Mr. David Paylor
Director Virginia Department of Environmental Quality
629 East Main Street Richmond, VA 23219

Dear Mr. Paylor:

The purpose of this letter is to inform you and document that Prince William County (General Government) will be implementing a three percent (3%) wind energy purchase as a voluntary measure to be included in the State Implementation Plan (SIP) for Air Quality. We hope this purchase will help the Washington Metropolitan region achieve the new eight-hour
standard for ozone.

The County plans on implementing this program for the next three years, with an
estimated 750,000 KWH per year purchase. This commitment is in response to the Metropolitan Washington Council of Governments Board of Directors' and the Metropolitan Washington Air Quality Committees ' requests to have local jurisdictions implement voluntary measures to help meet the Federal air standards for our region in 2009-2010.

This purchase will be done through a regional purchase of wind energy through the Virginia Energy Purchasing Governmental Association (VEPGA). If you have any questions
or need additional information, please contact Mr. Matt Groff from our Department of Public Works at (703) 792-7183 or Mr. Rick Canizales from our Department of Transportation at (703) 792-5985.

# Methods used to Quantify Reductions in Electricity Consumption

Estimating Ozone Season Electricity Reductions

The calculation of energy reductions proceed s in two steps: calculation of annual electricity reductions and calculation of ozone seas on electricity reductions.



# Annual Electricity Reductions
The annual reductions in electricity use are described below in the notes on each jurisdiction’s approach.



# Ozone Season Electricity Reductions
The annual kWh savings are then used to estimate ozone season kWh savings.

First, the kWh savings for each measure are cl assified into the following categories: air conditioning reductions, lighting reductions, and reductions fro m other measures. In the following notation, the subscripts a, l, and o are used to refer to these categories, respectively. The total annual reductions in each category are given by ∆ kWh a 

## , ∆ kWh l 

## , and ∆ kWh o 

## .

As described below in more detail, the annual ∆ kWh estimates are generally developed using engineering methods. The resulting estimates are taken to represent the performance of the energy efficiency meas ures when they are newly installed. The resulting ∆ kWh estimates are assumed to decreas e over time. A simple discounting formula serves as a proxy for a variety of complex factors that will decrease the performance of energy efficiency measures ove r time: It is assumed that the performance will decrease by 15% per year. 1



## Using a building simulation model and data from the Commercial Buildings Energy Consumption Survey of the U.S. Energy Info rmation Administration, model time-profiles were developed for each of these three categories of efficiency measures. 2 

## This procedure yields a set of three factors f a 

## , f l 

## , and f o 

## that represent the frac tion of the annual savings that occur in the ozone seas on, for each category.

From these values, the hourly ozone-s eason kWh reductions for each category, O 3 

## ∆ kWh a 

## , O 3 

## ∆ kWh l 

## , and O 3 

## ∆ kWh o 

## are given straightforwardly by

# Notes on the Energy Savings Estimates for Each Jurisdiction

Arlington County, VA

Arlington County has been investing in energy upgrades for its government facilities for some time. Data is available on the impacts of the investments for the period from 2002 to 2005. Initial estimates were developed usi ng energy savings data and cost data for the energy retrofits from the program history. NREL developed estimates of future savings were developed from detailed descriptions of measures planned for future program investments. Each of the specific measur es described falls into one of the three categories described above. The ∆ kWh estimates for each measure were developed using engineering data from manufacturer’s specifications and other sources.

Baseline. Arlington County used the existing pe rformance of the building as the baseline figure. The estimation of ∆ kWh assumes that the existing performance of the buildings would have persisted in the ab sence of Arlington’s energy conservation program, and that the SIP baseline did not in corporate the impacts of the program. The county has provided a budget line-item for th at program to make energy efficiency investments that would not have been made in the absence of the program.

Performance with Efficiency Measures in Place. For measures put in service between 2002 and 2005, ex post performance is based on measured data. The energy performance estimates for future measures were developed using engineering estimates, e.g. from manufacturer specifications.

Conservative assumptions for savings are use d, and the buildings targeted here will not be mothballed, replaced, or substantively change d in intensity of occupancy or use. The use of the Arlington building inventory is some what fluid, but the buildings targeted by the included measures will remain in use for the foreseeable future.

### Source: Excerpted from supplemental data provided by John Morill, Arlington County, November 2006.

## Note: Because we are not certain of the da tes, we discounted the measures undertaken before 2006. We have assumed that measures undertaken before January 1, 2003 are included in the SIP baseline and therefore not eligible. For Arlington, assuming that the measures are undertaken evenly over time, 20 pe rcent would have been in service before 2003. To be conservative, we have excl uded 30% of the total in each category.
