Deutsche Energie-Agentur GmbH, known as dena, is Germany’s national energy agency and a federally owned company focused on energy transition and climate policy implementation. Based in Berlin, dena works with partners from the public and private sectors to support the shift toward efficient, intelligent and sustainable energy systems. Its remit is broad: it advises on policy, develops studies and data tools, supports market actors, and runs programmes that connect government, business, research and civil society.
The agency’s work spans Germany and extends internationally. It is active in buildings, heating, electricity, industry, mobility and energy infrastructure, with a strong emphasis on decarbonisation and practical implementation. One of its visible areas of activity is the building sector, where dena publishes reports and analyses on renovation, heating systems, green gases and energy prices. Its recent work on the Gebäudemodernisierungsgesetz, for example, examines how regulation affects investment decisions in heating technologies and the role of biomethane, electrification and biogenic fuels over the coming decades.
dena also runs and supports several specialist platforms. These include the Gebäudeforum klimaneutral, which provides quality-assured information on climate-neutral construction and refurbishment, and the Energie-Effizienz-Experten directory, a register of qualified professionals for energy-efficient building and industrial projects. Another significant initiative is the SET Hub, which supports clean-tech start-ups and innovation in the energy sector.
The organisation says it employs around 700 experts from about 30 countries. Its leadership is headed by the management of dena; the company is chaired in its governance structure by public-sector representatives as a federal enterprise. Publicly available material on the website does not identify a single founding year in the excerpt provided, but dena describes itself as a long-established institution and marks 20 years of the dena Energy Award in 2026.
