- Last Energy plans to build 30 microreactors in Haskell County, Texas, to meet rising data center energy demands, with power supplied via private wires and grid transmission. The company has submitted a grid connection request and is preparing for regulatory approvals.
- The company is expanding globally, with projects in Europe and the UK, while also exploring developments in Utah. Its modular pressurized water reactors (20 MWe) will be built off-site for efficient deployment, supporting the clean energy transition.
US-based microreactor developer Last Energy has unveiled plans to construct 30 microreactors in Haskell County, northwest Texas, to meet the increasing energy demands of data centers across the state. The company will develop the reactors on a 200-acre site and will provide power to off-takers through a combination of private wires and grid transmission.
As part of the initiative, Last Energy has already submitted a grid connection request with the Electric Reliability Council of Texas (ERCOT) and is preparing to file for an Early Site Permit with the US Nuclear Regulatory Commission. The company has engaged with local stakeholders and aims to play a key role in Texas’ energy landscape through the Texas Nuclear Alliance, an organization dedicated to accelerating nuclear deployment in the state.
Meeting Texas’ Surging Data Center Demand
Texas has seen a sharp rise in data center development, leading to unprecedented energy demands. Currently, the state houses 340 data centers consuming nearly 8 GW of power, representing 9% of Texas’ total electricity demand. In the Dallas-Fort Worth region alone, data centers are projected to drive an additional 43 GW of demand in the near future.
With Texas’ rapid population growth and expanding digital infrastructure, state policymakers are turning to advanced technologies to address future energy needs. Last Energy’s plug-and-play microreactors offer a scalable and mobile solution to meet this evolving demand efficiently and sustainably.
Expansion Beyond Texas
Last Energy has already established commercial agreements for over 80 microreactors across Europe, with half of them designated for powering data centers. The Texas project will significantly boost the company’s capacity, adding 30 additional units to its development pipeline and enabling expansion across the United States.
In addition to Texas, Last Energy is exploring nuclear energy projects in Utah. The company’s reactor technology is based on a pressurized water reactor with a capacity of 20 MWe (80 MWt). The power plant modules will be constructed off-site and later assembled on location, ensuring efficient and streamlined deployment.
Global Progress: Expansion in the UK
Last Energy’s global footprint is also expanding, with the company recently entering the UK’s nuclear site licensing process. It plans to develop four 20 MWe microreactors at the decommissioned Llynfi coal-fired power station in Bridgend County, South Wales. If approved, the first microreactor in Wales is expected to be delivered by 2027, pending the necessary licensing, permitting, and planning approvals.
A Future Powered by Microreactors
As Texas cements its position as America’s energy leader, projects like Last Energy’s microreactor initiative are set to play a vital role in ensuring a stable and sustainable power supply. With scalable and easily deployable nuclear technology, Last Energy is paving the way for a new era of clean energy solutions to support the country’s growing data infrastructure.
