TariffTally

TariffTally is a web app (with optional mobile companion) for energy market participants who need to understand what congestion, losses, and nodal vs hub spreads are doing to their costs and revenues. Users connect ISO/RTO public data feeds (and optionally their own settlement statements) to build a daily “cost attribution” view: how much of the bill/credit came from energy, congestion, losses, uplift, and ancillary services. The app flags abnormal drivers (e.g., a single constraint, a shift in DA/RT divergence, or a recurring uplift charge) and produces exportable reports for finance and risk teams. It’s not a trading terminal; it’s a post-trade and planning tool that reduces reconciliation time and helps teams justify hedges, contract terms, and siting decisions. Realistically, the value is in clean normalization of messy market data and repeatable reporting.
