This market and the Medium Voltage Equipment required are typically used for utility intertie applications. The most active market is in Photo Voltaic (PV) with direct conversion (Sunlight to electricity). Typical sized PV installations are 1, 3, 20, and 50 MW. Utility voltages are commonly 15kV, 25.5 (27kV Class) and 34.5kV (38kV Class).

Other renewable energy sources are wind, geothermal, farm waste, and wave motion. One 1200A Switchgear assembly can be used up to about 25 Mw at 13,800V.

Note that many PV and Wind facilities are requiring batteries to supplement the power output and assist with the quality of the utility power.
