Energie-Museum Berlin, Technology museum in Lankwitz, Berlin, Germany.

Energie-Museum Berlin is housed in the 1984 battery storage building on the former Steglitz power station site at Teltowkanalstraße 9 in Lankwitz. The three-storey concrete-and-brick structure with a flat roof, designed by Clemens Mletzko, stands out against Hans Heinrich Müller's older power station buildings with their dark brown Rathenow hand-struck brick facades. Inside, around 1,800 m² over four floors displays power station technology, the electricity grid, public lighting, protection and measurement technology, occupational safety, household appliances and communication technology.

The Steglitz municipality built its own power station here between 1910 and 1911 to plans by Hans Heinrich Müller; it opened on 15 March 1911 and was extended several times. The site also housed a Steglitz tram depot, whose carriage hall no longer stands. In 1984 the plant became a battery storage facility for West Berlin's island grid, shut down at the end of 1994, and since 2001 the building has held the volunteer-run museum.

Former employees of the power company run this place and share how energy systems shaped Berlin's daily life over the decades. Visitors learn about the technological choices that allowed the city to grow and function.

Visits are only possible by prior appointment, since the museum is run by volunteers; arrange a time in advance. Once inside, visitors can explore the roughly 1,800 m² over four floors with a printed guide or join a guided tour led by knowledgeable members. Admission and tours are free.

The battery storage building was designed by architect Clemens Mletzko in 1984 as a concrete-and-brick composite with a flat roof, three storeys and a basement. Its form stands out against the older power station and administration buildings by Hans Heinrich Müller, whose facades are clad in dark brown Rathenow hand-struck bricks with red and white brick ornament.
