Projects, articles, and references aligned with the Grid Coordination architecture — open protocols, direct utility-to-home communication, and site-level coordination rather than per-device cloud control.
A live, public electricity price service built on clj-oa3-vtn, serving hourly marginal prices from the CAISO Day-Ahead Market via GridX for PG&E and SCE rate schedules.

Canary Media — “As Californians electrify, can this tech combo prevent grid overload?” (March 2026)
Pacific Gas & Electric, California’s largest utility, is piloting a two-device architecture that pushes grid coordination all the way to the service-transformer level:
Together they let customers electrify without triggering panel or transformer upgrades that can cost anywhere from a few thousand to fifty thousand dollars, and let PG&E defer billions in grid investment. The pilot begins with PG&E employees’ homes, expanding to volunteer customers in 2027; ~1,000 homes will get Itron’s AMI 2.0 upgrade this year, potentially scaling to hundreds of thousands through 2030.
This is exactly the architecture Grid Coordination advocates: dynamic power limits at the site level, communicated over open networks to devices that respond autonomously — not per-device control from manufacturer clouds.
Grid Coordination’s founder participates in this pilot through one of the partner organizations.
The Utilize Coalition starts from an observation: “The power system is built to serve peak demand. However, electricity demand is near its peak in only a very limited number of hours per year. As a result, capacity across the entire power system often remains unused.” Their answer is to define and measure utilization properly, so that spare capacity can be filled rather than duplicated. Their case is set out in The Untapped Grid, a 43-page analysis prepared by The Brattle Group for GridLab and the Utilize Coalition in March 2026, and developed further in Beyond Peak: Defining, Measuring, and Optimizing Grid Utilization.
We endorse that premise without reservation, and the measurement agenda that follows from it. Their closing recommendation is that transmission and distribution capacity ratings and limits are “frequently confidential”, and that regulators and analysts should work with utilities and system operators to establish clear data definitions, confidentiality protections, and data-sharing processes. That is not an adjacent concern to this project. A per-customer power limit cannot exist until somebody publishes what the limit is. Their first recommendation is a precondition for our second signal.
Where the two fit together is straightforward, and the report draws the line itself: “Not a Policy Proposal. This paper quantifies the impact of increased system utilization, but does not propose specific policy mechanisms that could encourage increased utilization.” Utilization is the objective and the metric. A dynamic price and a per-customer power limit are one way to get loads to move so that the objective is met, instead of overbuilding to a peak that occurs a few hours a year. That is our argument, not theirs.

CEC Commissioner Workshop on Interoperability, November 4, 2026, 9:00 a.m. to 1:00 p.m. Pacific, remote only. The California Energy Commission is convening stakeholders on alignment among OpenADR 3.1, Matter, IEEE 2030.5, ISO 15118, OCPI and OCPP, under Docket 24-FDAS-02. Grid Coordination will attend, and our founder has been invited to present. See Policy & Advocacy for what the notice says and why it matters here.
Grid Coordination has demonstrated live OpenADR 3 dynamic pricing at the 2026 CEC/EPRI Electrification Summit, the CalFlexHub Symposium 2026 at Lawrence Berkeley National Lab, and the 2025 California Demand Flexibility Summit hosted by the California Energy Commission. See the demo for what the system does and how it is built.
