The issue of PGW’s possible diversification is coming into focus just as Council is set to consider the city’s plans to partner with a developer to build a liquefied natural gas (LNG) facility at PGW’s Passyunk Plant. Under the agreement, Liberty Energy Trust would pay the costs to build the $60 million plant. PGW would get at least $1.35 million a year to operate it, reducing the need for rate increases. LNG is a liquid form of natural gas that is in demand primarily for power generation, often to replace dirtier fuel oil or diesel.
