While LUMA does not build, operate, or maintain EV Charging stations, we will continue to improve the electrical grid to support the expansion of charging networks.
These are some of the benefits that Electric Vehicle (EV’s) owners enjoy:
Save Money: EVs are more energy efficient and have a lower operating cost than traditional vehicles. Additionally, electric vehicles do not require changing oils, spark plugs, air filters and other parts that would need changing in gasoline engine vehicle, resulting in reduced maintenance costs.
No More Gas Stations: With electric vehicles there’s no gas to burn or gas to buy. Charge your car at home overnight or at work if your employer offers workplace charging.
Performance: Electric motors provide instant torque, resulting in quick acceleration and responsive performance.
Benefits to the Environment: EVs produce zero tailpipe emissions, reducing air pollution and greenhouse gas emissions that contribute to climate change.
Quiet and Smooth Operation: EVs are quieter and offer smoother acceleration compared to traditional vehicles contributing to reducing noise pollution in urban areas.
Incentives: Customers may also receive incentives for owning an EV. Currently, the Puerto Rico Department of Treasury grants a refund on some taxes paid on electric or hybrid vehicles. Learn more at: Departamento de Hacienda – Determinación Administrativa Núm. 11-08.

LUMA’s EV Time of Use (TOU) Residential Rate
As part of LUMA’s efforts to respond to the increasing number of Electric Vehicles circulating in Puerto Rico, LUMA launched the EV TOU Rate Pilot Program for residential customers with Eligible Vehicles and Chargers.
With the EV TOU Residential Rate, the cost of electricity needed to charge your EV varies based on the time of the day. Learn below how this rate works and the Benefits of the EV TOU Residential Rate.
How does the EV TOU Rate work?
The EV TOU Residential Rate empowers LUMA customers to choose how they manage their charging needs and allows them to save money by paying a less expensive rate depending on the time of day they decide to charge their EVs.
The graph shows how the cost of charging your EV varies throughout the day when you Enroll for LUMA EV TOU Residential Rate. Once enrolled, the customer will be charged based on all EV charging electricity consumption recorded through the customer’s Eligible Vehicles and Chargers.
Check the EV TOU Pilot Program’s Rules and Eligibility to learn more about pricing periods, tariff, and other applicable rules.

EV TOU Rate Pilot Program
The EV TOU Rate Pilot Program is designed to provide special rates for residential customers with Eligible Vehicles or Chargers. During the pilot period, a limited number of 500 eligible vehicles or chargers will have access to the rates. After the pilot period of 12 months is completed, LUMA will study expanding the number of customers to the program.
The EV TOU Rate Pilot Program is scheduled to be launched on April 30th, 2024. Check the Program’s Rules and Eligibility and see how you can Enroll for LUMA EV TOU Residential Rate.
Why a Pilot Program?
The pilot program is intended to be in effect for 12 months so LUMA can monitor and evaluate the EV charging consumption data and customer behavior to support the decisions related to extension, scaling, and future improvements for this and other programs on LUMA’s EV team’s outlook.
Rules and Eligibility
Who can participate in this program?
Eligible Vehicles or Chargers
Even if your vehicle is not eligible, having a ChargePoint® Home Flex charger or Wallbox Pulsar Plus charger makes you eligible for the program.
New manufacturers, models and years may be added in the future, please check the WeaveGrid website for the most updated list.
Technical Requirements
What do I do if have more than one EV?
It is possible to register more than 1 vehicle to the same account. However, the following conditions should be met:
Refer to WeaveGrid Frequently Asked Questions (FAQ).
Eligibility Terms and Conditions
For more information on the EV TOU pilot programs’ rules and eligibility, please refer to the Terms & Conditions.
Net metering customers
Customers who own or plan to own a solar photovoltaic system with or without a battery storage system will be allowed to enroll in the EV Time of Use Rate. However, since LUMA cannot at this moment discern whether the enrolled EV is being charged by the PREPA electrical system or the Participating Customer onsite generation source, LUMA will bill such Participating Customers based on the main assumption that all energy used for charging the enrolled EV is being always provided by the PREPA electrical system.
EV TOU Tariff
The EV TOU tariff, filed on April 29, 2024, can be found at Puerto Rico Energy Bureau Docket NEPR-MI-2021-0013.
*The Fuel Cost Adjustment (FCA) is updated quarterly. Please refer to the Puerto Rico Energy Bureau Docket: NEPR-MI-2020-0001 (Puerto Rico Electric Power Authority’s Permanent Rate) for the current approved FCA value*. Additionally, LUMA keeps records of all tariffs approved by PREB here:
*LUMA does not generate electricity and does not determine the final impact that fuel costs may have on customer rates.
How do I know how much I will pay each month?
For Q2 2024, the FCA, approved by the Puerto Rico Energy Bureau, was defined as $0.114585 per kilowatt hour (kWh). This value is valid during the period of April 1, 2024, to June 30, 2024.
The table below contains an example of the EV TOU tariff calculation.
* Additional tariff riders are applicable. See below what changes in your LUMA Bill
Notice that the FCA may change each quarter, and the Puerto Rico Energy Bureau will approve and publicize it. Again, LUMA does not generate electricity and does not determine the final impact that fuel costs may have on customer rates.
What changes in my LUMA Bill?
Not much!
In the Service and Meter Information section of your bill, you will see the EV TOU charges are added to the Current Charges Detail box.
You will see how much electricity you used in each pricing period in the month multiplied by the current approved EV TOU tariff. Notice that the EV TOU tariff is a blended rate, comprised of the FCA factored by the time you consume the electricity to charge your vehicle. While the customer and consumption charges tariffs in the Service Charges does not include the FCA, that goes in the Reconciliation Clauses.
You will continue to be charged all applicable riders to the General Residential Service (GRS) tariff.
For example, if you used 100 kWh to charge your vehicle in a given month, and your overall electricity consumption measured in your meter was 625 kWh, the FCA rider will be:
Billing cycle
The billing cycle is the monthly billing period that begins and ends on an invoice. Accounts for customers who enroll in the LUMA EV TOU Rate Pilot Program will begin having their meter read on the last days of each month. The billing cycle change may result in adjustments to the days and/or amount billed in the previous and/or current billing period. In the event that your invoice is adjusted, you will receive an invoice adjustment notification with the details.
If you have more questions about the EV TOU tariff and billing, please send an email to [email protected].

Fleet electrification is the process of replacing a group of traditional gasoline-powered or diesel-powered vehicles with electric vehicles (EVs) within an organization or business. This transition helps reduce greenhouse-gas emissions, mitigate climate change, and promote a cleaner, more sustainable transportation system. By adopting EVs, organizations can significantly cut costs, improve brand reputation, and contribute to environmental benefits such as reduced emissions and improved public health.
Fleet electrification offers several advantages, including operational and economic benefits, as well as positive environmental impacts. Let’s break it down:
In summary, transitioning to an electric fleet not only makes economic sense but also contributes to a greener future.
The U.S. Department of Energy in partnership with Argonne National Laboratory developed a tool to calculate the fuel savings based on where you are in the country. The Driving Electric: Local Fuel Savings Calculator (https://www.energy.gov/local-fuel-savings) compares the cost of driving a battery electric vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV) to a conventional vehicle where you live.
The example below shows the potential savings of replacing one (1) van in San Juan, PR (Zip code 00907).
To learn more about your potential fuel savings in your location, access https://www.energy.gov/local-fuel-savings.
The transportation sector represents the largest contributor to carbon dioxide emissions in our nation. Electric vehicles (EVs) present a promising pathway toward decarbonization. Factors such as declining purchase prices, advancements in charging infrastructure, cleaner electricity sources, and robust support from consumers and industry stakeholders contribute to the bright future of EVs. Recent commitments by governments and industry leaders underscore the growing momentum behind EV adoption worldwide.
Key developments include:
Staying ahead in this transition allows organizations to save costs and prepare for a sustainable future.
