Benton County Wind Farm LLC v. Duke Energy Indiana, Inc., No. 15-2632 (7th Cir. 2016)Annotate this Case
In 2005, Duke Energy bought, from Benton, renewable energy at a price high enough to enable construction of wind turbines, and acquired tradeable renewable‑energy credits. The contract requires Duke to pay Benton for all power delivered during the next 20 years. When Benton's 100-megawat facility started operating in 2008 it was the only area wind farm. Duke paid for everything Benton could produce. The regional transmission organization, Midcontinent Independent System Operator (MISO), which implements a bidding system for the network, cleared the power to the regional grid. By 2015, aggregate capacity of local wind farms reached 1,745 megawatts, exceeding the local grid’s capacity. At times, would‑be producers must pay MISO to take power; buyers get free electricity. Initially, MISO allowed wind farms to deliver to the grid no matter what other producers (coal, nuclear, solar, hydro) were doing, which meant that such producers had to cut back. On March 1, 2013, the rules changed to put wind farms on a par with other producers. Under MISO’s new system, with Duke’s responsive bid, Benton has gone from delivering power 100% of the time the wind allowed to delivering only 59% of the time. The district court agreed with Duke that, when MISO tells Benton to stop delivering power, it does not owe Benton anything, rejecting Benton’s claim that Duke could put Benton’s power on the grid by bidding to displace other power, and that when Duke does not, it owes liquidated damages. The judge found that bidding $0 is “reasonable” cooperation. The Seventh Circuit reversed; the contract implies that Duke must do what is needed to make transmission capacity available.
