Last Energy is a nuclear energy company that designs, builds, owns, and operates small modular reactors (SMRs) for industrial and commercial customers. The company's flagship product, the PWR-20, is a 20 MWe pressurized water reactor that is fully modular and factory-produced, enabling faster and more cost-effective deployment than traditional nuclear power plants. Last Energy serves as a behind-the-meter independent power producer, supplying reliable baseload electricity to energy-intensive industries including data centers, metals production, food and beverage, pulp and paper, chemicals, and cement manufacturing. The company's mission centers on making nuclear power radically simpler and more accessible by removing the burden of development, financing, and operations from customers through a power purchase agreement model. This approach aligns nuclear energy deployment with the urgent need for resilient, low-carbon power, particularly as demand from AI infrastructure and industrial growth accelerates. Last Energy's use of proven reactor technology combined with proprietary steel containment systems is designed to streamline licensing and reduce construction timelines. Last Energy represents a new generation of nuclear developers focused on decarbonizing hard-to-abate industrial sectors with firm, emissions-free power. By standardizing and modularizing the entire plant through factory manufacturing, the company aims to bring predictable costs and schedules to a sector historically challenged by both, positioning SMRs as a practical climate solution at commercial scale.
