Ok had to think for a sec. There's this guy in the Underground Paths...one of the two. After you get the electricity back on go through the underground paths and talk to this bald guy. Make sure you have a RageCandyBar from Mahogany. He gives you explosion for it. Pretty sure its the Celadon Underground Path.

This should help... TM 64 (Explosion) - Buy Ragecandybar at Mahogany, exchange with guy in underground path between Cerulean and Vermillion
one underground path goes from celadon to viridian. there is a second path, but it is permanently closed.
