Generation Attribute Tracking System (GATS)
|Generation Attribute Tracking System (GATS)|
The Generation Attribute Tracking System (GATS) provides information about how megawatt-hours of electricity are generated. The data are used to meet the information disclosure requirements of states with fuel mix and emissions disclosure requirements or that have renewable portfolio standard requirements. Participation in GATS is by paid subscription.
The GATS database contains information for each individual generation unit. It creates generator-specific electronic certificates that identify the generation attributes necessary for electricity suppliers to satisfy state policies and to document claims made about “green” power. Data in the GATS include: megawatt-hours produced, emissions data (primarily from the U.S. Environmental Protection Agency and supplemented from other sources), fuel source, location, state program qualification and ownership of attributes for each megawatt-hour tracked. The attributes or characteristics of the generation are recorded into the database as an electronic certificate after the electricity is produced. There is one certificate with a unique serial number identifying the attributes of the generation for each megawatt-hour produced. 
PJM Environmental Information Services, Inc. (PJM EIS) owns and administers the Generation Attribute Tracking System (GATS).
PJM EIS is a wholly-owned subsidiary of PJM Technologies, Inc. PJM EIS was formed to provide environmental and emissions attributes reporting and tracking services to its subscribers in support of renewable portfolio standards and other information disclosure requirements that may be implemented by government agencies.
Products and Services
GATS fulfills four general market needs for collecting and tracking generation attribute data:
Information disclosure by load serving entities to retail customers
- Some states require electricity suppliers periodically (quarterly, semi-annually or annually) to inform their customers about the fuel source, emissions and other characteristics of the electricity supplied.
Renewable portfolio standards (also known as clean energy portfolio standards)
- A renewable portfolio standard requires an electricity supplier to include a minimum percentage of electricity produced by renewable or environmentally preferred generation sources in its mix of electricity supplied to retail customers.
Emissions/generation performance standard obligations of electricity suppliers
- An emissions performance standard or generation performance standard prohibits an electricity supplier from exceeding a maximum threshold of specific emissions in its mix of electricity resources supplied to customers.
