What is a Private Electrical Network?
A private electrical network is an electrical distribution system owned and managed independently from the local Distribution Network Operator (DNO). This gives you greater control over your power supply, network performance, and energy efficiency.
Common in industrial estates, airports, university campuses, and large commercial properties, private networks are essential for resilience, flexibility, and cost control.
