Documented cause
Natel Energy, a Alameda-based fish-safe hydropower turbine company backed by Breakthrough Energy Ventures and others with over $35M raised, shut down in mid-2023. Despite demonstrating its Restoration Hydro Turbine at sites in Oregon and Europe and receiving positive regulatory assessments, the company could not build a pipeline of projects large enough to sustain operations. Small hydropower permitting in the US takes 7-10 years, making project payback cycles incompatible with venture timelines.
Lesson
“Infrastructure with 7-10 year permitting cycles is structurally incompatible with venture capital; seek patient capital structures instead.”
