1 PETER CIBOROWSKI JANUARY 13, 2012 EGU Rules Database

2 Summary of Data Held in ‘EGU Database.xlsx’ Emissions Emission rates  Input-based  Output-based Energy input to generation Net generation Generating capacity Heat rates EGU population Sector-level comparative emission and energy input to generation data Sector-level energy balance Import emission rates

3 Emissions Data In-State Emissions Facility-level tonsCO 2 (fossil, biogenic), emissions GHGs, SO 2, NO x, Hg Facility-level emission rates  Input-basedlb/MMBtufossil CO 2, GHGs, SO 2, NO x  Output-basedlb/MWHfossil CO 2, GHGs, SO 2, NO x Sector-level tons CO 2 (fossil, biogenic), emissions GHGs, SO 2, NO x, Hg Out-of-State Emissions Sector-level lb/MWH CO 2, SO 2, NO x emission rates

4 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

5 EGU Rules Database Uses (cont.) Assessment of different constructions of CO 2 - 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
