A Residential City That’s Adding Load

Walnut’s General Plan describes the city’s goal as staying a suburban residential community with a rural character, and it shows: homes, parks and hillside trails make up most of the city. Many Walnut homes are now adding EV chargers, heat pumps, pools and larger kitchens, and the original panel often can’t keep up. We start with a load check and give you a clear plan before any work begins.
