Elephant Energy - Measurement and Verification Plan
Last updated:
Executive Summary
This document outlines the measurement and verification (M&V) methodology and data intake requirements for the electrification projects managed by Elephant Energy. The plan encompasses baseline establishment, metering infrastructure, data collection protocols, and savings calculation methodologies.
Evidence of Asset
Elephant Energy will upload a photo of a receipt of each Asset that will include the line-item of the subsidy provided by this program. They will also need to include the heat pump serial number on Asset upload.
Methodology Selection
We will use the Technical Specification: Quantifying energy use and emissions savings for electrification methodology.
We expect to receive 12 pre-intervention bills representing approximately 12 months of data that will be provided upon Asset upload. We expect to use “From NREL Building Selection, if no reporting data is available (Baseline: 1.1.2.2 and Reporting: 1.2.3). Approximately 1-year post-intervention, WattCarbon will receive 12 post-intervention bills representing approximately 12 months of data. After receiving and auditing this data, if it passes data sufficiency requirements, the Asset will switch to “From EEMeter Model, if reporting data is available (Baseline: 1.1.2.1 and Reporting: 1.2.2.1).
Data Requirements
Incorporated Data Requirements
The following are defined in the Technical Specification: Common Decarbonization methodology:
- Definitions
- Electricity Carbon Intensity Calculations

Timeseries Data
The timeseries data should be provided with the following columns:
| Field | Description | Required |
|---|---|---|
| start_date | The date representing the start of the bill cycle | Y |
| end_date | The date representing the end of the bill cycle | Y |
| energy_kwh | The energy consumption that took place during that bill cycle. | Y |
Data Management/Auditing Agreements
Timeseries Data
Elephant Energy is partnering with Bayou Energy, who will supply the electricity and gas bills used in this analysis. At around the time of the intervention, Bayou will provide the most recent 12 bills leading up to the intervention. These bills will be used to establish the baseline consumption of the building. One year following the intervention, Bayou will provide 12 post-intervention bills. These 12 bills should be after the intervention, starting with the second bill after the intervention.
For example, if an intervention took place on June 5, 2022, and the following bills existed for that home, we would take the bills 2021-06-18 through 2022-05-18 to represent the baseline consumption, we would exclude the bill 2022-06-10 as it is partially in both the pre -and post-intervention periods, and we would take the bills 2022-07-12 through 2023-06-13 to represent reporting consumption.
