Understanding Distribution Networks

Komponenty i operacje

Distribution networks form thee final link between high- voltage transmission systems andd end users. They consist of substations that step down voltage from transmissionon levels (typically 69 kV to 138 kV) to primary distribution voltages (4 kV to 35 kV), then further step down to secondary voltages (120 V to 480 V) via distribution transformers. These transformers servee clusters of homes, ois depariesses, or industrilal facilities.

Distribution transformas are sized based one thee estimate peek load of all connectod customers. With Evy, a new, highly variable load is commentee.

Increased Infrastructure Costs

Upgrading distribution infrastructure to handle EV loads is capital- intensive. The coss to replacee a typical 25 kVA residential distribution transformer with a 50 kVA unit can by $3,000- $5,000 per site. If 10% of transformers in a services territorior need upgrades, the total cos scales to millions of dollars for a medium- sized utility. Beyond transformators, feeders may need reconductoring, voltage regulators may need instaltion, and substation transformers may needs.
