Rapid-Start Power Plant Project
Update on the Rapid-Start Power Plant Project
February 19, 2025
The City of Sugar Land continually evaluates opportunities to stimulate economic growth. The Rapid-Start Power Plant Project presented a unique opportunity that aligned with these goals. After a thorough review of the proposed site, we have determined that the proposed site for a rapid-start power plant may be better suited for other developments that align with our long-term strategic planning goals. As a result, we have initiated the process to terminate the lease agreement, with the issue to be considered by Sugar Land City Council at a future meeting. We appreciate the expertise of those involved in the evaluation and remain committed to identifying trailblazing solutions that position Sugar Land for long-term success.
The City of Sugar Land is exploring the possibility of a rapid start power plant that will meet all the requirements and timelines set by the Public Utility Commission (PUC), Energy Reliability Council of Texas (ERCOT), the Federal Aviation Administration, and Texas Commission on Environmental Quality (TCEQ). This facility will provide at least 100 MW of dispatchable power generation. Its goal is to deliver clean and sustainable power to the Texas grid, enhancing grid resiliency in Texas and the surrounding region.
Additionally, the City is considering a revenue-sharing agreement with the developer. This agreement would allow the City to reinvest in infrastructure, maintenance, and economic development opportunities.
We have a strong interest in meeting with communities throughout the city starting in early 2025. As the feasibility studies will take most of the year to complete, we want to continue listening to concerns, answering questions, and better understanding public opinion related to this project as early as possible.
- Where will the plant be located?
-
The development will be located on an 8-acre parcel within the City’s planned 100-acre industrial park (Central Prison Unit Site). This city-owned property has direct access to Highway 6, Highway 90A, and future access to FM1464. The site is also located adjacent to the Sugar Land Regional Airport.
- How will the plant function?
-
The plant will use natural gas to provide resilient power to the Texas grid, balancing renewable energy and load within Sugar Land and the Greater Houston area. Highly efficient engines support ERCOT’s objectives of a stable and efficient power supply for energy and ancillary services. The plant will offer black start assistance during outages, aiding quicker recovery post-major events like hurricanes and winter storms. These units operate effectively even during severe weather, as seen in Winter Storm Uri, Winter Storm Elliot, and Hurricane Ida. Texas is rapidly transitioning to a renewable grid, with nearly 39,000 MW of wind and 22,000 MW of solar capacity. However, managing intermittent renewable generation poses challenges due to weather uncertainties, outages, transmission contingencies, and fluctuating customer usage. Traditional “Peakers” cannot resolve these challenges, but “Balancers” like Reciprocating Internal Combustion Engines (RICE) can. RICE technology features fast startup, immediate on-off cycling, low minimum operating levels, and fast ramp speeds of up to 60% total plant output per minute. With high efficiency and low emissions, this local power source can respond immediately to ERCOT’s increasing intermittency.
- When will the power plant be complete and online?
-
It is projected to be completed in late 2027-early 2028.
- Who will directly connect to the power plant?
-
The power plant will be connected to the ERCOT grid and become part of their operations.
- Who is financing the project?
-
This is a public-private partnership project, and project financing is still being negotiated at this time. Public tax dollars will not be used to fund the project.
- Does Fort Bend County fall within a nonattainment area?
-
Fort Bend County falls within one of the defined nonattainment areas within Texas. The map below shows the nonattainment counties in the state. These counties are held to a higher standard when it comes to air permitting. More can be found on the Texas Commission on Environmental Quality (TCEQ) website for air permitting.

- What is a nonattainment area?
-
Nonattainment Area
Defined as Areas that meet the NAAQS (National Ambient Air Quality Standard) are designated “attainment,” and areas that cannot be classified based on the available information, “unclassifiable.” For ozone, the federal Clean Air Act establishes nonattainment-area classifications ranked according to the severity of the area’s air-pollution problem.
- What are the required nonattainment compliance criteria for Fort Bend County?
-
The Houston-Galveston-Brazoria (HGB) area counties are included in the state's nonattainment classified areas which includes Fort Bend County. Visit the TCEQ website to review current HGB attainment status.
- What are nonattainment permits?
-
If a facility is located in a nonattainment area designated by the U.S. Environmental Protection Agency, additional permitting requirements may apply. In addition to the requirements identified as part of the New Source Review (NSR) permits, nonattainment permit review is required if the facility has emissions above the major source and significant thresholds for the specific county designated as nonattainment. Nonattainment permitting requires the installation of the lowest achievable emission rate control technology and the acquisition of emission reductions to offset the proposed emissions increases.
More information can be found on the TCEQ website.
The City is committed to meeting or exceeding the state and federal air standards established through the approved guidelines set by the EPA and TCEQ.
- What is the noise level from the plant itself? Will the noise be allowed during evening and nighttime hours?
-
Noise mitigation is included in the proposal. All noise impacts will be addressed with sound barriers and by housing equipment within buildings and in accordance with all state and federal laws. The plant will operate only when requested by ERCOT, rather than running 24/7. It will be active during periods of high demand, typically on hot summer days or cold winter days when energy usage peaks. Historically, these peak times occur between 4:30 and 8:00 PM, when people return home and energy consumption is at its highest.
- What is the purpose behind the city's Community Roadshows?
-
The mayor and staff were requested to attend community meetings to talk about the project, answer questions and listen to concerns.
- Are any more of these community meetings planned?
-
Yes, future events will be posted on the city website. City staff will continue to update the project page and be available to address any community concerns.
- What is the city doing to address concerns that may be based on misinformation or misunderstanding?
-
The city is committed to providing factual information and addressing all community concerns. City staff have responded to questions from the community since the media announcement for the project. We have also been working to make staff available to attend community meetings to talk about the project, answer questions, and listen to concerns.
The action City Council took on May 21 to approve a ground lease option agreement was done to grant access to conduct surveys, analysis, an interconnection study and an assessment that identified permits needed to ensure quality of life concerns such as air quality. Should the project proceed, a long term lease agreement will be considered by City Council.
- How will the power plant benefit the city?
-
We’ve known for a very long time that reliable power is important to our residents, especially during hot summer months and disasters like Winter Storm Yuri and Hurricane Beryl. The primary goal of this project is to deliver clean and sustainable power to the Texas grid, enhancing grid resiliency in Texas and the surrounding region. Adding capacity to the Texas grid and the surrounding region directly benefits our residents. A secondary benefit is the City is considering a revenue-sharing agreement with the developer. This agreement would allow the City to reinvest in infrastructure, maintenance, and economic development opportunities that help maintain one of the state’s lowest tax rates while also providing the high level of services our residents expect.
- What is the construction activity on 1 Circle Drive?
-
The activity is related to the construction of the Public Safety Training Facility and stockpile of materials for the upcoming Oyster Creek Diversion and Detention Facilities project that is currently under design to protect the Airport and Central Unit property from flooding during storm events.
- Will the community be able to vote for or against this project?
-
No election is currently planned. The city charter specifies a process for initiative. Learn more at https://www.sugarlandtx.gov/483/Sugar-Land-Charter.
- Because the lease is temporary, does that mean that the power plant could potentially not be constructed?
-
We are very early in the process. The city approved a ground lease option agreement on May 21 with Wärtsilä Development and Financials Services, Inc. to grant site access to facilitate surveys, soil boring, and analysis. A Full Interconnection Study (FIS) Application was submitted to ERCOT. Should the process continue, a future step would be a long-term ground lease and profit sharing agreement with a developer.
- Can you please provide an overview of how the plant will be operated and dispatched?
-
The plant will participate in the ERCOT market. This means that the plant will only operate when cost effective to do so. If power from ERCOT’s bulk power system is lower, like when wind and solar are producing at high levels, then the output of the plant would not be needed. However, as demand increases or when low-cost renewable generation is not available, the proposed power plant can provide reliable cost-effective energy. Importantly, this plant will be able to turn on and off quickly as system needs and prices dictate. This means it will not create unnecessary emissions or costs to customers because of operational limitations. Current estimates show the plant will initially run about 30%-35% of the time, minimizing both emissions and operating costs. It also offers black start capabilities, helping restore power during outages.
- Are there safety rules and regulations in place to ensure public safety?
-
The plant will adhere to strict U.S. and international gas safety regulations to ensure public safety. These include comprehensive standards for both construction and operation, governed by agencies such as the Occupational Safety and Health Administration (OSHA) and local regulatory bodies, ensuring the highest safety measures are in place.
- How will this power plant help reduce CO2 emissions and other pollutants?
-
This power plant will have two primary functions: helping balance the variability of renewable resources and addressing high demand. Balancing variability means that the engine power plant is able to ramp up for example if a cloud cover causes solar output to decrease and then ramp back down as soon as the clouds pass. The ability to operate a plant this flexibly allows the use of as much renewables as possible, as often as possible. Additionally, this power plant can help serve high demand and efficiently produce energy only when needed. This means lower CO2 emissions overall. Also, this plant will apply the best available emission control technologies to ensure compliance with local air quality requirements. As a final matter, the engines can be adapted to operate on a blend of carbon-neutral fuels. In future, the engines can be converted to use 100% carbon neutral fuels, enabling the 100% renewable power systems of tomorrow.
