ALBANY, N.Y. (AP) — One of the state's largest independent suppliers of electricity and gas for residential customers has agreed to refund nearly $1 million to resolve complaints about its billing practices.

Gov. Andrew Cuomo announced Monday that Texas-based Ambit Energy will issue $950,700 in refunds to 1,566 customers after an investigation by the state. About half of those customers live in central and eastern New York.

The state investigation began after complaints about Ambit's customer disclosure statements and renewal notices, particularly for customers who were moved from a guaranteed-savings plan into a variable rate plan charging significantly more.

Also Monday, AARP called on state regulators to investigate unfair energy pricing. It cited federal data showing that New York's independent energy service companies charged the highest residential electric prices in the nation last year.
