Emissions Quantification Tool

New online tool helps quantify emissions impacts on smart grid projects

The Emissions Quantification Tool (EQT) is an online calculator that is used to estimate the NOx, SOx and CO2 repercussions of smart grid infrastructure investments. The EQT uses a standardized methodology to estimate pollutant emissions reductions that can be realized by implementing some smart grid projects. The EQT estimates the impacts of a range smart grid projects, includes quantitative details about each project, and reflects regional differences regarding the effects of displacing fossil fuel generation. The EQT enables users to consider potential benefit streams for smart grid projects, articulate project impacts, and quickly screen alternatives.

As part of its efforts to quantify benefits from the smart grid, the US Department of Energy's Office of Electricity OE's Smart Grid Research and Development Program tasked Pacific Northwest National Laboratory (PNNL) to develop an estimate of the potential energy and emissions benefits that can result from deployment of the smart grid.

PNNL's 2010 analysis, "The Smart Grid: An Estimation of The Energy and CO2 Benefits," articulated mechanisms by which the smart grid can reduce the energy use and carbon impacts associated with electricity generation and delivery. That analysis quantified the carbon footprint reducing benefits of some smart grid elements, introducing a third way to quantify smart grid improvements alongside the twin pillars of improved reliability and reduced costs. The report identified both direct and indirect benefits, and was careful to identify inclusion and exclusion to avoid double counting.

The EQT was implemented by PNNL's Electricity Infrastructure and Buildings Division, which delivers advanced research concepts and innovations to improve the performance of the nation's power systems, enhance its security and position the grid as a central asset for national strategic imperatives such as increased domestic energy content and management of carbon emission.
