Energy System Modelling

Energy system modelling is a quantitative analysis method that creates mathematical representations of energy systems to simulate their behavior. While not defined by a single ISO standard, its application is critical for implementing risk management frameworks like **ISO 31000:2018** to assess energy transition and supply security risks. It is also a key tool within **ISO 50001:2018** Energy Management Systems for evaluating strategic options to improve energy performance. Unlike static energy audits, modelling is a forward-looking, dynamic tool for 'what-if' scenario analysis, enabling the development of resilient, long-term energy strategies for business continuity.

Application involves three key steps: 1) **Scoping & Data Collection**: Define the system boundary and objectives (e.g., carbon neutrality, supply resilience), then gather data on energy use, costs, and regulations. 2) **Model Development**: Select or build a suitable model and calibrate it with collected data to reflect reality. 3) **Scenario Analysis**: Simulate potential futures (e.g., carbon tax hikes, grid instability) to quantify impacts on cost and operations. For example, a global manufacturer used modelling to assess carbon pricing risks, guiding investments in efficiency and renewables. This led to a projected 15% reduction in energy cost volatility and ensured compliance with future climate disclosure requirements, improving their audit outcomes.

Taiwan enterprises face three main challenges: 1) **Data Scarcity**: Lack of granular energy data hinders model accuracy. The solution is to implement data governance aligned with **ISO 50001**, using IoT sensors and starting with pilot projects. 2) **High Technical Expertise**: Building and interpreting models requires specialized skills. Mitigation involves partnering with expert consultants and providing targeted internal training. 3) **Policy Uncertainty**: Taiwan's dynamic energy transition policies complicate long-term forecasting. The strategy is to use stochastic models that incorporate uncertainty and focus on building resilience (e.g., energy storage, demand response) rather than betting on a single outcome. A priority is establishing a data framework, with an initial model ready in 6 months.
