Why forecast accuracy matters
As solar capacity continues to expand worldwide, plant operators face mounting pressure from Transmission System Operators (TSOs). The variable nature of solar irradiance (driven by cloud motion, atmospheric conditions, and seasonal patterns) creates direct financial and operational risks:
- Imbalance penalties when production deviates from day-ahead or intraday commitments
- Forced curtailment when output exceeds grid absorption capacity without advance notice
- Oversized storage investments due to uncertainty in battery dispatch planning
- Inefficient spinning reserve usage, leading to energy waste, increased emissions, and accelerated equipment degradation
Without accurate weather forecasting, operators are left reacting to grid events rather than anticipating them.
How weather forecasting improves solar plant profitability
With advanced solar forecasting technology, such as Steadysun’s irradiance and production forecasting solutions, operators gain the data-driven confidence to act ahead of variability:
- Cut imbalance penalties in half through precise short-term and intraday production forecasts
- Right-size storage investments by aligning battery sizing with real forecast uncertainty ranges
- Maximize grid feed-in capacity and capture revenue from curtailment mitigation
- Reduce operational uncertainty across multiple forecasting horizons (from 15 minutes to 15 days)
What you will learn in this webinar
Learn how solar plant operators, portfolio managers, aggregators, and renewable energy traders maximize their market gains, protect their assets, and limit financial risk using high-accuracy solar production forecasts.
This session explores how integrating reliable forecast data helps tackle the challenges of energy market volatility:
- The impact of the solar boom: how the massive surge in PV capacity across Europe is rewriting the rules and increasing market players’ risk exposure
- Reducing balancing penalties: how ultra-precise weather data helps avoid the financial costs tied to deviations between actual and declared production
- Advanced forecasting methodologies: what combining multiple weather models delivers compared to traditional single-model approaches
- Trading strategy optimization: real-world cases showing how aggregators fine-tune their positions on short-term markets
- Frictionless technology integration: how to automate access to real-time irradiance and forecast data through secure API solutions
