What would be the nation’s largest wind farm has just landed a power purchase agreement with one of the nation’s top retailers. Walmart announced it will purchase energy from the 2 GW Wind Catcher project under development in the Oklahoma panhandle by PSO.

The total amount of energy Walmart will purchase was not disclosed, although Walmart officials said the project will help the company meet its goal of being supplied by 100 percent renewable energy.

The $4.5 billion project includes the development of a dedicated generation tie line to the Tulsa area. PSO said that, when Wind Catcher comes online in late 2020, it will be the lowest-cost energy on PSO’s system, and will allow the utility to deliver 40 percent of its Oklahoma electricity from wind.

Wind Catcher had been temporarily blocked by Oklahoma Attorney General Mike Hunter, though that block was quickly overturned by a Corporation Commission Administrative Law Judge.
