Company profile

researched Aug 2026

Omnidian is a Seattle-based provider of performance assurance for solar photovoltaic and battery energy storage assets. Its service combines remote monitoring and data analytics with coordinated field service, aiming to keep installed clean energy systems producing at expected levels after installation. The core offering is packaged as a single service line, "Performance Assurance," with configurable options for different owner types.

The offering includes a production guarantee under which Omnidian covers the shortfall if a system generates less than 95% of the company's projected energy forecast; live dashboards that convert technical KPIs into operational reporting; investor-oriented reporting intended for finance teams and investment partners; predictive, AI-driven alerting intended to flag underperformance before it results in losses; and dispatch of local technicians for corrective and preventive work. The company states it manages more than 2 gigawatts across more than 2,000 sites and serves clients in 48 states, Washington, D.C., and Puerto Rico.

Business model

Omnidian sells an ongoing performance assurance service covering monitoring, analytics, reporting and coordinated field maintenance for solar and storage portfolios, positioned as a single-source, end-to-end provider for asset owners. The service includes a contractual energy production guarantee in which Omnidian absorbs shortfalls below 95% of its forecast.

Traction

The company reports managing over 2 gigawatts across more than 2,000 sites for more than 250 clients, driving over $6 million per year in avoided operations and maintenance costs. Published case studies cite a 14% increase in average monthly performance index for a commercial solar developer within six months, and a 60% reduction in corrective maintenance in a commercial portfolio analysis, associated with reducing truck rolls from an industry average of 6.06 per MW to 2.37.
