Electricity Price Volatility
For merchant energy storage, volatility is the core driver of revenue. Unlike baseload generation, which relies on steady, average prices, a BESS thrives on the extreme highs and lows (the spread). OPTIMUS analyzes historical and forward-looking price volatility, focusing on the frequency of 'tail events' (e.g., Winter Storm Uri, summer heat domes, or sudden wind drop-offs). Our models ingest massive datasets of 5-minute and 15-minute real-time pricing to construct probability density functions, allowing investors to stress-test their financial models against P90 (downside) and P10 (upside) volatility scenarios.
Technical Overview
Proper assessment of electricity price volatility is critical for bankability and project finance. The OPTIMUS engine incorporates detailed physical models to evaluate the long-term impacts of operation.
Key Modeling Factors
