## Summary

**Electricity & air emissions**
**The North American power grid**
**EPA data tools**

## Major Air Emissions from Power Generation

## Power Industry Resource Mix (1997)*

## Emission Rates:

**Oxides of Nitrogen (NO****x****)**

**Carbon Dioxide (CO****2****)**

**Data Source: E-GRID2000 v2.0                                                               Prepared 11/04/2002 by Art Diem USEPA 202-564-3525**

**Emission Rates:**
**Fossil vs. Wind (lb/MWh), 1998**

## The Integrated North American Power Grid

***Power flows don’t follow state lines!***

## Three Distinct Grids

## EPA Data Tools Support State & Local Programs

**E-GRID**
**Power Profiler**
**Displaced emissions ****	****	****	****	****analysis (“ADER”)**

## E-GRID: EPA’s Comprehensive Source of Electric Power Data

**Emissions profile (NO****X****, SO****2****, CO****2****, Hg)**
**(short) tons**
**input rate (lb/mmBtu)**
**output rate (lb/MWh)**
**Generation resource mix **
**percentage break-out by fuel type**
**Data aggregated to every level:**
**unit, plant, company, state, grid region, U.S. total**
**Includes 4600+ US plants, 2200+ companies**
**Integration of 23 federal data sources**

## E-GRID Methodology

**CEM-based emissions data overlaid on fuel-based estimates**
**Mercury (Hg) data limited to 450 coal-fired plants**
**CHP allocation formula:**
**thermal output discounted by 50%**
**emissions, fuel consumption reported for electricity only**
**Biomass assigned zero CO****2**** emissions**
**Generation from MSW split:**
**70% biomass/ 30% fossil**

## 1998 CO2 Emissions and Output Rates, by State

**1998 CO****2**** Emissions and Output Rates, by State**

## Slide 12

## E-GRID 1998 Resource Mixby NERC Region*

***U.S. portions only**

## Uses for E-GRID

**Consumer information disclosure/ ”green” power **
**Development of inventories, output-based standards **
**Implementation of renewable portfolio standards**
**Analysis of changing power markets**
**Analysis of cap & trade mechanisms**
**Public awareness of electric power emissions**

## Accessing E-GRID Data

**Two ways to view E-GRID data:**
**user-friendly data browser (install on PC)**
**35 spreadsheets in Excel workbook; ~1500 variables**
**Forthcoming E-GRID2002 edition featuring 2000 data expected late December 2002**
**download from EPA Website: *****www.epa.gov/airmarkets/egrid/***
**On-line access to E-GRID data expected early 2003**
***	******	******Questions/comments?:***

## Forthcoming: 

**Web-based calculator for businesses, individuals**
**Calculates consumer’s emissions and fuel mix**
**compares to national average**
**Provides info on energy alternatives**
**User provides:**
**zip code**
**distribution utility (from pull-down menu)**
**monthly electricity usage**
**	****	**

## Power Profiler (cont’d)

**Data based on E-GRID data for 27 grid “subregions”:**
**Expected  early 2003**

**Access via *****www.epa.gov/cleanenergy***

## Forthcoming: Average Displaced Emission Rates (ADER)

**Estimates emissions displaced by efficiency, clean energy technologies**
**CO****2****, NO****X****, SO****2****, Hg**
**region-specific, for 5 ****	****	****	****	****	****U.S. regions**
**time frames: 2005, 2010, ****	****	****	****	****	****2015, 2020**
**technology-specific estimates**
**ADER values generally below historic system averages**
**Preliminary results expected early 2003**

## ADER Technologies

**Residential energy efficiency**
**weatherization****	****	****-   programmable thermostat**
**heating****	****	****	****-   air conditioning**
**new homes (overall)**
**Commercial energy efficiency**
**tune-up****	****	****	****-   fans & motors**
**plant****	****	****	****-   equipment**
**lighting****	****	****	****-   overall**
**Clean energy supply, e.g.:**
**wind**
**PV**
**other **
**National (uniform change to load shape)**
