Electrical engineering services for this PV feasibility study evaluated multiple sites and supported selection of three locations for detailed analysis. The work included production modeling, utility rate analysis, electrical system assessments, coordination with a structural subconsultant, and development of a report outlining energy performance and financial savings, along with technical review of the County’s solar provider RFP.

Project Goals

As part of its ongoing commitment to sustainability and reducing energy use and cost, Henrico County contracted with 2RW to help it identify County facilities where PV installations could drive energy savings.

Services

2RW led a feasibility study to identify viable locations for PV installations. From a preliminary analysis of 18 locations, the County selected three sites (Libbie Mill Library, Western Government Center Parking Deck, and the Mental Health and Developmental Services East Center) for detailed study.

2RW’s services included:

  • Analysis of building age and roof and/or site area
  • Modeling of annual array production estimates to predict peak demand and annual utility cost savings
  • A utility rate study comparing cost savings under Dominion Energy’s available rate schedules
  • Assessment of each building’s electrical systems to identify required power system modifications
  • Management of a structural engineering sub-consultant that conducted site assessments
  • Development of a detailed report summarizing the energy and financial savings potential for each site
  • Technical review of an RFP the County developed to identify a solar provider

Results

The solar PV feasibility study identified three viable locations in Henrico County for PV installations (Libbie Mill Library, Western Government Center Parking Deck, and the Mental Health East Clinic) and summarized the energy and financial savings potential for each site. To date, Solar PV panels have been installed on Libbie Mill Library and Western Government Center Parking Deck.
