Facebook and Pacific Power plan 437 MW of solar in Utah, Oregon


Much of the early development of large-scale solar in the Western United States was in California, with Arizona, Nevada, Colorado and New Mexico playing significant if lesser roles. It wasn’t until three years ago that Utah’s first large-scale solar projects went online, and despite ample sun east of the Cascade Mountains the vast majority of solar in Oregon to date has come online in the last two years.

Now these markets are catching up, through a combination of drivers including must-take contracts under the Public Utilities Regulatory Power Act of 1978 (PURPA), Oregon’s aggressive renewable energy mandate, and at times corporations – including tech giants who chosen sunny rural areas for massive data centers.

As the latest, Pacific Power has announced that it is partnering with Facebook for the construction of 437 MW of solar projects in Oregon and Utah. No additional information was provided in a Pacific Power press release on the four projects in Utah, which are likely to serve Facebook’s new Eagle Mountain Data Center, however there is some limited information regarding the two Oregon projects, which were the subject of a public announcement featuring Oregon Governor Kate Brown (D).

And here, the role of Pacific Power becomes more clear. In the case of Oregon, the utility’s position is to act as a middle man between Facebook and developer Invenergy, which is building two projects totaling 100 MW to serve the social media giant’s latest data center in Prineville, northeast of Bend in sunny Eastern Oregon.

Invenergy declined to provide any additional information to pv magazine on these projects, even their location, but the name of one of the plants – Millican – gives a clue. Millican is a semi-abandoned town (population:4?) on a desolate stretch of Highway 20, a road that the author once drove for about 100 miles without finding a gas station. Sunlight is the one thing that the town has ample amounts of, besides sagebrush, juniper and pine trees, and on Highway 20 wild horses outnumber human residents.

However, Pacific Power states that both projects are in Crook County, Oregon, and Millican is just over the border in Deschutes County, so it is probable that the 45 MW project is north of Millican. Either way, the estimated 100 workers that the plant will require to build will likely have to commute from Bend, Prineville or Redmond, as some of the few towns less than 40 miles away that have services or more than a few hundred residents.

Invenergy has stated that it expects to have the 55 MW Prineville and 45 MW Millican plants online in late 2020. When complete, Facebook expects this data center to be 100% powered by renewable energy.

These data centers have brought welcome economic development and tax revenues to Prineville, which had an estimated 17% unemployment when Facebook built its first data center there.

These may not be the only projects build in the area, as Portland General Electric is seeking an amount of renewable energy that would translate to 500-620 MW of utility-scale solar on trackers, and any solar plants would be far less productive in the rainy Williamette Valley to the south of the city.

And who knows? Millican might even get some new human residents.
