FAQ
Target Technical Specifications
How much energy does the PWR-20 produce?
The PWR-20 is designed to deliver 20 megawatts of electricity output (MWe) and 80 megawatts of thermal energy (MWt).
How big is the power plant?
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.
What type of reactor does Last Energy 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.
What type of fuel does the PWR-20 use?
The PWR-20 uses sub-5% low enriched uranium fuel in proven PWR fuel assemblies, which reduces uncertainty in licensing and fabrication.
Plant Construction and Operations
What is the refueling process?
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.
What is your approach to safety and containment?
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 physically allow for access to the interior of the nuclear equipment, thus eliminating intrusion and sabotage.
What is Last Energy’s role?
Last Energy brings a full-service model to the nuclear sector as the designer-owner-operator, behind-the-meter independent power provider (IPP).
Where is Last Energy located?
Last Energy's headquarters and primary manufacturing facility is located in Texas.
Commercialization
Where have you been focusing your development efforts?
Our development efforts have been focused on the United States, United Kingdom, and Romania, among other markets.
What is Last Energy’s regulatory approach?
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.
What kinds of contracting structures does Last Energy implement?
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.

What’s a Rich Text element?
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
Static and dynamic content editing
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
How to customize formatting for each rich text
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
