Do you struggle understanding and forecasting performance of your Power Purchase Agreements? Many clean energy buyers share this same challenge. In this session you will learn an easier way to:

  • Organize the influx of monthly invoices
  • Audit and identify costly invoice errors
  • Obtain insights into project operations
  • Forecast settlement across confidence bands

We shared real-world use cases where clean energy buyers have found simpler, more efficient ways of understanding and reporting on their portfolios. We even gave specific examples of corporations uncovering hundreds of thousands of dollars in previously undiscovered errors. Watch the recording of the full session below.
