What is GATS?
• GATS - a regional environmental registry and information system that will track the environmental and fuel attributes of generation.
• The system will:• assist LSEs in their compliance with applicable
emissions and fuel disclosure requirements and with state-level Renewable Portfolio Standard (RPS) regulation or renewable policy
• enable voluntary bilateral markets and marketing claims for renewables.
• provide state agencies with reporting and verification• provide renewable generators with a means to
monetize their renewable attributes and qualification

Needs of the PJM States / Market
• PJM initiated the GATS project in response to state regulatory commission inquiries and effected stakeholders
- Fuel Mix and Emissions Disclosure
• Delaware: fuel mix • Pennsylvania: fuel mix• Maryland: fuel mix and emissions• New Jersey: fuel mix and emissions• Ohio: fuel mix and emissions• Virginia: fuel mix and emissions• Illinois: fuel mix and emissions• District of Columbia: fuel mix and emissions
- Renewable Portfolio Standards• New Jersey: began in 2004.• Maryland: requirements in effect in 2006• Pennsylvania: requirements in effect in 2007• District of Columbia: requirements in effect in 2007• Delaware: requirements in effect in 2007

• All MWhs of PJM generation are tracked.• A certificate market separate from energy is enabled for
renewable generation.- Certificates (i.e., credits) traded separate from energy- Certificates can have different value depending on their attributes
(e.g., fuel type, location, date of generation, etc). • It is a single information system that will support a range of
reporting, verification, and compliance requirements (e.g., disclosure, RPS, voluntary retail markets, etc).
• It is a regional system that will enable PJM states and market participants to support varying needs and priorities.
• A system that is flexible enough to meet evolving state requirements.
Design Overview
6©2008 PJM EIS
Design Overview
• GATS is designed to be policy-neutral to the greatest extent possible
• The system accommodates:- banking certificates to accommodate varying certificate life spans as
determined by state policy or regulation- enabling varying state programs and their definitions of preferred
attributes:- wind, solar, biomass, etc.- energy efficiency- waste coal- pumped storage generation
- moving certificates to non-LSEs for bilateral voluntary markets, i.e. direct sales to retail entities
- a bulletin board to facilitate bilateral trades- behind the meter generation, imports and exports

Each MWh is given a unique electronic certificate This certificate may contain any information relevant to market participants and capable of being tracked by GATS.
- Certificates’ data will be compiled using PJM generation and publicly available data from EPA and EIA.
- Where data do not exist or are faulty, generators may choose to update their information based on agreed upon best practices.
- Default assumptions will be developed as a last resort for generators with faulty or no data who choose not to update their information.

Certificate Creation
• Account Holder Review Period spans from the 10th business day to the day before certificates are created
• Certificates created monthly, on the last business day of the following month

• Emissions data tracked in GATS:- Carbon dioxide- Nitrogen oxides- Sulfur dioxide
• Emissions data comes from a hierarchy of sources:1) Entered by the generation owner during the Account Holder Review Period
(in lbs)2) Emission rate (lbs/MWh) calculated by PJM-EIS using EPA unit-level
annual emissions for generators in the Acid Rain Program. Preliminary 2007 date is currently available.
3) EPA Emissions & Generation Resource Integrated Database (eGRID) emission rate (lbs/MWh). eGRID2006 Version 2.1 contains 2004 data.
4) Fuel Type Default (lbs/MWh)

Certificate Trading Period
• Certificates created monthly to increase flexibility and accommodate differing state reporting periods
• Preliminary reports issued each quarter• Annual settlement in late February for the preceding calendar year• RPS-eligible certificates can be “banked” any time prior to the
annual settlement date so that they can continue to be traded.

Enhancements to Support RGGI
18©2008 PJM EIS
• New Generator Attributes- RGGI-affected unit- Unaffected small fossil fuel-fire unit- RGGI-region unit
• Infer net “imports” into RGGI portion of PJM- “Imports” = difference between load and generation in the RGGI portion of PJM- Environmental attributes of net “imports” will be based on non-RGGI PJM residual mix
• New Reports- Total PJM load subject to RGGI- Total PJM generation in RGGI-region - “RGGI emissions mix”- “RGGI residual mix”- “Unaffected small fossil fuel-fired RGGI-region unit emissions mix”
• For details on these calculations refer to:- “Initial Report of the RGGI Emissions Leakage Multi-State Staff Working Group” dated
3/14/2007: http://www.rggi.org/docs/il_report_final_3_14_07.pdf • Enhancements will be implemented by end of 2008
