Data Center Design and Operations
N is the base amount of capacity or equipment needed to support the design load. Redundancy expressions like N+1 and 2N only make sense after defining the load, component boundary, operating mode, and failure scenario.
A substation is a facility that switches, protects, transforms, meters, and controls power flows between grid elements or to a customer. For data center development, substation feasibility includes land, equipment, utility ownership, interconnection, transformer capacity, relay design, and schedule.
Read definition →EPA's eGRID is a database of electric generation and emissions attributes by grid region and plant. It is useful for estimating location-based emissions, but users should understand reporting year, regional boundary, and market-based procurement differences.
