The power company wants to cut corners. The government wants to prevent that. So there is constant lawfare between governments and highly regulated companies, with neither really caring if it leaves the customer out of pocket (since regulators can blame the bills on the company).
The company outsmarts the regulators so the regulators carpet bomb them with so much regulation that they hope it will plug all the loopholes. The incentives between them are simply too far apart. And with inbuilt market failures (due to it being a monoppoly) you don't have effective market mechanisms that allow the government to just set basic safety standards and get out of the way.
It's closer to the USSR than social democracy. http://highered.blogspot.com/2009/01/well-intentioned-commis...
