Hidden Hollow Energy is a renewable electricity plant in Boise, Idaho. The plant converts biomethane into 3.2 megawatts of renewable power delivered to Boise’s local grid. This project promotes sustainability, pollution prevention, and the beneficial reuse of resources in Idaho’s capital region.
Before our ownership through our LFG Development (LFGDev) affiliate, the Hidden Hollow plant operated at under an 80% annual capacity factor. Today, it exceeds a 95% renewable electricity capacity factor. We believe in maximizing environmental benefits and sustainable impact—and we demonstrate it in real-world operations.
