PROBLEM:Non-Routine EventsTo achieve settlement-quality measurement of demand flexibility, non-routine exogenous changes must be accounted for.
COVID, "the mother of non-routine events," is an example of a massive exogenous event that renders traditional M&V impossible. However, factors such as changes in the economy and decarbonization policy also have profound effects on energy use. |
SOLUTION:
The GRIDmeter™ methods apply stratified sampling, or individual load shape matching, to identify non-participant comparison groups that can adjust for COVID and other exogenous factors on an hourly basis.
The GRIDmeter™ methods have proven accurate through empirical testing for both residential and commercial applications. |
IMPLEMENTATION:
Open-Source Recurve has published an open-source code base that can be used to run the GRIDmeter™ methods at scale.
This code repository is available to all parties without restriction under an open-source license. |
PROJECTOpen-source methods developed in a public data-driven process.
|
METHODSStratified comparison groups that deliver settlement-quality results.

CODEOpen-source Python code available to all parties without restriction.

Stay at home orders due to COVID, economic changes, and the electrification of buildings, all change patterns of energy use, overwhelm traditional measurement techniques for demand flexibility and energy efficiency.
To generate a settlement-quality, revenue-grade calculation for demand flexibility and energy efficiency, M&V must adjust for these outside events.
To generate a settlement-quality, revenue-grade calculation for demand flexibility and energy efficiency, M&V must adjust for these outside events.
To solve this problem, Recurve received funding from the DOE to convene a public working group to develop methods and code to generating standardized, automated comparison groups capable of isolating the effects of exogenous changes on portfolios.
Through this process, the GRIDmeter™ was proven capable of enabling accurate measurement of behind the meter distributed energy resources impacts, net even of the extreme effects of COVID on energy use, for commercial and residential buildings. The GRIDmeter™ methods and open-source GRIDmeter™ code repo are the outcomes of this process. They are available for use by any party, without restriction, to enable settlement-quality measurement and verification during this time of COVID, and as we accelerate the decarbonization of buildings going forward. |
