The Town of Centreville continues its push to reduce carbon emissions by installing solar panels at its Waste Water Spray Irrigation facility. The one-megawatt solar project consists of two arrays totaling 4,172 solar panels across five acres of farm land. Over the next 20 years, the Town of Centreville’s solar system is expected to provide an estimated 1.3 million kWh annually, enough to offset more than 40 million pounds of CO2.
Centreville’s Power Purchase Agreement (PPA) with SolarCity enables the Town to save money on electricity without needing upfront capital. Through the PPA, Centreville buys power that the solar system generates at a lower rate than what they would have paid the local utility company. The system is projected to save residents over $1 million over 20 years. The arrays will also help defray the cost to operate the waste-water spray irrigation system, water treatment plants and other facilities owned by the town.
* Expected savings are estimates based on SolarCity’s solar power rates compared to current electricity usage at Centreville’s Waste Water Spray Irrigation facility, current utility power costs and predicted future utility power costs.
