Why is uncertainty quantification often absent or insufficient in energy planning studies?
Computational cost (2-3 orders of magnitude), methodological impediments, lack of data for new technologies, perception barrier (policymakers prefer point estimates).
Key Takeaway
Uncertainty quantification is systematically neglected due to cost, methodology, data, and perception barriers.
Detailed Explanation
Uncertainty quantification is systematically neglected for the following reasons: (1) the computational cost (100-1000 Monte Carlo runs, 500-2000 bootstrap resampling iterations, 10-50 models in ensemble methods) multiplies the baseline computational requirement by 2-3 orders of magnitude, (2) methodological impediments (proper uncertainty decomposition (aleatory vs. epistemic), calibration testing (coverage probability of the prediction interval), sensitivity analysis (Sobol indices, Morris screening) require advanced statistical know-how often absent in engineering-leaning energy planning teams) (3) Lack of data – an assessment of the uncertainty in the model inputs requires historical data on the distribution of the parameters. This is not available for newer technologies (offshore wind in Turkey, large-scale battery storage) and policy variables (future carbon prices, renewable subsidies) (4) Perception barrier (policymakers desire deterministic point estimates, which they perceive as more actionable, rather than probabilistic ranges). There is, therefore, little incentive for researchers to expend any effort on quantifying uncertainty, even though this would allow for a decision-making process which is more risk-aware.
Why It Matters
Research significance: Motivates Monte Carlo dropout and bootstrap in framework.
Energy policy relevance: Explains why Turkey's plans lack uncertainty.
Methodological contribution: Justifies three-tier uncertainty strategy in framework.
