I don't believe Nymex officially has a platform for power. Last I heard they were trying to put it up on Globex, but with the intricacies of all the different strips, it just seems like a nightmare logistically.
Amerex just launched their energymatch platform which offers STP and if you choose Nymex as your exchange, the trades get submitted immediately for clearing.
