Ohio Consumers' Counsel Sues Defaulting Gas Supplier

LCG, Dec. 11, 2000--The Ohio Consumers' Counsel filed a lawsuit Friday charging D&L Gas Marketing, a natural gas supplier based in Youngstown, with breaching its contracts with more than 4,500 customers in the Columbia Gas of Ohio customer choice program.

In late July and early August, D&L sent a letter to each of its 4,500 customers giving notice that as of November 1 the company would withdraw as a natural gas supplier from the Columbia Gaschoice program. Customers, who had enrolled under a 12-month service contract, were given 90days to switch to another natural gas supplier or be returned to Columbia Gas at its higher regulatedrate.

But under the terms and conditions of D&L's contract, the company was allowed to terminate service with a customer only at the end of the initial 12-month contract term or if a customer failed to make payments, the Consumers' Counsel charged.

Customers of D&L had contracts with fixed rates between $0.37 per ccf and $0.48 per ccf.Customers who did not select another supplier were returned to Columbia Gas and were subject toits November 1 rate of $0.74 per ccf, the consumers advocate said.

"D&L's actions have caused financial harm to its customers. As the residential utility advocate the OCC is determined to see that all affected customers receive the compensation they deserve," saidRobert S. Tongren, the Ohio Consumers' Counsel.

"We cannot allow someone to jeopardize the economic democracy that this choice program hasprovided Ohio consumers," he added. "Too many people have worked too hard to make Ohio's program a national model. We are taking this action now to maintain the integrity of the choice program."
