EGU Rules Database Uses

Ground-truthing of IPM 2015 and 2020 base case output (emissions, emission rates, capacities, dispatch, import dependence)

Evaluation of different data sources for purposes of standard setting and compliance

Evaluation of the implications for stringency of control of different baseline years and different types of standards, e.g, input-based, output-based, cap and trade with rate equivalency

EGU Rules Database Uses (cont.)

Assessment of different constructions of CO2-equivalency

Understanding the emissions benefits of early actions under the Minnesota Renewable Energy Standard and EE law

Understanding the emissions benefits of other early actions

Calculating the impacts of imported power on total system emissions
