Walmart Inc. entered into three power purchase agreements with Houston-based EDP Renewables North America that will enable the construction of three utility-scale wind farms in Illinois and Indiana.

EDP Renewables will develop, own and operate the wind farms, according to an Oct. 16 news release.

The agreements take the Arkansas-headquartered retail chain a step closer to its goal of sourcing 100% of its energy needs from renewables, said Walmart Vice President for Energy Mark Vanderhelm.

Walmart will source 123 MW from the 205-MW Lexington Chenoa Wind Farm (Bright Stalk) Wind Farm in McLean County, Ill.; 60 MW from the 200-MW Headwaters II Wind Farm in Randolph County, Ind.; and 50 MW from the 200-MW Harvest Ridge Wind Farm (Broadlands Wind) in Douglas County, Ill.

The three wind farms are expected to go online between 2019 and 2020. EDP had previously announced it had secured the power purchase agreements but did not name the counterparty.

EDP Renewables is the North American renewable energy unit of Portugal-headquartered EDP - Energias de Portugal SA.
