Utility regulators issued a request for proposals last month following a state law that gave them power to execute a contract to address wintertime shortages of natural gas.
The new law allows the Maine Public Utilities Commission to have ratepayers fund up to $75 million a year to fund liquefied natural gas storage facilities. It's an expansion on a 2013 energy bill that encouraged an expansion of pipeline capacity.
The original deadline for proposals was late next week. The new deadline is Nov. 4. Commission Chairman Mark Vannoy says the panel looks forward to evaluating proposals as it seeks solutions to Maine and New England's "regional energy challenges."
