reliability

The U.S. power sector is undergoing a major expansion to keep pace with the rising demand for electricity from data centers and other consumers, and trying to do a lot at once. Keep a lid on greenhouse gas (GHG) emissions by adding wind, solar and other renewables. Maintain grid reliability by supplementing variable renewable energy with more around-the-clock sources like natural gas-fired power plants. Oh, and keep power costs down, too. That’s a big collective ask, and to help make it possible, power grids are turning to so-called “virtual power plants” (aka VPPs) that, with an assist from computers and software, aggregate smaller power sources, batteries and flexible demand to provide power to the grid much like a traditional combined-cycle plant would. In today’s RBN blog, we’ll introduce VPPs and explain why they’re worth learning about. 

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. 

As nobody in Texas will soon forget, in February of this year freezing temperatures across the southern U.S. hammered energy markets and resulted in widespread and long-lasting blackouts across the Energy Reliability Council of Texas (ERCOT) power region. Life for many Texans came to a standstill for a week until power could be restored. The resulting economic damages have been estimated in the billions. Many people, rightfully, questioned how an energy-rich state like Texas could have been so affected. And then the blame-game started. Lacking a forum of qualified experts, productive discussions took a back seat to self-serving rhetoric, special-interest advocacy, and political posturing. But if real solutions were going to be found, it would take more than finger-pointing. It would take a meeting of experts whose primary focus was a resolution, rather than a constituency. Fortunately for Texans, that’s what they got two weeks ago. In today’s blog, we take you through the symposium and its outcome, particularly regarding the role of natural gas.
