The new transmission line is expected to address the inadequate electricity supply in the southern region of the country.

EGAT’s new power line will run from Bang Saphan district, Prachuap Khiri Khan, to Surat Thani and Phuket to address the growing demand for energy, reported Bangkok Post.

Electricity Generating Authority of Thailand governor Sutat Patmasiriwat said, "If the board approves the investment according to our target, the new high-voltage transmission line will be in service around 2019."

The daily average demand for electricity in the south is 2,115MW to 2,185MW, but only 1,692MW is produced in the region. To meet the requirement additional supplies are received from the central region.

The authority is also planning to set up an 800MW coal-fired power plant in Krabi, while its subsidiary is discussing with energy regulators about license renewal for its 800MW Khanom power plant.
