“UPS: for When the Grid Goes Down”. Power provided by the grid is more than up to the job of powering lights and motors, but when you want to power tele- and data communications equipment, or if you are manufacturing microelectronics, you need to take the power that comes from the utility and clean it up. The right kind of UPS (uninterruptible power supply) not only can keep the equipment running during a power failure, it can also provide a clean source of power.

City Promotes Economic Development with High-Reliability Electric Power

Bookmark and Share

The importance of reliable, high-quality electric power is increasingly being recognized by utility customers. It fosters economic development and enhances the attractiveness of a service area to “new technology” businesses.

For these reasons, the City of Danville, Virginia, sought a high-reliability distribution system to serve a new 330-acre high-technology Cyber Park anchored by the Institute for Advanced Learning and Research and the Regional Center for Applied Technology and Training. Danville had just started an aggressive economic development initiative and understood the advantages of promoting a unique set of utility services to differentiate the Cyber Park from other regional parks. Dependable switchgear would be needed, as well as engineering and installation support services. Danville Power & Light (DP&L) owned and operated by the City of Danville, serves approximately 42,000 customers in a 500-square-mile service territory covering portions of a three-county area.
