Dynamic reserve dimensioning
Move beyond static reserve sizing.
Our Dynamic Reserve Dimensioning solution uses probabilistic forecasting, interconnector schedules, and grid constraints to reflect real system conditions, helping you reduce costs, improve reliability, and align with evolving market requirements.
Built for your success
Forecast error modelling
Quantify uncertainty from renewables with probabilistic insights.
Anticipate interconnector schedules
Model the expected impact of HVDC in your N-1 analysis
Product-level allocation
Assign your reserve needs to fast and slow products.
Optimize procurement strategy
Incorporate contributions from non-contracted bids, multi-area reserve dimensioning and sharing agreements.
