As the sales of consumer electric vehicles (EV’s) continue to rise in Nevada, there is a growing demand for EV chargers, especially residential electric vehicle chargers (ResEVC’s). This increasing number of ResEVC’s, whether in existing homes or new construction, necessitates changes in NV Energy's forecasting and design methods to accommodate the expected increase in electrical load.
To proactively address the anticipated load increase from ResEVC’s and minimize the need for future facility upgrades, NV Energy will begin accounting for a minimum of one (1) EV charger per home (7.24 kVA) in the load calculation and transformer sizing for all new detached homes and attached townhome projects.
These changes will be effective for all single-family residences and other residential projects where the ResEVC installation shares a common meter with the customer’s residential unit submitted beginning January 1, 2024.
To facilitate the reduction of upfront cost associated with EV charging installations, NV Energy's recent filing in Docket No. 22-09006 proposed and received approval for an "EV Allowance Adder." The EV Allowance Adder assumes the installation of a dedicated breaker position in the electrical service panel and circuit to a 240 V outlet in the intended charger location. Developers will continue to be eligible to receive this adder when the project application indicates their plan to equip residences with EV charging "make-ready" equipment.
NV Energy will account EV charger load regardless of the developer’s intent to equip residences with EV charging "make-ready" equipment as a part of the initial build.
Please contact our New Development Center, at 702-402-8400 for Southern Nevada projects or 775-834-7873 for Northern Nevada project, with any questions about how the EV charger load and EV Allowance Adder will be applied to your project.
