So, when are ERCOT''s Ancillary Services likely to be saturated for battery energy storage systems? The "simplistic" scenario: total battery energy storage capacity vs. Ancillary Service requirements. ... Regulation Up and Down, Responsive Reserve (PFR), ECRS, and Non-Spinning Reserve - then saturation looks likely to hit in June 2024. ...
At ERCOT, regulation up and regulation down services fall into the category of secondary frequency control. Because units need to have very fast ramping capability and there is a significant wear-and-tear effect when providing the RS service, the cost of procuring RSs is usually much higher than that of the energy services.

ERCOT Public. Regulation Service Methodology • ERCOT is not proposing any change to the methodology used to compute the minimum Regulation Service requirements for 2022. • The preliminary Regulation quantities for January 2022 through October 2022 have been computed using current methodology (2020 and 2021 …
•ERCOT currently recognizes 3 main types of reserves as commercial products: •Regulating Reserve, divided into: •Regulation-Up and Regulation-Down (signals to generation on typically 4 by 4 second basis, collectively "regulation AS"), •Responsive Reserve (full deployment within 10 minutes; known as "spinning reserves" in other
This paper presents a statistical analysis of the impact of different NPRR changes over ERCOT procured Regulation-Up and Regulation-Down operational …
The top-down control. In the top-down control, the populations of the organisms lower trophic levels (bottom of the pyramid) are controlled by the organisms at the top. This approach is also called the predator-controlled food web of an ecosystem. The "top-down" or "bottom-up" refers to the ecological pyramid describing trophic levels.
Supply and Demand. Supply and Demand is a graphical representation of the ERCOT system''s current power supply (capacity) and demand using Real-Time data, as well as projected power supply (capacity) and demand from hourly forecasts and seasonal forecasts. *Note: The 6-Day Forecast graph should only be used as a relative indication …
The terms "Regulation Up" and "Regulation Down" refer to generation capacity and controllable load that is being used all the time to keep the grid frequency at 60 Hz. High frequency (over 60 Hz) can be …
Regulation Service consists of resources that can be deployed by ERCOT in response to changes in ERCOT System frequency to maintain the target ERCOT System frequency within predetermined limits according to the Operating Guides. ERCOT is required to evaluate normal requirements for Reg-Up Service and Reg-Down Service on …
Eolian also said that batteries providing ERCOT''s Regulation Up and Regulation Down ancillary services — which increase or decrease generation output to maintain system frequency — will be ...
ERCOT noted that ESRs duration-limited nature poses a unique problem in the context of Ancillary Services. While ERCOT procures all AS products for each hour, only Regulation Up Service (Reg-Up) and Regulation Down Service (Reg-Down) are routinely deployed every hour.

Since units need to have very fast ramping capability and there is a significant wear-and-tear effect when providing the RS service, the cost of procuring RSs is usually much higher than that of the energy services. Therefore, …
There are 4 ancillary services in the ERCOT market: Regulation Service – Up; ... ERCOT uses Regulation Service Up and Down to balance the grid when supply and demand fluctuate due to weather, generation outages, or transmission outages. They use Responsive Reserves and Non-Spinning Reserves if the grid is close to entering a state …
