Winse Power Oy: Finland’s Light-Based Energy Solutions for European Strategic Autonomy

Winse Power Oy is a Finnish deep-tech venture engineering a new frontier in energy delivery: using light to transmit power. Founded in 2023 in Tampere, Finland, this emerging company develops “power-by-light” solutions that convert laser light into electricity, enabling safe, wireless power links for demanding environments. By manufacturing its own optoelectronic semiconductor chips domestically, Winse Power is carving out a niche at the intersection of clean energy and defense technology. Its innovations – from fiber-optic power cables that work in ultra-high voltage grids to photovoltaic devices that harvest ambient light for battery-free sensors – address critical needs in Europe’s quest for technological sovereignty and resilient infrastructure.

The company’s participation in elite programs like the European Space Agency’s Business Incubation Centre and NATO’s DIANA accelerator underscores the strategic value of its technology on both sides of the Atlantic. Winse Power’s quiet revolution in energy transmission exemplifies how a small European startup can tackle big strategic challenges: reducing dependence on foreign suppliers, “hardening” military power systems against disruption, and contributing to a greener, self-reliant future. It’s a story of photonics and innovation, with implications stretching from the Arctic grid to orbital satellites – and it is only just beginning. Organization & Sector: Winse Power Oy is a deep-tech startup spun off from Tampere University research in Finland, focused on optoelectronic power and data links.

It straddles the defense and energy domains as a dual-use technology provider, integrating semiconductor, photonics, and clean energy expertise. The company aligns with Europe’s Emerging Disruptive Technology priorities in Critical Technologies (semiconductors & alternative energy) and Directed Energy systems, given its specialization in laser-based power transmission and high-efficiency photovoltaic converters. Strategic Autonomy Contribution: Winse Power directly bolsters European technological sovereignty by designing and fabricating its own optical power chips in Finland, reducing reliance on extra-EU suppliers.
