FAQ

The PWR-20 is designed to deliver 20 megawatts of electricity output (MWe) and 80 megawatts of thermal energy (MWt).

The physical footprint of one PWR-20 is less than 0.5 acres, or less than one-third the size of a standard football (soccer) pitch. The compact footprint allows for location at customer facilities with minimal land use.

Last Energy uses the pressurized water reactor (PWR) platform, the same base reactor technology that currently provides nearly 10% of global electricity, operating across 300 installations in over 25 countries. PWR design leverages established fuel pathways and safety principles, minimizing technical risk and accelerating commercialization.

The PWR-20 uses sub-5% low enriched uranium fuel in proven PWR fuel assemblies, which reduces uncertainty in licensing and fabrication.

The PWR-20 is not designed for refueling. Each nuclear island is fueled to operate for approximately 6 years. After this 6-year cycle, a replacement unit is installed aside the existing nuclear island. This process is designed to eliminate the need for human contact with nuclear material during operation, refueling, and decommissioning.

Last Energy believes that safety, waste management, security, and non-proliferation concerns can be addressed by the containment structure of the PWR-20. The structure is designed to be fully casked at the beginning of operation to limit radioactive material handling, with hermetic seals designed to eliminate radiation escape. The design does not physcially allow for access to the interior of the nuclear equipment, thus eliminating intrustion and sabotage.

Last Energy brings a full-service model to the nuclear sector as the designer-owner-operator, behind-the-meter independent power provider (IPP).

Last Energy's headquarters and primary manufacturing facility is located in Texas.

Our development efforts have been focused on the United States, United Kingdom and Romania, among other markets.

Last Energy uses a portfolio approach to operationalize regulatory approvals, which, combined with the Department of Energy pilot program participation, positions Last Energy for near-term progress, rapid operational milestones, and multiple shots on goal. This portfolio approach is designed to protect Last Energy against political shifts and diversify opportunities for success.

Last Energy's go-to-market strategy entails selling heat and power as-a-service through Power Purchase Agreements (PPAs). These long-term PPAs will be designed to provide predictable cash flows and enable project-level financing for multi-billion dollar buildouts.
