Shared grid facilities deal filed for two wind farms in Michigan

Big Turtle Interconnection LLC (BTI) filed on Sept. 19 at the Federal Energy Regulatory Commission a shared facilities agreement among BTI and the developers of two wind projects in Huron County, Michigan; Big Turtle Wind Farm LLC (BTWF) and Terrapin Energy LLC.

BTI asked for a waiver of the commission’s notice requirement in order to permit an effective date of Sept. 20. Good cause exists to grant the requested waiver so that the agreement can become effective on the same date that Terrapin expects to begin producing energy for delivery to the transmission system.

BTI is a Michigan limited liability company with membership interests owned 40% by BTWF and 60% by Terrapin. BTI owns interconnection facilities and is party to a generator interconnection agreement (GIA) with International Transmission d/b/a ITCTransmission and the Midcontinent Independent System Operator. The GIA allows for the interconnection of 50 MW of wind facilities to the transmission system owned by ITC and operated by MISO.

BTWF owns and operates a wind project delivering up to 20 MW at the point of interconnection, and Terrapin owns and operates a wind farm that will be delivering up to 30 MW at the point of interconnection. BTI owns, leases, and/or operates interconnection substation facilities that are necessary for the interconnection of the BTWF and Terrapin wind projects to the transmission system, including a substation easement that BTI, BTWF, and Terrapin own and access as tenants in common.

Incidentally, FERC on Aug. 31 accepted a July 5 filing from Terrapin Energy LLC of its market-based rate tariff and granted the company the authority to sell electric energy, capacity, and ancillary services at market-based rates. It’s project, called the Big Turtle II Wind Farm, is a qualifying facility (QF) under the Public Utility Regulatory Policies Act of 1978, as amended.

Terrapin Energy is a wholly owned subsidiary of GFS US Holding LLC, which is a wholly owned subsidiary of GFS Holding Inc.
