Apple is expanding its energy resources in the data center of North Carolina.

The Charlotte Observer reports that Apple is planning to double the size of its energy resources at its data center in Maiden, North Carolina to 10 megawatts.

"Fifty fuel cells adjacent to its $1 billion data center in Maiden are expected to be operating by January, Apple said in papers filed with the N.C. Utilities Commission. It will be fueled by “directed biogas” in which cleaned methane gas from a landfill is injected into a natural gas pipeline. [...]

California-based Apple says the initial 4.8-megawatt phase in Maiden began start-up and testing in October. In November it applied for an amended state permit to increase the project’s size."

North Carolina Apple data center consolidates its fuel resources with two massive solar farms to assist the company achieving the goal of using 100% renewable energy sources in all of its data centers. The originally planned fuel resource object of Apple in North Carolina with 4.8-megawatt capacity, is the largest in the United States, and is not owned by any utility company.
