 two interim rate adjustment applications per year to recover distribution-related investments placed into service between base rate review proceedings. PUCT rules also allow the Texas utilities to file up to two interim rate adjustment applications per year to reflect changes in transmission-related invested capital. These applications for interim rate adjustments between base rate reviews, known as “capital tracker” provisions, are intended to encourage transmission and distribution investments in the electric system to help ensure reliability and efficiency by helping to shorten the time period between a utility’s investment in transmission and distribution infrastructure and its ability to start recovering and earning a return on such investments. However, all investments included in a capital tracker are ultimately subject to prudence review by the PUCT in the next base rate review, after such assets are put into service.

Capital Structure and Return on Equity 

In April 2023, the PUCT issued a final order in Oncor’s comprehensive base rate review that set Oncor’s authorized ROE at 9.7%, a decrease from its previously authorized ROE of 9.8%, and maintained Oncor’s authorized regulatory capital structure at 57.5% debt to 42.5% equity.

Sharyland Utilities’ PUCT-authorized ROE is 9.38% and its authorized regulatory capital structure is 60% debt to 40% equity. 

Sempra Infrastructure

Ecogas’ revenues are derived from service and distribution fees charged to its customers in Mexican pesos. The price Ecogas pays to purchase natural gas, which is based on international price indices, is passed through directly to its customers. The service and distribution fees charged by Ecogas are regulated by the CRE, which performs a review of rates every five years and monitors prices charged to end-users. Ecogas’ rate case for 2021 through 2025 was approved by the CRE in December 2023. The tariffs operate under a return-on-asset-base model. In the annual tariff adjustment, rates are adjusted to account for inflation or fluctuations in exchange rates, and inflation indexing includes separate U.S. and Mexican cost components so that U.S. costs can be included in the final distribution rates.
