From what I gathered in reading the three articles there's a state code that mandates that homes must be hooked up to the electrical grid. With out seeing the law or it's history (e.g. when it was mandated), it's difficult to say if it's malice on the part of utilities or just a poorly worded law from 50 years ago.
Electricity is regulated, like water, because it's something people have a hard time living without in modern society. It's perfectly reasonable for the state to mandate that properties have power as a protection for tenants.
It certainly sounds like the power company is doing nothing to accommodate those who would like power by having policies in place for reporting solar hookups to protect linemen or offering bi-directional meters to avoid billing irregularities, but there's no evidence presented to support the assertion that they lobbied to prevent solar.
