Peter Grassberger, BSc

I'm a software developer and co-owner of Voltana, where we do software, administration and marketing for energy communities.

With EG Austria I advocate for more renewable energy, fair compensation and energy independence.

Politically I campaign for digital sovereignty: I'm active with the Piraten Graz and running with them in the 2026 Graz city council election.

And at Spektral I helped keep the place alive and in community hands in 2025 through a crowdlending campaign.
