The Grid segment offers products and services that enable electric utilities, industrial facilities, and traditional and renewable energy project developers to connect, transmit, and distribute power under the Gridtec Solutions brand.

It provides transmission planning services, which identify power grid congestion, poor power quality, and other risks; grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems; D-VAR systems used for controlling power flow and voltage in the AC transmission system; actiVAR system, a fast-switching medium-voltage reactive compensation solution; armorVAR system installed for reactive compensation, power factor correction, loss reduction, utility bill savings, and mitigation of common power quality concerns related to power converter-based generation and load devices; D-VAR volt var optimization (VVO) that serves the distribution power grid market.

This segment also offers ship protection systems, which reduce a vessel’s magnetic signature; power management, power generation systems, and propulsion motors and power generators; and transformers and rectifiers; and REG systems used in a ring or loop configuration to interconnect nearby urban substations.

The Wind segment designs wind turbine systems and licenses these designs to third parties under the Windtec Solutions brand.
