March 7, 2023  | OpenEEmeter Technical Working Group Meeting

3/8/2023

Thanks to everyone who joined us for yesterday's OpenEEMeter technical working group meeting.

Adam Scheer led off the meeting by reiterating the high-level goals for the CalTRACK 2.1 Daily model which are to improve specific and known areas of model bias and gain computational efficiency in the process. He explained the need to solve seasonal and weekend/weekday bias by adding parameters and optimization steps without creating an overfitting problem or making the model so complex that it can't be scaled to hundreds of thousands or millions of meters.

For the CalTRACK Hourly model, Adam laid out issues to discuss in future meetings, including remedying known small bugs, specifying demand response baselines, and incorporating solar PV modeling.

Adam then introduced James Fenna from Carbon Co-op to discuss some challenges and modifications needed to implement CalTRACK (specifically eeweather) in the U.K. and internationally. In particular, James discussed the problems of calibrating for metric temperatures and the need for different sources of weather data internationally.

Adam then led a more detailed discussion of the specific tradeoffs of adding parameters to address seasonal bias in the model.

The group discussed how seasonal bias is a problem that has been known for decades, and how much effort should be put into improving the Daily model versus Hourly.

February 7, 2023 | OpenEEmeter Technical Working Group Meeting

Thanks to all who attended the most recent CalTRACK working group meeting.

McGee Young opened this meeting with some words for Shuli Goodman of LFEnergy Foundation who recently passed away. McGee made the point that Shuli was instrumental in helping to give the OpenEEmeter credibility and a home. Shuli had a vision that open source/open standards could do for energy what it's done for other industries, like the Internet. Under her leadership LFEnergy has grown as an umbrella to many innovative projects. She will be missed.

The technical discussion explained the current goal of examining sources of bias or error in CalTRACK 2.0 and potential solutions. The group discussed the need to balance adding additional parameters against the risk of overfitting.

Upcoming CalTRACK Methods Meeting (Feb 7th)

2/6/2023

0 Comments

 
Picture
Join the CalTRACK working group to help improve the CalTRACK methods and the LFE OpenEEmeter open-source software. This working group is comprised of many of the leading users of these methods and code. Come join the process!

Meeting topics will include
  • Progress is being made on CalTRACK 2.1 daily methods
  • Focus is on reducing known areas of bias (seasonal and weekend/weekday for example) to produce a more robust, reliable, and flexible model
  • Early results show promise and will be shared with the working group
  • Preliminary CalTRACK 2.1 is showing the ability to identify meters that benefit from a method in which independent model components are developed by season and/or weekends vs. weekdays

CalTRACK 2.1 Working Group Kick-Off 2022

11/2/2022

LF Energy and the OpenEEmeter project team are pleased to re-launch the CalTRACK working group to incorporate updates to the methods and code and formally enfold CalTRACK under the OpenEEmeter project umbrella.

​What Is CalTRACK
The CalTRACK methods and OpenEEmeter codebase are a standard and transparent set of procedures designed to calculate savings based on metered energy consumption. Since their development these procedures have been used to measure the impacts of dozens of energy efficiency programs across the United States and as a settlement tool for performance-based demand flexibility markets. 
​​
​The original CalTRACK working group members included the California Energy Commission, the California Public Utilities Commission, Pacific Gas and Electric Company, DNV GL, Energy Savvy, and a host of other contributing members (CalTRACK history). The OpenEEmeter codebase was donated to Linux Foundation Energy (LFE) as an open-source project in 2019 to culminate the group's efforts.

What's Next
In the last few years, the need for accurate and standardized meter-based methods has grown, along with the market for scalable and integrated demand-side programs. In 2020-2021, COVID-19 disruptions heightened the importance of identifying and removing the impacts of external (non-program) factors on energy consumption. In partnership with the Department of Energy, Recurve developed the GRIDmeter comparison group methods to address this challenge. Similarly, California's 2020 heat wave and rolling power outages exposed the necessity for more reliable demand response methods. In response, Recurve developed the FLEXmeter methods on behalf of the California Independent System Operator. CalTRACK and GRIDmeter are the foundations of FLEXmeter, which can accurately measure the impact of demand response events, even during extreme heat waves, and, importantly, support integrated EE and DR measurements. 

While CalTRACK 2.0 is foundational to all of these approaches, we believe that further updates to the methods and the OpenEEmeter code will promote greater accuracy and confidence in the impacts of behind-the-meter resources and could help bring a wider variety of demand-side programs to the table. We look forward to working with other stakeholders and partners who have used CalTRACK and the 
OpenEEmeter for their own initiatives and would like to contribute to this process.
​
On November 22, 2022 Recurve will host the CalTRACK 2.1 kickoff meeting. The CalTRACK 2.1-OpenEEmeter development process will follow the LFE Charter and Code of Conduct.  


Methods development is an experimental process that can benefit from the input and experiences of many. The collaborative feedback loop is an exciting aspect of open-source development. The successes and failures at every stage represent progress for all to see and provide many points for collaboration and for new ideas to emerge. We can't wait to get the band back together.

Energy Market Methods Consortium (EM2) Kickoff

2/23/2019

2 Comments

 
Picture
The next phase of collaboration on CalTRACK has commenced!  CalTRACK and the OpenEEMeter are migrating to new governance structures and “homes” aligned with the Linux Foundation, one of the largest supporters of open source projects in the world. 

CalTRACK methods will continue to be developed under the umbrella of a new group called the Energy Market Methods Consortium (EM2). The CalTRACK methods working group will continue to address updates to the avoided energy use tool and two other working groups will tackle the related topics of adjustments for grid integration (GRID) and secure data transfer (SEAT). The governance of this the project and the three working groups will be under the umbrella of charters approved by the Joint Development Fund. 

Bruce Mast of Ardenna Energy will serving as an Interim Executive Director to administer the processes outlined in the EM2 charter. Those who would like to join a working group or the technical steering committee can contact Bruce for more information on membership.  All meetings are open to the public.
A video of the kick off meeting, held on February 19th, provides more detail on the structure of the EM2. Unfortunately the recording picked up the video boxes which may impair viewing of some of bullets; so the slide deck is available below the video link.
