ERCOT Cites Expanding AMS Meter Implementation To Improve Data For Settlement, Credit & Load Management In 60-Point Roadmap For Reliability

ERCOT Will Evaluate Market Changes To Incentivize Sufficient Dispatchable Resources; Fuel Security

Will Assess Increased Transmission External To ERCOT To Other Power Regions

ERCOT today issued a "Roadmap to Improving Grid Reliability."

ERCOT stated in a market notice that, "The Roadmap identifies a number of initiatives ERCOT intends to take, or has already taken, to further enhance grid reliability and adequacy and improve communications."

Among the 60 points which are part of the ERCOT roadmap are the following:

• Work with Transmission and Distribution Service Providers and customers to expand AMS meter implementation to improve timeliness of accurate meter data for settlements, credit calculations, and load management.

• Conduct a study of credit best practices to reduce the risk of future under collateralization while avoiding uneconomic barriers to entry.

• Eliminate barriers to distributed generation, energy storage, and demand response/ flexibility to allow more resources to participate in the ERCOT market while also maintaining adequate reliability.

• Review reliability of current and projected resource mix and evaluate market changes to incentivize sufficient dispatchable resources.

• Evaluate market incentives to improve fuel security.

• Consider on-site fuel supply including contracts with remote secured supplies.

• Conduct a study to gauge the impact of varying levels of wind and solar penetration, including the impact of energy storage and dispatchable energy, as well as revenue adequacy for each of these levels.

• Evaluate the adequacy of ancillary services products and quantities to be procured.

• Evaluate requiring inverter-based resources -- such as wind and solar generators -- to provide additional reliability attributes such as grid-forming capability to protect Texans in the most dangerous grid conditions.

• Conduct a study to understand key future business drivers such as the integration of battery storage and distributed generation resources.

• Assess the potential costs and benefits of increased transmission both internal and external to ERCOT and increase coordination with other power regions.
