The Midcontinent Independent System Operator on July 5 filed with the Federal Energy Regulatory Commission an Amended and Restated Generator Interconnection Agreement with MidAmerican Energy as both the power project developer and interconnecting transmission owner.
This agreement is being amended a third time to change the manner in which the generating facility will provide reactive support. It is being filed with the commission because this change represents an amendment to the Second Revised LGIA, which was previously filed with and accepted by the commission.
