# HelioExpect

> Forecasting, monitoring, and procurement software for renewable energy operators. Built by power engineers. In production across 4+ GW and 30+ sites in 3 countries, at 98% average forecast accuracy.

HelioExpect serves IPPs, utilities, and O&M teams running solar, wind, and storage assets. The product covers three connected jobs: predicting generation (for scheduling and deviation settlement), detecting underperformance before it compounds, and closing the loop from alert to purchase order.

## Products

- [Solar and wind forecasting](https://www.helioexpect.com/forecasting): ML-corrected generation forecasts using GraphCast and cloud motion vectors. 15-minute updates, 14-day horizon, delivered via dashboard, email, or FTP with real-time comparison against actuals.
- [Wind forecasting](https://www.helioexpect.com/forecasting/wind): Turbine-level wind generation forecasts. Hub-height wind speed modelling, turbine-specific power curves, direction-dependent wake losses, air density correction, and ramp event detection, delivered in 15-minute scheduling blocks.
- [Long-term forecasting](https://www.helioexpect.com/forecasting/long-term): Long-horizon generation estimates for planning, financing, and resource assessment.
- [Forecasting delivery and API docs](https://www.helioexpect.com/forecasting/docs): Integration formats, delivery channels, and data schemas for forecast consumers.
- [Predictive monitoring](https://www.helioexpect.com/monitoring): Multi-level performance tracking across plant, inverter, and string. Fuses SCADA, IoT, weather, and ticketing data to surface faults before they cascade.
- [Monitoring docs](https://www.helioexpect.com/monitoring/docs): Data ingestion, alert configuration, and reporting reference.
- [Procurement and sourcing](https://www.helioexpect.com/procurement): Procure-to-pay for renewable O&M — monitoring alert to requisition, RFQ and reverse-auction sourcing, configurable approval matrix, goods receipt, tax-compliant invoicing, and a two-sided vendor portal.
- [Procurement docs](https://www.helioexpect.com/procurement/docs): Requisition, approval, and vendor-portal reference.
