The ability to predict consumption and generation with **utmost accuracy** determines economic success and grid balance. At **alitiq**, we master the entire spectrum of forecasting: from **Nowcasting** for agile real-time correction to **(Day-Ahead) Forecasting** and medium-term predictions for strategic planning. 🔄 But what distinguishes Nowcasting from Forecasting? And how do we use artificial intelligence to deliver the best output on every timeline? 🧠 ![Nowcasting vs. Forecasting Visualization](https://alitiq.com/lovable-uploads/nowcasting-forecasting-visualization.png) Nowcasting vs. Forecasting Visualization * * * ## Nowcasting: Agile Real-Time Correction (Intraday) ⏱️ **Nowcasting** operates on a timeline of **minutes to approximately two hours**. This is primarily about **responsiveness** and managing the last mile before actual delivery or consumption. ⚡ ### The alitiq Intraday Strategy: Reactive and Predictive Our current nowcasting is already extremely sharp: it's based on the continuous assimilation of **current measurement and performance data** from our customers. We detect deviations from the day-ahead forecast in real-time and can **adjust forecasts intraday** to smooth load profiles and minimize the risks of short-term market fluctuations. 📉 ### NowcastAI Research Project: The Scientific Leap Forward 🔬🚀 Standstill means regression. That's why we're advancing our nowcasting through the joint **NowcastAI research project** with Ventus GmbH into a **predictive** discipline. Previously, we reacted to deviations, such as actual performance drops. In the future, however, we want to recognize the **cause** **before** the effect occurs: - **Focus on Solar Irradiance:** NowcastAI aims to develop an AI-based short-term weather model that predicts **solar irradiance** with unprecedented precision – crucial for volatile PV generation. 🌞 - **Top-Class Data Fusion:** The system integrates **satellite images, radar data, and ground observations** into an advanced machine learning framework. 🛰️ - **Scientific Advantage:** By using **high-performance computers (HPC)** and processing this geophysical real-time data, we generate **minute-accurate predictions** of actual weather developments, such as cloud movements, at a spatial resolution in the kilometer range. **Your Advantage:** We will be able to integrate the **approaching cloud cover** into our forecasts **before** it appears in your generation data. This makes our nowcasting not just a correction tool, but an **active optimization instrument in real-time**. ✅ * * * ## Forecasting: The Wide View with AI Precision (Day-ahead and Beyond) 🤝📅 **Forecasting** describes all predictions that extend beyond a few hours – our view of the **day-ahead market**, the week, or the quarter. Since no current measurement data is available yet, predictions are based on complex modeling, primarily **numerical weather prediction** (Numerical Weather Prediction, NWP). ☁️☀️ ### The alitiq Engine: From Weather Data to Performance Forecasting Conventional forecasting models often reach their limits because they inadequately represent the **individual relationship** between weather and specific energy-related processes. This is precisely where the full **power of the AI-driven alitiq engine** demonstrates its strengths. 💪 - **Solid Data Foundation:** We feed our engine with the most robust meteorological data from leading institutions such as the **German Weather Service (DWD)** and **ECMWF**, supplemented by numerous international models and our own meteorological expertise. 🌍 - **Individual Analysis (Onboarding):** During our onboarding, scientific depth unfolds: Our AI analyzes **individually** how specific weather parameters (e.g., wind, temperature, global radiation) have **actually influenced** your generation or consumption processes in the past. 🔬 - **Precise Projection:** Only this profound, **physically and statistically founded causal analysis** enables us to transform raw NWP weather data into **highly specific, energy-system-relevant performance forecasts**. **Your Advantage:** The day-ahead forecast is so precisely tailored to your individual facilities that it provides a **reliable foundation** for energy trading, balancing group management, and resource planning. 💰 * * * ## Conclusion: alitiq – Your Partner on Every Timeline Optimal control of energy processes requires a seamless chain of precise forecasts that unite scientific depth with maximum agility. At **alitiq**, we're not limited: We deliver **individually trained forecast intelligence** for the day-ahead market and ensure through our nowcasting – and soon through the innovations of NowcastAI – **agile control** in intraday operations. **Trust alitiq to transform the complexity of energy markets into your competitive advantage. We keep your forecast in view – from the next minute to the next day!** 👀 ### Ready to Transform Your Business? Discover how alitiq's forecasting intelligence can optimize your operations.
