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.

Hawaiian Electric Begins Implementation of New Solar Option for Homeowners
LCG, August 5, 2016--Hawaiian Electric Company announced Tuesday that a new kind of rooftop solar system that enables households to generate their own electricity and to potentially store energy for when the sun is not shining is now being approved and installed on island homes. The island's first approved "self-supply" rooftop system was recently turned on at a home in Honolulu.
The new, self-supply systems, believed to be the first in the U.S., are now being installed under Hawaiian Electric Companies' Customer Self-Supply Program, an alternative to the popular Customer Grid-Supply Program.
The self-supply systems are designed specifically for the Hawaiian market and use new inverter technology to provide power to the home but prevent any excess electricity from being injected back into the distribution grid. By not allowing injection back into the grid, the utility can avoid pushing physical limits of the distribution system and causing related problems. This concern is more significant in Hawaii, where rooftop solar PV has been rapidly installed. Given Hawaii's Renewable Portfolio Standard (RPS) goal for each utility to achieve 100 percent renewable energy by 2045, solar power generation is likely to continue to increase in Hawaii.
Hawaiian Electric's Senior Vice President of Customer Service stated, "It's been five years since rooftop solar really took off in Hawaii and more than 77,000 customers have made the choice to use it. The shift to self-supply is an important evolutionary step to ensure that the rooftop solar option remains sustainable, cost-effective and available to some of the 85 percent of customers who don't have it."
There is a growing number of self-supply systems available from a number of vendors that now meet the specifications set by the Hawaii Public Utilities Commission (PUC). Hawaiian Electric has been working with these companies to develop standard technical specifications that will qualify systems for an expedited approval and potentially faster installation.
The PUC created the Customer Self-Supply Program as an alternative to the grid-supply program, especially once the grid-supply capacity limits established by the commission were met.
The Customer Grid-Supply program, which credits customers for the excess electricity they send to the grid, remains available on Oahu, though space is going fast. Maui Electric recently reached the capacity limit set by the PUC and Hawaii Island is nearing the limit, but self-supply is available.
