into private wire solutions, designed in consultation with power users to optimise generation and consumption profiles, manage excess renewable generation, and respond to variable industrial demand. Used in combination with solar PV, wind or both to firm up supply.
- Land Lease Services for Renewable Projects Land acquisition and lease services for landowners wanting to host private wire renewable energy projects. Includes site assessment, option agreements, development management, ongoing lease payments (£1,000/acre UK; €1,000–€2,000/acre mainland Europe, index-linked) and decommissioning at lease end. Enables continued agricultural use alongside biodiversity enhancements. For agricultural landowners with 10+ acres of suitably located, flat land near industrial demand.
