History Historically many Councils operated coal gas operations, with LP reticulation to consumers. Several factors led to the eventual demise of this industry… The overall inefficiency of the gas production process. Lack of reinvestment in the LP networks. Increasing competition from electricity. Discovery of natural gas around Taranaki in the 1960’s. A few bottled gas operations remain in areas where gas is not reticulated.
