TESTIMONIALS

RAG CEO Markus Mitteregger

Markus Mitteregger
CEO, RAG Austria AG

“The HOT Energy Group has substantially assisted RAG in planning almost all of our underground gas storage (UGS) facilities. The quality of their subsurface models has proved outstanding and has helped us to develop more than 50% of our gas fields into successful UGS operations and to become one of Europe’s leading gas storage operators.”
