Your New Bill Design: FAQ

Your electric bill includes the charges evaluated and approved by the Puerto Rico Energy Bureau (PREB), the only entity responsible for setting electricity rates in Puerto Rico. 

Although LUMA sends bills to customers, your monthly payment is deposited into the Puerto Rico Electric Power Authority (PREPA) accounts, which then distributes the funds to the operators (LUMA and Genera PR) according to the contract terms. 

Here’s what each line of your bill represents: 

Service Charges: 

• Customer Charge (assigned to LUMA): Covers costs related to customer service, meter reading, and billing. 
• Consumption Charge (assigned to Genera PR, PREPA, and LUMA): Covers operational and maintenance costs. This charge varies depending on your rate and the amount of energy you use. 
• Additional Consumption Charge (distributed among Genera PR, PREPA, and LUMA): Applies if your energy use exceeds the established base consumption (425 kWh). 

Reconciliation Clauses: 

• Rider FCA – Fuel Cost Adjustment (for Genera PR): Covers the cost of the fuel used to generate electricity. 
• Rider PPCA– Purchased Power Cost Adjustment (for Independent Power Producers): Covers the cost of energy purchased from private producers using renewable and fossil sources. 
• Rider CILTA–CELI – Municipalities Adjustment: Covers the cost of eligible municipal accounts established by law. 
• Rider SUBA– Subsidies, Public Light and other Subv HH (legally mandated subsidies): Covers municipal public lighting, residential customer subsidies, and PREPA’s contributions to the PREB. 
• Rider SUBA – Subsidies, Public Light and other Subv HH NHH (legally mandated subsidies): Covers subsidies for non-residential customers and PREPA’s irrigation system accounts. 
• Rider EE – Energy Efficiency Charge (PREB program): Funds the implementation and management of energy efficiency programs. 
• Rider PENSION PAYMENTS – Adjustment pension costs (for PREPA): Covers pension payments for PREPA retirees. 
• Rider PROVISIONAL – Provisional Adjustment (distributed among PREPA, Genera PR, and LUMA): A PREB-approved charge effective from September 1, 2025, to June 30, 2026, covering operations and maintenance expenses. This is part of the rate review process aimed at securing funds to improve Puerto Rico’s electric system. The last rate review in Puerto Rico took place in 2017, and the previous review was in 1989, meaning that rates had not been updated for decades to reflect the system’s actual needs.
