DWS will invest €150 million through 2030 to expand Cleanwatts’ renewable energy communities across Portugal.
The model enables shared solar generation with no upfront cost, cutting electricity expenses by 20 to 40 percent for commercial users.
Portugal’s regulatory framework for energy communities is emerging as a template for decentralized power systems across Europe.
A Strategic Bet on Distributed Energy
DWS, the asset management arm of Deutsche Bank, has acquired Portuguese renewable energy community platform Cleanwatts in a transaction backed by a €150 million investment commitment through 2030. The deal transfers ownership from Nordic private equity firm Verdane and positions Portugal at the forefront of Europe’s shift toward decentralized energy systems.
The acquisition will be executed through a DWS managed infrastructure fund and aims to accelerate the rollout of Comunidades de Energia Renovável, Portugal’s renewable energy communities that enable multiple users to share locally generated electricity. The investment aligns with the country’s Plano Nacional de Energia e Clima, which sets out the pathway to carbon neutrality by 2050 through rapid expansion of distributed renewable generation.
Miguel Horta e Costa, Partner at DWS, said Portugal’s regulatory framework for renewable energy communities is among the most advanced in Europe and can serve as a model for other markets.
A Platform Built Around Shared Solar
Founded in Coimbra, Cleanwatts has developed a digital platform that manages solar generation, storage, and energy sharing among commercial and residential users within defined local networks.
The model centers on “anchor clients” such as office buildings, logistics hubs, factories, and shopping centers. These large energy consumers install solar photovoltaic systems with no upfront capital outlay and purchase electricity at predictable rates below market prices.
Surplus electricity is redistributed to surrounding communities at reduced tariffs, creating local energy ecosystems that lower costs and emissions while improving access to clean power.
Pedro Antão Alves, CEO of Cleanwatts, said “the company’s engineering and monitoring systems continuously analyze weather patterns, consumption trends, and grid conditions to maximize efficiency and savings.“
Real Estate and Infrastructure Implications
The expansion of renewable energy communities has direct implications for commercial real estate and infrastructure investment across Portugal.
Energy efficient buildings equipped with renewable energy systems increasingly command premium valuations and attract tenants seeking cost predictability and sustainability credentials. Market analyses indicate energy efficient office buildings in Lisbon can achieve rental premiums of 8 to 12 percent and experience lower vacancy rates.
By eliminating upfront solar installation costs and locking in long term electricity pricing, the Cleanwatts model helps property owners reduce operating expenses and improve net operating income. Projected electricity savings of 20 to 40 percent translate into measurable gains in asset value and capitalization rates.

Policy Alignment and European Relevance
Portugal already generates more than 60 percent of its electricity from renewable sources and aims to reach 80 percent renewable electricity by 2030. Strong solar irradiation, advanced grid modernization, and clear regulatory frameworks have created favorable conditions for distributed energy expansion.
With more than 300 sunny days annually in southern regions, Portugal offers solar generation potential significantly higher than much of Central Europe. Combined with smart meter deployment and grid modernization supported by EU funding, the country is well positioned to manage high levels of distributed generation.
DWS noted that Portugal’s regulatory sophistication, including provisions for energy communities and self consumption, provides policy certainty that supports long term infrastructure investment.
Investment Signals for the Iberian Market
The acquisition highlights growing investor interest in decentralized energy infrastructure and its integration with sustainable real estate.
For institutional investors, renewable energy communities offer predictable revenue streams, reduced energy risk exposure, and enhanced ESG performance. For property developers and owners, participation can future proof assets against rising energy costs and tightening building efficiency standards.
The transaction also signals potential export opportunities. As EU member states accelerate renewable deployment to meet climate targets, Portuguese expertise in community energy systems may expand into other markets.
A Distributed Energy Future
DWS’s investment marks a significant step in Europe’s transition toward localized, shared energy systems. By combining regulatory clarity, advanced technology, and strong solar resources, Portugal is emerging as a test case for decentralized power models that align climate goals with economic value.
As energy costs, tenant expectations, and regulatory pressures evolve, distributed renewable infrastructure is moving from niche innovation to core investment strategy across Europe’s built environment.
