LCG, April 29, 2025--Officials from the U.S. Environmental Protection Agency (EPA) and Texas Railroad Commission (RRC) signed a memorandum of agreement (MOA) today outlining the state’s plans to administer programs related to carbon storage wells, known as Class VI wells. The MOA signing is a required step in the RRC’s application to be granted authority to permit Class VI wells in the state of Texas. EPA is currently preparing a proposed approval of RRC’s primacy application.

LCG, April 24, 2025--Exxon Mobil Corporation (ExxonMobil) announced yesterday an agreement with Calpine Corporation (Calpine) to transport and permanently store up to 2 million metric tons per annum (MTA) of CO2 from Calpine’s Baytown Energy Center, a natural gas-fired facility located near Houston, Texas. This is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project that is designed to add CCS for the facility’s CO2 emissions. The Calpine facility could then provide a 24/7 supply of low-carbon electricity to the Texas grid plus steam to nearby industrial facilities.

ERCOT reviewed Frio County Transmission Project
June 18, 2020 - In November 2019, 7X Energy submitted the Frio County Transmission Project to the ERCOT Regional Planning Group (RPG) as an economic-driven project to address projected transmission congestion in the Frio County area. This is supported by an independent economic benefit study performed by LCG Consulting using its proprietary UPLAN model, the same economic planning model utilized by ERCOT, in accordance with ERCOT procedures. LCG’s analysis shows significant annual production cost benefit for the transmission upgrades in question.
In the independent review completed in May 2020, ERCOT identified transmission congestion on the 69-kV and 138-kV transmission system in Frio County, and a total of seven transmission upgrade options were evaluated. ERCOT concluded that the upgrades identified in Option 5 would provide the most cost-effective solution to the identified congestion while meeting the ERCOT economic planning criteria. Option 5 is estimated to cost $12.13 million and is described as follows:
- Rebuild the Moore – Big Foot 138-kV line such that the summer normal and emergency ratings are at least 485 MVA
- Reconductor the Moore – Hondo Creek 138-kV line such that the summer normal and emergency ratings are at least 382 MVA
The recommended option is classified as a Tier 2 project based on the ERCOT Protocol Section 3.11.4.3(2), and the project is expected to be in-service by Summer 2021.
