# Battery-backed EV charging cut grid draw during PJM peak events

> Electric Era says its charging controls predicted all five 2026 PJM coincident peaks and used onsite batteries to lower one station’s grid draw during those hours.

## Peak-hour performance

The system identified the five summer peak events with 97% confidence. At one site, chargers delivered an average 72 kW to vehicles while drawing 9 kW from the grid, reducing peak load contribution by 63 kW.

## How the system works

The software prepares an onsite battery for likely peak periods and manages power shared between the grid, storage and vehicle chargers. The publication estimates about \$12,000 in annualized capacity-charge savings at the reported site.
