Selling surplus energy to a transmission system operator (TSO) is an important source of income for many operators of renewable energy systems.

It’s almost impossible to think of a business that doesn’t use electric motors. In industry, they power the manufacturing processes, and in virtually every commercial building they drive the systems that provide a comfortable working environment. Motors also use a lot of energy.

This makes energy efficiency of motors a key concern for every business owner and manager, says Julian Grant of Chauvin Arnoux.
