Energy efficiency in data centres<\/h1>\n \n <\/div>\n \n
\n

Section 4 of the German Energy Efficiency Act (EnEfG) requires data centres to meet strict standards for energy efficiency (PUE values) and waste heat utilisation. Binding requirements also apply to the use of electricity from renewable sources, to certifications and energy management systems, and to a staggered obligation to reuse energy.<\/p>\n <\/div>\n \n \n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n<\/div>\n\n\n

    (1) Data centres that commence or have commenced operation before 1 July 2026 must be constructed and operated in such a way that, from 1 July 2027, they permanently achieve a power usage effectiveness of less than or equal to 1.5 and, from 1 July 2030, a power usage effectiveness of less than or equal to 1.3 on an annual average.<\/p>\n

    (2) Data centres that commence operation on or after 1 July 2026 must be constructed and operated in such a way that they achieve a power usage effectiveness of less than or equal to 1.2 and a share of reused energy of at least 10 per cent; at least 15 per cent from 1 July 2027 and at least 20 per cent from 1 July 2028.<\/p>\n

    (5) Operators of data centres must cover 50 per cent of their electricity consumption from renewable energy sources on a balance-sheet basis from 1 January 2024, and 100 per cent from 1 January 2027.<\/p>\n <\/div>\n <\/div>\n <\/details>\n
