Director

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 proceeds in two steps: calculation of annual 

electricity reductions and calculation of ozone season 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 classified into the following categories: air 

conditioning reductions, lighting reductions, and reductions from 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 ∆kWha, ∆kWhl, 

and ∆kWho. 

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 measures when they are newly installed. The 

resulting ∆kWh estimates are assumed to decrease 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 over 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 Information Administration, model time-profiles 

were developed for each of these three categories of efficiency measures.2

 This procedure 

yields a set of three factors fa, fl, and fo that represent the fraction of the annual savings 

that occur in the ozone season, for each category. 

From these values, the hourly ozone-season kWh reductions for each category, O3∆kWha, 

O3∆kWhl, and O3∆kWho are given straightforwardly by

The ozone season kWh reductions given by equations [1]-[3] are then multiplied by the 

ozone season displaced emissions factor calculator used to estimate the ozone season 

NOx reductions.

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 using 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 measures 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 performance of the building as the 

baseline figure. The estimation of ∆kWh assumes that the existing performance of the 

buildings would have persisted in the absence of Arlington’s energy conservation 

program, and that the SIP baseline did not incorporate the impacts of the program. The 

county has provided a budget line-item for that 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 used, and the buildings targeted here will not 

be mothballed, replaced, or substantively changed in intensity of occupancy or use. The 

use of the Arlington building inventory is somewhat fluid, but the buildings targeted by 

the included measures will remain in use for the foreseeable future.

Note: Because we are not certain of the dates, 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 percent would have been in service before 

2003. To be conservative, we have excluded 30% of the total in each category.
