April 2005 - PJM Interconnection, a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of 12 states and the District of Columbia, announced the launch of the Generation Attributes Tracking System or GATS. The GATS tracks generation attributes and the ownership of the attributes as they are traded or used to meet government standards, such as renewables portfolio standards or fuel-source disclosure reporting. The GATS design was developed through collaboration with state utility regulators, state environmental protection offices, state energy offices, consumer advocates, electric market participants, environmental advocates and other stakeholders. The GATS system is owned and administered by PJM Environmental Information Services.
