❓ FAQ
How accurate are the forecasts?
Our model achieves 8-12% MAPE (Mean Absolute Percentage Error) on 30-day backtests against actual ERCOT prices. This is 30-40% more accurate than naive baselines. However, electricity prices are inherently unpredictable during extreme events.
What data sources do you use?
We use publicly available ERCOT market data (LMP, demand, generation) combined with NOAA weather data. All data sources are free and openly accessible.
Can I cancel anytime?
Yes. All subscriptions are managed through Gumroad and can be canceled at any time. No contracts, no commitments.
Do you offer API access?
Not yet. V1 is HTML/CSV reports only. API access is planned for Q2 2026 if demand justifies it.
Is this financial advice?
No. PowerCast provides data and predictions for informational purposes only. Users should conduct their own due diligence before making trading decisions.
