Selecting Substation Medium-Voltage Switchgear: GIS vs. AIS

Understanding differences between GIS and AIS in five points

BY GAETAN DJENANE, Schneider Electric, Inc.

Many considerations must be taken into account before selecting the electrical medium-voltage (MV) switchgear that best meets a user’s needs. From a management perspective, considerations include the purchase price, the life expectancy of the switchgear, and the size of the equipment, the amount of time to install and commission the gear, worker safety, outage risk, maintenance, and reliability. From an...

New data suggests real-time pricing can help customers save money

Most utility customers now pay an average price for electricity that changes little (if at all) over the course of the year. Average, flat-rate, real-time pricing is akin to a form of insurance, where a premium is paid to hedge against market volatility and price spikes. Yet this approach misses...
