CenterPoint Energy Deploys Mobile Generators to San Antonio, Reducing Houston Customer Bills
Table of Contents
To bolster energy grid reliability this summer, CenterPoint Energy has initiated the deployment of 15 large mobile generators to the San Antonio area. The Texas utility announced Monday that this strategic move aims to mitigate potential energy shortfalls and provide significant cost benefits to customers.
Mobile Generator Deployment Details
The installation of the first five mobile generator units is underway, with the remaining ten slated for installation in the coming weeks. These generators, ranging from 27 MW to 32 MW, were acquired following the severe disruptions caused by Winter Storm Uri in 2021, which exposed vulnerabilities in the texas power grid.
Did You Know? the Electric Reliability Council of Texas (ERCOT) determined that the retirement of CPS energy’s V.H. Braunig Units 1, 2, and 3 posed a significant risk to the system, prompting the need for these mobile generators.
impact on Customer Bills
Jason Ryan, CenterPoint’s executive vice president of regulatory services and government affairs, stated that this deployment would “instantly lower monthly bills for our Houston-area customers.” The utility projects that Houston-area customers will see a reduction of approximately $2 per month by 2027 because of this initiative.
CenterPoint Energy will not receive any revenue or profit from the 15 large units based on the agreement with ERCOT.This decision comes after criticism when the mobile units were not deployed after hurricane Beryl last summer, leading the utility to forego profits associated with the mobile generation lease.
ERCOT Agreement and Grid Value
According to the ERCOT agreement, the retirement of CPS Energy’s V.H. braunig Units 1, 2, and 3 “poses a significant risk” to the system.These units help mitigate the risk of cascading outages associated with the post-contingency overload of certain transmission lines importing power into the greater San Antonio area.
ERCOT recommended that Unit 3 continue operating under a reliability must-run agreement but determined that CenterPoint’s mobile fleet “could help further mitigate the identified reliability risks more cost-effectively than committing V.H. braunig Units 1 and 2 through RMR agreements.” CenterPoint estimates that its generators will deliver approximately $200 million of value to the state’s grid. The agreement with ERCOT indicates the generators could run until March 2027.
Pro Tip: Grid resilience is crucial for preventing widespread outages and ensuring a stable energy supply during extreme weather events.
CenterPoint’s Resilience Initiatives
In response to past events like Hurricane Beryl, CenterPoint has been proactive in enhancing grid resilience. The utility proposed a $5 billion investment into Houston-area grid improvements. In May, CenterPoint announced the completion of critical portions of its Greater Houston Resiliency Initiative, which included installing 26,000 storm-resilient poles, moving 400 miles of power lines underground, and adding over 5,100 automation devices to the electric system U.S. Department of Energy.
| Metric | Value |
|---|---|
| Number of Generators | 15 |
| Generator Capacity | 27 MW – 32 MW per unit |
| Projected Bill Reduction for Houston Customers | $2/month by 2027 |
| Estimated Value to State Grid | $200 million |
| Potential Operational End Date | March 2027 |
future grid Planning
CenterPoint Energy is also focused on long-term grid improvements to combat extreme weather threats and future hazards. The company submitted its enhanced Systemwide Resiliency Plan (SRP) to reduce storm-related outages for its 2.8 million customers Texas Reliability Coalition.
Evergreen Insights: Understanding Grid Resilience
Grid resilience refers to the ability of an electrical grid to withstand and recover quickly from disruptions, such as natural disasters, cyberattacks, or equipment failures.A resilient grid ensures a reliable power supply, minimizing economic and social impacts during emergencies. Investments in grid modernization, including advanced technologies and infrastructure upgrades, are crucial for enhancing resilience.
the texas power grid has faced significant challenges in recent years, including the devastating Winter Storm Uri in 2021. These events have highlighted the need for proactive measures to strengthen the grid and protect communities from future disruptions. Strategies such as diversifying energy sources, improving infrastructure, and implementing robust emergency response plans are essential for building a more resilient energy system.
