About NEOWATT Ltd

NEOWATT Ltd is a Scottish startup developing power delivery infrastructure for the space industry. The company is focused on creating a space power grid that utilizes lasers to transmit power between spacecraft on demand. This technology addresses the limitation of fixed onboard power systems, transforming power into a flexible operational resource for the growing orbital economy.

The core of NEOWATT's offering is a specialized laser transmitter and receiver system designed to distribute power over tens of kilometers between assets in orbit. This capability allows spacecraft to sell surplus energy or draw additional power when needed for high-demand operations such as in-orbit servicing, manufacturing, or data processing. The system is also designed to provide continuous power during periods when solar generation is unavailable, such as during an eclipse or the two-week lunar night.

The market for space-based power is expanding, driven by the growth of satellite mega-constellations, in-orbit data centers, and plans for sustained lunar operations. The global space power supply market was estimated at USD 3.3 billion in 2024 and is projected to grow to USD 7.3 billion by 2034. NEOWATT's business model targets satellite operators, defense entities, and companies involved in lunar infrastructure and in-space industries. By enabling power to be treated as a tradable commodity, the company aims to reduce operational costs (OPEX) and capital expenditures (CAPEX) for its clients, extend satellite lifetimes, and reduce collision risks by potentially simplifying satellite design.

According to its roadmap, NEOWATT completed its concept validation and initial research, incubated through the UK Space Agency, in 2025. The company plans to develop a terrestrial demonstrator in 2026, followed by a full-power terrestrial version in 2027. An orbital demonstration is scheduled for 2028, with the goal of having a full operational space system by 2030 to serve a range of high-power orbital and lunar missions.
