Renewable Energy Credit Program

The new Renewable Energy Credit Program is Council-approved. The program begins May 1, 2021, and allows customers to purchase energy that has been metered and verified from renewable sources, including wind and solar power. 

A Renewable Energy Credit (REC) represents one-megawatt hour (MWh) of renewable energy. Purchasing a number of RECs that equal the number of MWh of energy used allows customers to power residences or businesses with 100% renewable energy. 

Renewable energy capacity has increased statewide since the Public Utility Commission of Texas established the Renewable Energy Credit Program in 1999. By 2010, Texas’ renewable energy capacity increased by 10,000 MW statewide, attributable to the program.   

Renewable Energy Credit Costs 

RECs are a certifiable way to buy and sell renewable energy. Each REC is assigned a unique serial number, which guarantees that transactions can be tracked and recorded. 

San Marcos Electric Utility (SMEU) purchases RECs through the Electric Reliability Council of Texas at market price. Fees are evaluated and adjusted periodically based on the market, and customers are only charged for the amount of energy used.   

Customers that choose to enroll in the Renewable Energy Credit Program will see a “Renewable Energy Adder” charge on their monthly bill. The additional $5/1,000 kWh charge covers all costs associated with RECs, including transaction and administrative fees for buying, tracking, recording, and retiring the credits. Customers that do not elect to enroll in the Renewable Energy Credit Program will not be charged for costs associated with the program.  

Enrolling in the Renewable Energy Credit Program 

SMEU customers are invited to enroll in the Renewable Energy Credit Program beginning May 1 on the Customer Connect website connect.sanmarcostx.gov. Customers will opt-in for a period lasting one year. Prior to the end of their enrollment period, customers will be contacted with rates for the upcoming year and will be automatically re-enrolled unless they contact SMEU to opt out of the program.  

Following enrollment, new customers will see the “Renewable Energy Adder” charge at the beginning of their next billing cycle. Market prices for RECs may vary over time, however, customers will only be charged the price stated during sign-up or renewal despite market fluctuations.
