Energy and load forecasting: Managing volatility, enabling predictive planning

Energy markets are becoming increasingly volatile. Fluctuating energy prices, the growing share of renewable energy, and complex regulatory frameworks are making predictive energy management a strategic necessity. Without a clear understanding of future energy demand, companies risk inefficient planning, higher procurement costs, and significant additional expenses caused by unexpected peak loads.

This is where our predictive load forecasting solutions come in. Based on historical consumption data and external influencing factors, we generate highly accurate forecasts of future energy demand – from 15-minute intervals to forecasting horizons spanning several years. We replace uncertainty with data-driven planning reliability and provide companies with a powerful tool for actively managing and optimizing energy procurement, production planning, and load management.

While conventional forecasting methods often provide only a single value (point forecast), modern approaches also account for uncertainty and the hierarchical structure of energy systems. Hierarchical structures – such as the aggregation of devices into systems, systems into production lines, and production lines into entire facilities – require consistency between subsystem forecasts and the forecast of the overall system.

In addition, probabilistic forecasting methods provide not only an expected value, but also a probability distribution that captures the range of possible future scenarios.

Our approach: A methodological toolbox for high-accuracy forecasting

There is no universal approach to forecasting. Every company, process, and site has its own unique consumption profile. That is why we use a flexible, multi-stage methodology that combines advanced statistical methods, machine learning, and deep learning to develop forecasting models tailored to specific operational requirements.

  • Energy and load Forecasting: Managing volatility, enabling predictive planning Energy markets are becoming increasingly volatile. Fluctuating prices, the growing share of renewable energy, and complex regulatory frameworks are making predictive energy management essential. Without a clear understanding of future energy demand, companies risk unnecessary costs and inefficient planning.
  • Our predictive load forecasting solutions combine historical consumption data with external influencing factors to generate highly accurate forecasts ranging from 15-minute intervals to multi-year forecasting horizons. This creates data-driven planning reliability and supports optimized energy procurement, production planning, and load management.
  • Modern forecasting approaches account not only for uncertainty, but also for the hierarchical structure of energy systems. Forecasts for the overall system must remain consistent with the aggregation of subsystem forecasts. Probabilistic forecasting methods therefore provide not only an expected value, but also the range of possible future scenarios.
  • Our approach: Every company has its own operational and consumption patterns. By flexibly combining statistical methods, machine learning, and deep learning, we develop forecasting models tailored to specific operational requirements.

Forecasting workflow at a glance

  • There is no universal forecasting solution. Our flexible approach combines advanced statistical and AI-based methods to develop the optimal model for specific operational requirements.

    • Deterministic forecasting: Precise expected values
      Deterministic models provide a precise forecast value for each time step (e.g. "10.2 MWh at 2:15 p.m."). These point forecasts are easy to interpret and form the basis for many operational decisions. To achieve this, we apply advanced algorithms such as gradient boosting (XGBoost) and neural networks (TCN, Transformer, Few-Shot Learning), which capture complex relationships from historical data and external influencing factors (e.g. production data and weather conditions).
    • Probabilistic forecasting: Managing uncertainty intelligently
      We go beyond single-value predictions by providing realistic forecast intervals (e.g. "with a probability of 90%, consumption will range between 9.8 and 10.6 MWh"). Similar to a weather forecast that indicates the probability of rain, this approach directly quantifies uncertainty and risk. This enables more informed, risk-based decision-making, for example when hedging energy volumes on the market. To achieve this, we apply advanced methods such as quantile regression and ensemble models.
    • Hierarchical forecasting: Consistency across the entire organization
      Companies typically have hierarchical structures: machines form lines, lines form facilities. Using hierarchical forecasting methods, we ensure that forecasts remain mathematically consistent across all levels. The sum of subsystem forecasts therefore corresponds exactly to the forecast for the overall site. This prevents inconsistent planning assumptions and ensures that all departments work with a consistent data foundation.
  • Every project starts with a clear business objective. Together with you, we determine the forecasting goals and create the foundation for successful project implementation.

    • Defining the forecasting objective: What should be optimized? Is the focus on minimizing energy costs, avoiding peak loads, optimizing storage operation, or supporting strategic energy procurement planning?
    • Defining the forecast horizon: We define the required forecasting horizon, which strongly influences model selection:
      • Short-term forecasts (intraday to 48 Hours): For operational shift planning, spot market trading, and real-time load management.
      • Medium-term forecasts (days to weeks): For optimizing energy procurement, maintenance planning, and the operation of energy storage systems.
      • Long-term forecasts (months to years): As a reliable basis for budgeting, capacity planning, and strategic investment decisions.
    • Defining success metrics: We define how forecasting performance will be evaluated – not only from a technical perspective (e.g. forecast error), but also from an economic perspective (e.g. cost savings).
  • In this phase, we establish the foundation for high forecasting accuracy. We identify, collect, and prepare all relevant data to provide the forecasting models with the best possible information base.

    • Identification of relevant data sources: We use historical load profile data as the foundation and enrich it with valuable internal and external predictors, such as production schedules, weather forecasts, and calendar data.
    • Data integration and cleansing: All data streams are synchronized on a common timeline. We implement robust processes for data validation, outlier correction, and the intelligent imputation of missing values.
    • Feature engineering: We derive meaningful features from raw data that serve as important signals for forecasting models, such as weekdays, shift indicators, and temperature dependencies.
  • This phase represents the technical core of the project. Here, we develop, train, and validate forecasting models tailored specifically to your data and objectives.

    • Systematic model selection: Based on the forecasting objective and data complexity, we evaluate a broad range of models to ensure optimal predictive performance.
    • Training and rigorous validation: The model is trained using historical data, and its performance is objectively evaluated using a separate validation dataset (backtesting) before deployment.
    • Application of our core methodology: We implement the probabilistic and hierarchical approaches described in our methodology to quantify uncertainty and ensure forecast consistency.
    • Objective performance evaluation: Model performance is assessed using industry-standard metrics (e.g. MAE and RMSE for point forecasts; Pinball Loss for probabilistic forecasts).
  • A forecasting solution only delivers value when it is seamlessly integrated into operational processes and continuously provides reliable results.

    • Forecasting as a service: We provide forecasting models via standardized interfaces (e.g. REST APIs), enabling easy integration into existing energy management systems, dashboards, and trading tools.
    • Operational automation: The entire workflow – from data updates and forecast generation to result delivery – is fully automated.
    • Continuous monitoring and adaptive retraining: We continuously monitor forecasting performance during live operation. When operating conditions change (e.g. new systems or modified processes), automated retraining is triggered to ensure consistently high forecasting accuracy.
  • Use cases & their specific benefits: Putting forecasts into practice 

    Our load forecasts create direct economic value in key business areas:

    • Optimized energy procurement and trading: Purchase the right amount of energy at the right time on the spot market, or secure long-term contracts based on a well-founded demand forecast. Avoid costly balancing energy purchases.
    • Efficient scheduling and production planning: Synchronize your production schedules with forecasted energy prices. Strategically schedule energy-intensive processes during low-price periods.
    • Grid fee optimization through peak load forecasting: We accurately forecast your 15-minute peak loads. This allows you to take timely countermeasures (e.g., shutting down consumers, using battery storage) and significantly reduce your grid fees.
    • Management of on-site power generation and storage: Optimize the operation of your PV systems, CHP units, and battery storage. Our forecasts help you maximize self-consumption and optimally charge and discharge your storage systems.

FAQ – Frequently Asked Questions about energy and load forecasting

What is the difference between deterministic and probabilistic load forecasting?

A deterministic forecast provides a single expected value, while a probabilistic forecast also captures the range of possible outcomes. This makes uncertainty transparent and supports more informed, risk-aware decision-making.

Why are hierarchical forecasts important?

Hierarchical forecasts prevent inconsistent planning assumptions. By ensuring that forecasts at site level remain consistent with the aggregation of individual subsystem forecasts, all departments – from operations to procurement – work with the same reliable data basis.

Which data sources are considered in addition to energy consumption data?

In addition to electrical measurement data, we integrate weather data (temperature, wind, solar radiation), production and process data, market and price data, as well as seasonal influences as exogenous variables. Studies show that integrating such external data can significantly improve forecasting accuracy.

How are missing values in time series handled?

Missing values often occur due to sensor failures or communication errors. Depending on the extent and structure of the gaps, statistical imputation methods (e.g. interpolation, ARIMA) or learning-based models (e.g. LSTM, GAN) are applied.

Which error metrics are commonly used to evaluate load forecasts?

Point forecasts are typically evaluated using MAE (Mean Absolute Error), RMSE (Root Mean Squared Error), and sMAPE (Symmetric Mean Absolute Percentage Error). Probabilistic forecasts are assessed using metrics such as Pinball Loss and Coverage, which measure how reliably forecast intervals capture the actual values.
