Sitara provides forward retail electricity rate forecasts for distributed solar project finance, breaking down utility tariffs into generation, capacity, transmission & distribution, and rider components so every underwriting assumption remains visible and auditable. Its RateBook™ platform continuously monitors tariff filings and embeds ISO/RTO market signals to deliver utility‑specific forecasts, while the Atlas™ tool adds infrastructure siting analytics for large‑load and data‑center projects. The service is used by community solar developers, IPPs, and project finance teams across multiple U.S. jurisdictions.

Problem
Project finance and acquisition teams for distributed solar need accurate, transparent forecasts of future retail electricity rates, but utility tariffs are complex and frequently updated, making assumptions difficult to audit and increasing risk in underwriting and diligence.
Solution
Sitara’s RateBook™ platform generates forward retail electricity rate forecasts at the tariff level for U.S. utilities. The service decomposes each tariff into generation, capacity, transmission & distribution, and rider components, preserving visibility into every cost element used in financial models. Forecasts are continuously refreshed as utilities file new rate cases, and ISO/RTO market signals are integrated to reflect wholesale price trends. The resulting data set supports underwriting, tax‑equity structuring, and acquisition diligence with auditable assumptions across multiple jurisdictions. Users access the forecasts through a subscription‑based interface that provides historical rates, component‑level breakdowns, and scenario analysis tools.
Target Audience
Primary customers are distributed solar developers, independent power producers, and project finance teams, as well as renewable asset owners and infrastructure funds conducting acquisition or re‑contracting diligence.
