The North American Electric Reliability Corporation (NERC) is a non-profit organization that is responsible for ensuring the reliability and security of the North American electricity grid. With the increasing demand for power generation, it is crucial to maintain the power system’s reliability and efficiency.
NERC plays a vital role in the power industry and is best known for its Generating Availability Data System (GADS), which provides essential data for grid analysis.
In this article, we will highlight the significance of NERC and GADS to the power industry, the reporting requirements, and the benefits of complying with these regulations.
What is NERC?
NERC is an independent organization that oversees the reliability and security of the bulk power system in North America. NERC develops and enforces mandatory reliability standards that all utilities must follow, ensuring the safety, reliability, and security of the electric grid.
NERC comprises six regional reliability councils. These councils control almost all of the electricity supply in the U.S. and Canada.
The 6 NERC Reliability Councils Include:
- Midwest Reliability Organization
- ReliabilityFirst
- Northeast Power Coordinating Council
- SERC Reliability Corporation
- Western Electric Coordinating Council
- Texas Reliability Entity
NERC’s mission is to ensure that the highest level of system reliability is maintained to protect public safety, the economy, and the environment.
The Difference Between NERC & FERC
The North American Electric Reliability Corporation (NERC) is a non-profit authority responsible for ensuring the reliability and security of North America’s bulk power system, setting and enforcing reliability standards.
The Federal Energy Regulatory Commission (FERC) is a U.S. government agency regulating interstate electricity, natural gas, and oil transmission, as well as hydroelectric projects, focusing on fair pricing and dispute resolution.
While NERC focuses on power system reliability and security, FERC regulates energy transmission and market rates, both playing crucial roles in maintaining a stable electric grid.
What is GADS?
The Generating Availability Data System (GADS) is a program developed by NERC to collect, manage, and analyze the power system’s performance and reliability data.
Mandatory GADS was introduced in 2012 and expanded in 2013 to include larger power generators
GADS data provides critical information that helps identify trends, track equipment availability, evaluate power system adequacy, and optimize the system’s performance. Information collected by GADS includes energy production, forced outages, planned outages, and deratings.
NERC GADS Reporting Requirements
NERC has established specific reporting requirements for utilities that must be adhered to under the GADS program. Utilities must regularly report data on the availability and performance of their generating units, thermal fuels, and environmental systems.
Energy production and outage data are recorded, including planned, forced, and derated outages along with environmental and fuel-related data.
The NERC GADS reports provide a valuable source of data for system performance analysis and monitoring.
Key Components of GADS Reporting
GADS reporting involves three essential components:
- Design – equipment descriptions such as manufacturers, number of boiler feedwater pumps, steam turbine MW rating, etc.
- Performance – summaries of generation produced, fuels units, start ups, etc.
- Event – description of equipment failures such as when the event started/ended, type of outage (forced, maintenance, planned), etc.
Utilities collect data on their generating units and power plants, which is then organized and validated before being submitted to NERC using their Data Reporting Instructions.
The data validation process is critical to ensure the accuracy and quality of the reports. Utilities use sophisticated data management software to collect, organize, and submit this data, ensuring that the reports comply with NERC’s standards.
NERC GADS Compliance and Penalties
Failure to comply with regulations can lead to significant penalties, including fines, orders to correct significant deficiencies, and financial sanctions.
Utilities can also damage their reputation and face regulatory scrutiny by not following proper reporting procedures.
Proper GADS reporting provides benefits such as improved performance analysis, outage planning, and equipment maintenance. Compliance with these regulations demonstrates a commitment to transparent regulatory compliance, and, most importantly, a reliable energy supply for all levels of society.
How to gather GADS data
Most major power generators are using automated software to save time, eliminate errors, and report accurate data to NERC to avoid penalties.
