Cleanwatts





Cleanwatts is a Portuguese climate technology company that develops, finances, and operates solar-powered Energy Communities, enabling local production, sharing, and management of clean energy with zero upfront investment. A pioneer in Portugal, the company launched the country's first renewable energy community in Miranda do Douro in 2021.
Cleanwatts is a climate technology company headquartered in Coimbra, Portugal, with a mission to bring the energy transition to where it matters most: locally. The company specialises in developing distributed solar energy projects and renewable Energy Communities, offering organisations and consumers a path to clean, affordable electricity without any upfront capital expenditure.
Through its turnkey model, Cleanwatts invests in, installs, and operates solar power plants at clients' facilities. Organisations benefit from competitively priced, predictable renewable energy over the long term, while surplus electricity is shared within a local Energy Community — creating economic, environmental, and social value for nearby businesses, institutions, and households.
A pioneer in this model in Portugal, Cleanwatts created the country's first renewable Energy Community in Miranda do Douro in August 2021. Since then, it has expanded its network of communities across Portugal, combining proprietary digital technology, financial capital, and operational expertise to manage every aspect of energy community development.
Cleanwatts also offers intelligent energy management systems that optimise consumption and sharing within each community, improving energy security and contributing to the decarbonisation of local economies. The company actively works with both producers — who generate clean solar electricity — and consumers who wish to access renewable energy at competitive rates.
With a growing team and investor backing, including from DWS Infrastructure, Cleanwatts is scaling its model internationally through its Cleanwatts Digital platform, positioning itself as the operating system of choice for the creation and management of renewable energy communities worldwide.
Our Goal
Cleanwatts aims to decentralize, digitize, and democratize access to clean energy by developing and operating renewable Energy Communities across Portugal and beyond.
Our Wishes
Cleanwatts seeks energy producers and consumers interested in joining or creating Energy Communities, as well as partners and investors committed to accelerating the local energy transition.
