Power Fundamentals
Voltage is electrical potential difference and is one of the key variables in power delivery. For large-load sites, voltage class strongly affects interconnection options, equipment cost, substation design, losses, and whether service is closer to distribution or transmission.
Wastewater discharge is the release of used water from cooling, treatment, sanitary, or process systems under permit or utility rules. Data centers using evaporative or water-cooled systems must understand discharge volume, chemistry, temperature, and treatment requirements.
