Episode notes
Iberian Energy Market Context
- Spain and Portugal are rapidly deploying renewable energy, primarily solar PV.
- This rapid growth, coupled with slow demand growth and favorable weather for other renewables, led to negative energy prices and grid curtailment.
Impact on Asset Management
- Negative prices and curtailment require smarter asset management and financial strategies.
- Predicting curtailment and optimizing dispatch strategies are crucial for maximizing revenue.
Predicting Curtailment
- Base curtailment predictions on historical data and node analysis.
- Recognize that predictions are estimations based on past data, not guarantees of future events.
