The Connecticut Department of Energy and Environmental Protection recently invited RAP senior associate Dave Farnsworth and senior advisor Dave Lamont to conduct a workshop exploring the capabilities of NEPOOL’s Generation Information Systems (GIS) and PJM’s Generation Attribute Tracking Systems (GATS) to track emissions associated with energy consumed in the region. As noted in RAP’s report, “Tracking Emissions Associated with Energy Serving Load in the Regional Greenhouse Gas Initiative (RGGI) States – a Feasibility Study,” both tracking systems have the capacity to account not only for the megawatt hours of energy consumed in the RGGI region, but also characteristics of that energy, including related CO2 emissions. While discussing various implementation challenges that stakeholders can expect related to data quality, regulator access, and system coordination, the presenters emphasize that GATS and GIS should not be overlooked as the tools most readily available to RGGI participating states for tracking emissions associated with energy imports into the RGGI region.
