DAME rewrote the market for PG&E.
We're monitoring the impact closely.
Most of the EDAM conversation has focused on utilities joining for the first time. PG&E is different. As a native CAISO scheduling coordinator, you've operated in this market for years. It's now running on different rules, different products, different price signals, and a data landscape that didn't exist before May 1.
DAME redesigned the market you've operated in for years. New products. New price signals. 2,135 new pricing locations. More than 50 new reports. And the market will keep evolving long after May 1. Yes Energy has supported CAISO participants through every major market transition since 2008, and we're trusted by every balancing authority committed to EDAM.
Two new market products are reshaping your price signals
DAME introduced Imbalance Reserves (IRU/IRD) and Reliability Capacity (RCU/RCD) as new day-ahead products. Imbalance Reserve procurement now creates additional binding transmission constraints, generating new congestion shadow prices that change the signals your team relied on.
2,135 new price nodes launched May 1, changing the data landscape
EDAM/DAME added 2,135 new pricing locations and launched more than 50 new CAISO reports on May 1, with 40+ existing reports updated. The day-ahead congestion data your team uses to evaluate positions and CRR performance now looks different.
CRR revenue calculations changed on May 1 for every existing contract
Starting May 1, DA congestion in Yes Energy's FTR tools incorporates imbalance reserve up and down prices, not just energy congestion. Historical CRR path performance now includes a new component that didn't exist before go-live.
Load growth is compounding the challenge
With 4.6 GW of data center projects in final engineering, PG&E is absorbing DAME's new data complexity during the largest capacity expansion in its recent history. The signals your team is learning to interpret are directly tied to the load conditions PG&E is creating.
We know the implementation challenges don't end at go-live.
In an April poll of CAISO market participants attending a Yes Energy webinar on EDAM and DAME readiness, 86% said they were still working through key areas or had just started evaluating the impact.
New price signals your existing models weren't built for
DA prices now reflect dispatch decisions across multiple balancing authorities, and Imbalance Reserve procurement is creating congestion patterns in locations where they didn't exist before. Models and analysis tools built on historical CAISO-only data will need to be recalibrated.
CRR data that looks different
Yes Energy's FTR tools now show total DA congestion with and without imbalance reserve components, so teams can identify whether CRR performance is being driven by energy congestion, IRU, or IRD. Teams that miss this breakdown risk making positioning decisions on incomplete data.
Continuous rule changes after go-live
CAISO issued more than 180 Business Practice Manual updates through DAME and EDAM development, and interpretations continue to evolve post-go-live. Our team maintains ongoing collaboration with CAISO on open market issues, so customers hear about changes before they affect their data or positions.
Also navigating DAME on the back-office side?
The same changes affecting your market data, new Imbalance Reserve and Reliability Capacity products, updated charge codes, new settlement constructs, are landing on settlements and billing teams at the same time. Yes Energy's PowerCore is trusted by every balancing authority committed to EDAM. If your settlements or market operations team is working through the post-DAME reconciliation challenge, we're glad to connect on that too.
No demo. No pitch deck. Just a conversation.
