This article is underestimating also how creative can people can become under stressful situations. For example, converting car engines as power generators, fixing these High voltage transformers, etc. People adapt, they will build power generators based on whatever they find, industries will shift to make photovoltaic panels and electric production will become local, etc. Yes it's 90% of people dying if there is no electricity and everybody stays home waiting to die. 1 billion people in the world live without electricity. The solar flares are a minor risk compared to the main actual risk (war or sabotage), if there is a war, no matter how many High voltage transformers you have in stock, they are going to be destroyed.
