Energy Transfer Planning Small Gas-Fired Facilities to Maintain Power Supply at TX Operations

Everyone in Texas remembers the infamous Winter Storm Uri of three years ago. What started out as a simple cold snap for many quickly turned into something far more serious: the biggest power outage in state history, with billions of dollars in property damage and hundreds of lives lost. Since then, the expected arrival of frigid temperatures has been met with some trepidation, but the critical failures of February 2021 have so far been avoided in subsequent storms. In today’s RBN blog, we look at the steps the state has taken in recent years to weatherize its power grid, show why January’s cold snap turned out to be no big deal, and explain why renewables are playing an increasingly important role in grid reliability during extreme weather conditions. 

Power generation is one of the leading consumers of natural gas in Texas — every month last year, generators in the state used between 4 Bcf/d and 8 Bcf/d, on average, with the volumes peaking (as you would expect) in August, when air conditioning and a friend with a pool are must-haves. But as we’ve seen, the Texas power grid is often stressed to its limit, and the state has been taking steps to significantly increase the gas-fired generating capacity available for peak-demand periods in both the hottest and coldest months. In today’s RBN blog, we discuss one of the state’s boldest steps yet: the creation of a multibillion-dollar fund to support the development of thousands of megawatts of new gas-fired generation. 

In Texas, rising power demand, increasing dependence on variable-output renewables, and declining availability of dispatchable fossil-fired plants to back up wind and solar have left the Electric Reliability Council of Texas (ERCOT) power grid in a pickle. As part of its response, the Public Utility Commission of Texas (PUCT) adopted a tool called the Performance Credit Mechanism (PCM) to help ensure the grid will be able to meet a yet-to-be-defined reliability standard. But while key metrics for the PCM have been identified, the details will determine which dispatchable resources will be supported with additional revenue, how much the whole approach will cost, and how effective it might be. In today’s RBN blog, we explore the debate ahead of the PUCT’s August 29 meeting — where it is expected to finalize rules around the PCM — and explore the difficulty of compensating generators annually so that they are also there for those once-in-10-year events.
