There is already a State-funded utility review and rate control organization with well-paid staff that the Governor could direct to explore the efficiencies and regulatory/rate structures of various consolidation and infrastructure configurations - It's the Alaska Public Utilities Commission (APUC). 
Unfortunately this has too often served as a source of well-paid Commission seats for the politically connected, rather than for the analytically competent.  The administration could add some real beef to the capacity of this Commission by taking some of the purely political appointees  out of it and replacing them analytically competent political appointees ..
This sort of public impact/public cost review has long been done here in AK before new hospitals could be built- Actually I'm a bit surprised it isn't already done for utilities as well..
