Who we are

Eden Geothermal Ltd has been set up by three partners: Eden Project, EGS Energy Ltd, and Bestec (UK) Ltd to unlock the geothermal energy deep in the granite beneath Cornwall. We have secured funding to drill a 4.5km deep well at the Eden Project, and heat its famous Biomes, greenhouses and offices.

This is the first phase of a two well development. It will pave the way for the second phase: another 4.5km well and an electricity plant.

Main Board

Augusta Grand, Executive Director

Before leading Eden Geothermal, Gus was Head of Policy at Eden, developing Eden’s sustainability and science programme. This involved a wide variety of educational exhibits such as the Wellcome Trust Funded Invisible Worlds programme, partnership projects and research as well as keeping an eye on Eden’s own emissions.  The ambition to generate Eden’s own renewable heat and power has been a cornerstone of strategy for more than a decade, and Gus has been working on the geothermal project since 2012. She has been at Eden since 2001 and has created content and policy in many subject areas: biodiversity, sustainability, development, climate, energy, transport and mining. She specialises in partnership projects with industry, academia and the public sector.
