Commercial Fleet Electrification Underwriting Insights:

Commercial fleets transitioning to medium and heavy-duty EVs face severe utility demand penalties if unmanaged. Charging diversity software algorithms dynamically throttle individual charger output based on dwell time, reducing grid interconnection requirements by 20% to 35% and saving thousands in monthly recurring utility demand ratchet fees.
