It happened on January 3, 2012. At the time, Mr. McGillicuddy was living in Leith, on the outskirts of Edinburgh. He was all by himself in his tidy flat, eating his tea, when the storm began to batter the Scottish capital: Gusts of 100 miles per hour were blasting through the streets in the suburbs, while the narrow closes of the city’s Old Town were tormented by the roaring storm. The wind tossed through the air, cutting off electricity lines and damaging infrastructure. The lights went out, and many homes were left without power. Mr. McGillicuddy shivered due to the cold. It was only then that he realized just how important electricity was to him.

SSE plc and Scottish Power, an Iberdrola subsidiary, are among the two main utilities providing power to Edinburgh residents. Iberdrola and SSE are included in the 2018 ranking of the largest electric utilities worldwide. E.ON, headquartered Germany, reached sales of a approximately 35.1 billion U.S. dollars while Exelon was ranked as the leading U.S.-based electric utility company in terms of sales.
