Reliably Measuring Demand-Side Interventions in a Solar PV World with OpenDSM
2025-09-24 18:00 - 19:00 (Europe/Helsinki)
LF Energy’s OpenDSM project (formerly OpenEEmeter) has recently approved and released a new model for measuring the energy impacts of demand-side interventions using hourly utility meter data. Developed via a collaborative effort of the OpenDSM working group, the new model replaces the previous hourly model (released with OpenEEmeter 3.0 and reflecting the CalTRACK 2.0 methodology) with an entirely new, modern, flexible, and extensible modeling framework. These improvements enable reliable application across a wide range of modeling contexts while avoiding many of the pitfalls that are commonly encountered with general-purpose models.
The new OpenDSM hourly model has a number of advantages over the previous version, including reduced overfitting, improved handling of outliers, increased flexibility, a more developer-friendly API, and computing times that are faster by a factor of 4-5. Most notably, the model opens the door to improved reliability for meters with solar PV generation. While the prior hourly model performed well for solar meters when cloudiness was consistent from year to year, annual variability in cloud cover created the potential for bias in measured savings. As the subset of meters with solar PV continued to grow, this bias represented a growing source of risk for demand-side portfolios. By introducing the option to include solar irradiance as a predictive variable, the new OpenDSM hourly model drastically reduces the risk of measurement bias for solar meters.
In this webinar, we will introduce the new OpenDSM hourly model, describe how it functions, and summarize key improvements. We will also detail the model’s performance on the 33,000 meter sample on which it was developed and tested.

LF Energy Summit Europe 2026
2026-09-15 - 2026-09-16 | Berlin
Grid operators have to deliver affordable, reliable, safe, clean energy, and they need digital infrastructure to do it. Across the sector, utilities and vendors are increasingly turning to open source as the proven way to co-develop the shared, non-competitive building blocks required to modernize the grid faster, at lower cost, and without dependence on single-vendor roadmaps.
LF Energy Summit Europe convenes utilities, grid operators, technology vendors, energy companies, policymakers, researchers, and practitioners to showcase how open source is being used today to build production-grade digital infrastructure for energy systems. The event highlights recent project developments, emerging innovations, and practical lessons from organizations shipping real code, not just ideas.
Attendees will gain insight from leading experts and practitioners into best practices, tools, and technologies; learn how to participate in and scale open source communities; and connect directly with the peers and leaders who are developing the digital grid together.
