[California Energy Commission Letterhead]

Distributed Generation (DG): Will DG impact air quality?
Presentation by University of California, Irvine

Place: Hearing Room A, Bonderson Building
901 P Street Sacramento Ca 95814
Date: September 27, 2004
Time: 1:00 p.m. to 2:30 p.m.

You are cordially invited to an informal presentation by researchers associated with the University of California, Irvine. The researchers will present a summary of the results of a project funded by the California Energy Commission under the Public Interest Energy Research (PIER) program. The goal of the effort is to determine whether installation of distributed generation throughout the South Coast Air Basin (SoCAB) could impact air quality.

The presentation will include three major parts: (1) development of DG implementation scenarios, (2) overview of the air quality model, and (3) presentation of air quality results. Details on how accurate characterization of emissions factors for each DG technology, likely spatial distributions, DG technology types and temporal profiles of DG use will be presented. Emissions of NOx, VOC, SOx, NH3 and particulate matter (PM) were included since these could affect ozone and PM forming potential in SoCAB. The air quality model that will be introduced includes 3-D spatial and temporal distributions of primary and secondary pollutant species in SoCAB that solves coupled, detailed mass transport, homogeneous, and heterogeneous atmospheric chemical reactions within the geometrical constraints of the basin. Results will be presented from the simulation of various DG implementation scenarios with different spatial allocation, duty cycle, and DG technology mix, which show different temporal and spatially distributed impacts on ozone, NOx and PM concentrations in SoCAB.

A draft agenda is as follows:

I     Introduction - Marla Mueller

II     Project Overview - Jack Brouwer (UCI)

III     DG Implementation Scenarios - Jack Brouwer (UCI)

IV    Air Quality Model Overview - Donald Dabdub (UCI)

V     Results for Potential Air Quality Impacts of DG in SoCAB - Donald Dabdub (UCI)
