I don't know what the electricity costs of the TMT will be, but comparisons with the Keck observatory are almost certainly invalid. The Keck has two domes and telescopes, the TMT will have one although it will be larger. The TMT will have a smaller surface area to volume ratio compared to the Keck domes plus bigger and more massive equipment that will have a much longer thermal cycle time. I don't see how anyone can predict those costs at this time.
