Sudberry Properties of San Diego has installed six electric vehicle charging stations at its Civita master-planned community in Mission Valley, in a partnership with NRG eVgo, a subsidiary of Houston-based NRG Energy Inc.

The charging stations, on Westside Drive and Civita Boulevard, provide 12 to 25 miles of charge per hour, Sudberry officials said. The developer has six additional charging stations scheduled for installation at its West Park apartment community, slated to open in late summer at Civita.

Financial terms of the partnership were not disclosed. Officials said the Civita charging stations are also accessible by the car-sharing service car2go, which has 380 all-electric vehicles in its San Diego fleet.

The developer is also collaborating with San Diego Gas & Electric to make Civita a “smart grid community,” with the use of fuel cell, solar and other technologies geared toward boosting energy efficiency, Sudberry Senior Vice President Marco Sessa said.

Built on the site of a former quarry, plans for the 230-acre Civita call for more than 4,700 houses and apartments in several phases and configurations, with parks, civic, retail and other commercial elements. Several homes and apartments have already been developed by Sudberry and its partner builders.
