dispatchable power because our systems are engineered for both bridge and fast response dispatchable power applications. In contrast to stranded temporary infrastructure, once our customers are fully interconnected with the grid, our power systems can continue to serve customers as a reliable, dispatchable utility-grade power source with fast response, diesel-equivalent transient performance to supplement the grid and provide industry leading reliability for protection against grid outage events. This long-term, multi-purpose design of our power systems helps customers, particularly customers with large electricity loads such as data centers, to reduce the total cost of ownership by providing multiple value streams through the full useful life of the asset. By transforming bridge power installations into assets that continue to return value to the customer, our power systems support a more enduring and economically efficient bridge power development model compared to conventional temporary generation. Highly Cost-Effective and Low-Risk Path to Increase Grid Capacity

As utility capital expenditures
surge and electricity rates continue to rise due to increased demand for electricity, our power solutions provide a highly cost-effective and low-risk path to increasing grid capacity. Traditional
grid-expansion planning often relies on long-term demand forecasts, requiring utilities to make large, long-dated capital commitments, and utilities are increasingly asking large new electricity loads—such as data centers—to share in
those costs despite having significantly shorter planning horizons. This mismatch introduces substantial risk of stranded investment, overbuilding and misaligned capacity expansion—issues that regulators have become increasingly focused on as
grid-upgrade proposals grow in scale. By contrast, our co-located distributed power systems arrive with the load itself, are typically paid for by the customer deploying the load and provide capacity
concurrent with when the load comes online, eliminating the need for utilities to build ahead of requested demand. By enabling large new electricity loads to self-fund and install our distributed power

systems, our platform increases capacity without requiring utilities to undertake costly grid upgrades in advance of demand and, once interconnection occurs, our power systems remain in place as
a stable source of power supply for the grid that reduces or defers the need for further capital investment by utilities on grid expansion and helps moderate system-wide electricity rate impacts for existing customers. As a result, our power systems
can help accelerate the interconnection timeline as utilities benefit from our bridge power solutions by securing new electricity load and associated revenues earlier, and customers benefit from dependable, distributed power while avoiding lengthy
delays associated with traditional grid expansion. We have successfully deployed this approach for years, repeatedly demonstrating that customer-funded, distributed power systems can compress timelines by delivering immediately available capacity
that can relieve near-term grid constraints. This proven model is now being embraced by leading markets such as PJM and ERCOT, where regulators, utilities and ISOs are increasingly adopting similar approaches to facilitate faster, lower-risk
interconnections. This dynamic creates a mutually reinforcing outcome—reduced capacity planning and capital-deployment risk for utilities and a faster, more predictable path to power for customers.

Highly Reliable Path to Resilient, Firm Power

We believe our ERock Platform’s proprietary generator and operating software technology delivers a highly reliable path
to resilient, firm power. Our power systems are designed for continuous, fault-tolerant operation—meaning they can maintain power output even when components fail or experience abnormal conditions—delivering reliable power when the grid
is not available and provide backup power with lower emissions and noise than diesel alternatives. Our backup power solutions offer high operational reliability with inherent redundancy for fault tolerance and concurrent
maintainability—meaning critical components can be serviced, repaired or replaced without shutting down the system—to facilitate deployment in mission-critical backup applications. Fueled by natural gas delivered through underground
pipelines with no runtime limitations, our power systems have proven capable of delivering uninterrupted power through hurricanes, winter storms and everyday grid outages. As grid outages have become longer and more frequent, and where fuel
deliveries can be delayed during severe weather, we deliver proven backup power solutions that keep critical facilities online during grid outages and emergencies.

Our Generator and Software Technology

We provide reliable, resilient and cost-effective power primarily through a proprietary, tailored, integrated power systems
delivered through our ERock Platform, a comprehensive offering consisting of our generator and software-enabled O&M and asset management services described below.

At the core of our power systems is our RockBlock, a modular, distributed generator string that incorporates our proprietary
natural gas engine, scales in 0.5 MW increments from 1.5 MW to 3.5 MW per RockBlock and is assembled in-house. Our RockBlock systems convert natural gas from local underground pipelines into electricity
through a combustion process and are capable of continuously operating at their designed capacity with 99.999% reliability. Our RockBlock systems are engineered for maximum cost efficiency through their modular design and standardized kit, which
supports rapid delivery, field construction and scaling. Our power system units feature a patented design that occupies approximately half the footprint of comparable natural gas units, while maintaining low sound levels across varying applications
and achieving diesel equivalent transient performance, while meeting stringent local emissions standards, including CARB-DG compliance, one of the most rigorous emissions standards in the United States.

Complementing our generator technology is Granite, a proprietary software that is embedded in our power systems and enables us
to use operating data to improve operations for high reliability at a lower cost. Granite architecture is a combination of real-time device data collection as well as distributed and aggregated data process and analytics. At the device level,
Granite captures real-time data from our power systems’ ECU, controllers and balance of plant at sub-second intervals—far faster than typical SCADA systems—and uses advanced analytics to
enable predictive diagnostics, dynamic site-level optimization and adaptive maintenance scheduling. Granite also allows remote 24/7 monitoring and centralized control from our NOCs, supporting

thousands of assets and enabling market interactive peak shaving and grid services at distributed or aggregate levels. In addition, by comparing performance across power system units, sites and
fleets, Granite identifies operational patterns and anomalies, supporting maximum uptime and efficiency across all systems while at the same time reducing operating costs. Generators procured outside of our ERock Platform do not come with Granite
embedded in their systems.

To maintain our competitive edge, we are advancing a robust research and development
(“R&D”) pipeline designed to enhance core generator and software technology offering and expand into new energy solutions that meet evolving customer needs. Our roadmap builds on the success of our RockBlock systems, with the goal of
delivering greater reliability, simplified installation and improved operational flexibility, integration with other onsite energy technologies, such as battery energy storage systems, as well as additional, complementary products. A key focus is
the continued evolution of Granite, with the goal of delivering higher reliability through predictive diagnostics, preventive maintenance and dynamic integration of distributed assets into a unified system. These innovations are intended to allow
customers to optimize performance, reduce operating costs, and accelerate deployment timelines, while positioning ERock as a leader in scalable, intelligent power solutions for the future.
