Commonly asked questions about Exowatt
Exowatt is a next-generation renewable energy company that designs and manufactures modular, full-stack energy systems. Our flagship dispatchable solar product, the Exowatt P3, captures solar energy, stores it as heat using a proprietary high-temperature sensible heat battery for long duration energy storage (LDES), and dispatches electricity on demand through a heat engine. We deliver low-cost, reliable dispatchable energy for energy-intensive applications, including data center energy.
Exowatt’s technology has 5 main value props that set it apart from other energy sources:
Expedited Time to Power: Exowatt P3 systems can be deployed behind the meter (BTM), reducing interconnection wait times and enabling customers to “bring your own power” (BYOP) with onsite energy. Systems easily scale linearly to meet growing demand.
Clean & Sustainable: Exowatt P3 Modules are powered by clean, renewable, solar energy, which can replace or offset carbon emissions. Additionally, systems don’t rely on rare earth minerals like many of the alternate energy sources.
Up to 24hr Dispatchable: Unlike wind and solar, which suffer from issues with intermittency, generated energy from Exowatt P3 dispatchable solar systems can be dispatched up to 24 hours daily or stored for later dispatch to meet site-specific needs. This enables Exowatt P3 to serve as baseload power.
Easy to Deploy & Manage: Manufactured domestically, Exowatt P3 systems are factory-built for easy deployment and require minimal maintenance over their 30-year lifespan. Integrated software enables seamless monitoring and control.
U.S. Manufactured: Modules are manufactured domestically with raw materials which are sourced domestically. This minimizes reliance on foreign supply chain while supporting the U.S. mandate for energy independence and national security.
Expedited Time to Power: Sites can utilize fully behind the meter energy to come online more rapidly in the face of extensive interconnection queues. This enables customers to “bring your own power” (BYOP) which both accelerates timelines for onsite energy and reduces wait times for interconnection.
Renewable Baseload Energy: New and expanding sites can utilize Exowatt P3 energy to provide sustainable, renewable energy as a significant portion of their baseload energy mix. Due to the built-in long duration energy storage, issues with intermittency, common in solar PV and wind, are not a concern.
Energy Optimization: Exowatt P3 systems can be paired with other energy sources including solar PV, wind, & natural gas, or grid connected to optimize energy dispatch and participate in arbitrage and VPPs.
Carbon Offset: Customers can offset their carbon-intensive activities and support sustainability goals by deploying 100% renewable energy at strategically chosen sites.
Exowatt operates in a competitive energy market where grid expansion is slow and expensive. Interconnection delays, rising power delivery costs, and challenges in siting large electricity users like AI energy or data center energy exacerbate the problem. Options like repowering old nuclear or coal plants and building geothermal or nuclear facilities face scalability and timeline challenges. Building near existing solar and wind farms is constrained by limited capacity and existing contracts. Temporary solutions like portable gas generators are costly and unreliable, while off-grid natural gas is limited by equipment shortages. In this landscape, dispatchable solar systems like Exowatt’s present a unique opportunity to deliver scalable, clean, and reliable onsite energy that meets the growing demand for AI energy and data center energy.
The Exowatt P3 system captures solar energy using custom optical lenses, stores it as heat by heating a solid block material (long duration energy storage), and converts it into electricity using a heat engine.
Our software provides real-time monitoring and control for Exowatt P3 systems, enabling seamless integration and scaling across various applications, including intelligent dispatchable energy optimization.
Yes, Exowatt systems can operate both on-grid and off-grid. This flexibility supports onsite energy solutions for remote locations, data center energy, and microgrids, delivering baseload energy and sustainability.
Exowatt P3 systems are designed to last over 30 years with proper maintenance, ensuring reliable dispatchable energy and support throughout their lifecycle.
Exowatt’s modular design allows customers to start small and linearly scale as their energy needs grow. This makes it an ideal solution for industries and facilities requiring baseload power and onsite energy.
Currently, Exowatt serves customers across the United States and is exploring expansion into international markets.
We prioritize projects in regions with high energy demands and favorable conditions for dispatchable solar. Ideal sites will have a Direct Normal Solar Irradiance (DNI) of 5.5kWh/m²/day (e.g. Texas, Arizona, Nevada, New Mexico, Utah, Colorado, and California).
We specialize in serving energy-intensive industries such as AI data centers, HPC data centers, and utility scale energy projects.
Exowatt provides comprehensive training for safe system operation and offers ongoing support and maintenance services to ensure peak performance. We also provide updates and technical support for the life of the system.
