Even if the planet could heat itself (which is likely), there is a damn good chance that evacuation would happen. If there is any solar ionisation plants used for power, problems will increase dramatically.
I'm currently in a lab where we work with machinery and power networks. From what I've found out, some generators are ideal for steady loads and some are more suited for peak times. Nuclear power costs about the same whether the station is producing power or not, so nuclear power plants produce power around the clock, while coal power plants are usually run during the day to handle the peak power requirements of the grid. So with that in mind, that has me thinking back to one of the EU books.
In the book Han is nearly hit by a giant machine that uses heat to drill through the polar ice of Coruscant. The primary reason for this is to provide drinking water to the people of Coruscant, but in water is the key to fusion power: Deuterium. If the water being harvested was processed to extract the deuterium, it would provide a nearly constant amount of fuel to feed the power grid of Coruscant. And unlike our own real world reactors, Coruscant would remain about the same, load wise, as the planet rotates instead of having continents that draw power during the day and then drop the load at night. If there was a need for more, solar plants could come online.
The reason I say all this is that if Coruscant does lose its star, it might not be drastically hit, power wise, except when the shield come online. That might cause brownouts, but whatever. I would imagine that would be the least of the average citizen's concerns in that case.
