LUMA ordered to file draft rate designs for EV system by Tuesday

It is estimated that switching from gasoline vehicles to comparable electric vehicles in Puerto Rico would result in a reduction in CO2 emissions per mile of between 20% and 33%.

As the Federal Emergency Management (FEMA) gave the green lights to streetlighting distribution projects in three municipalities, the Puerto Rico Energy Bureau (PREB) has ordered LUMA Energy to file by Tuesday the draft for rate designs for an Electric Vehicle (EV) Charging Infrastructure Deployment Plan.

On June 15, there will be a technical hearing and on June 30, LUMA must file a final proposal for one or more rate designs. On Sept. 1, LUMA must file a draft for an EV plan, which will be followed by a hearing on Sept. 15.

The final EV plan must be filed by Sept. 30.

The environmental organization CAMBIO PR has said the deployment of electric vehicles would significantly increase electricity demand in Puerto Rico and requires forethought and planning for the necessary infrastructure upgrades.

Switching from a gasoline vehicle to a comparable electric vehicle today in Puerto Rico would result in a reduction in CO2 emissions per mile of between 20% and 33%, depending on which of the Puerto Rico Electric Power Authority’s units are the marginal generators, the group said.

“However, Puerto Rico should avoid the situation where EV deployment increases demand for fossil fuel-based generation,” CAMBIO PR said. “It is thus essential that deployment of electric vehicles go hand in hand with the accelerated deployment of renewable energy on the grid. Under scenarios of much higher renewable energy deployment, in which electric vehicle charging can avoid curtailment of solar generation, the emissions reduction benefit of electric vehicles will be much higher.”

“Aggressive deployment of electric vehicles in Puerto Rico, in line with the targets set by the states of New York and California of eliminating sales of gasoline-powered vehicles by 2035, would result in a significant increase in electricity consumption,” the group said. “We estimate that if electric vehicle sales ramp up to 100% of new vehicle sales by 2035, this would result in an increase in annual electricity.”
