Last Energy
Last Energy provides decarbonized, reliable, and affordable nuclear energy through a full-service delivery model, utilizing the innovative PWR-20 modular reactor to serve energy-intensive industries and utilities.
Services
Last Energy provides a full-service delivery model for decarbonized, reliable, and affordable nuclear energy. The company manages all aspects of project financing, development, delivery, licensing, and operations and maintenance of power plants. The energy solutions cater to both industrial customers and utilities using the PWR-20 power plant to provide baseload power and a Behind-the-Meter solution. Customers benefit from time-matched commitments, price stability, and zero-carbon energy through power purchase agreements (PPA) and virtual PPAs.
PWR-20 Reactor Technology
The PWR-20 is a factory-produced, modular power plant designed for quick on-site assembly. It generates 20 megawatts of electricity (MWe) and delivers up to 83 megawatts of thermal energy (MWt). Constructed for scalability, the PWR-20 uses a single loop pressurized water reactor (PWR), operates with low-enriched uranium (LEU), and features a 72-month fueling cycle. The design focuses on operational predictability, simplifying the nuclear licensing process. The PWR-20 has a 95% capacity factor and a design lifespan of 42 years, extendable through further evaluations.
Applications and Industries
Last Energy’s nuclear energy solutions serve a range of energy-intensive industries, including data centers, construction materials, metals, manufacturing, chemicals, and pulp and paper. The PWR-20’s modular design enables versatile applications such as electricity generation, district heating, process steam, and absorption chilling. The compact footprint and air cooling system allow for near-universal siting, making it suitable for industrial applications without the necessity of proximity to water bodies.
Global Development Efforts
Last Energy is currently focusing its development efforts in the United Kingdom, Poland, Romania, and the Netherlands. The company has announced plans for a fleet of 34 micro modular nuclear power plants across the UK and Poland. The centralized manufacturing and fabrication facilities are located in Texas, enabling efficient production and assembly. Last Energy has secured $25 billion in contracts for small modular nuclear reactors in Europe, demonstrating its commitment to facilitating industrial decarbonization through advanced nuclear technology.
Innovative Delivery Model
Last Energy stands out by innovating on the delivery model rather than the reactor itself. The company offers a factory-fabricated power plant–the PWR-20–designed for road transport and rapid on-site assembly. This model accelerates the time to operation, aiming for a 24-month delivery window from the final investment decision. The streamlined approach includes complete project management from site evaluation through final commissioning, underscoring Last Energy's commitment to integrating proven technology with operational efficiency and adherence to regulatory standards.
