Exelon: EV Hosting Capacity (Mainline & 3 Phase Lateral)

Note: Find data at source. ・ Pepco supports decarbonization and electrification impacts by providing timely and cost effective connections to the distribution grid for new customer loads and distributed generation.

Pepco anticipates rapid adoption of new electric loads that support decarbonization such as electric vehicle charging infrastructure and converting to electric heat sources. In order to help guide large scale electrification Pepco has developed a load capacity map to represent areas on the distribution grid where there is reasonable capacity to accommodate electric vehicle charging infrastructure and other load sources with lower probability of necessitating extensive equipment upgrades or line extensions that would add cost or time to projects. The map provides different levels of available load capacity on a circuit by color (Green greater than 1 MW, Yellow 0.5 MW to 1 MW, and Red less than 0.5 MW). The map also provides areas that only have single or two phase service available in magenta and would likely require system upgrades for load demands greater than 100kW. For project requiring greater than 4 MW of load demand a new express feeder would be required to service the load. The map linked below shows general areas where load capacity may be coming constrained and could require system upgrade scope to accommodate new load project connections.
