Last Energy Secures $40M Series B to Scale Modular Micro-Nuclear for Data Centers and Industry
The energy sector faces significant sustainability challenges, particularly in high-demand areas like heavy industry and data centers, which struggle to secure reliable, clean, and affordable power. Traditional renewable energy sources often fall short in these areas due to their intermittent nature and storage requirements. Nuclear energy, despite its high potential, has been hindered by long development times and high costs.
Last Energy, a Washington D.C.-based company, aims to address these issues with its innovative micro-nuclear power solutions. The company is developing small, modular reactors (PWR-20), which offer a cleaner, scalable, and economically viable alternative for energy-intensive sectors. These reactors are designed to be mass-manufactured, rapidly assembled, and deployed at a fraction of the cost and time of conventional nuclear power plants. By leveraging modular technology, Last Energy can offer reliable baseload power with minimal land and infrastructure requirements, making it especially attractive to data centers and heavy industry.
The company’s first product, the PWR-20 micro-nuclear power plant, is composed of prefabricated modules that can be assembled like “LEGO kits” on-site, significantly reducing the complexity and cost of nuclear deployment. This design allows Last Energy to bypass traditional energy grid upgrades, providing clean energy directly to industrial sites. The company’s reactors promise to address the growing energy needs of AI-driven data centers, which have become a major focus due to their intensive electricity consumption.
With $40 million raised in its recent Series B round, Last Energy is on track to deploy its first plant by 2026. This funding will enable the company to scale its operations and meet its goal of building 10,000 units over the next 15 years. Investors such as Gigafund and Autodesk Foundation back this effort, recognizing the potential for Last Energy’s technology to revolutionize clean energy production and drive significant decarbonization efforts in industrial sectors
