As wind and solar penetration grows, day-ahead forecasts get less reliable by the hour — and intraday markets have become the primary venue for correcting position and capturing value from those forecast shifts.
The structural driver
More weather-dependent capacity means larger forecast errors between day-ahead gate closure and delivery. That shows up as wider, more frequent intraday price swings — a direct opportunity for anyone able to re-trade continuously.
Capturing it safely
Capturing intraday volatility requires forecasts refreshed every 15 minutes and automated execution — not a desk checking screens once a day. Samawatt's engine re-trades continuously, with every decision logged and auditable.
