Maine's South Portland City Council has passed an electric vehicle charging infrastructure ordinance that will require new/reconstructed parking lots to add EV charging infrastructure at the opportune time to prevent expensive retrofits at a later date.

The new rule is set to go into effect on December 5, 2022.

For employee parking, at least 40% of spaces must be "EV-capable" or have the electrical panel capacity and space to support each EV parking space.

New or reconstructed parking structures or lots of 5-plus parking spaces will be required to add EV-capable infrastructure while lots of 25-plus spaces will need to add EV-installed infrastructure.

Exemptions/reductions include:

  • Affordable housing projects (120% AMI in 33% of dwelling units) can reduce requirement to 0.5 spaces per unit

  • Can substitute with Level 3 at a ratio of 2:1

  • Projects of 10+ EV-installed spaces may further reduce panel requirement to 1.4 kW per space

  • Planning Board can waive/delay requirements due to supply chain disruptions

  • ADUs are exempt

  • Motorcycle/moped spaces per exempt
