Why this matters
A 12-month production-normalized baseline is the foundation of any credible energy efficiency program โ it separates normal seasonal variation from real savings. A coefficient of variation above 10% typically signals that weather, product mix, or operating shifts dominate consumption and must be accounted for before quoting a retrofit. If your baseline flags more than a handful of outlier months, you likely need segmented baselines rather than a single mean. Compare verified options on TUNA Connect.
