How One Clean Energy Buyer Recovered $500K in PPA Overcharges—and Gained Confidence in Their Portfolio
With Verse’s help, this enterprise energy team moved from reactive guesswork to proactive invoice validation—uncovering hundreds of thousands in errors and strengthening developer relationships in the process.
The Problem
Are we overpaying—and is our project underperforming?
That’s the question this enterprise energy manager kept asking. The organization had entered into a virtual power purchase agreement (vPPA) with the promise of long-term savings and clean energy claims. But every month, a new invoice arrived with little transparency—and generation was consistently lower than expected.
The team didn’t have the bandwidth or in-house tools to verify the accuracy of their PPA payments, and they lacked insight into why their asset’s performance was trailing forecasts. With limited data access and no easy way to validate the numbers, frustration was building.
The Verse Solution
Aria’s Portfolio Insights app changed everything.
Verse’s team connected the customer’s PPA to Aria, the clean energy platform designed for real-time validation, forecasting, and reporting.
- Data Validation: Aria automatically verified contract pricing line-by-line, checking every invoice against the agreed PPA terms.
- Generation Modeling: Using both machine learning and physics-based models, Aria recreated what the asset should have produced—based on weather, location, and resource availability.
- Anomaly Detection: It flagged errors like incorrect daylight savings adjustments, pricing mismatches, and performance shortfalls following major weather events (like a snowstorm that reduced solar output).
- Counterparty Support: Aria even generated templated messages the customer could send directly to the project developer to question discrepancies—with the data to back it up.
The Result
- $500,000 in cost recovery, including $100K from pricing errors and $400K from generation shortfalls
- 12 months of invoices validated, with clear, auditable reporting
- Improved developer communications with faster dispute resolution
- Executive-ready insights delivered via dashboards, reports, and APIs
But the biggest outcome?
Confidence. The customer no longer had to guess or hope their invoices were accurate—they had the data, tools, and automation to ensure every dollar was accounted for.
