Sept 1 (Reuters) - Natural gas pipeline operator TransCanada
Corp TRP.TO said on Tuesday the U.S. Federal Energy Regulatory
Commission has allowed it to reclassify some 1.1 billion cubic
feet of gas in storage as "working gas" which can be burned at
any time for heating or electrical generation.
Previously, the gas was classified as "base gas" supply,
which must be left underground to maintain a certain level of
operational pressure in a gas cavern.
