Reddit reviews Reliability Evaluation of Power Systems

All I've got for you a very dense textbook that my co-worker lent me:

Reliability Evaluation of Power Systems by Roy Billinton and Ronald N. Allan. Definitely not light reading, but my co-worker told me it is basically the Bible when it comes measuring, calculating, and understanding the reliability of electric generation, transmission, and distribution, from both an engineering and economic standpoint.

Probably not what you're looking for, but just thought I would throw it out there in case it struck your fancy.
