U.S. Rep. Josh Riley is asking state regulators to compel NYSEG to disclose how many customers were affected by billing errors tied to incorrect temperature data and how much they were charged.
NYSEG has acknowledged that incorrect temperature information affected certain billing calculations between Feb. 19 and April 11, 2026. Some Upstate customers later received adjustments that added charges to their bills, according to Riley's office.
Riley filed a motion to compel the information as part of the utility's pending rate case before the New York Public Service Commission. NYSEG is seeking approval for rate increases worth hundreds of millions of dollars, the congressman's office said.
Motion seeks scope and cost of errors
The Ithaca-area congressman wants NYSEG to say how many ratepayers were affected, how many were overcharged or undercharged, when the company discovered the problem and how much the resulting adjustments will cost customers.
His motion also asks NYSEG to explain the legal basis for adding charges to customer bills after an error by the company. Riley argued that the information is relevant to the commission's review of whether the utility's proposed rates and charges are just and reasonable.
Riley said unpredictable corrections can create significant hardship for households already struggling to manage utility costs. He also questioned whether NYSEG knew about the temperature-data problem before it was reported publicly or discovered it only after news coverage brought attention to the issue.
NYSEG says issue has been resolved
NYSEG told the commission that the billing issue had been resolved and opposed providing the requested information, according to Riley's filing.
The company has not publicly identified how many customers received incorrect bills, how many will face additional charges or the total value of the adjustments, Riley's office said.
The motion now awaits action in the Public Service Commission rate proceeding. A ruling could determine whether NYSEG must provide the requested billing-error records as regulators weigh the company's rate request.
