TERRASPARK

Core business

TerraSpark is developing space-based solar power (SBSP) using a modular, step-by-step approach: capture solar energy in orbit and transmit it to Earth by radio frequency, delivering electricity that is continuously available, weather-independent and cable-free.

Rather than starting with large orbital systems, the company commercialises radio-frequency wireless power transmission on Earth first.

Products and services

TerraSpark sells one capability, wireless power transfer over radiofrequency, packaged four ways as it scales from Earth to orbit. Today we deliver terrestrial WPT as a service, beaming power to sites cables and fuel can't reach, and from orbit we sell firm clean power: premium delivery from LEO at €0.30/kWh, then grid-scale power purchase agreements from MEO and beyond falling to €0.03/kWh. For partners who want more than supply, we also offer the constellation itself as an owned energy asset.

Technical means

• Radio-frequency power beaming: a steerable, safe beam transmits captured solar energy to a ground receiver. Rectenna ground segment: converts incoming radio waves back into usable electricity.
• Modular SBSP architecture: enabled by falling launch costs and advances in satellite manufacturing and orbital robotics, which the company cites as what makes a 1970s concept viable today.
• Validation targets: alignment accuracy, energy density, atmospheric tolerance.

Main customers

Off-grid and remote mining, ports and remote industry that can't get reliable power today, plus the utilities, cities and energy majors buying or owning firm clean supply at grid scale.

Major space projects

Phase 1 (2026): wireless power transmission over controlled distances on Earth, including a live event.

Phase 2 (2027-2028): orbital technology demonstrator in 2027, then first space-to-Earth power transmission from a satellite prototype in 2028.

Phase 3 (2030): full-scale commercial constellation.
