Four hearings on a proposed rate plan for National Fuel Gas Co. that would freeze delivery rates through most of next year, while refunding $5.5 million to residential and commercial customers, will be held on Feb. 24 and Feb. 25 by the state Public Service Commission.

The first two hearings will start at 3 p.m. and at 6:30 p.m. on Feb. 24 at the Buffalo and Erie County Public Library auditorium at 1 Lafayette Square. The third and fourth will be held at 3 p.m. and at 6:30 p.m. on Feb. 25 at the Niagara Falls Public Library auditorium, 1425 Main St.

The joint proposal worked out by the Amherst energy company, the PSC staff and other interested parties, also would provide $2 million in weatherization and furnace replacement funding for low-income customers. The proposal still must be approved by the PSC, which could change any of the terms of the proposed deal.
