Expanding the use of distributed storage in Texas could save money for customers by reducing the need for transmission and distribution infrastructure, according to a new report. The Texas Advanced Energy Business Alliance (TAEBA) concluded approximately $344 million would be saved each year for about 10 years if enough battery storage is installed to cut peak demand by 20 percent.
The calculation is based on the assumption that about 20 percent of all transmission and distribution investments in Texas are designed to deal with load growth. Additional batteries would allow such expenditures to be deferred, the authors argue, because the batteries could supply energy during peak demand.
“Customers would save substantially if non-wires solutions were explicitly considered as competitive options compared to traditional infrastructure build-out,” said TAEBA managing director Suzanne Bertin.
The TAEBA study did not specify which type of storage should be used. Instead, it stressed the importance of having distributed storage capacity capable of meeting demand during the afternoon in the summer and in the early mornings throughout the winter.
