It's largely forest fires and regulation. Electricity prices are regulated by the state, and at the same time they mandate certain green energy goals. To hit these goals, electric companies have to ignore infrastructure to build renewable energy sources. If the infrastructure gets too old, it risks starting a fire, which could cost the company billions. When the state sees them lose money after a fire, the state lets them raise prices. It is a very silly cycle which could be ended by either removing green energy goals so they could improve infrastructure, and to not hold electric companies directly liable for all damage from a fire.
