Deutsche Telekom explores using surplus renewable energy to power Bitcoin mining

Deutsche Telekom began exploring options to use surplus renewable energy to power Bitcoin mining, a move it stated would bring Germany in line with the US and Finland

Deutsche Telekom has started exploring the use of surplus renewable energy to power Bitcoin mining in a bid to help stabilise Germany's electricity sector.

The operator will pilot a Bitcoin mining project with private bank Bankhaus Metzler through its T-Systems Multimedia Solutions (MMS) subsidiary, gathering data and insights into how leftover renewable energy can be employed in the crypto-currency process.

The peaks and troughs of weather-dependent renewable energy are creating a need to balance grids, particularly in the solar and wind sectors, Deutsche Telekom noted.

The US and Finland are particularly advanced in using such techniques, it added, noting that the "flexible load" of the Bitcoin mining segment lends itself well to the power-project's goals.

The aim is to use the data created in the pilot to help stabilise power grids, which Deutsche Telekom predicted could benefit wind- and solar-power generating companies.

Deutsche Telekom has lined up Metis Solutions to manage the Bitcoin mining project, the containers for which are located in a solar-powered site operated by façade-maker Riva Engineering.

"The excess energy is converted into digital values through the miners," explained Oliver Nyderle, head of Digital Trust and Web3 Infrastructure at T-Systems MMS. "We call this digital monetary photosynthesis."

T-Systems MMS is managing the devices used and Bankhaus Metzler is eyeing the opportunities for broader financial services offered by digital assets.

The bank established a digital assets unit in 2022, focused solely on blockchain technology. Deutsche Telekom noted that it has operated a Bitcoin node as part of a broader Web3 strategy since 2023, which the energy trial expands.

"Blockchain technology is gaining increasing importance in operational business outside the financial industry," said Hendrik Konig, head of digital assets at Bankhaus Metzler, arguing the case for working with trustworthy partners on such schemes.
