EGP-NA’s strategic relationship with Tradewind, struck more than a decade ago, has helped the Italian company transform into one of the largest owners of utility-scale renewables in the U.S. The two companies together have been at the vanguard of the trend of major corporations signing up to buy large volumes of renewable power.

EGP-NA is looking to add around 1 gigawatt of renewables capacity each year in the U.S. during the 2019-21 period, most of it likely to be wind.

Earlier this month EGP-NA finalized the acquisition of seven renewables plants totaling 650 megawatts from GE Energy Financial Services, including the 400-megawatt Cimarron Bend wind farm in Kansas.

The acquisition of Tradewind suggests that more of EGP-NA’s future capacity will come from in-house development, rather than buying advanced projects from other developers, as it has recently done in states like Texas.

The acquisition will allow EGP-NA to move with “greater speed and efficiency” in the “competitive U.S. market,” said Georgios Papadimitriou, who took the helm at the company last year.

In addition to its EGP-NA unit, Enel is also active in the U.S. through the recently launched Enel X, its e-solutions division that has roped together various acquisitions, including Demand Energy, EnerNOC and eMotorWerks.
