Hydro Electric Development Corporation (Hedcor) connected the historic 4.3 MW Asin hydroelectric power plants to the NPC System in Baguio City last July 19, 2002.
This connection will facilitate the sale of power to Pampanga-based distributor, San Fernando Electric

CAPTION FOR PHOTOS: The connection of the Asin hydro electric power plants to NPC was made
possible by a new P16M substation and 2 kilometer transmission line (NPC 3T standard) which
Hedcor constructed at its own cost. It includes a state- of-the-art substation protection system and
69KV/23KV SF6 power circuit breakers with the latest technology in electronic metering systems.
