Cleanwatts

Corridor footprint

Cleanwatts is a Lisbon-headquartered climate-tech company focused on decentralised energy communities — bringing solar PV generation, energy management, and virtual energy-sharing to communities of consumers under Portugal’s Comunidades de Energia Renovável framework. The company runs around 70 energy communities under approval and in operation in Portugal, with combined photovoltaic capacity of approximately 30 MWp.

Cleanwatts has two distinct Nordic anchors. First, on the capital side, Oslo-based Nordic growth investor Verdane partnered with the company in 2022 (with an initial €25M round) and built it into a scaled platform before realising the investment to DWS in February 2026 in a deal that includes a €150 million investment commitment through 2030. Second, on the deployment side, Cleanwatts is a named technology partner inside Brobyholm, the flagship Swedish smart-energy community near Stockholm developed by S Property Group with ABB, Samsung, OBOS, SMA and Three Sweden — where Cleanwatts’ virtual energy-sharing platform handles the resident-level energy logic.

Why this matters for the corridor

Cleanwatts is one of the cleanest examples of a Portuguese climate-tech business operating credibly inside a Nordic ecosystem. The Verdane-to-DWS exit demonstrated that Nordic growth capital can build an Iberian platform to institutional scale. The Brobyholm partnership demonstrates the reverse direction: Portuguese energy-management software embedded inside a Swedish flagship development. Both vectors matter for understanding how the Portugal ↔ Scandinavia corridor compounds in distributed energy.
