Overview

Accurate energy savings reporting is essential in performance-based energy contracts. However, Non-Routine Adjustments (NRAs changes unrelated to retrofit works can significantly distort savings. These include operational schedule changes, occupancy fluctuations, tenant variations, or external disruptions. If not accounted for, NRAs can inflate savings claims and lead to inaccurate compensation.

To address this challenge, Ark Energy developed the NRA Analytics Tool, a smart statistical engine integrated into Ark’s M&V workflow. The tool isolates and quantifies NRA impacts, corrects baseline distortions, and ensures energy savings reflect true performance improvements across commercial, residential, and industrial projects.
 

Challenge

In many projects, NRAs can inflate reported savings and create inaccuracies in energy performance verification. Our analysis shows that:
 

• Manual spreadsheet–based NRA handling introduces up to 55–60% inaccuracies, due to inconsistent assumptions, formula errors, and subjective adjustments

• NRAs can overstate energy savings by 20–40%, leading to potential overpayment to ESCOs

• In large portfolios, manually identifying NRA events becomes time-consuming and prone to omission

• Stakeholders lose confidence when savings reports do not reflect actual retrofit-driven performance

With multiple projects across different sectors, our client needed a consistent, scalable, and data-driven solution to validate energy savings fairly and transparently.

Solution

Ark Energy deployed the NRA Analytics Tool, designed to detect, quantify, and correct NRA-related distortions using:

Key Capabilities:
 

• Automated NRA Detection: Uses statistical modeling to identify abnormal consumption patterns caused by non-retrofit events

• Quantified Adjustment Calculations: Applies calibrated corrections to reflect true energy performance

• Operational Data Integration Incorporates tenant schedules, occupancy profiles, and external factors for more precise analysis

• Portfolio-Level Scalability Successfully deployed across 11 diverse projects (commercial, industrial, residential)

Conclusion


The NRA Analytics Tool significantly enhances the accuracy and credibility of M&V reporting, preventing overcompensation and strengthening decision-making.
