Forecasting Instability in Solar Grids - SunPower Renewables

The Challenge

Frequent irradiance fluctuations and cloud transients led to forecasting errors, grid instability, and high DSM penalties.
In FY 2025, SunPower faced INR 46 crore ($5M) in imbalance penalties - projected to rise to INR 90 crore ($10M) from 2026 onwards.
Hybrid and wind integration further amplified forecasting inaccuracy, increasing operational and financial risk.

Global Context

This isn’t a regional problem — it’s a global forecasting crisis.

In the United Kingdom, balancing the national grid already costs over £500 million annually. By 2030, the National Electricity System Operator (NESO) warns this could reach £8 billion per year.

In the United States, the cost of day-ahead solar forecasting errors runs into hundreds of millions of dollars every year.

BioSky addresses this global gap with space-powered precision forecasting built for emerging markets.

• Projected Installed capacity by 2030: 500 GW

• Expected revenue loss/penalty outflow by 2030: $5B

• Potential to save the penalty outflow (50-70%) with better accuracy through BioSky’s product: $2.5B

• Hybrid and Wind add to the forecasting inaccuracies
