Sustainability, Risk, and Reporting
24/7 carbon-free energy is an approach that attempts to match electricity consumption with carbon-free supply in the same hours and often in relevant grid regions. It is more stringent than annual REC matching and depends on granular data.
Available capacity is the portion of system capacity that may be usable after existing commitments, contingency criteria, maintenance margins, and operating limits are considered. It is more meaningful than raw nameplate capacity for site selection.
Read definition →Tier III is concurrently maintainable infrastructure: each capacity component and distribution path can be removed for planned work without affecting operations. It is a common target for enterprise and colocation facilities, but certification depends on detailed design and operations.
Read definition →Transmission is the high-voltage movement of bulk power across longer distances from generation or interchange points toward load centers. Transmission constraints are often the limiting factor for large-load data center growth.
