ERCOT charges are complex. 4CP transmission charges, real-time LMP spikes, and ancillary service costs all affect your monthly bill. This page explains the key concepts LumenicGrid targets.
ERCOT (Electric Reliability Council of Texas) is the independent grid operator that manages power flow for roughly 90% of Texas's electricity load. It operates a deregulated wholesale market where electricity prices fluctuate in real time based on supply and demand.
Because Texas runs its own isolated grid — not connected to the Eastern or Western Interconnections — prices can move dramatically. During summer heat waves or winter storms, real-time prices can spike from $30/MWh to $5,000/MWh within minutes.
For large commercial and industrial customers — including Bitcoin miners and data centers — ERCOT charges appear in two main forms: energy charges (real-time consumption at LMP prices) and transmission charges (based on capacity and demand coincidence).
Transmission and distribution charges from your TDSP are calculated based on your load during the four 15-minute intervals that coincide with ERCOT's four highest system-load peaks — one per month in June, July, August, and September.
These four 15-minute windows determine a significant portion of your annual transmission charges. The challenge: you don't know exactly when they'll occur. Miss them at full load, and you pay the maximum rate for the following year. Curtail successfully during each one, and your transmission charges drop substantially.
GridBrain monitors ERCOT real-time LMP, system load data, weather forecasts, and historical coincident peak patterns. When probability of a 4CP window exceeds a threshold, curtailment signals are sent to your systems. The model accounts for time-of-day, temperature, wind generation levels, and LMP trajectory — not just current price.
We track outcomes during the shadow trial to calibrate the model against your actual ERCOT load zone and historical exposure. The Savings Validation Report at Day 60 shows whether the predicted curtailments would have reduced your 4CP charges.
Depending on your electricity contract, you may have direct or indirect exposure to real-time LMP prices. Pass-through contracts are common in Texas's deregulated market, especially for large industrial customers who accept market risk in exchange for lower base rates.
During grid stress events — heat waves, generator trips, low wind periods — LMPs can spike dramatically. A 50 MW facility running at full load during a $1,000/MWh spike pays $50,000 for that single hour. Across a summer, exposure can be significant.
LumenicGrid's LMP monitoring tracks your load profile against real-time prices every 5 minutes. Curtailment signals are dispatched when price exceeds your configured threshold. During the shadow trial, we track how often that threshold was crossed and what curtailment would have saved.
The 60-day shadow trial shows your actual 4CP and LMP exposure based on real ERCOT data and your facility's load profile.
