Opinions vary on how much U.S. electricity demand may rise and how much that may impact demand for natural gas. But there’s across-the-board agreement that the electric and gas sectors are more intertwined than ever and electric-grid reliability will suffer if gas-fired plants don’t get the fuel they need.
In the three years since the deadly electrical outages caused by Winter Storm Uri, the Texas Legislature, the Public Utility Commission of Texas (PUCT), and the Electric Reliability Council of Texas (ERCOT) have been working overtime to design and implement changes to ensure a more reliable Texas power grid. But it hasn’t been easy. The state’s energy-only electricity market and its outsized reliance on intermittently available wind and solar power have forced policymakers, regulators and the electric-grid operator to develop a wide range of fixes aimed at maintaining a competitive atmosphere while at the same time incentivizing market players to have power available when it’s needed most. In today’s RBN blog, we look at what they’ve been up to.
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.
The “polar vortex” of 2014 dipped far south enough to impact power markets in Texas. On Monday January 6th, the Electric Reliability Council of Texas (ERCOT) came dangerously close to initiating rolling blackouts as power demand increased due to record low temperatures and unexpected generation unit outages. Real time electricity prices spiked to over $5,000/ Megawatt Hour (MWH). The close call served as a sobering reminder for Texas regulators of the ongoing debate over how the State will meet future power generation requirements. Today we detail the “polar vortex” event and explain the implications for Texas power.
