Data center giant Digital Realty has signed a long-term power purchase agreement to use solar power for a portion of its Northern Virginia portfolio, and a utility green tariff to supply renewable power to its Oregon campus.

Together, the deals will add 227,000 megawatt-hours (MWh) of renewable energy to the grid, the company claimed.

The Northern Virginia deal will see Engie North America supply 107,000 MWh of additional renewable solar power annually, once its 50MW solar farm comes online in late 2020.

In Oregon, Portland General Electric will supply approximately 120,000 MWh every year to Digital Realty's Hillsboro data centers, under the utility's Green Future Impact program. PGE will source new solar or wind generation in the state on behalf of the real estate invest ment trust company.

“We place a high priority on sourcing net-new renewable energy as we expand our portfolio, and each market has its own unique pathway to identifying and realizing impactful and cost-effective renewable solutions,” Digital Realty senior director of sustainability, Aaron Binkley, said.

The company says it has procured renewable energy for all of its EMEA data centers, has enough wind power to offset its entire US colocation business, and supplies 100 percent renewable power to "several" Northern California properties.
