The Midcontinent Independent System Operator on March 25 filed with the Federal Energy Regulatory Commission a notice of termination of the Large Generator Interconnection Agreement with NextEra Energy Resources LLC (f/k/a FPL Energy Oliver Wind III LLC) and transmission owner ALLETE Inc. for a 48-MW project in North Dakota.
The LGIA was originally entered into between NextEra and Square Butte Electric Cooperative in 2009. Square Butte’s interest in the LGIA was subsequently assigned to ALLETE as part of an overall transaction concerning ALLETE’s purchase of certain high-voltage direct current (HVDC) transmission facilities and associated alternating current facilities from Square Butte. As part of that transaction, MISO and ALLETE submitted an Agency Agreement and proposed tariff revisions to effectuate the administration of transmission-related services over the HVDC facilities.
“Pursuant to Article 2.3.1 of the LGIA, the Parties mutually agree to terminate the LGIA, effective May 25, 2015,” said the notice to FERC. “Terminating this LGIA is appropriate as the Interconnection Customer, NextEra, no longer wishes to pursue this project (See Tab B, NextEra’s Notification of Termination Letter). The Transmission Owner, ALLETE, hereby agrees to cancel any pending orders of any materials or equipment for, or contracts for construction of, the Transmission Owner’s interconnection facilities, network upgrades, generator upgrades and upgrades on affected systems contemplated by the LGIA.” That letter from NextEra doesn’t give a reason for the termination.
Said the LGIA, filed with the commission in January 2010, about this project: “The Interconnection Customer’s Generating Facility project (GS661) shall consist of thirty-two 1.5 MW, GE xle, Wind Turbine Generators (WTGs). Each WTG shall connect to a 34.5 kV collector feeder through a 1750 KVA, 575 voltl34.5kV padmount transformer. Each collector feeder shall be terminated at the 34.5kV bus, at the low side of the main step-up transformer, within the project’s substation. The main step-up transformer shall be rated at 34.5/230kV and 36/48160 MVA. The project’s substation will be tied to the Transmission Provider’s 230kV Substation near Center, North Dakota (‘Square Butte Substation’).”
Under that agreement, the project was due for commercial operation in December 2010.
NextEra Energy Resources previously developed its Oliver Wind I (50.6 MW, went commercial in 2006) and Oliver Wind II (48.6 MW, commercial in 2007) projects at this North Dakota location.
