ALBANY (AP) - New York Attorney General Andrew Cuomo says Xcel Energy Inc. has agreed to disclose risks to investors from its stake in coal-burning power plants and any related liability from global warming, lawsuits and new regulations or laws.

Cuomo says coal plants can significantly contribute to climate change, "and investors have the right to know all the associated risks."

Cuomo said in September he was investigating Xcel, AES Corp., Dominion Resources Inc., Dynegy Inc. and Peabody Energy Corp. He said Wednesday the Xcel agreement sets a precedent. Cuomo spokesman Alex Detrick says negotiations are under way with the other four companies subpoenaed along with Xcel.

Minneapolis-based Xcel President Dick Kelly says the company already reports on plant emissions and now will provide more detail.
