What is ERCOT reserve margin?

The planning reserve margin is the difference between the total generation available in the ERCOT system and the forecasted firm peak demand (i.e., peak load minus interruptible customers.)

What are ERCOT ancillary services?

Ancillary services are products used by ERCOT to maintain reliability minute-by-minute, 365 days per year. Responsive Reserves and Non-spinning Reserves are used by ERCOT when the grid is at, or near, a state of emergency due to inadequate generation.

Does ERCOT sell electricity to other states?

Texas’ ERCOT power grid is one of three in the Lower 48 states. Because it does not provide power across state lines, the Federal Energy Regulatory Commission has no jurisdiction over ERCOT.

Why doesn’t Texas have a capacity market?

There is no capacity market paying generators to ensure there will be enough power to meet peak demand. That’s what we have in the Texas energy market. Over the last 10 years, the revenues collected by the generators were less than the cost of providing the electricity. That is not going to produce a reliable system.

Does Texas produce more energy than it consumes?

Texas produces more electricity than any other state, generating almost twice as much as Florida, the second-highest electricity-producing state. Texas is the largest energy-producing and energy-consuming state in the nation.

What is a controllable load resource?

A Controllable Load Resource is a Load that can vary its electric usage based on a real-time set point received from an outside source (its QSE) and independently provide immediate response to frequency deviations on the ERCOT grid.

What is responsive reserve service?

Responsive Reserve Service means the daily operating reserves that are intended to help restore the frequency of the interconnected transmission system within the first few minutes after the occurrence of an event that causes a significant deviation from the standard frequency.

What does ERCOT mean for resource adequacy?

****NEW**** The charts now show project capacity that ERCOT has approved for grid synchronization. This revised file reflects capacity changes for several installed solar and wind plants that were not updated during 2019 based on new Resource Asset Registration Forms (RARFs).

What is the difference between ERCOT and ERCOT operational reports?

In contrast, ERCOT operational reports include additional project capacity that has been approved for grid synchronization but not commercial operations.

What is the minimum reserve margin for ERCOT?

The current minimum target reserve margin established by the ERCOT Board of Directors is 13.75 percent of peak electricity demand to serve electric needs in the case of unexpectedly high demand or levels of generation plant outages.

How does the ERCOT wind Integration Report work?

This report contains information to track wind as a percentage of the ERCOT load. The report shows a high level summary of the average peak load, peak hour, current wind record and date, maximum instantaneous wind value, time and wind as a percentage of the load.
