Germany's coal phase-out (2020)
The German parliament passed the Coal Phase-Out Act, setting a hard deadline of 2038 for ending coal-fired power generation, with earlier closure targets for specific plants. Berlin's local coal plants, including the Marzahn site's neighbors, face closure under this timeline.
Utilities and cities began planning replacements for coal-fired district heating.
The phase-out created the demand Berlin's geothermal program now aims to fill.
The Marzahn exploration site is on a power plant campus whose coal-fired heat production must be replaced by 2038 at the latest — the deadline concentrating Berlin's mind on geothermal now.
