Victor Romero, Delve Underground CEO, stated "Sustainable hydropower is not just a cornerstone of our clean energy future; it's a testament to our commitment to harmonizing human progress with environmental stewardship. At Delve Underground, we believe in harnessing the power of water responsibly to create lasting, positive impacts on communities and ecosystems.

Delve Underground’s membership in the IHA underscores its dedication to advancing the field of hydropower.
